Pioneer Elite PRO-940HD Plasma HDTV & HP MediaSmart SLC3760N LCD HDTV Review


Who says you can't stream HDTV?

As more consumers embrace high-speed home networking and video downloads, one question is gaining prominence: Can't we view this content on something a little more substantial than our computer monitors? Yes, you can, thanks to the digital media receiver, which is a device that lets you stream video, photo, and music files from your computer to your television.
The digital media receiver comes in many forms. Companies like D-Link, Hauppauge, and Acoustic Research sell standalone boxes that connect directly to your TV. Other manufacturers incorporate the functionality into an A/V source component, like the TiVo Series 2 DVR, the GoVideo networked DVD player, and the Xbox 360 gaming console. No matter its shape, the media receiver talks to your PC over a wired or wireless home network, allowing access to some combination of media files.

These devices accomplish the desired goal, but, like adding a full HTPC, they force you to add yet another box and remote control to your entertainment system—or at least mandate the use of specific source components in order to enjoy the technology. A couple of display manufacturers have realized that they can eliminate the middleman and build the function right into the TV. Admittedly, this solution is only viable for someone who's in the market for a new TV, but it's a compelling option nonetheless. I tried out two "media-friendly" HDTVs: Hewlett-Packard's MediaSmart SLC3760N 37-inch LCD ($1,700) and Pioneer's Elite PRO-940HD 42-inch plasma ($3,300).

Learning to Share
In terms of their media-sharing functions, these two TVs are more similar than different. Both are designed to work with PCs and media servers that support DLNA, UPnP, or Windows Media Connect. For this review, I mated the TVs with Niveus Media's new Rainier Media Center PC, so I focused on how to link the devices using Windows Media Connect, a PC software platform that works in conjunction with Windows Media Player to organize and stream files to remote devices. If you have Windows Media Player 10 or 11, chances are you already have Windows Media Connect on your PC. I did. However, if you don't, HP is kind enough to include a software disc with the TV, while Pioneer expects you to find and download it from the Microsoft Website.

Setting up each set's media function involves two steps. First, you must add the TV to your home network. Pioneer's media receiver is completely integrated into the plasma's chassis; its only visible features are an Ethernet port for connecting to your home network and a USB port, which lets you access media files directly from a USB drive if you don't have a home network. In contrast, HP has essentially affixed a media-player box to the TV's backside, which adds about 2 inches of depth and requires three extra cables to link the two: HDMI for A/V signals, a control cable, and a power cable. While the Pioneer only connects to your network via Ethernet, HP lets you choose between wired and wireless (802.11a/b/g) setup. If you want to go wireless, you also need to screw on two antennas that look like gloriously nostalgic rabbit ears peaking up from behind the TV. It took several attempts before I successfully added the HP to my wireless network, even when I turned off the security, but this could have just been an issue with my network.
The second step is to enable file sharing on your PC. Once you have added the TV to your network, its name should appear on the Windows Media Connect Device page. Simply click on it, allow sharing, and set the folders you want to share. My Pictures, My Videos, and My Music are the default options, but you can add other folders—like, say, your iTunes music folder. Obviously, protected music and video files downloaded from the iTunes Store aren't compatible with this Windows-based system, but, hey, we're used to that by now. Microsoft DRM files should play. Since I used a Media Center PC, I also added its Recorded TV folder in order to stream standard- and high-definition content to the TVs.

Yes, I did say "high definition." Probably the coolest application of this technology is the ability to stream high-definition content for viewing on your new HDTV. Over a wired connection, both TVs cleanly rendered recorded over-the-air HDTV programs and a couple of WMV HD trailers. If you want to view a lot of HD video, I don't recommend you go wireless with the HP; HD playback was very choppy over my 802.11g network, but SD video played back fine. For some reason, the HP wouldn't play any of the music files that came preloaded on my Niveus Media but worked fine with music I loaded myself, while the Pioneer played every file without issue.

I preferred the layout and appearance of Pioneer's media menu, but I found the HP system more intuitive to navigate and use, due primarily to the remote. The media function seems more like an afterthought for Pioneer. Their remote lacks a dedicated button to access the media menu and hides transport controls under a flip-down panel at the bottom; plus, the track-up/-down buttons don't work within this menu. HP treats the media function as the marquee feature, grouping all of the needed access and control buttons in a logical way. They also up the ante by adding a Services menu through which you can access certain online media portals—like CinemaNow, Snapfish, and Live365.com—directly.

Lest We Forget. . .
The media functions are certainly intriguing, but they mean little if the TVs fall short in the video department. Luckily, that isn't the case. Both displays receive solid marks in the major performance categories, although there are some drawbacks inherent in their respective technologies. The HP's 1,366-by-768 resolution gives it an edge in the detail department; it's capable of rendering razor-sharp images, but it also suffers from some motion blurring, which lessens the impact of that detail in fast-moving scenes. The Pioneer's 1,024-by-768 resolution creates a slightly softer image. But I never felt I was missing anything with DVD or HD sources, and details remained intact during faster-moving scenes.

Like many plasmas, the Pioneer's green color point is way off, which gives the image a bluish-green tint. The HP's color points are quite good; its green is also off the mark, but less so than the Pioneer's. As for color temperature, both TVs exhibit a large spike at the lowest IRE levels, causing dark scenes to take on a blue tint, but this evens out with brighter images. Skintones looked natural, with no red push. You can calibrate the Pioneer to measure very close to 6,500 Kelvin across the range; we could not calibrate the HP, but I doubt we would have been able to fix the spike and subsequent dip at the darker IRE points.

Both TVs offer film modes that enable them to pick up the 3:2 sequence in 480i sources pretty quickly, resulting in only minor shimmer in my demo scene from Gladiator. The Pioneer has an adjustable scan rate; you can set it for 72 hertz, instead of 60 Hz, for slightly more natural motion. It also picks up 3:2 with 1080i sources, while the HP does not. Both deinterlace 1080i/30 correctly.

By numbers alone, the HP has a much higher contrast than the Pioneer, but this doesn't tell the whole story. Our measurements use a full-field white for light output, which can put plasmas at a disadvantage. When we measured the Pioneer with a white window, its contrast ratio was closer to 1,400:1. With real-world content, I never felt the Pioneer lacked image depth or dimension, although its light output is somewhat low, even compared with a few plasmas we've reviewed. Combine this with the glass' tendency to reflect light, and the PRO-940HD isn't the best choice for a bright room environment.

The HP, meanwhile, is capable of over 150 foot-lamberts, which is more than enough light output to watch it in a sunlit room. Thankfully, it also has an adjustable backlight so you can turn down the lamps' output when necessary. While the HP is capable of a better black level than the plasma at its minimum backlight setting, black detail was not very good in my test scenes from Ladder 49 and The Bourne Supremacy. Plus, the viewing angle is a concern; move just 45 degrees off axis, and the black level rises while image saturation drops off noticeably. These two factors hurt the HP's performance in a dark room with darker film sources. The Pioneer has good black detail and a solid black level that remains consistent at any angle, making it a better fit for a theater environment. You might notice that I've essentially just summed up the differences between plasma and LCD.

