I'm sorry, I have no idea. The most I can do is to copy and paste the option description from the Nvidia Linux driver readme: --- cut --- Option "Dac8Bit" "boolean" Most Quadro products by default use a 10-bit color look-up table (LUT); setting this option to TRUE forces these GPUs to use an 8-bit (LUT). Default: a 10-bit LUT is used, when available. --- cut --- > I'll try and go one better by fixing it so that it should work with a 10 > bit frame buffer and 1024 VideoLUT entries. Hard for me to test though ... Of course I'm at your disposal for testing, just send me an email when you need.
