I am running 4k AOC screen which should run at 60Hz ! Before upgrade was ok but now refresh rate is 30Hz and I cannot change it. Gaming is now very lumpy. Need to have correct refresh rate set.
Any help would be appreciated.
How do you get a tv that has a 240Hz refresh rate to use it? Every thing that comes out of my cable box is at 60Hz and blu-ray player is 24Hz. How does this work?
