Issue when changing to desktop gamma

I just wanted to point out a recent issue I ran into when messing around with my video settings. When I changed my gamma settings to desktop gamma settings, it caused me to get a black screen with game sound from then on and every time I launched the game after. If you run in to this issue all you need to do is go to your Config file and delete the bottom line that involves "Desktop Gamma". Not sure if this can be fixed but just wanted to make a post about how to fix it personally for yourself in case anyone else ran into the issue.
