It is possible that the Windows 10 brightness slider does not work for several reasons. Often it's just a random bug or a problem that you can solve quite quickly. Or, it could be a problematic display driver giving you grief. Be that as it may, let's review these eight steps in resolving the problems that can definitively solve this problem.

1. Update Windows 10

The first thing to do before doing anything is to look for new Windows 10 updates. If the brightness slider does not work due to known issues with the operating system, especially after an update Microsoft is required to resolve them immediately.

If available, repeat the same for all additional adapters (dedicated or integrated) listed under the Graphics Cards section. Finally, try the brightness slider – it should work.

3. Update display driver

Obsolete display drivers are another reason why the brightness slider no longer works. While Windows 10 usually installs and manages the appropriate drivers for your graphics card, it is advisable to check.

Step 1: Open the device manager. Expand Graphics Cards, and then right-click your graphics card. In the menu that appears, click Update Driver.

Windows 10 will then check for updates. If new updates are found, it will install them automatically. Repeat this procedure for any additional adapters listed in.

4. Reinstall the display driver

Still having problems with the brightness slider? Then, it's time to reinstall the drivers for your graphics card. This should support corrupt files or badly cached driver data.

Step 1: Open the Device Manager, and then expand Graphics Cards. Then, right-click your graphics card, and then click Uninstall a device.

Check if the brightness slider is working. Otherwise, go to the next patch.

5. Update the drivers manually

Windows 10 may not automatically provide new drivers for your graphics card. If the brightness slider still does not work after the update or reinstallation, it is a good idea to manually download and install the latest drivers directly from the manufacturer's website. Use the links below to get the latest GPU / Display drivers from Intel, NVIDIA or AMD sites.

Point: To find the make and model of your graphics card, type "msinfo32" in the Start menu and press Enter. In the System Information window, expand Components, and then click View.

You can also use the hardware detection utilities provided by Intel, NVIDIA, and AMD to automatically download and install the latest updates.

6. Start troubleshooting the power

Improperly configured power settings also help to prevent the brightness slider from working properly. To verify if this is the case, consider using the troubleshooting tool built into Windows 10.

Start by typing troubleshoot settings in the Start menu. Click Open, and then scroll through the Troubleshooting window until you meet the power. Click it, and then click Run the Troubleshooter.

Follow the rest of the instructions on the screen, and you should have problems with the power management settings that are fixed at the end.

7. Enable Generic Monitor Drivers

Sometimes, some third-party programs may install replacement drivers for your primary display device. This can lead to conflicts with the basic features of Windows 10, such as the brightness slider. Therefore, returning to the default driver can help solve this problem.

To check if this is the case, go to Device Manager, and then expand Monitors. Right-click Generic PnP Monitor. If an option labeled Enable Device is listed in the pop-up menu, click it.

Then, exit Device Manager, and then restart your computer. Check if the brightness slider works without problems.

8. Use the Microsoft Basic graphics card

If the above fixes do not work, one last item can help you restore normal brightness slider operation. You must start using the Microsoft Basic Display Adapter, a generic driver that typically resolves compatibility issues related to the graphics card.

However, using this generic driver will restrict some features associated with your graphics card. You will likely experience performance issues and you may not be able to upgrade to higher resolutions. Keep this in mind.

Step 1: Open the Device Manager, and then expand Graphics Cards. Right-click your graphics card, and then click Update Driver.

Windows 10 will now start using the Microsoft base graphics card instead of the map-specific display drivers. You should find the brightness slider working without problems afterwards. This also proves that the problem lies with other display drivers. You must update or reinstall them correctly.

Note: Since using the Microsoft base graphics card will restrict the use of your graphics card, be on the lookout for new Windows updates, which could offer a permanent solution to the problem.

Shine brighter

So, did you manage to run the brightness slider on your computer? I hope you have corrected it immediately without going through any patches. Restarting your graphics card can really help correct this problem.

Not being able to use the brightness slider to control a display that is too bright or too dark can be terrible. While Microsoft is working to resolve this problem for good, remember to return to the above solution whenever you encounter this problem.

Then: Using safe mode in Windows 10 often gives better results when troubleshooting problems. Learn how to start your PC in Safe Mode easily.
