How to turn off auto-brightness on Windows 11

Once Windows 11 came out users highly appreciated many new features. Along with a centered Start menu and taskbar, rounded corners windows, themes, and colors that will make any Windows look and feel modern.

However, the brightness of the screen is very important when working with a monitor. The light from the screen has a great effect on your eyes and eyesight, so it is important to take frequent breaks and allow your eyes to rest.

While it is also important to choose the brightness level so that you are comfortable. If you have already found your comfort level of brightness on the screen, but don’t know how to save it as the default setting of your Windows 10 or 11 PC’s screen, this article will help you.

While this feature is turned on, Windows provides optimal brightness and contrast levels, and at the same time saves power and provides longer battery life. In some cases, your computer might not display content at optimal quality and the battery-saving arguments may not be convincing to you to keep it on.

How Windows automatic brightness works

Before you set the correct settings, you should understand how adaptive brightness works on the Windows 11 system. The fact is that the adaptive brightness function is only available on those devices in which the screen is built-in from the start. That can be – laptops, tablets, smartphones, and PCs that are assembled in the first place. If you have a monitor separate from the device, you cannot apply the adaptive brightness function to it by default.

Some Windows devices automatically adjust screen brightness based on ambient lighting conditions, and some don’t. If so, these changes are based on readings from a light sensor built into your device.

In addition, the adaptive brightness function on some PCs also works when you are watching content that requires less energy and saves power. Microsoft calls this option “content adaptive brightness control” or CABC. Depending on which of these features your Windows PC supports, you may see one or two checkboxes to control these options in Settings, which we’ll cover below.

How to disable Adaptive Brightness in Windows 10 or 11

In case you are tired of rapidly changing levels of brightness or simply want to stick to the certain one you should:

  • First open Windows Settings by pressing Windows+I. Or you can right-click the Start button and select Settings in the list
  • When the Settings app opens, in Windows 10, click System, then select Display in the sidebar. In Windows 11, click System in the sidebar, then select Display
