Hi Paul,
...However, even in 8-bit mode, having a
10-bit DAC is useful because it keeps the color lookup table curves from
introducing posterization through round-off errors.
If it's 8 bit data, you are feeding the DAC only 8 bits, if you are using a

Sure, but this is merely a software question really.
Once the software is in place, it behaves like hardware. Contrary to common

The video card includes a 256-entry lookup table (for each color) which gets
