So, I was trying to set my computer on 60hz, on screen resolution box, and It says on advance settings-> monitor, under that it says: screen resolution refresh , something like that, and I was hoping to change that into 60hz, but it only says that it can be still at: use hardware default settings.. This is problem with my screen, because when I startup my PC it shows a little box, and It says:Not optimum mode, 1360x768 60hz". GUYS PLZ HELP ME E!
