Anyone found a way to get full range color (0-255, not 16-235) on Nvidia cards, on WinXP, when using an HDMI output? The monitor is an HDTV which supports full range, and as far as I can see has a proper EDID.
I'm using the latest drivers from two weeks ago, v347.52, which should include the recently added a GUI option to select the color range, but I don't have it. I think the XP drivers are not showing all the options shown in Win6/7/8. (No, using Win7/8 isn't the solution I'm after. I also want to it to work under XP.)
The only way I can get full range is by using resolutions that show in the Nvidia Control Panel under "PC". But that doesn't help with 1920x1080x60, only possible under "Ultra HD, HD, SD" or "Custom", both of which have the broken color range.
I tried:
The Nvidia RGB Full range toggler, and it doesn't find the registry keys it normally sets.
Setting HKLM\SYSTEM\ControlSet001\Control\Class\{4d36e968-e325-11ce-bfc1-08002be10318}\0000\SetDefaultFullRGBRangeOnHDMI = 1 (actually, the subkey is 0003 in my case).
