You may encounter the screen dimming while playing full-screen games due to improper monitor configuration (like Magic Bright etc.). Moreover, hindrance from a third-party application (like Bitdefender or Tobii Eye-Tracking) may also cause the issue at hand.
The issue is basically a dimmed screen while playing the full-screen games which makes games difficult (or in some cases, impossible to play).
Before proceeding with the solutions, check if reverting the Windows update (if the issue started after a Windows update) resolves the issue. Moreover, keep in mind that you may fail to resolve the issue on Windows 10 Education version (due to its limitations).
Following workarounds are reported by users to solve their issue, you may try if any of them works out for you.
- Simultaneously press Windows, Control, Shift, & B keys to restart the graphics driver.
- Check if disabling & enabling the graphics card in the Device Manager sorts the issue.

- You may unplug your charger from the system, launch the game, and plug back the charger to check if that resolves the issue.
- Check if disabling HDR solves the dimming issue.
- Check if disabling the Free Sync solves the issue.
