Windows 10 Games' full screen problem (all games running in windowed mode)

Hi, recently I faced with a problem with my games on Windows 10 PC.

Approximately a month ago all of my games stopped to run in full screen mode. Instead of full screen mode I can see only windowed mode. All game settings are set to run games in full screen mode.

I've tried to reinstall the graphics adapter driver twice. It didn't help.

I tried to run games in compatibility mode (Windows 7 and 8), it didn't help either.

My PC specs:

- Windows 10 x64 with anniversary update 
- MSI GeForce GTX 1070 video card
- Intel Core I7 6700K CPU
- MSI GamingX G5 motherboard
- Kingston SSD drive 240 Gb

I have no idea what should I do to fix that problem as I spent a lot of time reading different posts on forums. BTW please don't suggest to try click Alt+Enter to enter full screen mode.

Does anyone know how this problem can be fixed?

Hi Nazarii,

We got your concern. We would like to know if this happens only in games? What are the games that won't run in full screen? Do you see any error message?

You can also do these basic troubleshooting steps:

Uninstalling display drivers.
1. Move the mouse to bottom left corner and right-click on the ‘Start icon’.
2. Select ‘device manager’.
3. Expand ‘Display adapter’ and right-click on ‘display adapter’ and select ‘uninstall’.
 
Installing display drivers in compatibility mode.
1. Download the display drivers from the manufacturer’s website.
2. Right-click on the driver and click on ‘properties’.
3. Click on the ‘compatibility’ tab and check the box ‘Run this program in compatibility mode for’ and select Windows 7 operating system from the drop down.
4. Click on ‘Apply’ and click ‘OK’ and run the file to install it.

Hi Richard. 

Yes, this problem can be reproduced only in games. And it appeared when one of the updates was installed. 

I don't see any error messages while starting the games. They just don't run in full screen...

Games which I have problem with:

- Far Cry 4

- FIFA 15

- Metro 2033 Redux

- and others...

Regarding the driver reinstallation: 

I've tried to reinstall the driver in compatibility mode but it didn't help either.

Thanks.

Richard, thank you for your help.

I've figured out what causes full screen issue. It's Teamviewer running service. If I stop it my games run normally in fullscreen mode.

I logged in to thank you. I've been trying to fix it for a month, searching Google for a solution, but without success. Now it was just disable TeamViewer 10 and all the games run in full screen.
