Horinzontal line on monitor only at 100+ Hz

[Cris23012]

Hi! I own an BenQ ZOWIE XL2411 running on 144 Hz via DVI Double Link and today I noticed a faint horizontal line (just one) slightly above the center of the monitor. The line is 1 pixel wide I think and is clearly seen on grey background and less noticeable on other colors. I bought it less than a month ago and had no problems before. I noticed that the line is visible only at 120+ Hz. If I run at 60 or 100 Hz I don't have that line. Can this be a software related issue or is my monitor broken?

Does your motherboard have video ports?

I think not. The monitor is connected to my GPU via DVI-D

Aside from making sure your drivers are updated, I'd start by swapping out the monitor and the graphics card one at a time with a replacement to see if the issue persists or not. It has to be either the graphics card or the monitor. Have you tried different ports on both the graphics card and the monitor?

I would be happy to try it, but I do not have the possibility. I need a HDMI which supports 144 Hz or a DVI-D which I can't buy in my town. I think my GPU is okay because it works fine at 60/100Hz. I contacted BenQ support guess I will get an answer soon.

Btw this monitor has no drivers just some color profiles for windows. Gonna try to reinstall GPU driver.

You said you were using a dual link dvi-d cable correct? Is one of the pins bent on either side of the cable? See if you can swap out the cable with something else for testing. HDMI according to this article won't run 144hz:

Just checked the cable it is okay I think. On both sides the pin highlighted in the image is slightly pushed in.http://joxi.ru/E2peW54UQ0znAY

I am okay with that line, I just wanna be sure if it won't spread so more lines or artifacts appear.