If you're trying to decide which of these media TVs to buy, it really comes down to usage, taste, and budget. The $1,700 HP renders a videolike picture, with razor-sharp images that are clean and vibrant but lack depth. Its connections and features are modest at best: one HDMI input, no VGA connection, no program guide, and no automatic aspect-ratio detection. The Pioneer's image is more filmlike, with a richer, more textured, and generally more natural quality that I really enjoyed, especially since I watch TV mostly at night. Part of the Elite line, the $3,300 PRO-940HD has a healthy list of connections and features, including two HDMI and three component video inputs, two RF inputs for the internal tuners, a CableCARD slot, the TV Guide On Screen program guide, and a fair number of picture controls. Compared with last year's PRO-930HD, this model exhibits less phosphor lag and short-term image retention, which is important if you plan to leave the media menu on the screen for long periods of time. Both TVs are priced at the high end respective to their screen sizes.

With all that in mind, I primarily view the Pioneer PRO-940HD as a theater-based media TV, one that sits in the center in your home theater system and receives streaming media from the various PCs around your home. HP's SLC3760N, on the other hand, is a great fit for a secondary room as a device that taps into your main Media Center PC and lets you stream all that great content as seamlessly and invisibly as possible.

Pioneer Elite PRO-940HD Plasma HDTV & HP MediaSmart SLC3760N LCD HDTV review:Those Who Can't. . .Cheat

Streaming media to your TV from an Apple computer is a trickier task, as most digital media receivers are PC-centric. Apple plans to enter the ring with their own digital media receiver, tentatively named the iTV, sometime in the first quarter of 2007. If you can't wait—or your heart is set on one of these media-friendly TVs—you'll have to get creative.

Elgato Systems offers a software program called EyeConnect ($91.35) that lets you stream content in your iTunes, iPhoto, and Movies folders to any UPnP media receiver. It also lets you stream TV content you've recorded with Elgato's EyeTV tuner. You can download a free 30-day trial of the software at www.elgato.com.

HP also sent me their MV2020 Media Vault ($550), a 500-gigabyte external storage drive that connects directly to your home network via Ethernet. This device can automatically back up the content on your networked computers, but it also has a MediaShare function that lets you stream its content to any UPnP media receiver, which worked very well in conjunction with the HP MediaSmart LCD. Mac owners can't use the advanced PC software to manage the Vault, but they can still use its backup and media-sharing functions through their home network. It's not an ideal media-sharing solution for the Mac, but it works.

Neither of these methods lets you stream iTunes video downloads or AAC music files, protected or not. For that, you must wait for the iTV.

Panasonic TH-42PX600U review

Model: Panasonic TH-42PX600U

Description: 42" Plasma Television, Widescreen 16:9 Format
Resolution: 1024 x 768 (HDTV)

Includes: Integrated pedestal stand and HD2D Sound Enhanced Speaker System, NTSC and ATSC (HDTV) tuners, 2 HDMI high-definition inputs and one compter 15 pin VGA input, 2 component video, 3 composite video, 3 S-Video connection.
Color: Silver and Black Bezel and casing.

INTRODUCTION

The Panasonic TH-42PX600U is contains the 9th generation panel of the ever-popular Panasonic plasma line replacing the TH-42PX500U in June of 2006. The resolution remains 1024x768 like the previous model, the highest ranking plasma TV in its price point in 2005, but Panasonic has upped the contrast ratio specification to 10,000:1 for this year's model and also increased the brightness spec significantly. Because of increased demand, Panasonic has included a second HDMI connection for this year's consumer plasma line. Panasonic even gives the TH-42PX600U a makeover to a more modern look.

With each passing generation, other top-tier plasma television manufacturers—such as Samsung, Pioneer, and Toshiba—are improving both their picture performance and overall value. Samsung and Toshiba have focused on matching Panasonic's aggressive price-point with their new models. Pioneer, on the other hand, remains focused on its first-rate picture quality and aesthetic appeal and providing a comprehensive feature set at a slightly more expensive price. This upgraded Panasonic PX600U series model compares equally with Pioneer's excellent PDP-4370HD model in features, appearance, inputs and quality while the Panasonic PX60U series lacks some of the "extras" these two offer.


PICTURE: 98/100

Like most televisions on the market today, the Panasonic TH-42PX600U came out of the box with superficially bright default picture settings. Out of the box, the picture is in a default picture mode setting of Vivid (which maximizes Contrast and Sharpness settings) and a color temperature setting of Cool. The first task before examining the picture quality of the plasma TV is to find the picture settings that get us closest to D6500K—the optimum prescribed color temperature used by the film and broadcast industry. Because Panasonic plasmas typically have a cooler default temperature setting than other brands (which often leads to a "blue push" in the white balance), the "Warm" color temperature setting is preferred for increased realism. By switching to the "Standard" picture setting (which has medium Contrast and Sharpness settings) and using a "Warm" color temperature, we quickly move much closer to D6500K. Maintaining a color temperature close to D6500K is important because it is the basis on which the rest of the picture calibrations are made.

Panasonic Plasma TV Review

Color and detail on the Panasonic TH-42PX600U was outstanding

In order to fully optimize the picture quality of our TH-42PX600U, we used a colorimeter, and a specialized software suite to calibrate the television to the Imaging Science Foundation (ISF) standard color temperature of D6500K. With this equipment, we were able to properly calibrate the picture settings on the television, and we were able to measure color temperature, color saturation, white balance, and black levels. Using these measurements as a reference point, we used the Sencore software suite to precisely calibrate the optimal picture settings for the TH-42PX600U.

The following table contains the picture settings for the TH-42PX600U after its ISF calibration. We highly suggest that you use these settings if you purchase or own this television. By configuring the television to the below settings we were able to get the color temperature to D6650K, a substantial improvement over the out-of-the-box measurement of D10000K+. Using the below settings to regulate the color temperature and white balance virtually perfects the picture of the TH-42PX600U:


Panasonic TH-42PX600U Optimal Picture Settings
Picture Mode Standard
Picture +22
Brightness +8
Color -1
Tint -4
Sharpness -14
Color Temperature Warm
Enhanced Black Level Off

Figure 1. Optimal picture settings for the Panasonic TH-42PX600U using ISF calibration.

At these settings, practically speaking, there is no further calibration needed on this model. There is no need to tinker with hiring a calibration specialist and tinkering with dangerous service menus.

Wow, once the picture was calibrated the TH-42PX600U had undoubtedly the truest picture of any television that we have tested to date. Using the HD-DVD edition of Clint Eastwood's Unforgiven on the Toshiba HD-XA1 HD-DVD player, we put the Panasonic's High Definition capability to the test. Using the Toshiba's 1080i High Def output via the HDMI connection, the picture detail in scenes from the HD-DVD were astounding. In one scene, inside a dark cabin, a fly crawls across one of the actor's cowboy hat. On a standard definition TV, it's doubtful you would notice the fly at all, but on the PX600U I could clearly make out the fly's legs as it crawled across the hat. With a high-quality 1080i HDTV source like the HD-DVD, you could literally get so lost in the details of each scene that you lose the plot of the movie: the grain of a weathered fence post, the fine textures of sweeping Wild West landscapes, the coarse stubble on Will Munny's cheeks--it's all there, and the Panasonic never misses a beat.

