Question / Help Black screen problem

[DaDiRa]

Hello everyone. A few days before I downloaded OBS and I have this problem:
When I preview the stream the game looks fine but when I actually start the stream the game turns black. It really works only with window mode.

Game capture must be used to capture fullscreen games, otherwise you must run the game with a windowed/borderless mode. Window capture and game capture are the best capture methods. If this is not your problem and you are on a laptop and still get black, that's a different issue
