Today I switched from Radeon HD 7870 to GeForce GTX660 SLI. For soem reason, when I'm using RGB everything has "light shade", so for example dark looks like gray and so on. Switching to YCbCr fixes it, but I want RGB. I didn't have this issue before. One more thing: somehow it got fix by changing some color settings in NV control panel, but reverted back the moment I ran BioShock Infinite. How could I fix this?