Panasonic's black levels have been the best in the industry for years, and the TH-42PX600U is no exception. Unforgiven is a challenging movie in that regard, because at any given time you may be sweeping from a scorching Western landscape to the interior of a oil lamp-lit saloon. From one scene to the next, we were impressed by the level of detail we could see in even the darkest scenes. This is an important strength for Panasonic because the dark matter detailing of the plasma television impacts the picture's realism as much as its color reproduction ability.

Panasonic HDTV Plasma Review

Panasonic Plasmas are unmatched in dark scene performance; the PX600U series is no exception

The black levels are really put to the test late in the film, when Munny (Clint Eastwood) returns to the saloon to exact revenge for his friend Ned. In true gritty Western style, the camera shifts to show Munny emerging from shadows at the saloon door. Every detail is portrayed impeccably by the TH-42PX600U: the sheen of sweat on Munny's stubbled face, the fibers of his duster jacket, even the subtle glint of lamplight from the blued gun barrel. This smooth transition between dark shades can be attributed to the 3,072 shades of gradation in the TH-42PX600U—an attribute that sets Panasonic plasmas apart from the 2nd tier plasmas manufacturers. It is also important to note that as the camera pans from face to face in the dark saloon, the bright oil lamps appear very clearly in the dark room without any elements of false contouring, a problem that can occur when plasmas try to display bright objects with dark surroundings.

After we performed the ISF calibration to optimize the television's picture, we decided to measure the TH-42PX600U's contrast ratio (light output ratio of "whitest white" to the "blackest black") for ourselves. We used a signal generator to display the checkboard test pattern for contrast, and the accompanying colorimeter to measure the light output from each sample. While the black levels on the TH-42PX600U are quite impressive, our measured contrast ratio for the television was 788:1 - one of the highest true contrast ratios we've measured! From our experience, all TV manufacturers, including Panasonic, greatly "enhance" their specifications to entice buyers and "beat" the competition. There are few standards for their measurements.

As is made evident by the Unforgiven HD-DVD, the quality of high-definition content on the 42PX600U is unparalleled. When we auditioned conventional DVDs including Kill Bill, part I in Progressive-Scan 480p, we saw similar sharp, detailed pictures with excellent contrast, but obviously not to the extent of the HD-DVD. It is important to note that the 42PX600U does not display the visual artifacts easily noticeable on lower-tier plasma displays with a conventional input source. Despite the upconversion necessary to display a 480p picture on a 1024 x 768 HDTV screen, we never noticed any edge artifacts or jagged motion on the PX600U.

The ATSC tuner pulls in digital broadcasts. When we watched the Evening News in high-definition, the image was very clear, and the news anchors' faces had accurate flesh tones. When they cut to reporters out in the field, the detail of their surroundings was excellent. Algorithmic scaling to full picture size was excellent. When we changed the channel to view the same program in regular definition, the picture was somewhat fuzzy. The image degradation is probably caused by the lower bandwidth emitted by local stations for their analog channels.


OTHER CONSIDERATIONS: 96/100

The PX600U series is a slight step up in aesthetics from the PX60U series. It's got that Pro appeal that says it costs more with black banding around the screen and a thin silver finish bezel surrounding the black banding. The excellent 31 watt audio system which incorporates 2 subwoofers is hidden in the casing. This is an 11 watt upgrade from the PX60U series. The new look of the TH-42PX600U is definitely very modern, and it has significant "pop." The unit is 42.5 inches wide, and 27.2 inches in height (29.3" with the table stand).

For the TH-42PX600U, Panasonic improves its already user-friendly remote control. The easy-to-find buttons are generally in the same place as the last model, but now they are bigger and easier to find without looking. The remote feels good in your hand, has intuitive controls, and would be a serviceable solution as a universal remote control.

The on-screen menu system on the TH-42PX600U is relatively unchanged from Panasonic's previous generation TH-42PX600U, however it has the new electronic programming guide included in this upgraded model. I found the whole system very intuitive. When the Menu button on the remote control is pressed, the main menu options—Picture, Audio, Timer, Lock, Memory Card, and Setup – appear in an easy-to-read fashion. The Picture menu includes the picture controls required to calibrate the picture. The Audio menu features Bass, Treble, and Balance adjustments. In the Other Adjust sub-menu for Audio, you can choose Surround for a marginal Virtual Surround Sound experience. Also in this sub-menu, the users with Home Theater systems may choose to simply turn off the internal speakers of the television in favor of your own surround sound set up. The invisible speakers system will complement this choice.

When viewing material from a non-HDTV source, aspect ratio becomes a concern with the TH-42PX600U. There are four modes for adjusting regular 4:3 inputs to the widescreen 16:9. The first option is to watch the source in its native 4:3 ratio with the sidebar "letter-boxes." Panasonic allows the customer to change the color of the letter boxing, and it is wise to change these to black if you want to use this aspect ratio setting. With Full mode, the picture is uniformly horizontally stretched across the screen. With Zoom mode, the plasma cuts off the top and bottom of the screen and zooms in so that the sides match with the ends of the screen. Obviously, most people will not choose this setting because they don't want to lose any of the picture. The final choice is the most popular—Just mode - which most likely stands for 'justified". Just mode stretches the picture horizontally but uses a special stretching algorithm to minimize distortion, particularly in the middle of the screen. With this method, distortion on a 4:3 source is virtually undetectable and I have found this the preferred way to watch even 4:3 programming after a little break in period for your eyes to adjust.

Panasonic adds a front composite video input and digital card slot input at the front of the panel for this HDTV plasma. This is particularly useful if you want to display images from a digital camera or a source that you will use only temporarily. The 42PX600U also contains a 15 pin VGA input for convenient computer hook up and use. There is also an SD (secure digital) memory card slot for viewing digital camera and camcorder content.

Another important addition to the TH-42PX600U plasma TV is the second HDMI input. Because of the increase in popularity of new HD and Blue Ray DVD players and digital high-definition cable and satellite boxes which already support the HDMI format. One additional input over the PX60U series is the cable card slot for those who are adamant about losing that cable box. The plasma also includes digital audio output capabilities. Even though one cannot choose input sources directly on the remote, it is easy to navigate to the chosen source.

One more included feature of the TH-42PX600U series over the TH-42PX60U series is a PIP (picture in picture) option. Though rarely used, there are those football game days when sound is not a must but seeing both games is!

The two speaker two subwoofer audio system totals 31 Watts of power and are more than adequate for home viewing. This is an 11-watt upgrade over the PX60U series. With the beefier sound system, you notice discernable channel separation and a better soundstage than you might expect from TV speakers, and enough bass response to procide some punch. Panasonic offers a Virtual Surround option for the TH-42PX600U and its performance is robust for such a in-built system. While many home theater aficionados will want to use their own surround sound speaker system, the included speakers will impress the average consumer.


VALUE: 98/100

The Panasonic TH-42PX600U is an excellent value piece. It contains all of the features of the Pioneer PDP-4370HD but for much less money. It has the pro quality feature set of upgraded sound system, cool looks, cable card input, and computer compatibility and input that the TH-PX60U series lacks and at only a couple hundred dollars more.Panasonic introduced the TH-42PX600U with an MSRP of $2,999 at specialty retailers, but it can be found close to $2400 from some authorized Internet dealers.

