NuVision NVX32HDU LCD HD Monitor HT Labs Measures

HT Labs Measures: NuVision NVX32HDU LCD HD Monitor

Full-On/Full-Off Contrast Ratio—604:1; ANSI Contrast Ratio 586:1

Measured Resolution with the Leader LT-446:
480: 480 (per picture height)
720p/1080i: Out to the limits of the 1366 by 768 panel

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

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

Measured Color Points:
Red Color Point: x=0.638, y=0.339
Green Color Point: x=0.266, y=0.603
Blue Color Point: x=0.145, y=0.066

The left chart shows the NVX32HDU'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 measures slightly cool across the gray scale. After making adjustments using the Photo Research PR-650, the gray scale measures within 377 degrees Kelvin of D6500, the accurate color temperature, across the entire range. Although the darkest images measured 6,500 degrees Kelvin, the actual x,y coordinates were lacking green.

The right 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 slightly off those specified by SMPTE. Blue is slightly oversaturated, red is slightly reddish-orange, and green is fairly bluish-green.

Using a full-field 100-IRE white (85.77 foot-lamberts) and a full-field 0-IRE black (0.142 ft-L), the contrast ratio was 604:1. Using a 16-box checkerboard pattern (ANSI contrast), the contrast ratio was 586:1. The best contrast ratio was achieved in the Backlight 2 setting. The brightest image was achieved in the Backlight 1 setting and produced 118.2 ft-L on a 100-IRE window. Black level in this mode was 0.197 ft-L, which is a contrast ratio of 600:1—GM
