    How to Adjust Screen Brightness in Windows 10

    information   Information
    If you have a laptop or tablet, you might need to occasionally change the screen brightness. For example, if you want to use your laptop outdoors on a sunny day, you might need a brighter screen to see the display clearly. Or, if you're in a dark room, you might want to make the screen less bright.

    A brighter display uses more power, which reduces battery life.

    This tutorial will show you different ways to adjust the display screen brightness on your Windows 10 laptop or tablet.

    Note   Note
    If the Screen brightness option isn't available, your PC might not support brightness adjustment or you might need to update your display drivers.

    Hello Ruu,

    Is this a PC, laptop, or tablet?

    If PC, then the screen brightness setting won't be available.

    It's a setting only available on tablets and notebooks.

    You should still be able to manually adjust the brightness level with the monitor's on screen settings though. Check your monitor's manual for more on how to do so. It'll usually be a button at the bottom of the monitor to press.
