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.

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.

Obviously I am not a psychopath and use everything in dark themes so this "feature" makes it hard to see everything.

Please help.
