We all love to relax with a favorite game on our computers, but it seems that some users are having problems with fullscreen games and Windows 10.

This sounds like an unusual problem, and today we’ll try to fix that. Some users report that they are unable to run games in fullscreen mode.

According to them the game just switches to desktop and stays that way while game sounds play in the background.

Many users reported fullscreen issues while playing games, but they were able to solve the problem simply by disabling Teamviewer. After doing that, the issue should be resolved.

If disabling the Teamviewer doesn’t help, you might want to try uninstalling the application and check if that solves the problem.

6. Use the Compatibility mode

  1. Locate the problematic application, right-click it, and choose Properties from the menu.
