This guide will help you easily turn the Adaptive Brightness feature on or off on your Windows 11 PC. Adaptive Brightness changes your screen brightness automatically based on the light around you, so your screen looks good whether you’re inside or outside.
If you like, you can still adjust the brightness manually using the brightness slider after turning on Adaptive Brightness.
What is Adaptive Brightness?
Adaptive Brightness uses a sensor in your computer to detect the lighting in your environment and adjusts your screen brightness automatically. This helps reduce eye strain and saves battery life on laptops.
How to Turn On or Off Adaptive Brightness
Option 1: Using Windows Settings
- Press Windows key + I to open the Settings app.
- Click System on the left side.
- Click Display on the right side.
- Find the Brightness section and click to expand it.
- Look for the option “Change brightness automatically when lighting changes”.
- Check the box to turn Adaptive Brightness On, or uncheck it to turn it Off.
- Close the Settings window when done.
Option 2: Using Windows Terminal
If you like using commands, you can create a BAT file to quickly turn Adaptive Brightness on or off.