Olevia 747i LCD 1080p Television Review



For a relatively new brand, Olevia has made a fast start. When I attended the launch of its new assembly plant in Ontario California recently, I was impressed by the efficiency of the operation, not to mention the gutsy move to open an assembly plant in the continental U.S. rather than, say, just across the border in Mexico. This says a lot about the confidence that Olevia, and its parent company Syntax-Brillian Corporation, has about its future.
When Michael Fremer reviewed the Syntax-Brillian 6580iFB03 65" LCoS rear projection television back in August, he described a picture "so good I looked forward to seeing it every time I turned on the set." Syntax-Brillian's bread and butter, however, is not in rear projection; but rather in Olevia's flat panel LCD designs.

The 1080p Olevia 747i ($3,999, 47" diagonal) is the top of the company's wide range of LCD displays (there's also a smaller, 42" 7 Series model, the 742i). Can it live up to the standards set by its bigger, more expensive RPTV siblings?

The World is Flat
With a net weight of 128 lbs. without its (included) stand, the Olevia 747i is astonishingly heavy for an LCD flat panel. LCDs tend to be lighter than plasmas of equivalent size (Pioneer's Elite PRO-FHD1 50" 1080p plasma weighs in at a svelte 88 lbs, though it does lack a built-in tuner and speakers), but that isn't the case here. If you plan on hanging the Olevia on the wall, you'd better choose a very strong mounting bracket and a very sturdy wall.

While the bottom-mounted speakers keep the width of the set narrow, they do give it a slightly chunky appearance. Not to worry: the speakers can be removed and mounted on the sides using an optional conversion kit, or even left off entirely. You could even use the onboard digital amps (rated at 26 Wpc, though no response or distortion is specified) to drive external speakers if you choose (the speaker leads are readily accessible). I don't know of any competitor that offers this much flexibility.

When it comes to features more significant than size, weight, or form factor, Olevia didn't pinch pennies with the 747i. The fun starts with their decision to use the Silicon Optix Realta HQV video processor. Based on Teranex technology, the Realta's pixel-based scaling and deinterlacing (including the all-important 1080i-to-1080p conversion) largely eliminates video processing as a limiting factor in picture quality—at least at the current state-of-the-art.

According to Olevia, each set leaves the factory with its 6500K setting correctly calibrated to 6500K, with measurements made across the full brightness range, not just at a single point. I saw the calibration "tent" on my factory visit. A dark environment is used for calibration so that non-contact measuring devices can be used. The Olevia tech with whom I spoke said that they do not use contact devices—those suction cups fitted with sensors that are the staple measuring device of most calibration techs. He argued that the pressure from the cups—which are often held securely in position by hand—subtly distorts the front surface of the screen and affects the readings. I'm sure this will be a controversial claim, but it does indicate Olevia's dedication to detail.
In addition to two antenna inputs and the usual video and S-Video connections, there are three component (Y-Pb-Pr) inputs (one of them on a VGA/computer style connector), and two HDMI connections. There is also an RS-232 jack. The firmware is upgradeable via a USB port. The set does not have a CableCARD slot. (The current CableCARD format has been falling out of favor because it does not offer two-way interoperability for such features as program guides and pay-per-view).

Most of these connections are located at the rear of the set but readily accessible from the side when the set is mounted on its stand. The two RF (antenna) inputs, digital audio outputs (both coaxial and TosLink optical) for use with the set's onboard ATSC tuners, L/R analog audio outs, a subwoofer output, and a headphone output are located further around back, facing down. (Placing the headphone jack around back, facing down, is an odd choice for a feature that needs to be readily available after installation.) As with all flat panel displays, none of these jacks are easily accessible in a wall mount. In that situation all connections should be made before positioning the set on its wall bracket.

While Olevia specifies only a single digital audio output, I found two (TosLink optical and coaxial) and changed the listing in the specs at the end of this review accordingly.

The 747i also includes two onboard, over-the-air, Clear QAM ATSC/NTSC tuners. You can display two HD stations simultaneously.

The only manual that came with my sample of the 747i was on a CD-ROM. While this might be useful in some circumstances, I find a printed manual far more useful. (You could, of course, print out all 79 pages of the CD-ROM manual, using your own paper and ink!)

The Usual, and Not So Usual, Suspects
I'll conserve bits here by not going into the usual list of features found in most sets—things like channel setup, Parental Control, aspect ratios, channel guides, PIP/Split Screen, etc. While there are no arcane features such as a slot for viewing the contents of a digital photo card or a printer for printing them, the set offers all the special features and any sane TV viewer might need.

The Olevia also provides an unusual way of presenting and controlling these features. The set's on-screen display starts with a figure of a rotating wheel in the upper left hand corner of the screen. It looks like one of the spinning drums in a slot machine. There are four surfaces on this indicator, for four different submenus: Picture, Audio, Screen, and Setup. The Up and Down buttons on the remote's navigation section rotate the wheel to the submenu you desire, while the Left and Right select the option you want within that submenu. Once there, the Enter button calls up the adjustment control for that option.

This arrangement is clever, but for me too clever by half. It does have the benefit of keeping the screen clear of clutter while you're navigating through the options. But it didn't feel intuitive. And with some of the options I was never quite sure if I had turned them on or off. As far as I could tell, a red border around an item indicated it was on, and a green border indicated off--not at all intuitive to my way of thinking.

For most parameters you may enter different settings for each input, but some settings operate globally or near-globally. For example, the color temperature setup you choose for HDMI will apply to both HDMI inputs.

One serious ergonomic shortcoming is that while your changes to the video settings are accompanied by an on-screen "slider" indicator with a marker above it showing the last saved setting; there are no number designations for the settings. If you dial in a reasonably satisfactory setup but want to experiment further, the lack of such numbers make it difficult to return to your original settings. And as soon as you exit the menu for a particular setting—brightness, for example—the marker moves to the new position.

Apart from the usual picture adjustments, the Picture menu includes a Lighting control that adjusts the image for a dark, medium, or bright room (I used Dark Room for virtually all of my watching). The color temperature control provides both factory and User settings for 6500K and 9300K. The User adjustments provide both high (Gain) and low (Offset) adjustments for red, green, and blue. (The lack of number designations for the settings described in the above paragraph also applies to the user menu's color temperature adjustments, which is certain to drive calibrators up the wall.)

An oddly named "Idea" submenu includes controls called Black Level Extender, White Peak Limiter, and Contrast Enhance. The On/Off status of these three controls, which had relatively subtle effects, were hard to determine from the on-screen indicators. I solved that problem by leaving the Idea menu Off. It didn't help that the function of these controls (and a few others, as well) weren't well described in the manual. The description of the White Peak Limiter, in particular, read like an outtake from Borat: "To limit the signal amplitude varying degree resulted in brightness over saturation."

The remote control's buttons are backlit, though with the common limitation that the labels for the actual functions of many of the controls are on the body of the remote and therefore not illuminated. Some controls are well located and comfortably sized, but others are too small and too close together for error-free operation. On the upside, many of the set's more frequently used functions may be accessed directly from the remote rather than going into the sometimes frustrating, main on-screen menu system. The remote may also be programmed to operate up to seven additional components by inputting the appropriate codes.


