How to disable "Intel Display Power Saving Technology"?

I'm using a Dell XPS 13 9380 running windows 10 (cry).

When a bright image is displayed, the screen brightens. When dark images are on the screen, it dims. The result is constantly changing brightness. It changes whether on battery or plugged in.

I have adjusted all of my power settings to high performance. I have looked in Intel's HD Graphics Control Panel, there is no option to disable it.

Following these protocols (https://superuser.com/a/1487212/1164457), I have:

  • disabled adaptive brightness in the registry
  • disabled Intel display power-saving technology in the registry

After rebooting and confirming the settings changed, the screen still changes brightness constantly.

This "feature" makes it hard to see everything.

Had same issue, after hours of searching I found that it is a setting in the BIOS.

Here is how to fix:

  1. Boot into BIOS mode
  2. Go to 'display' tab (on some models it is under 'video')
  3. Scroll down to 'EcoPower'
  4. Turn it off
  5. Save changes
  6. Good to go!
