Do the games you open on your computer not open in full-screen mode? While a keyboard shortcut can be the easiest solution, you may need to take a few more steps to figure out how to get your game to fill the screen.

Things You Should Know

First try pressing "Alt + Enter," then use the in-game menu to enter full-screen.
On a Mac, use the green button in the top left corner of the window or try a shortcut like "Command + Control + F" or "Fn + F."
If your game won't fill the screen, try some troubleshooting steps.
Change the Display Scale of your display since percentages greater than 100% may prevent your games from playing in Full-Screen Mode.