Syntax –Brillian devotes a page in the owner's manual to the subject of dead pixels. They allow up to 12 bad pixels, and will exchange a unit when a set is delivered with more than that, but they cannot guarantee that the replacement unit will be 100% free of the problem. At least they are up front about this. No manufacturer can guarantee a perfect complement of pixels, though some choose to ignore the issue altogether. (I have almost never experienced a bad pixel in a review sample, and saw none in this one.)

Performance
I usually prefer to get the negatives out of the way first in a review, and the Olevia does have a few shortcomings. The first was not surprising. The set's deep blacks simply aren't very deep. Uniformly dim scenes have too much medium gray and too little black. The under deck scenes that open Master and Commander: The Far Side of the World lack punch. If you're a fan of Dark City, or film noir, this may not be the set for you.

Fortunately, such scenes are relatively rare in most movies, though there are more of them in modern films than older ones. Blame today's faster film stocks, which encourage cinematographers to shoot in available light. Whenever such scenes turn up, most LCDs, including the Olevia 747i, look like they are overlaid with a gray fog that lightens the scene and obscures shadow detail. But if the scene has enough bright highlights to give the eye a reference, you don't notice this "gray fog" as much. But it's still there; those highlights simply mask it a bit. And shadow detail remains marginal at best. The Olevia is a little worse in this respect than the two most recent high-end LCD displays I have reviewed, the Sony BRAVIA KDL-46XBR2 and the JVC LT-46FN97, but it's in the same ballpark.
While Olevia specifies a 178-degree viewing angle, both horizontal and vertical, it's a tad optimistic. (According to Olevia, that spec comes from the panel manufacturer, LG Phillips.) While the image is still watchable at a fairly wide angle, the image starts to lighten, the contrast drops, and the colors fade when you're only slightly off-axis. From a comfortable viewing distance, three on a couch centered on the set should have no problem enjoying the picture. But the middle will still be the "money seat."

There are some minor uniformity issues. I saw no discolorations on the screen: The black and white HD DVD transfer of Casablanca looked beautiful, with a subtle but appropriate sepia shift and no odd, irregularly tinted blotches. But I did see some dark, vertical, ghostlike bands on some material at mid brightness levels, both on test patterns and on large areas of solid color, like deep blue sky. They weren't easy to spot on most programming, however, and even when I was looking for them I seldom saw them. And on a full black screen there were small, slightly brighter areas in the bottom corners. Again, I never noticed this with program material.

But for the most part this set produced stunning images. It was no surprise that with its Silicon Optix video processing the Olevia passed all of my usual scaling and deinterlacing tests with flying colors, scoring from very good to excellent on all of them. Every cadence test on my HQV Benchmark test disc was smoothly reproduced—again, not surprising since this test was produced by Silicon Optix to show off the capabilities of its processing solutions.

The Olevia's three optional noise reduction settings were also useful, minimizing noise while doing little damage to picture's resolution. Most of the time I recommend leaving this noise reduction feature Off, but it's effective if you ever need it.

If there's one word I could choose to describe the Olevia's picture, it would be silky. It never lacks for detail, but the image is so smooth that the resolution never seems forced. It has a natural degree of pop and vividness. Less, it's true, than you'll see from a good plasma display, but not everyone finds the vividness of plasma to his or her liking. Yes, you can make the image on the Olevia less natural with a poor setup, but it's to the company's credit that it doesn't give you the traditional picture "modes" offered by other manufacturers, modes with names like Vivid, Gamer, Dynamic, etc. What Olevia does give you is an excellent picture out of the box and the controls needed to make it even better.
High-definition from my cable system on the Olevia ranged from satisfactory to superb. Such a range of quality is not unusual with any program source, but if you see a great looking HD program on the Olevia, you'll know it. I have some of this year's Macy's Thanksgiving Day Parade on my HD DVR, and it's beautifully reproduced on the Olevia, with gorgeous color, natural flesh tones, and a sharp but natural image. And the set will do justice to a good HD movie transfer, as well. About a Boy is an odd movie, but it has a surprising number of reference quality images. The 747i got it all, including scenes inside a supermarket with its well-stocked rows and stacks of small, brightly colored, crisply detailed merchandise.

The Olevia earns top marks for HD sports, too. LCDs have a reputation for slow response time, which causes motion smear. I watched more than my fair share of football on this set and was never bothered by motion smear. I'm sure it's there, and if viewed side-by-side-by-side with, say, a CRT, it probably wouldn't be hard to spot. But viewed and judged on its own, whatever motion smear the Olivia might have never bothered me.

Even standard definition DVD looks beautiful on this set. Jurassic Park III has always been a great video transfer, the best looking of the Jurassic Park series. It also has many scenes of bright green foliage that can be tough on digital displays. The Olevia did a great job keeping those greens realistic. It also handled the rest of the transfer with ease, edging very close to the look of a high-definition source in depth, detail, and color.

The recently released DVD of Pirates of the Caribbean: Dead Man's Chest may not be high-definition either, but that doesn't mean it looks soft. Its bright scenes are given a first-rate treatment on this set. Even most of the dark scenes, and there are plenty of them here, fare reasonably well because they are lit in a way that adds highlights to important details. And while a few of the darkest scenes look too gray, you can always follow what's going on.

Mediocre program material, which includes much of today's standard definition, analog cable offerings, looked okay on the Olevia. The set didn't work miracles with such material, but most of it was at least tolerable. Nevertheless, as you get more accustomed to HDTV and even the best DVDs on this set, you'll definitely find yourself less drawn to TV Land reruns of Green Acres and Gilligan's Island.

I recently reviewed the 46" JVC LT-46FN97 LCD flat panel set, and it was still on hand in the early stages of this review. Compared to the Olevia, the color of the two sets was so close (after calibration) that I wouldn't want to have to choose between them. On bright and medium bright scenes the two sets look similar in contrast. The Olevia was a bit more vivid, three-dimensional, and lush, but it was a very close call. On darker scenes, however, the JVC pulled slightly ahead, with marginally darker blacks and better shadow detail.

Conclusions
The Olevia is not without flaw. It suffers from some of the weaknesses typical of most LCD sets: poor black levels and less than optimum off-axis performance. But it does have excellent color, great detail, an image that is both compelling and easy to watch for hours on end. It's a worthy flagship for a brand that I suspect we'll be hearing a lot more about in the future.

Highs
Outstanding color
Fine three-dimensionality with crisp detail
Video processing second to none
Two HD tuners

Lows
Mediocre blacks and shadow detail
Image deteriorates noticeably when viewed much off-axis
On-screen menus can be frustrating

Olevia 747i LCD 1080p Television:Tests and Calibration

The Olevia 747i's black and white (luminance) and color response, in both HDMI and component, extended up to the maximum burst frequencies from my AccuPel HDG-3000 test pattern generator at all resolutions (6.75MHz for 480i, 13.5MHz for 480p, and 37.1MHz for 720p and 1080i). The result with the 1080i burst, in particular, was as good any we have seen from a display of any description, including front projectors.

With HDMI at 480i, the set did not respond properly to the generator- the patterns were visible, but enlarged and off-center. This was odd as the Olevia did respond properly to a 480i HDMI output from my Pioneer Elite DV-79AVi DVD player.

The set looked excellent on sharpness patterns at all resolutions, with single pixel lines crisply resolved where present, particularly at the high-definition resolutions. The minimum setting of the Sharpness control was optimum, though its action was mild, and an increase to a setting as high as 50% did not result in serious artifacts on normal program material.

