I haven't gamed for years, my brother built me a PC yesterday out of old bits - i5 2500k at 4.2ghz, GTX 970, SSD, 8Gb ram, Benq 27inch 144hz monitor.
I've downloaded Quake Champions and cannot for the life of me get it to run full screen. The game runs but the screen fades to black. I can press the windows key to minimize Quake and return to desktop, click quake (that's still running) to make it full screen again and I get to see everything running normally for about 2 - 3 seconds before it fades to black again. So Quake isn't crashing, it continues to run but the monitor just slowly fades out to black
I've done alot of googling and tried all sorts but I can't fix it. I can run QC in windowed mode but full screen just doesn't work.
I'd greatly appreciate any advice?
