I built a new PC for Christmas. In the three months since then, I've had this problem occur 4-5 times. After letting my computer sit for a while, such that it turns off the display, and coming back, the image will appear distorted, as if there are two images that are a bit out of sync, creating a jagged, fuzzy appearance to my entire desktop.
The interesting thing is, if I start a game that is full screen, it will appear normal, but when I exit back to the desktop, it will still be fuzzy. All windowed applications appear fuzzy too.
I am running a Windows 7 fully updated OS, with an EVGA nVidia GTX 760 video card and an ASUS VG248QE 24" monitor that is connected via a displayport cable.
My questions are: what is the cause, can this be prevented, and how to fix it?
