Very specific problem. Vertical lines/pixelation, interlacing?

Hello guys,

After having a horrible experience with 2 IPS panels (I couldn't get over the IPS glow) I decided to go back to a TN panel and just bought this AOC AGON AG271QX.

It's a 27" 2560x1440@144Hz monitor with a TN panel. No dead pixels, no back-light bleeding or ghosting. So far so good.

But there is a very specific problem/artifacting I just can't get used to. I will shortly try to describe it to the best of my abilities, because after 2 days of searching online, I could never find anyone else reporting this type of issue. I just want to know if anyone has had a similar problem and if there is a solution at all.

If there is a still image on it looks prefect. But when the monitor is displaying any type of moving images, especially moving up or down - it could be in games, watching videos, or just scrolling up and down a page with photos for example, I could see the vertical lines of pixels the image consist of, in a way it looks somewhat similar to the image below, but much more subtle, not so exaggerated.

I tried different refresh rates, 60 Hz, 120 Hz, 144 Hz. I played for hours with every single option in the monitor settings menu. I even managed to find out how to pull up the hidden service menu, and played with every option there too. Nothing improved the situation.

I thought it could be the connection or the cable. The monitor is usually connected to my PC via DP cable. So I tried DVI and then HDMI - same results.

I then thought it was maybe caused by my GPU so I plugged the monitor to my wife's laptop and again - nothing changed, same problem.

When I spoke to my wife trying to explain her the problem and show her what I mean, she said she doesn't see any problems, but to me it's very obvious. I guess I've got a "more trained eye" or something.

I thought I could ignore it and not think about it but no matter what content I use - games, films, web surfing, as soon as there is a scrolling or moving up or down image displayed - I can still see it and it annoys me to no end.

Has anyone experienced such artifacts or has anyone heard of it? I'm desperate to know.
 
Hey,

thanks for the reply. I guess you only took a quick look at my post and when you saw the picture, you came to the conclusion you suggested. I did however mention in my post that I indeed tried DP, DVI and HDMI and even a different computer.
 
So... nobody here has even heard about a similar problem? It's so frustrating having to return the monitor yet again.For one month I went through 3 different monitors and they all had some type of a problem. Is there are quality control at all?
 


Actually i had similar problem with my PG278Q and what u say is "pixel inversion" and its very visible when u just drag windows window in windows 10 with solid color on top for ex. light blue and slowly move right to left and for what i know this is "normal" for this type of panel because of aggressive overdrive to achieve 1ms. even DELL S2716DG have the same issue. Now i have IPS version of AOC AGON and don't have this "problem" . Anyways can u tell me how u get into service menu in your AOC ?
