This is only for nVidia users who are using HDMI on their display.If you're display supports Full RGB, which most do, you may notice you aren't getting the right colors and the blacks don't seem so black and the whites don't seem so white. This is because despite under Display->Adjust Desktop Color Settings your digital color format being set at RGB, its actually by default set at Limited RGB, not Full. And you will see there is no option for Full RGB. Don't use ycbcr444 as it will oversaturate reds and magentas.Full RGB is available only under Video->Adjust Video Color Settings, but this doesn't affect your games, applications, etc. Only videos.The trick to enable Full RGB for everything is a reg hack, and luckily you can use a tool to do instead. Find it here You must use this tool every time you install a new driver.Next, complain to nVidia to let this be a option in future drivers here:
