I have a Radeon Pro X1600 and set the resolution to 1280x1024. Works Fine. When I set it to 1600 x 1200 the screen goes all black and cannot get back to options to change this. This includes uninstalling the application and then reinstall. THe program unistall is not deleting the registry values i guess. Can you give me a manual uninstall for the screen resolution . It has been frustrating.
