HT Labs Measures: HP SLC3760N LCD HDTV

Full-On/Full-Off Contrast Ratio—1,068:1; ANSI Contrast Ratio—967:1

Measured Resolution with the Leader LT-446:
480: 480 (per picture height)
720p: 720 (pph)
1080i: Out to the limits of the 1,366-by-768 panel

DC Restoration (poor, average, good, excellent): Excellent

Color Decoder (poor, average, good, excellent): Excellent

Measured Color Points:
Red Color Point: x=0.634, y=0.334
Green Color Point: x=0.273, y=0.600
Blue Color Point: x=0.146, y=0.066

The top chart shows the SLC3760N's gray scale relative to its color temperature at various levels of intensity, or brightness (20 IRE is dark gray; 100 IRE is bright white). The gray scale as set by the factory, in the Mid-Low color-temperature mode and the User picture mode, measures very cool with the darkest images and very warm with just slightly brighter images. The rest of the gray scale is somewhat cool.

The bottom chart shows the gray scale (or color temperature) relative to the color points of the display's red, green, and blue color filters. These are somewhat off those specified by SMPTE. Red is very slightly undersaturated and very slightly reddish-orange. Blue is very slightly greenish-blue. Green is rather bluish-green.

Using a full-field 100-IRE white (89.7 foot-lamberts) and a full-field 0-IRE black (0.084 ft-L), the contrast ratio was 1,068:1. Using a 16-box checkerboard pattern (ANSI contrast), the contrast ratio was 967:1. The best contrast ratio was achieved with the backlight in the STD setting. The brightest image was achieved with the backlight in the +16 setting, which produced 151.2 ft-L with a 100-IRE field and 0.143 on a 0-IRE black (1,057:1). The best black level was achieved with the backlight in the –16 setting. In this mode, the SLC3760N had a light output of 29.41 ft-L and a black level of 0.028 ft-L, making for a contrast ratio of 1,050:1.—GM
