Drive adjustment (3 x 8 bits)
In order to perform the “White balance” adjustment, the gain of the three RGB signals are adjustable
separately via the three Drive amplifiers (Registers 3, 4 and 5, I
The very large range of the Drives (48 dB) allows different standards or custom color temperatures.
It can also be used to adjust the output voltages at the optimum amplitude to drive the CRT drivers,
keeping the whole contrast control for the end-user only.
