Had this in full screen since I got my card (various games) but as it was in a new system and I wasn't into gaming I didn't bother, so today did a clean install , reset the bios only installed chipset drivers from the manufacturers site and tried subnautica, it seemed to run okay in full screen restarted a few times and it was still okay, installed devil may cry 5 and now get black screens in both games in full screen mode but fine in borderless or windowed mode. Nothing oc and I have run 3D mark & FurMark over and over with no errors, so any ideas ?
