Question Small horizontal pixel lines on top and bottom of my monitor screen ?

[Zoon]

I have an Acer Nitro VG240YS monitor connected to my GTX 1650 through DP. they change colours as you can see:

anyone got an idea what is causing it ? im sure that the cable is plugged in all the way. it is more visible on colours like green, blue and red

Start by manually downloading the drivers (GPU and monitor, if applicable), reinstall, and reconfigure.

No third party tools or installers.

Ensure that you get the drivers directly from the manufacturer's website. Just because the manufacturer's name may appear in the URL that is not a guarantee that the website is the actual manufacturer.

I did some testing by myself. tried out different video ports and a different cable(hdmi) they both produced the same issue.. so i switched my IGPU on from the bios and plugged my cable in the motherboard. same issue persists soo i kinda figured its the monitor by now

Appears so but worth another look and a bit more troubleshooting.

If possible try the monitor on another known working (no small horizontal pixel lines) system.

Do verify that there are no drivers for the monitor. Visit Acer's website - be sure that the website is truly Acer.

= = = =

That all said if the problem is simply cosmetic - likely you can ignore the line and save the money towards a newer monitor when the Acer is no more....

And in the interim some update or other change make cause the lines to disappear.

i installed the latest drivers on the official acer website. i also have a secondary monitor using the hdmi port of my gpu and it has no lines. so im sure its not my gpu bc i tried the broken monitor with an hdmi cable aswell!

"That all said if the problem is simply cosmetic - likely you can ignore the line and save the money towards a newer monitor when the Acer is no more...."

my monitor is working perfectly fine and those lines are cosmetic indeed but im afraid they might be a sign for something greater.. the lines are very sharp and obvious on brighter colours like green blue or red. its still in warranty so i wanna use that warranty in smth useful.

The lines may or may not be a sign of something greater or worse waiting to happen.

In any case, there is an apparent defect and you should return the monitor for a warranty replacement.

Try applying pressure to screen with your finger at edge of the screen, where pixel line meets bezel.
I'd suspect a contact problem between lcd panel and underlying contact pads.

The problem(s) are likely inside with respect to circuit boards, components, soldering, etc..

Not visible from the outside and if you open the monitor to look you then violate the warranty.

often caused by the following: Overheating or physical damage to the monitor and connecting cables. Conflicts between the screen and selected screen resolution. Incorrect refresh rate settings.

well the monitor is clean no scratches no cracks no nothing.. the cable i tried different cable. overheatin i turned it off and im sure it was cold. aint heat neither. i have it on 1080p which is its optimal resolution. and the refresh rate is what its rated on.

Did you try applying pressure at edges of screen as suggested in post #8 ?
