So I was at my friend's house he was having a problem with his PC and he was using PC at low resolution so I increase the resolution at full and first it gave black screen than it displays "this video mode is not supported" or something like this I try restarting the PC and pressing F8 at boot at boot It didn't work. Now he can't even use his PC because of me. I very sad about it. If someone knows how to reset resolution in Windows 8 or solve this problem, kindly answer.
