cannot display this video mode, change computer display input to 1920x1080@60Hz
I was playing around with my monitors refresh rate and I set the refresh rate to 30hz to see what happened, and to my surprise, the screen displayed,'cannot display this video mode, change computer display input to 1920x1080@60Hz.' Ive tried everything to change it back to 60hz and nothing has happened. I have a Phillips monitor.
someone please help!!!!
