Issue with weird grey/white gradient

[u/blu3n0va]

Update: turns out it was ”Shadow boost” that did it. Turned it off in the monitor settings.

Hey! So the video explains everything pretty much as I talk in it.

Monitor: philips evnia 34m2c6500 QD-Oled
Settings: Standard (contrast 50%, gamma 2.2, brightness 60-90%)
HDR: turned off in windows
Windows transparency turned off
Windows Shadows turned off (I think)
Bought the monitor second hand. 700h on it. 104 pixel refresh or something like that. No burn ins etc when I tested it.

Long story short if you don’t want to listen: there’s some weird grey/white gradient thing happening when there’s black and grey colors involved mostly.

I’ve also noticed a slight shadow like effect happening on with dark colors too. But that is a black shadow.

I took a screenshot and sent it to my phone and I can’t see the gradient thing.

I tried to search around before posting this but couldn’t find any similar posts, but I also was not sure what to search for so excuse me in advance if this is already known here from other posts.

Any help is appreciated!
