HT Labs Measures

Contrast & Resolution

Peak white level: 24.0fL
Black level: 0.035fL
Peak contrast ratio: 686:1

This is pretty poor for a peak-contrast result. Ideal peak white level in dark room is 16fL; a larger image would bring peak white and black level down, which would be a good thing, but it probably wouldn't help the contrast ratio.

Color Accuracy & Grayscale

The color points were fairly close to where they're supposed to be; green, yellow, and red were a bit oversaturated, but not bad.

There was too much blue in the color balance before calibration.

After calibration, the color balance was almost perfect across the entire brightness range.
