How to fix Adaptive brightness not working in Windows?

Issue: Hi. Every time I watch a video or play games, my screen becomes much brighter than I originally set it to be. I am not sure why Adaptive brightness is not working correctly. Any tips?

Solved Answer

Adaptive Brightness is a useful feature in Windows that automatically adjusts the screen brightness based on the ambient lighting conditions. However, it can be frustrating when it stops working correctly, either failing to detect changes in the light environment or adjusting the brightness inappropriately.

One common cause of Adaptive Brightness not working correctly is a bad Windows Update. Microsoft regularly releases updates to Windows, and sometimes these updates can interfere with the functioning of Adaptive Brightness. If you suspect this is the case, try rolling back to a previous version of Windows or updating to the latest version.

Another possible cause of the problem is corrupt registry files. The registry is a critical component of the Windows operating system, and if its files become damaged or corrupted, it can cause issues with various system features, including Adaptive Brightness.

Issues with the graphics driver can also cause problems with Adaptive Brightness. If the driver is outdated, incompatible, or corrupted, it can prevent the system from detecting changes in the light environment correctly. Updating or reinstalling the graphics driver is usually the solution to this problem.

Finally, incorrect power plan settings can cause Adaptive Brightness to malfunction. Windows offers various power plans that control how the system manages energy consumption. If the power plan settings are incorrect, it can cause the system to override the Adaptive Brightness feature. Adjusting the power plan settings or creating a new power plan that is optimized for the environment can often solve this issue.

Below we provide several tips that should help you fix Adaptive brightness not working correctly in Windows. We also recommend running a scan with powerful PC repair software FortectMac Washing Machine X9, which can quickly and easily repair damaged system files, ultimately fixing any issues that come with it.
