Horizontal lines at bottom of the screen for z271u Is there anything I can do about this?

I have some horizontal lines like this user:

My monitor is from 2019 and I am out of the guarantee period. Is there anything I can do about this?

It is happening on different PCs, on booting, so a permanent new feature :(

In the photo below you can see that I made a screenshot with the snipping tool where this error is not on the screenshot.

It's a problem similar to televisions. I would check the edp cable:

Typically those types of artifacts are caused by the cable, as suggested, but either the DP or HDMI cable you are using between the desktop and monitor. Only tear into the monitor itself if a good replacement cable makes no change.

I am using a DP cable for my desktop and the hdmi cable for my business laptop. Both devices have the same problem. So I don't think that this is external cable related.

The EDP cable sounds promising. I saw in the ACER shop that there I can get a new one. How can I get your pdf manual? On the acer support page I found only the regular one with 39 pages. Yours have 86 pagers.

The Service Guides aren't publicly available except to service centers and a few lucky members here. We are allowed to post snippets from them though, such as you see above.

I bought a new edp cable from acer and see unfortunately the same effect.

Additionally I switchted the DisplayPort cable. This does not help either.

Do you have other proposals what I can do?

Is your monitor still under warranty?

Nick82

No my monitor is not under warranty any more. See my first post.

In that case, I advise sending the monitor to a technician who understands electronics.
