HDMI - how to force RGB Full Color range
I have problem to force HDMI output of graphics card GeForce GT 240 to work in
Full Color range mode (0-255) with DLP Benq MX660 projector. It always display image with white as a light gray, and black as a dark grey.
I have X server configured with two separate X screens.
Screen 0 is connected thrue VGA to smal 6" rgb display (800x600) and Screen 1 is connected thrue HDMI to the Benq MX660 dataprojector.
I have tried to force HDMI output to work in Full Color Range with option in Xorg "ColorRange" "Full" but it doesn't help. It always works in Color Range Limited Mode.
It will start working in Full Color range mode only if I disable using EDID information from
Benq projector (Option UseIDID "False").
But this isn't very nice way to do that.
Thanks for any help.
