I need help with my monitor

[MxKeks]

Well i realized a weird and pretty annoying problem with my monitor. I have a multi monitor Setup and on my main screen (Asus ROG PG278QR) some images look really bad in quality compared to my second screen (some cheap lg 100-150€) one.
To show you i made some pictures with my phone, see for your self. The Problem is this pixly look on black/grey areas

 

The main monitor (Asus)

 

 

and down below my secondary monitor (LG)

 

 

If you know what to do please tell me, because, i am out of idears

I looked a little deeper into it

and i created this Test Picture

The Image looks like that on my Main Screen,

and both sides the same on the second monitor

looks like clouds from the backlight also you should check the connections just to make sure.

Well, I already tried to connect the Monitor with the HDMI from the second monitor but, that didnt halp the issue. Clouds from the backlight ? What could i try do to fix that ?

Hmm looks like i fixed it by lowering the gamma. Thanks for your help