But there was one odd result, which is shown in Figs. 1 and 2. With 1080i HDMI (Fig.1), all the horizontal lines in the sharpness pattern were accompanied by additional, one pixel-width horizontal lines. As you can see, these "phantom lines" were as crisp as the lines in the pattern itself, and not the sort of shadowy lines you would see with ringing. They were also visible from other AccuPel 1080i HDMI test patterns having sharp horizontal edges.

Fig. 1

Fig. 2

The same 1080i pattern is shown in Fig.2 as reproduced through an HDMI connection to the Sony VPL-VW50 ("Pearl") 1080p projector. This is what it should look like. It's possible that there is some incompatibility between the AccuPel generator at 1080i and the Olevia. I saw no sign of this artifact in any other situation, including normal 1080i program material via HDMI, test patterns in 1080i component, or any type if source at other resolutions.

The primary RGB color points on the Olevia were very close to ideal. Green was off the most, but far less oversaturated than most modern digital displays we measure. The secondary color points for cyan and magenta were off a bit more (though yellow was excellent), but not enough to make an issue over.

In its 6500K color temperature setting, the pre-calibration gray scale (measured with our Photo Research PR-650 colorimeter), was very close to the ideal temperature (see the chart). But there was a bit too much green in the readings, something that the color temperature numbers alone do not show. A slight recalibration in the 6500K User menu brought the x/y coordinates closer to the D6500 standard (x=0.313, y=0.329 on the CIE color chart across the full brightness range).

I measured a peak contrast ratio of 915:1 (72.32 foot-Lamberts peak white, 0.079fL video black). This is lower than the specified Dynamic Contrast of 1600:1, but it isn't clear what Olevia means by Dynamic Contrast. My measured 915:1 peak contrast ratio is better than other flat panel displays I have tested recently (including the Sony and JVC, mentioned earlier), but the Olevia's black level was worse (higher) than on those other displays.

Overscan averaged about 1% or less at all resolutions, in both HDMI and component. A cropping control is provided to increase this to about 3.5% in case noise or other artifacts intrude at the edges of the picture. But engaging the cropping control does affect resolution. The difference is most evident at 1080i. Fig.3 shows multibursts at 18.5MHz (left) and 37.1MHz (right) without cropping. Fig.4 shows the same two bursts with cropping engaged.

Fig. 3

Fig. 4

It is not uncommon for such overscan/cropping controls to affect resolution So this is less a criticism of the Olevia than a caution against using its Cropping control unless it is needed to eliminate the noise that occasionally turns up at one or more edges of an image.

JVC LT-46FN97 LCD

  • $3,500
  • 46" LCD
  • 1920x1080
  • Key Connections: Dual HDMI and component inputs, two i.LINK IEEE1394 in/outs, one PC input
Features We Like: 1080p resolution, OTA and CableCARD HD tuners

Features We Miss: Doesn't accept 1080p signals

The editors at our sister publication UAV loved this JVC for its relaxed, natural looking imagery. But that's not to say it's not sharp- this set consistently bordered on that fabled "looking out the window" territory. While black weren't as good as the best plasmas, and we're bummed when a display can't accept 1080p signals, the colors rivaled the best digital front proejctors we've seen, natural and respectably accurate. This set is a potent cocktail of price, size, features and performance making it a terrific value in a 1080p flat panel.

HP MD6580 and MD5880 1080p Rear Projection HDTV Review


HP have now discontinued their rear projection HDTVs including the two reviewed here however, they have introduced a new line of LCD and Plasma Flat Panels.

Hewlett Packard’s (HP) MD6580 and MD5880 1080p Rear Projection HDTV’s are part of the popular and growing range of lower cost, high definition, rear projection televisions incorporating microdisplays using DLP, LCD, or LCoS technology.

Both the MD6580 (65 inch) and the MD5880 (58 inch) are DLP microdisplay powered with a native resolution of 1920 x 1080 pixels. Image processing is powered by a single Texas Instruments HD4 DLP chip.

Picture Technologies Used

  • Wobulation For both models Hewlett-Packard have used their “Wobulation” technology for reducing the cost of high resolution displays. Texas Instruments have a similar technique which is trademarked as SmoothPicture which is used in marketing by some manufacturers. Drawing from their experience with overlaping of printing ink, HP use Wobulation to double the horozontal image resolution from any video source. Each frame is actually produced by the projection of two subframes slightly offset (by the wobbling back and forth of the DLP chip micromirrors) in extremely rapid succession. The human eye interprets the result as a single seamless image of higher definition.
    Wobulation eliminates the ‘screen door’ effect plasma and LCD displays are prone to. However, it must be applied carefully so that image sharpness is not reduced. HP have aspirations of using 4x wobulation for quadruple resolution both horizontally and vertically.
  • Dynamic Black DynamicBlack, also a trademark of Texas Instruments, is used in both models for the provision of deeper black levels with improved image detail in darker scenes. A contrast ratio of 12,000:1 is quoted.
  • Motion Adaptive Deinterlacing Both HP models also incorporate Motion Adaptive Deinterlacing which detects and compensates for motion in pictures, reducing any contouring and visual noise without affecting picture detail.
  • True-to-Life-Color True-to-Life Color is a technology aimed at producing accurate color temperature and warm, natural tones.
HP MD5880 Rear Projection TV

Rainbow Effect

Manufacturers of single-chip DLP displays attempt to minimize any “rainbow effect” by using, fast rotational speed, multi-segment color wheels. In this case HP have opted for a seven-segment color wheel. Before making a decision, potential purchasers of single-chip DLP rear or front projection products should always arrange a viewing as although big strides have been made in reducing the incidence of “rainbow effects”, sensitivity varies from person to person.

Both the HP models use a projection lamp cooled by an internal fan. The 150W UHP lamp is rated for a life of 6000 hours (to half brightness).

Thought has gone into good sound

To provide a better audio experience matching the visual one, HP’s MD6580 and MD5880 have audio provided by SRS Lab’s patented SRS TruSurround XT surround sound technology. For more information on the equipment supplied by SRS Labs can be found on their web site.

Connectors

An excellent, convenience feature of these two models is the location of the input/output jacks in an illuminated, recessed cavity at the front of the set, behind a large, drop down panel.

Both units have the following video connectors; 2 HDMI, 3 Antenna Input, 2 High Definition Component Input (Y, Pb, Pr), 3 Composite Video/ S-Video (3 total, either composite or S-Video) and Composite Video Out. Audio connectors include; 2 Stereo audio inputs, 1 Digital audio out and VGA. Those purchasers with an eye to the future will be pleased to know there is the capability to receive 1080p content through the component and HDMI inputs (at 24, 30, and 60 fps with HDMI). There are molded paths under the sets to give space for connected cables to be run in a tidy fashion.

Universal Remote

In an example of listening to customers, the remote control is a universal unit that can be used with other HP equipment including HP TV, HP Digital Entertainment Center, DVD player, cable box, satellite receiver, audio system, digital video recorder, VCR, or HP projector.

Warranty

Warranty on the MD6580 and MD5880 is a one-year limited warranty with in-home repair.

Samsung HP-S4273 - plasma TV - 42" review



This version of the Samsung HP-S4273 is a 42-inch, plasma television. Compared to other plasma TVs on the market, it is relatively inexpensive at around $1,865. In general, a liquid plasma display can recreate more realistic black-levels than an LCD display can.
Description: This version of the Samsung HP-S4273 is a 42-inch, plasma television. Compared to other plasma TVs on the market, it is relatively inexpensive at around $1,865. In general, a liquid plasma display can recreate more realistic black-levels than an LCD display can.

Pros: Has a 10000:1 contrast ratio, which is higher than some similarly priced TVs. Also, this TV has a side and rear connector location, which is somewhat more favorable than some similarly priced TVs. Furthermore, this TV supports Picture-In-Picture, though it requires a DVR or VCR to provide a second tuner. With built-in HDTV compatibility, this unit can display images that are significantly sharper and more realistic than regular television, as long as the source is high definition. (It can easily render standard-resolution digital TV broadcasts and also depict the full resolution of widescreen DVD video.) The 3:2 pulldown feature of this TV reduces artifacts that can occur when motion pictures are transferred to a digital format such as DVD.

Cons: None noted, given available product data.

Suitability: Made for those who are looking for a stylish, compact TV.

Value: Given its relatively inexpensive price, this TV has good features for the money.

Suggestions: (1) Be sure to shop for an HDTV receiver if you want to watch digital programming. (2) Since this TV supports progressive scan video, you probably will want to have a progressive scan DVD player connected to it. This will produce a relatively more "flicker-free" picture, compared to what is produced with conventional DVD players and TVs.

Color: Charcoal Black thin ribbon bezel


INTRODUCTION

This is the first 65" 1080p plasma to be produced. In fact, it is one of the first 1080p plasma monitors to be produced and plays an important part in the plasma vs. lcd struggle for supremacy in the flat panel TV market. Sharp has already produced and shipped a 65” LCD 1080p model (65D90U), and Panasonic has matched them with this screen, which is readily available and sells for a relatively strong price point. The 65PF9UK panel is produced at Panasonics’ new state of the art plasma factory outside of Osaka Japan. Panasonic also has a consumer version of the same 65” plasma model TH-65PX600U, which also sells without the table stand and speakers which are common to consumer products. The inputs of the two products are the main differences. The TH-65PX600U has HDMI input built in and a built in tuner, while the TH-65PF9UK has a built in RS232 port, a built in 15 pin VGA input for computer, a DVI port and optional input cards for HDMI or additional component or composite inputs.

PICTURE: 93/100

Whether using this very impressive plasma as a home theater centerpiece or as a public display for a fine garments store you will get very solid performance. I expected deviation in color and motion artifacts from this giant as opposed to its smaller relatives. Not the case at all. It performs in very much the same manner as the TH-42PH9UK. It has the same style of color rendition and white balance as the smaller Panasonic plasma products - though I did not experience the blacks as intense as they are on the smaller plasma products. This is a natural by-product of the larger screen and partially to be expected.

I tested the unit using a new Sony Blu-Ray player as well as a 1080p computer signal generator. My overall impressions were that the color was realistic and spectacular - not over saturated but still pronounced. The plasma displayed excellent dark scene detail which is a sticking point with most displays with a super high definition signal. While viewing our test 1080p DVD Black Hawk Down, we could clearly see the acne, sweat and cracks in Aidid’s and Sam Shepard’s faces during their face to face cigar smoking confrontation. The flesh tones were incredibly realistic. Emulating this type of performance with this much film-transferred dark scene material is a very tough test. In a couple of scenes some of the mesh camouflage netting behind a couple of the tents displayed some mapping and banding. I didn’t see it as an ongoing problem that existed however, rather an anomaly of those individual scenes.

After running a couple of test DVDs and signal generators to the plasma I ended up with the following settings as optimum and close enough to D6500K:

Panasonic Plasma TV Review
Picture (which is really contrast) - Set to 22
Brightness - Set to 8
Sharpness - Set to -14

The menu picture setting options for this plasma TV are standard, dynamic, cimema and supercinema. My adjustments were made from the standard option, but cinema option is also a good choice. The only bad option on this plasma (which is not set to overwhelm the showroom floor like consumer models) is the dynamic mode, which should only be used in extremely bright conditions. The dynamic mode naturally superficially enhances (by increases the sharpness control) edges and tweaks contrast while decreases brightness. The choice of these preset picture modes will depend greatly on the surrounding lighting in the viewing room as well as the signal being input. For HD signals you will not need as much contrast to see detail and depth in the picture. With lower end signals you may to use a slightly increased contrast setting such as with super cinema mode.

Individual color settings are surprisingly not accessible through the standard menu.

The just aspect ratio mode did an excellent job with algorithmically “stretching” a 4:3 picture for pleasing viewing on the 16:9 screen.

OTHER CONSIDERATIONS: 87/100

The aesthetics of the TH-65PF9UK is a high point for me. I like the simple non-obtrusive design of the inch and a quarter bezel in charcoal black. It doesn’t take away from the picture image. The unit is also super thin for such a huge screen, at only 3.9 inches in depth.

The menu is very easy to navigate and the unit has plenty of preset picture settings as mentioned above as well as plenty of aspect ratio settings which include the aforementioned Just mode. The remote is extremely plain; simple but with adequate functionality (no backlighting or anything fancy on the professional line). If you are using this plasma has a home theater TV, chances are you will have a universal remote to cover this function. The one drawback in the menu options of course is the lack of color adjustments.

The picture settings which you choose can be set individually for each input, allowing for flexibility with your signal input.

This plasma monitor has optional accessory cards so for a little more money you can set the inputs exactly the way you want them (This can been seen as a drawback, because of the limited included inputs, or as a positive due to the option of purchasing and implementing the inputs however you want them.) The included inputs are one DVI, one composite, one VGA 15 pin, one RS232 port, and one BNC component video input.

This plasma has the ability to show PIP or side by side picture from different inputs - so practically the user can answer e-mail on one side of the screen while watching a ball game on the other.

Lastly, this plasma is sold without a table top stand or speakers.

VALUE: 90/100

Surprisingly, I believe this unit is a good value at around $8000. I expected glitches in the picture performance for such a large screen and a first generation 1080p plasma. Instead, what I saw was rock solid performance. Sure, there are a few shortcomings like the lack of a color adjustment and limited (but flexible) inputs. The only competitor in the 65” 1080p market is the Sharp LC-65D90U, which sells for a couple thousand more dollars, so there isn’t much competition in this size range for 1080p.


OVERALL RATING (WITH PICTURE DOUBLE-WEIGHTED): 90.75/100*

Panasonic TH-50PH9UK Review

Excellent

8.0

out of 10
The good: Relatively inexpensive; excellent black-level performance; accurate color decoding; solid video processing with 2:3 pull-down; independent memory per input; versatile PIP function; extensive picture adjustments; customizable inputs.

The bad: Inaccurate primary colors; does not include a stand, a tuner, or speakers; limited to only four total inputs and doesn't include a digital input out of the box; cannot change aspect ratios with HDTV sources.

The bottom line: Although its features can't compete against typical consumer plasmas, the "professional" Panasonic TH-50PH9UK's excellent picture quality and price make it the best value at this size, bar none.


(pictured above) around $150, and Panasonic's latest line of professional plasma panels, the TH-PH9UK series, continues to turn everyday TV shoppers' heads for some very compelling reasons. While designed primarily for professional use, the picture quality of these TVs is better than that of most consumer models, and their prices are extremely competitive. The trade-off? Panasonic's pro plasmas come with just a couple of inputs, no speakers, and no stand, although you can purchase them separately. The HDMI input--a necessity in today's world--will cost you at least an extra $110, the standthe speakers, if you choose to add them, about $250. (The full list of accessories can be found here.) If the customization and extra accessories sounds like a chore, then the professional models probably aren't right for you.

If you can handle their limitations, however, the pro models still represent a fantastic value. The 50-inch TH-50PH9UK reviewed here follows in the footsteps of last year's TH-50PHD8UK with essentially the same feature set, although it does offer at least one significant improvement in picture performance. And while the Panasonic TH-50PH9UK didn't perform quite as well as the Pioneer PDP-5070HD, which earned our 2006 Editors' Choice award among the 50-inch plasmas we've tested, it costs significantly less and still produces a superb picture.

Design of Panasonic TH-50PH9UK

As you might expect from a product aimed toward the professional market, the Panasonic TH-50PH9UK is quite simple with no industrial design flare whatsoever. It is finished in a very dark gray, and other than the Panasonic name below the center of the screen and the power light all the way to the left, there is nothing else to distinguish it. The all-screen look results in relatively tiny overall dimensions for a 50-inch plasma: 47.6 by 28.5 by 3.7 inches WHD for the panel itself, with a weight of 81.6 pounds.

As we mentioned, stereo speakers are an optional accessory. You must also opt for either the table-top stand or the wall-mount kit to support the panel.

The remote is intelligently designed and as a result, very easy to use. We especially appreciated the separate keys for each input slot. Unfortunately, the clicker is not backlit at all and cannot control other devices. Internally, the menu system hasn't changed on the industrial models for many years and remains extremely simple and easy to navigate.

Features of Panasonic TH-50PH9UK

With a native resolution of 1,366x768, the Panasonic TH-50PH9UK matches the pixel count of just about every other 50-inch plasma on the market. It has enough pixels to display every detail of 720p sources; and all sources, from standard TV to DVD, to HDTV, to computers, are scaled to fit the native resolution.

As you may have surmised, the TH-50PH9UK doesn't offer much in the way of a feature package. Interestingly, it does have a PIP feature, which allows you to watch any two sources simultaneously, but that's about all she wrote for conveniences. There's no tuner, ATSC or otherwise, so to watch standard or high-def TV, you'll need to connect an external source, such as a cable or satellite box. Likewise, the lack of speakers means you'll need to connect your A/V sources to an external audio system or buy Panasonic's optional speakers to hear anything.

We were annoyed that the TH-50PH9UK still can't switch aspect ratios with HD sources, which is an issue if you're watching high-def on a channel that's sized improperly--like a lot of TNT channels--and your cable or satellite box can't change aspects. There are four aspect-ratio choices available for high-def sources.

The Panasonic TH-50PH9UK does have several picture enhancing features worth mentioning. First off, 2:3 pull-down is available in the video processing but must be engaged for all inputs individually in the setup menu, as the default setting is Off. Selectable color temperatures are on tap and include Warm (the closest to the broadcast standard of 6,500K), Normal, and Cool. Panasonic also gives you three Picture mode choices: Dynamic, Standard, and Cinema. The TH-50PH9UK has independent memory per input; this means you can use any mode you wish at any input and still be able to make changes to the picture controls (with the consumer models such as the TH-50PX60U, you must assign a picture mode to an input in order to set it up independently of other inputs). Finally, in the advanced menu, there are fine-tuneable grayscale controls and selectable gamma settings.

Connection options are definitely limited compared to other HDTVs on the market. The panel comes with one component-video input that is also configurable to RGBHV (for computers or other RGB gear); an S-Video input; a composite video input; a 15-pin VGA input for computers (1,366x768 maximum resolution) that can also serve as a second component-video input with the addition of an inexpensive adapter; and an RS-232 control port. It's also worth noting that the component- and composite-video ports don't use standard RCA-style connectors. You'll have to buy inexpensive adapters, available at any RadioShack, to turn the BNC-style jacks into RCA jacks that will fit most A/V gear.

The good news is that the TH-50PH9UK has hot-swappable inputs housed on removable boards. The set comes with two boards preinstalled--the component-video input on one and the composite and S-Video inputs on another (the VGA input is fixed). There is also an empty bay for adding a board your choice. We strongly recommend purchasing the optional HDMI board mentioned above for this slot. You can also remove existing slots and change them to suit your system's needs. Also, note that although there are only four total slots, you can connect more gear by utilizing an HDMI- or component-video switching device, such as some A/V receivers.

Performance of Panasonic TH-50PH9UK

In terms of reference-quality picture performance, the Panasonic industrial models, which have been among our favorites for several years, have recently been eclipsed by the latest generation of Pioneer panels. (See our review of the Pioneer PDP-5070HD for details.) That is because Pioneer has finally made its black-level performance competitive with the best Panasonic models, if not quite equal to them, while delivering more accurate primary colors, which means overall color accuracy is better on the Pioneers. With that said, you will pay a premium for the Pioneer over the Panasonic. Therefore, the TH-50PH9UK does represent the absolute best value-to-performance ratio in its size and category.

We began our evaluation of the Panasonic TH-50PH9UK by calibrating it for a darkened room using the Toshiba HD-A1 HD-DVD player as the primary source. Even before calibration, the TH-50PH9UK exhibited really good out-of-the-box performance compared to that of most other 50-inch plasma panels (see the geek box, below). If you check out the box, you'll notice that the Kelvin numbers are a little closer prior to grayscale calibration; however, the post calibration is actually more accurate and produces the better picture. The reason for this is that you can be very close to 6,500K and be significantly plus or minus green in the grayscale. In the calibration process, we fixed the plus-green problem, and the Kelvin numbers got a little bit worse. To see all of the final picture settings we used, click the Tips & Tricks tab at the top of the page.

As we have come to expect from the Panasonic industrial models, the color decoding was extremely acurate with no red push whatsoever. This resulted in excellent color saturation. Gamma and grayscale tracking were pretty decent, which resulted in solid overall color reproduction and exceptionally natural-looking skin tones. The Panasonic's weakness comes in the area of primary color accuracy. Red is reasonably close to the ATSC standard, but green is way off and heavily pushed toward yellow, making grass and trees, for example, look unrealistic.

Black-level performance remains among the Panasonic's main strengths. In fact, it could be argued that the TH-50PH9UK is better at black than any other panel on the market. Opening scenes from the HD-DVD version of Unforgiven were rendered perfectly with every bit of shadow detail visible, as well as blacks that were truly inky in nature. Thanks to the excellent blacks, the brighter scenes in the movie also had a real snap or pop to them, indicating an excellent contrast ratio, largely due to black level performance. Chapter four of Training Day, also on HD-DVD, was razor sharp, with even the most subtle details clearly visible.

Panasonic also made one big improvement with the 9UK series: it fixed the floating black problem of the previous 8UK generation, earning a passing grade in the black-level retention test in the geek box. The darkness of black areas is now constant and doesn't change depending on how bright or dark the picture content is, which helps improve details in shadows.
