How To Enable Or Disable Auto Adjust Video Brightness Based On Lighting In Windows 11

Windows 11 brings a host of new features designed to enhance user experience, including an improved display and power management system. One of the most convenient features for users who watch videos on their laptops or desktops is the ability to auto-adjust video brightness based on lighting conditions. This feature ensures that your screen adjusts dynamically to match the ambient lighting, providing a more comfortable viewing experience.

In this article, we’ll guide you through the steps to enable or disable auto-adjust video brightness in Windows 11, explain the benefits of this feature, and provide troubleshooting tips for common issues.

What is Auto Adjust Video Brightness Based on Lighting?

The auto-adjust video brightness feature in Windows 11 allows the system to automatically change the brightness of the videos you’re watching according to the ambient lighting. This ensures that the video brightness is comfortable and does not strain your eyes in varying light conditions. For example, if you are in a dimly lit room, the brightness of the video will decrease, and in a bright room, the brightness will increase accordingly.

This feature leverages the light sensors built into many modern laptops and devices to detect surrounding light levels. Not only does it provide a better viewing experience, but it can also help save battery life by optimizing screen brightness.
