The top chart shows the Home 10+'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 medium color-temperature mode and the theater black "color mode" (a misnomer, as it's mostly an iris), measures somewhat warm with dark images and comes close to 6,500 kelvin with brighter images. No gray-scale adjustments were accessible or possible.

This chart shows the gray scale (or color temperature) relative to the color points of the display's red, green, and blue liquid-crystal panels. All are somewhat off those specified by SMPTE. Green and red are both slightly yellow, while blue is slightly oversaturated and purple.

Using a full-field 100-IRE white (11.6 foot-lamberts) and a full-field 0-IRE black (0.015 ft-L), the contrast ratio was 773:1. Using a 16-box checkerboard pattern (ANSI contrast), the contrast ratio was 249:1. The best contrast ratio was achieved in the theater black setting. The brightest image was achieved in the dynamic setting and produced approximately 16 ft-L with a 100-IRE window (on an 87-inch-wide, 1.0-gain Da-Lite Da-Mat screen). Because the color temperature can't be fine-tuned, the latter number was achieved with a far-from-accurate color temperature.—GM
