4.8.4. Brightness and Contrast Adjustment
The monitor is factory calibrated. For DVI-D input we suggest don’t change the contrast
value, any change of this will change the optimized LUT settings and will lose some of the
image information. We suggest to only adjust the backlight of the monitor if the luminance
is not acceptable.
