Enable Auto-Adjust Video Brightness in Windows 11

Windows 11 includes a feature that automatically changes how bright your videos look based on the light in your room. This helps you see your screen better and keeps your eyes from getting tired.

Why use this? It makes watching videos more comfortable whether you are in a dark room or a bright office.

What happens when done? Your computer will use its light sensor to dim or brighten your videos automatically.

Note: You must have a device with a built-in light sensor to use this. If you do not see the option, your computer does not support it.

Using the Settings App

You can turn this feature on or off in the Windows Settings app.

1. Open the Settings app by pressing the Windows key + I on your keyboard.
2. Click on Personalization in the left menu.

3. Click the Video playback tile on the right.

4. Click the Adjust video based on lighting around me tile.
5. Toggle the switch to On or Off.

Using the Registry Editor

Advanced users can also change this setting using the Windows Registry editor. Warning: This requires admin privileges and should be done with care.

1. Open the Windows Registry by searching for it in the Start menu.
2. Navigate to the following path: Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\VideoSettings
3. Double-click the EnableOutsideModeFeature item on the right.
4. Set the value to 1 to turn it on, or 0 to turn it off.
5. If you do not see this item, right-click an empty space, create a new DWORD (32-bit), and name it EnableOutsideModeFeature.

Save your changes and restart your computer to apply them.

Summary

The auto-adjust video brightness feature helps your screen look its best in any lighting. You can manage this easily through the Windows Settings app or by editing the registry. Remember that this only works on devices equipped with a light sensor.
