1111 1111 = 255 (bright)

1000 0000 = 128 (default)

0000 0000 = 0 (dark)

The output black level relative to the nominal black level (16 out of 256) as a function of the

Brightness[7:0] setting and the Contrast[7:0] setting is as follows:

Black Level = nominal_black_level + (Brightness[7:0] – 128) + (438 / 4) × (1 - Contrast[7:0] / 128)
