Auto brightness settings location?

I’ve poured over ever inch on where I think these settings can be . I’m sick of halfway through a game and the screen just goes black . Like so dark I. Can’t see anything . I restart the computer and it’s normally fine . Sometimes it dosnt fix itself . Why the hell dose the happen and how do I make it stop

Would also help if fallout 76 the game in trying to play , had actually fucking display settings. There’s no brightness what so ever . You want to change one small graphic detail then you best be ready to restart your entire game . I’m sick of this

Are you sure your computer isn't going to sleep? You can change that in the Power & Sleep settings tab.
