I didn't manage to disable Dolby Vision only, but turning HDR off should do the job. I don't know how to disable Dolby Vision leaving HDR on.

Brilliant - that worked, insanely frustrating that this is so hidden.

Wow disabling Windows HDR worked for me too. So I guess we'll have to enable it manually if we want to watch HDR-enabled content and keep it off when doing regular work. Terrible...

@Turista this is standard across all laptops worldwide. HDR is energy consuming, so you don't want the battery lasting you about 2-3 hours because of it. You could enable so everytime you plug it in it turns on HDR if you would like tho.

You can disable the windows hdr by turning of "hdr games and apps". The option is located in the windows "display settings" While hdr video streaming option and hdr apps and games option toggled on in windows (and ac plugged in) are you guys experiencing changing screen brightness/contrast while watching for example dolby vision content on netflix? Im doing so and some statements in this thread sounds same, but i want to confirm the issue. For me while having above described hdr options turned on and streaming a dolby vision movie, it occurs that in some case as there is a bright scene switching to a dark scene the screen brightness seems to be changing and its like the screen is trying to adept the contrast, even if every adaptive contrast setting is turned off (tried regedit too) and ac is plugged in. You guys experienced same the same issue already?

Hi! So going into regedit and changing from 200 to 210 did not work for me, but I found something that did. Open Intel Graphics Command Center from start menu then go system > power > on battery > and turn display power savings to off. 

 

My issue might be different from your issue, what I noticed is that when I had the brightness turned all the way down, while sitting in a dark room, the display would turn off completely when I switched from a window with a white (or very light) background to one that had a black (or very dark) background. I haven't noticed much of a white-ish screen, but then again I didn't notice the brightness changing unless I was in a dark room. Changing this setting to off fixed my problem and the screen doesn't turn off when switching to window with a dark background. Anyways, hope this helps!

So far this answer has worked. Thank you so much (and thank everyone else for the other helpful suggestions) to fix this problem.
It does suck that it takes such a hard work around to find out how to fix such a simple adjustment. Every website I went to kept saying 'oh go to power options > adjust the settings > Display > Turn off adaptive display... But im like.. uh yeah my laptop doesnt even show that as an option.

 

I also went ahead and download all of the Intel updates etc using that Intel Graphics Command Center as a jump off point. So again thank you. I hope this remains the fix for the problem.

I do was having my screen auto dim when switching from light (reg webpages) to dark (netflix, videos, etc) screens and it was pissing me off! LOL.
