How to Turn Off Auto Brightness on Windows 11/10

If you're tired of your Windows 10 or 11 PC's screen automatically getting brighter or dimming, you can easily turn it off. All it takes is a quick jump to Settings. Here's how to do it.

Understanding Windows auto-brightness

Before we start, we need to know that auto (or adaptive) brightness only applies to Windows devices with built-in displays like laptops, tablets, and all-in-one desktops. . If you're using an external display, you may not see the adaptive brightness controls in Settings.

Some Windows devices automatically adjust screen brightness based on ambient light conditions, and some do not. If so, these changes are based on readings from your device's built-in light sensor.

Additionally, some PCs allow the brightness to automatically change depending on what you're viewing on the screen, saving battery life. Microsoft calls this feature “content adaptive brightness control” or CABC. Depending on which of these features your Windows PC supports, you may see one or two check boxes to control these options in Settings, which we'll cover below.

1. First, open the Windows Settings by pressing the Windows + I key combination.

2. When the Settings app opens, click System in the list on the left, then select Display.

3. On the corresponding settings screen that appears on the right, look at the Brightness and Color section. Click the small arrow button next to the Brightness slider to expand the settings menu. Then uncheck Help improve battery by optimizing the content shown and brightness.

Then close the Settings app and all your changes have been saved. From now on, your screen brightness will always be maintained at a fixed level. Wish you have a good experience with Windows 11/10
