One day, my power went out. Now I am no longer able to choose the recommend resolution of my monitor (3840 x 2160). It instead maxes out at a resolution of 1920 x 1080. I have been able to get it back to normal after restarting and turning of my computer about 5 times. But after I turn my computer off then on again, it no longer lets me to use the 3840 x 2160 resolution. I do not wish to spend 20 minutes of my times tinkering with my computer just so I can do something on a good resolution. Any help would be greatly appreciated.
