irst, adjust brightness to 50 % position and contrast to100% position, and then generate "M

1280 x 1024 / 85Hz or 1600 x 1200 / 85Hz timings to cover entire picture area (picture size is shown in sect. 4.5).

haracters should be clearly identified at the center and all corners.

Brightness uniformity
With an active full area white video input pattern and contrast setting to 100%, no portion of the pattern shall be
less than 75 % of the luminance measured at the
