A couple of Guru's recently told me to put this on Nvidia settings but did not explain why. My monitor is calibrated correctly via the OSD. Gamma is correct as well as colours already. In Windows colour management there is a .icc that was created by me running the Windows 'Calibrate display' but the tick box 'Use my settings for this device' is not ticked. I did not actually change anything in the 'Calibrate display' wizard any way. So I have a few questions then. Do I tick that box and/or use the Nvidia setting also? Or do I just use the 'application controlled' in NV driver and/or click tick box in Windows colour management. To many combinations and I have no clue as to what is correct. Another thing is that 'Use Nvidia settings' does not stick when restarting the PC. Why would I use one or the other in NV panel? Thanks for clearing any of this up. It's been bugging me a while and other Guru's could benefit greatly from the answers! Thanks in advance, Sy.
