Hello guys,
I have a weird display issue which is hard to explain.I actually got the issue for a while.
My OS version is 10.13.4 and I own a late 2012 27-inch iMac.
iMac, macOS High Sierra (10.13.4)
Hey Kaid,
I'd recommend starting the iMac in Safe mode as well as resetting the NVRAM and see if that helps 🙂

Okay I'm so confused now.I need to tell you that it sometimes disappears and sometimes plop up randomly in my screen.Sometimes there are very small green lines and a safari site appears on my desktop aswell but it is green.
What me really makes me crazy is the fact that my screenshot didn't took it up.
I did both things but sadly it didn't helped me at all.
What is currently happening on the display after the resets?
Actually nothing.The display issue is still there.
Could you upload the issue externally to show it in more detail as the picture here in the communities is rather small.
Just right click it and download it.
What for an issue do you have? I can’t find anything what’s wrong.
When the problem is plopping up I think I'm gonna take a photo with my mobile.
When a display issue is not visible on a screenshot it’s likely a hardware issue. So make it with an iPhone is a good idea.
Do you think it could be the graphics card?Or the maybe the screen?
I don’t know. You can make a hardware test maybe with holding D during start up
