Windows 10: My games darken in fullscreen

Some games i play darken when in fullscreen or borderless window. I think this started happening when i opened NVIDIA control panel for the first time but i didn't change anything. I tried everything that i found on the internet updating my drivers, i checked the adaptive brightness setting and the power saving settings, i even did a factory reset. It is really bothering me as the games that do this are basicly unplayable without fullsreen.

My games go dark in fullscreen

As the title said my games significantly darken in fullscreen (almost like adptive brightness). But that is occurring only in about half of my games. And in most games with this problem it is fixable by switching those games to borderless window. But in two or three games this solution dosen't work. And playing windowed games is quite the pain. So am asking here as my last resort. I will be greatfull for any solutions as i really enjoyed these games.

 

When i click lmb while in any game is in fullscreen mode, the game app window disappears for a second and then reappears.

I've gathered some steps for you to try. Please feel free to skip any that you've already attempted. Let me know if any of these solutions help resolve the issue:

1. Update Graphics Drivers:
   
   Ensure that your graphics drivers are up to date. You can do this by visiting the website of your graphics card manufacturer (NVIDIA, AMD, or Intel) and downloading the latest drivers.
   
2. Disable Fullscreen Optimizations:
   
   • Right-click on the game executable or shortcut.
     
   • Select "Properties".
     
   • Go to the "Compatibility" tab.
     
   • Check the box for "Disable fullscreen optimizations".
     
   • Click "Apply" and then "OK".
     
3. Check for Background Apps:
   
   Some background applications might interfere with fullscreen games. Try closing unnecessary applications, especially those that might have overlay features (e.g., Discord, GeForce Experience, etc.).
   
4. Adjust Game Settings:
   
   Sometimes, changing the in-game display mode from fullscreen to borderless windowed mode can help resolve such issues. This can be found in the game's video or display settings.
   
5. Check for Windows Updates:
   
   • Go to "Settings" > "Windows Update" > "Check for updates".
     
6. Run the Game as Administrator:
   
   • Right-click on the game executable or shortcut.
     
   • Select "Run as administrator".
     
7. Disable Overlays:
   
   Overlays from applications like Steam, Discord, or NVIDIA GeForce Experience can sometimes cause issues. Try disabling these overlays to see if it resolves the problem.

Windows 10 1709 (16299.309) has somehow disabled 'Fullscreen' in games.

I recently updated to 1709 and have found that games no longer have access to fullscreen mode.

Most games force me directly to Windowed mode, and no longer list Fullscreen in the enum. Some games still allow windowed fullscreen. Games that list the standard Fullscreen typically crash or post an error when I swap to that mode.

The only thing that has changed on my system is my OS version, and I've been using an otherwise identical setup for gaming for years.

Since updating windows, I updated my video drivers, which resolved nothing. Sadly I just passed my 1 week window to undo the windows 'upgrade'.
