Windows 10: Missing adaptive brightness option

I have an HP Laptop Probook 450 G5. It got Intel 620 UHD graphics and Nvidia 930MX.


I am currently running Windows 10 1909 Build 18363.778 on my laptop. My issue is when play any video in full screen on Microsoft Edge, it automatically increases the brightness to max, and I don't like it. Somewhere I have read it can be disabled by turning off the adaptive brightness option. But I don't find any option to turn it off. Help me out, please.


Thanks.

No options to turn OFF adaptive brightness / no power slider

Hello everyone!

I'm stuck with a very weird problem I can't solve. I'm not a full-on reading binary style tech person but I'm using computers (and fix their problems) since forever and never ran against a wall like this:

My Dell M3800 laptop turned on the adaptive brightness feature again that I disabled almost three years ago. Now it's pretty much useless in dim environments because the screen gets so dark. Also every option windows normally has to switch it off is gone. Not greyed out, it's just not there (Both in the legacy power options and in te new UI).

Around the same time it happend that windows decided to get rid of the old power profiles and instead only show the "balanced" one that comes with the power options slider when you click on the battery icon in the tray. I had that briefly and then the slider disappeard along with the option of turning adaptive brightness OFF.

This makes me MAD.

• I deleted and restored the default power plans in several ways
• I changed all (all I found, though) corresponding registry entries to disable adaptive brightness
• I checked the registry for the the option to show the switching-option being ENABLED
• I even stopped the windows service for the ambient light sensor

No change. Any Wizards around? *Shock

Brightness options completely missing

No there are not. I'm no expert on this but "feels" like if I can get the system regocnize the display I'd had a chance to get this problem solved. Is that assumption way off?
I can get some more screenshots in few hours of the missing brightness bars if it helps
