Screen dimming is an issue that can arise on Windows 11 PCs. When screen dimming occurs, a monitor’s brightness level drops by varying degrees without any user input.

Screen dimming more commonly arises when users are playing games. Many have posted on forums about screen dimming automatically lowering brightness for Windows games. The screen dimming can make a lot of games too dark.

If screen dimming spoils your gaming as well, there are a few ways you might be able to fix it. Give the potential resolutions below a try.

What causes Windows 11’s screen dimming issue?

Screen dimming can arise because of certain Windows 11, or built-in monitor features that automatically lower brightness levels. The issue may also pertain to graphics drivers. These are some of the more common causes of screen dimming:

  • Night Light and Game Mode: Night Light and Game Mode are two other features in Windows 11 that can feasibly cause screen dimming when you’re playing games in full-screen mode
  • Monitors’ auto-dimming features: Some monitors have auto-dimming features that reduce brightness levels for Windows games
  • Graphics cards’ drivers: Your graphics card’s driver might be faulty or outdated
  • Adaptive brightness: Some laptops have adaptive brightness features that automatically lower the brightness level to extend battery life

However, you can always prevent your laptop screen from dimming.

Our solutions will come in handy if Windows 11 screen brightness keeps changing, Windows 11 adaptive brightness is missing, or your screen dims after 30 seconds.

Your monitor might have an auto-dimming feature that’s dimming the brightness. The best way to determine if that’s the case is to look through the manual for your PC’s VDU (visual display unit).

A driver updater utility like DriverFix will scan your PC and list devices with outmoded drivers. Then you can download and install new drivers with the software.

  5. Select the Disable all button.
  6. Click Apply to save the new boot settings, then press the OK button to exit MSConfig, and select Restart on the dialog box.

If this resolution fixes the screen dimming, a background process, service, or app was likely causing it. You’ll need to identify the background process, app, or service to resolve the issue if you want to restore your PC’s original boot configuration.

You can restore the original boot configuration by selecting the Load startup items option in MSConfig you previously disabled. Click the Enable all button in MSConfig to restore third-party services.

The resolutions above should be enough to fix screen dimming in Windows 11 for many users. Those potential fixes are especially recommended for screen dimming that arises when playing games.

If those aren’t enough to solve Windows 11’s screen dimming, there could be a hardware issue with your PC’s monitor. In this case, you might need to return and change the VDU (or the whole PC if it’s a laptop) to its manufacturer for repairs.
