Windows 10: Weird lines on the monitor

Hi, all of a sudden my monitor HP Omen 25" 144hz using a display port connected to an assembled PC with NVIDIA 1660 running windows 10 started presenting weird subtle horizontal gray lines and I noticed almost like a drop in the video quality, I checked the settings for the resolution and everything is like before, nothing changed... It seems like it came with the last 22H2 update. So I started excluding some things:-I connected a laptop with a HDMI to the HP monitor and everything work fine, no lines, so I guess no display issues-I connected the assembled PC to another monitor using a HDMI

:)

 

What is this weird horizontal line?



There is a weird line at the very bottom of the monitor, it starts as black, but when the mouse is moved to the line it changes colour.

 

Weird, subtle horizontal lines on monitor

Suddenly today one of my monitors started looking weird, with these subtle horizontal lines covering the entire screen, along with some weird color transitioning.

It's hard to describe and the picture doesn't help a lot since I'm taking a picture of a screen, but I tried my best you can see it kind of cuts the letters and the numbersz also the marker on the right is cut up into pieces, it's a lot more noticeable with the eye. On the second picture you can see the weird color transitioning.

I don't know what caused this, as it was working perfectly fine earlier today.

 

GPU-Z what command line parameter ?

Suggestion: /? (-?) and /help (-help) command-line arguments to show a list of all possible arguments in a small window. *Smile
