How to Turn On or Off Auto Adjust Video Based on Lighting in Windows 10


Starting with Windows 10 build 17704, there is 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 (if available) on your device to detect your ambient light, and automatically adjusts your video accordingly.

Microsoft would love feedback as they work to refine this feature for the next Windows release! Please use the Feedback Hub and file feedback under Category: “Devices and Drivers”, Subcategory: “Video Playback”. Hit “Recreate my problem” and start the capture of the video playback you would like to give feedback on!

A couple notes:
  • In order for this feature to work, your device must have a light sensor. There are a couple different ways you can check:
    • Go to “Display Settings” in the Settings app. If you have the option to turn on Auto-brightness, you most likely have a light sensor.
    • Go to Device Manager. If you have something that sounds like “Light Sensor” under Sensors, you likely have a light sensor.

  • Currently, not all devices have light sensors that are well-calibrated. If you are on a device where video looks really, really bad with this setting on, please let Microsoft know via the Feedback Hub.

This tutorial will show you how to turn on or off automatically adjust video based on lighting for your account in Windows 10.
