However, sometimes Windows 11’s brightness options go missing. If you cannot locate the brightness slider in the new Windows operating system, we have put together a list of 6 solutions that will help you get it back in no time.
Why Is the Brightness Slider Missing?
You might be experiencing the issue under consideration because of one of the following reasons:
In most cases, the TeamViewer application is the culprit behind the issue of the brightness slider missing on Windows 11. This happens when TeamViewer handles the drivers for your monitor, causing the brightness slider to disappear. The driver for your monitor may be outdated or disabled from Device Manager, making certain display features unavailable. Certain relevant Registry keys or GPE policies might be enabled.
Now that we know about the potential causes, let’s have a look at several effective troubleshooting steps that will help you fix the issue in no time.
1. Uninstall TeamViewer
If you have installed TeamViewer on your operating system, there is a good chance it might be causing the problem at hand. If this scenario is applicable, uninstalling the application can do the trick for you.
Here is what you need to do:
Type Control Panel in the search bar and click Open. Once you are inside the Control Panel, click on Uninstall a program under Programs. Your screen should now display a list of applications installed on your computer. From there, locate and right-click on TeamViewer. Select Uninstall from the context menu and wait for the process to complete. Once the TeamViewer is uninstalled successfully, go ahead and restart your computer.
Following a reboot, you should be able to see the brightness slider in Windows Settings.
2. Enable the Monitor’s Driver
If the monitor drivers are disabled on your Windows 11 machine, you are likely to face issues while using the relevant operating system features. The fix to this is simple, as all that you need to do is enable the driver back via Device Manager.
Follow these steps to do so:
Type Device Manager in the search area of your taskbar and hit Open. Inside the Device Manager window, expand the Monitors option. From the driver list displayed on your screen, right-click on your monitor driver and choose Enable device.
Once you have done that, you can proceed to check if the problem has been resolved.
3. Modify the Windows Registry
Windows Registry is an administrative-level utility that stores low-level information about the programs and processes of your operating system. There is a registry setting that, if enabled, can prevent you from adjusting the brightness of Windows.
You might be facing problems adjusting the brightness if an administrator or the operating system itself enabled that value. Here is how you can modify the settings to use the brightness slider:
Press Win + R keys on your keyboard to open a Run dialog box. Inside the text field of the dialog box, type regedit and hit Enter. Click Yes in the User Account Control prompt. Once you are inside the Registry Editor, navigate to the location mentioned below. HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System Locate and double-click on the NoDispCPL value in the right pane. Under Value data, type 0 and click OK. Finally, close the Registry Editor and restart your PC.
Hopefully, the issue will be resolved upon reboot.
4. Modify the Group Policy Editor
Group Policy is a Windows feature that controls the working environment of your operating system. The information about Windows programs and processes in this utility is stored as policies. Users can modify the operations of their operating systems by modifying the relevant policies.
You might also be unable to see the brightness slider if a policy named Disable the Display Control Panel is enabled in Group Policy Editor. You can verify this setting by accessing the Group Policy Editor as described below.
However, not that Group Policy Editor is not available on Windows 11 Home edition. If you are a Home edition user, jump to the next method below.
Press Windows + R keys on your keyboard to open a Run dialog box. Inside the text field of the dialog box, type gpedit. msc and hit Enter. Once you are inside the Group Policy Editor, navigate to the location mentioned below. User Configuration > Administrative Templates > Control Panel > Display Locate and double-click on Disable the Display Control Panel. In the next window, select Disabled. Click Apply and then hit OK. Finally, close the Group Policy Editor and restart your computer.
If the GPE policy was causing the issue under consideration, following the steps mentioned above should resolve it in no time.
5. Update Your Drivers
In addition to a disabled driver, the problem in question could also be caused by an outdated driver. Device drivers should always be updated in a timely fashion. This will not only help your computer run smoothly, but it will prevent it from developing costly problems in the future.
Many users reported that they managed to fix the issue by doing so, which is why we also highly recommend updating your drivers. This will not just help you fix the issue but also save your computer from expensive problems down the line.
6. Reinstall the Generic PnP Monitor Driver
It is also possible that your Generic PnP monitor driver on your computer is damaged or corrupted. If none of the solutions mentioned above worked for you, it could be a generic PnP monitor driver issue, in which case you should reinstall the driver while also removing the driver files from your system.
Here is how to do that:
Type Device Manager in the search area of your taskbar and hit Open. Inside the Device Manager window, expand the Monitors option. Right-click on your Generic PnP Manager driver and select Uninstall device from the context menu. Once done, click on the Scan for hardware changes icon located at the top as shown below. Wait for the scan to complete and then check if the problem is fixed.
