5. Change Windows Settings
Windows allows you to manually adjust the display scale according to your monitor. However, certain games may encounter issues entering full screen mode if the display scale is set to a higher number than the recommended value for the game.

6. Update the Graphics Driver
If full screen still keeps minimizing or the game fails to enter full screen mode at all, you can try updating the graphics driver. An outdated or corrupt graphics driver can cause scaling or resizing issues on your computer.
So, visit your graphics card manufacturer’s website (NVIDIA, AMD, or Intel) and download available updates for your graphics driver. Alternatively, you can use the Device Manager to download the update. Here’s how:
Step 1: Press the Windows + X keyboard shortcut to open the Power User menu and choose Device Manager from the list.

Step 2: Double-click on the Display adapters.

Step 3: Right-click on your graphics driver and select Update driver.
