It is not a good experience to play Windows 10 games in a not full screen mode. Windows 10 is still far from perfect and newly annoying "games not in full screen" issue crops up every day in varied Windows 10 builds, like Windows 10 Fall Creators Update, Anniversary Update, and more.
In this case, users have two black strips beside the gaming screen, which makes the games unplayable or disturbs users during their gaming.
Culprits to trigger the games not running in full screen mode are:
1. Improper graphics settings
2. Incorrect registry values
3. Display card driver problems
Generally, you can adjust the screen resolution of Windows 10 to the same resolution as the game. For example, if the game resolution is 1024* 768, then you need to change your Windows 10 display resolution to 1024* 768. But if this does not help to run the game in full screen, you can refer to the viable solutions below.
In this Windows 10 guide, we'll walk you through the top three ways to fix the games not in full screen mode after the latest Windows 10 updates.
