Fix Windows 10 brightness control not working

Are you experiencing issues with your Windows 10 brightness control not working?

Check for driver updates: Make sure your graphics card drivers are up to date, as outdated drivers can prevent the ability to adjust brightness.

Understanding the Brightness Issue

If you are experiencing issues with the brightness control on your Windows 10 PC, there are a few things you can try to fix it.

First, make sure that your device drivers are up to date. You can do this by right-clicking on the Start button, selecting Device Manager, and then updating the drivers for your display adapter.

If that doesn’t work, you can try adjusting the brightness using the Fn key on your laptop keyboard. This key is usually located near the bottom left of the keyboard and has a sun icon on it.

Another thing to check is whether there are any updates available for your operating system. You can do this by going to Settings > Update & Security > Windows Update and checking for any available updates.

If none of these solutions work, you may need to check for any malware or software bugs that could be causing the issue. Running a full system scan using your preferred antivirus software can help to identify and remove any potential threats.

If all else fails, you can reach out to customer support for your device or visit the manufacturer’s website for more specific troubleshooting steps.

  • Click Save changes to apply the new brightness settings

Utilizing Graphics Card Software and Adaptive Brightness

To fix Windows 10 brightness control not working, you can utilize your graphics card software and adaptive brightness settings. First, ensure that your graphics card drivers are up to date. Go to the manufacturer’s website, such as Nvidia or AMD, and download the latest drivers for your specific graphics card model. Install the drivers and restart your computer.

Next, check your adaptive brightness settings. Go to the Control Panel and select Power Options. Click on “Change plan settings” for your current power plan, then select “Change advanced power settings.” Look for the “Display” option and expand it. Make sure that adaptive brightness is enabled. If it is already enabled, try disabling it and then re-enabling it to see if that resolves the issue.

If you are using a laptop, you may also need to check the settings for the function key that controls brightness. Look for a dedicated brightness key on your keyboard, usually indicated by a sun icon. Press the Fn key along with the brightness key to adjust the brightness levels. If this does not work, you may need to adjust the settings in the graphics card software for your specific model of laptop.

By utilizing your graphics card software and adaptive brightness settings, you can troubleshoot and fix the issue of Windows 10 brightness control not working. If you continue to experience problems, consider reaching out to customer support for your specific device or consulting the manufacturer’s FAQ and support resources for further assistance.
