The output black level relative to the nominal black level (64 out of 1024) as a function of the Brightness[7:0] setting is as follows:
Black Level = nominal_black_level + (MB + 1) × (Brightness[7:0] - 128)
Where MB is the brightness multiplier setting in the Brightness and Contrast Range Extender register at I
