Maxent MX-26X3 LCD HD Monitor HT Labs Measures
Full-On/Full-Off Contrast Ratio—760:1;
ANSI Contrast Ratio—725:1
Measured Resolution with the Leader LT-446:
480: 480 (per picture height)
720p: 590 (pph)
1080i: Out to the limits
DC Restoration (poor, average, good, excellent): Excellent
Color Decoder (poor, average, good, excellent): Good
Measured Color Points:
Red Color Point: x=0.642, y=0.342
Green Color Point: x=0.269, y=0.615
Blue Color Point: x=0.146, y=0.055
The left chart shows the MX-26X3'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 warm color-temperature mode, measures cool with dark images and warmer but still rather cool with brighter images. After making adjustments using the Photo Research PR-650, the gray scale measures better, within 154 Kelvin of D6500, the accurate color temperature, across most of the range. It still peaks at the very bottom end at 518 degrees Kelvin over 6500K.
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 somewhat off those specified by SMPTE. Red is slightly reddish-orange, green is slightly oversaturated and somewhat bluish-green. Blue is slightly oversaturated and very slightly purplish-blue.
After calibration and using a full-field 100-IRE white (128.5 foot-lamberts) and a full-field 0-IRE black (0.169 ft-L), the contrast ratio was 760:1. Using a 16-box checkerboard pattern (ANSI contrast), the contrast ratio was 725:1.—GM
