How to Enable or Disable Adaptive Brightness in Windows 10

information   Information
Displays (especially on laptops and tablets) may utilize ambient light sensors to detect surrounding levels of light.

The adaptive brightness feature in Windows monitors ambient light sensors to detect changes in ambient light and automatically adjust the display brightness as needed to match surrounding lighting conditions.

While adaptive brightness is useful to help save battery life, it may at times cause your display brightness level to be too dark.

This tutorial will show you different ways on how to enable or disable adaptive brightness in Windows 10.
