Hi all, long time lurker, first time poster!

I've recently purchased a 2015 27" iMac with i7, 512GB SSD and M395x GFX card.

The display has some strange artefacts behind the glass, almost like screen burn/ ghosting but not? I've tried all the recommended tests to alleviate this but have had no joy. Its most prominent on a dark grey background and not visible if I set my desktop background to white or black. It shows up almost like a zigzag rather than a hard straight line.

Sorry, the phots aren't great and it looks worse to the naked eye.

Can anyone suggest what the issue might be before I send it off for repair?

Thanks in advance! :)

Hello,

I already saw some posts about this issue here on the Forum so you're not the only one. I don't know much about it but I'm surprised people didn't reply. I'm sure someone will help you.

Thanks. I did do a bit of research but couldn't find anything similar but I may have been searching for the wrong thing!
