Nvidia control panel gives me two resolutions to choose: One under the PC category 1920x1080 at 75hz, which looks better to me. However, the second option under Ultra HD gives 1920x1080 at 60hz, which is what i want, but whenever i select this resolution, the display seems more whiter than at 75hz. I really want to load up 60hz, but it makes the screen a little brighter and foggier than usual. Setting up custom resolution under PC category for 60hz quotes that i'm trying to make a duplicate resolution. I want to make the screen work at 60hz but the picture being like that at 75hz: more clearer. Any help would be appreciated.
