1. Use a Keyboard Shortcut to Enter Full Screen Mode

Using the Alt + Enter keyboard shortcut is the easiest way to enter full-screen mode in your games. This hotkey is compatible with nearly every game on Windows. Hence, it’s the first thing you should try.

Pressing Alt + Enter again will switch your game back to windowed mode .

2. Check the In-Game Display Settings

Most games include a dedicated display settings menu that lets you specify whether you want to run the game in full screen or windowed mode. You need to review this setting for your games to ensure that full screen mode is selected.

3. Disable Full Screen Optimizations in Windows

While the full screen optimizations on Windows are intended to improve your gaming experience, they can occasionally result in games not opening in full screen mode. If that’s the case, disabling full screen optimizations for your game should help.

1. Right-click on your game’s shortcut and select Properties.
2. Switch to the Compatibility tab.
3. Tick the Disable fullscreen optimizations checkbox.
4. Hit Apply followed by OK.
   

4. Set the Display Scale to 100%

Certain games may face difficulties entering full screen mode when the display scale on Windows is set higher than 100%. Setting the display scale at the recommended value can help ensure that the game is rendered at the native resolution of your monitor, without any scaling or resizing applied by Windows.

To change the display scale on Windows, open the Settings app and navigate to Display. Click the drop-down menu next to Scale to select 100%.

5. Use the Compatibility Mode

Another thing you can do is run your game in compatibility mode, especially if it’s an older game. Here’s how to do it.

1. Right-click on your game’s EXE file and select Properties.
2. Switch to the Compatibility tab.
3. Tick the Run this program in compatibility mode for checkbox.
4. Use the drop-down menu to select an older version of Windows, such as Windows 8 or Windows 7.
5. Click Apply followed by OK and then open your game again.
   

6. Disable Any Apps With Overlays

Occasionally, overlays from apps like Discord, Steam, or GeForce Experience can disrupt the full screen functionality of certain games, resulting in issues. To check for this possibility, you can temporarily disable the GeForce overlay , the Discord overlay, or any other software that shows overlays to see if this works.

7. Perform Some Basic Windows Fixes

If your games are still not opening in full screen at this point, you can try a couple of basic fixes and see if they work.

• Update Your Graphics Driver: Outdated or incompatible graphics driver on your PC can keep games from running in full screen mode at times. You can try updating the graphics driver on your Windows PC via Device Manager and see if that solves your problem.
• Run the Game as an Administrator: In some cases, running the game as an administrator can also help fix the problem. If this method proves effective, you can configure your game to always run as an administrator on Windows .

Experience Gaming Like Never Before With a Full Screen Advantage

Playing games like Valorant, FIFA, Battlefield, and others in windowed mode can greatly dampen your gaming experience. Hopefully, that’s no longer the case, and one of the above tips has gotten your games to open in full screen mode again.
