My Steam game won't run in fullscreen mode. How do I fix it?

If your Steam game is having trouble running in fullscreen mode, you can try a few troubleshooting steps to resolve the problem.

• Consider using the Alt + Enter keyboard shortcut to switch between fullscreen and windowed mode in most Windows games. Pressing Alt + Enter should take your game into fullscreen mode, and pressing the same keys again will return it to windowed mode.

• Look in the game's options or settings menu for a specific fullscreen mode toggle. This option is typically found in sections labeled " display," video, "game," or "graphics." If you cannot find a fullscreen option, try pressing the F11 key instead. Keep in mind that pressing F11 may result in stretched or pixelated graphics, or the game may not fit properly on your screen.

• You can also try changing the resolution in the game's settings to see if that resolves the fullscreen issue. Try different resolutions, including your native screen resolution, to see if anyone setting improves the problem.

• Some games provide a borderless windowed mode that closely resembles fullscreen but is not true fullscreen. If your game has this option enabled, try turning it off to see if it helps.
