Full Screen Not Working

  • Full Screen isn't working anymore. It has been working perfectly fine, but today my game starts out in windowed mode. I try to apply Full Screen in the options menu (and I've tried ALT+Enter) and it just turns black, then my second monitor turns black for a second and my game minimizes, and the same thing happens when I click it while it's on my task bar.
    Also, when I downloaded the game the same thing happened, but I changed the resolution and it started working perfectly. But I haven't changed the resolution at all. The minimize thing has also happened with Goat Simulator and Batman: Arkham City. Any help would be appreciated.
  • Hello Gavindalf!

    Do you happen to have TeamViewer running on your system? I've seen something similar when running Overwatch with that software enabled.
