# 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. ## Adjust brightness via the settings Windows offers you the possibility to change the screen brightness progressively. This works for both Windows 10 and Windows 11. ### Step 1: Open your Windows settings Click on the **Windows symbol** at the far left of the taskbar and then on the **gear icon** that appears just above it.

The screen brightness settings are found in the ‘**System**’ section.

In the right-hand panel, you will see a **slider** that lets you freely adjust the screen brightness. There’s also an option to turn on **Night light**. You can turn on night mode immediately (without specifying a time of day) by left-clicking on ‘Night light settings’. Adjust the strength of the night light or alternatively, simply move the slider to ‘On’.

Many keyboards have two [F keys](https://www.ionos.co.uk/digitalguide/websites/web-development/function-keys-f-keys/ "Function keys (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 on your laptop is set. Tip There are lots more [Windows shortcuts](https://www.ionos.co.uk/digitalguide/server/configuration/windows-shortcuts/ "Windows shortcuts") so you can save a lot of time and navigating with the appropriate shortcuts. ## Adjust the screen brightness via the Action Center 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. ### Step 1: Open the Action Center 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. ### Step 2: Adjust the brightness Adjust the **brightness slider** (shown by a sun symbol) to the desired level.

Keep clicking on the tile with the left mouse button until the screen is bright enough for your needs. ## Adjust the screen brightness on an external monitor 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. ## Automatically adjust screen brightness to lighting conditions 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. Tip Many users find a dark display more pleasant therefore Windows offers dark mode.
