With Windows 10 October 2018 update Microsoft has Introduced An automatic Video Brightness Feature that automatically adjusts video brightness depending on the ambient light. It uses the light sensor on your device to determine the amount of surrounding light, and then based on a predefined algorithm, it adjusts video brightness in order to improve image quality and make it possible to view objects on the screen even in direct sunlight.
- “There’s a new viewing mode for you to try out, designed to improve the visibility of your video when you are in a very bright environment. This feature uses the light sensor on your device to detect your ambient light and automatically adjusts your video accordingly,”.
- The auto brightness feature is already available in the latest Windows 10 build and you would need to go to Settings> Apps > Video playback > “Adjust video based on lightning” to enable it on your PCs.
The new feature automatically adjusts the video brightness depending on the light. It works on similar lines to the auto-brightness feature on Windows 10 Mobile.

In order for this feature to work, your device must have a light sensor. There are a couple of different ways you can check:
