How do you change screen brightness in Windows 10 and 11

There are different ways to adjust the screen brightness in Windows 10 and 11. You can either adjust the brightness yourself in the operating system, have the brightness adjusted automatically, or change the brightness directly on the external screen.

Windows offers you the possibility to change the screen brightness progressively. This works for both Windows 10 and Windows 11.

The screen brightness can be adjusted with a shortcut so you avoid having to take a detour by navigating around lots of menus. Many keyboards have two F keys with a sun symbol in the top row. The “Adjust brightness” function is assigned to these keys as a secondary function. To execute this, press the [Fn] + [lighter/darker] keys simultaneously. Repeat this brightness control process until the desired brightness is set.

The Action Center is a quick way of accessing various settings, including the screen brightness settings. Windows 10 and Windows 11 both have these options, although the terms they use are slightly different.

To open the Action Center, left-click on the speech bubble icon at the bottom right of the taskbar in Windows 10. As a Windows 11 user, you will find the option after clicking on the network icon — also at the bottom right of the taskbar.

If there is no brightness control slider in the Action Center box, look for a tile labeled “Brighter” or the sun symbol. Keep clicking on the tile with the left mouse button until the screen is bright enough for your needs.

On computers with external monitors, the brightness is usually adjusted directly on the monitor instead of the operating system. Using the physical buttons on your monitor, you can call up the on-screen display, which allows you to adjust the brightness. The exact position of the buttons and the structure of the on-screen menus depends on the device and manufacturer, but there are usually small symbols on or above the corresponding buttons to guide you. If you’re in any doubt, refer to the user manual for your monitor to find out how to change the screen brightness.

Some computer models have an integrated light sensor, which enables the screen brightness to adjust automatically to changing light conditions. It can also be found in the system settings.

The night mode in Windows also offers automatic adjustment. However, instead of using the actual lighting conditions to adjust the screen brightness, it works depending on the time of day. Users can either set a period for warmer lighting themselves or use sunrise and sunset times. Windows is already aware of these times.
