APR: Automatic RGB Peak Regulation (APR) Threshold
The goal of the APR function (Automatic RGB peak regulation) is to compensate the
spread of contrast between sources or programs by regulating the peak amplitude of RGB
signals. This results in a picture with higher contrast whatever the input signal amplitude.
Besides, APR increases the contrasts of pictures with low contrast and avoids the clipping
at RGB output for pictures with high amplitude.
To enable APR, refer to OP3 in Option Bytes.
