The ability to adjust the brightness from your PC can be very useful, but many users have reported that this option is not available on Windows 10. One of the reasons this happens is because of your old video driver. These speakers are no longer stable in terms of your display setting.

Your monitor driver can also be disabled, which automatically prompts Windows to upgrade to older versions. Often, these versions do not support changes in brightness. In some cases, the brightness settings may have been deleted. If you cannot find the option to change the brightness anywhere on your taskbar or in the Notification Center, here are the methods to help you solve the problem.

Update your Graphics Card Driver

  • Press the Start Menu button, then type Device Manager, and select it from the list of available search results by simply clicking on the first one. Or you can type Windows Key + R to access the execution.
  • In the dialog box, type devmgmt.msc and click OK to run it.
  • Expand the Display Adapters pane, right-click on your video card and select Uninstall Device.
  • Confirm any pop-ups or prompts that prompt you to confirm the uninstallation of the current video driver and wait until the process is complete.
  • On the NVIDIA or AMD input, locate the driver for your video card, find the information you need on the card and your operating system, and then click Search or send.
  • Click on the name, then click on the Download button. Save it on your computer, open it and follow the instructions on the screen.
  • When you access the Installation Options screen, select Custom (Advanced) before clicking Next. You will see a list of components to be installed.
