It always launches games in fullscreen and whenever I alt tab to check discord or look something up, then my monitor goes black for a few seconds whenever I do that for some games, so is there a way that I can press F11 to fullscreen and unfullscreen? I have tried windowed and borderless mode, but that just makes it offcentered and it won't let me drag it. Any help would be greatly appreciated!
Use borderless fullscreen
Alt+enter
Seems like that black screen for a few seconds happens because games you play are set to a different refresh rate (not fps) from your monitor
This could be the issue but most games use the desktop refresh rate. Exceptions are games like Dark Souls or Elden Ring which limit their refresh rate to 60 (unless modded).
Lil bro haven't heard of borderless
No, not easily unless there's a fix I'm unaware of. Best solution is to use the steam overlay in game. Also, hitting Win+D will minimize all tabs, if you're okay with that.
Windowed + borderless gaming
