5 Easy Ways to Fix Brightness not Working in Windows 11– As most of you know, Windows 11 has been out for quite some time now, and if you’re anything like me, you hate it. 

I know I do! One of the things that annoy me the most about Windows 11 is the fact that my computer keeps getting brighter or dimmer without my consent. 

Not only does this happen at random but it also makes it impossible to concentrate on any specific task as I try to fix my brightness not working in Windows 11 and get back to work.

5 Easy Ways to Fix Brightness not Working in Windows 11

Check your power settings to Fix Brightness not Working in Windows 11

It turns out that one of the causes of this issue is your power settings. This can cause a problem because it will seem like your brightness settings are not working when, in reality, they are just being overridden by your power options. 

To fix this problem all you have to do is go to Settings -> System -> Power & Sleep and then make sure the Dim the display option is unchecked.

Another common cause for this issue is that there’s a third-party app installed on your computer that’s overriding or disabling your brightness settings.

So if you’ve been installing or uninstalling apps lately, then make sure you check for any apps that might be interfering with how bright or dark your screen gets.

Adjust your screen brightness manually

If you’re having trouble with your brightness not working, there are some things you can try. The first thing to do is manually adjust your screen brightness by right-clicking on your desktop and then clicking Display Settings. 

Scroll down to Adjust Screen Brightness, where you’ll find a slider that will let you adjust the brightness level. 

You can also click on the up or down arrows next to it, which will allow you to change it by a percentage point. If this doesn’t work, try changing your monitor settings or connecting an external monitor and see if that fixes it. 

You may also want to restart your computer or update your graphics card drivers. If none of these methods work for you, consult with a professional for help troubleshooting this issue.

Modify your registry settings

Open the registry editor. Navigate to HKEY_LOCAL_MACHINE > SOFTWARE > Microsoft > Windows NT > CurrentVersion > SystemProfile. 

In the right-hand pane, search for a value named PowerSettingOverride, and double-click it. Change its data from 2 to 1, and click OK. In the left-hand pane, search for a value named Scaling heuristic, and double-click it. 

Change its data from 0 to 1, and click OK. Restart your computer and check if this solves your problem with brightness not working correctly on your laptop or desktop computer running Windows 11.

Enable adaptive brightness

A clean boot is a troubleshooting technique that helps determine which software might be causing problems. This removes all software running on your computer and starts it up again, so you can see if any of these programs is interfering with brightness. 

To do a clean boot, you need to follow these steps:

  1. Press the Windows key + R on your keyboard.
  2. Type msconfig and hit enter.
  3. Click on the General tab.
  4. Click Selective Startup, uncheck it and then click OK.
  5. Click on the Services tab, check the Hide all Microsoft services box, and then click Disable all.

Change your display mode

If you find that your brightness buttons are not working in Windows 11, it could be because your display mode is set incorrectly. To fix this issue:

1. Open the Settings app and click on System. 

2. Click on Display at the bottom of the left-hand column and then choose Advanced display settings from the right-hand column. 

3. You should see a new window with a list of display modes at the top, with an option to change your current one next to it. 

Click on your current one (probably Automatic) and select Manual instead, which will allow you more control over how bright or dark your screen is (including any other custom settings you want). 

4. Exit the Settings menu by clicking on the X in the upper-right corner and test your brightness controls again. Hopefully, they work now!

5. If they still don’t work, try rebooting your computer, restarting Windows 10, or updating all of your graphics drivers first as these can sometimes cause issues with controlling screen brightness too!

Connect to an external display

The quickest way to fix brightness issues is by connecting a second monitor. That way, you can control the brightness on the second monitor and leave your primary monitor at its current settings. 

If you don’t have an extra display, or if connecting a second display doesn’t solve your problem, try these steps:

1. In the Action Center notification area of your taskbar, click the Settings icon (it looks like a gear). 

2. Click System > Display > Change brightness and move the slider up or down until it’s where you want it. You’ll need to log out of your account for this change to take effect. 

3. Open Device Manager and look for Intel(R) Graphics Media Accelerator. Right-click the driver, select Update Driver Software, then follow the prompts. 

4. Restart your computer in Safe Mode. Open Device Manager again, find Intel(R) Graphics Media Accelerator, right-click it and select Uninstall device from list. 

5. After rebooting in Normal Mode once more, go back into Device Manager again to see that Intel(R) Graphics Media Accelerator has been restored automatically with new updated drivers installed.
