Windows 7 Pro 64-bit SP1 computer with AMD FirePro 2270 (Tried 4 sets of drivers from Dell and AMD). Works perfectly with all apps except QuickBooks 2014. Other profiles work perfectly with QuickBooks. The problem is opening and working within QB2014 the windows display resolution will change to 640x480. It may change back immediately or shortly after, but will keep reverting to 640x480. Changing the setting in Windows will work until you start using QB again. Intuit has removed, run the clean utility and reinstalled and still puzzled by the problem. I am going to try copying the profile and then recreating, and if need be try a clean profile and setup the user from scratch. Before that happens, I am hoping someone might be able to shed some light on this issue.
