Question Games not running in full screen

[Richard32]

My games dont go full screen if the resolution of the game does not match windows resolution. For example my windows resolution 1920x1080 and if i run a game at 1280x720 in full screen it only covers a part of the screen and the rest is black. (Check the attachment). I know its not a game problem because this is happening in all the games i have installed at the moment.

OS Name: Microsoft Windows 10 Pro
Version: 10.0.18362 Build 18362

Check the in-game resolution. If not, maybe compatibility mode will work?

The game perfectly fits to the screen if i am running it in the same resolution as my monitor. Tried compatibility mode, doesn't work. Also tried running the game after disabling full-screen optimizations.
