Strange stripes down screen on new imac.


Well-known Member
OK at first it didnt bother me but now it does as its quite apparant on boot up, boot down and on white displays, there seems to be a few vertical dark stripes down the screen of the imac, anyone else get this, theres none on the apple cinema display I got with it.

Theres also a few small what look like dinks or nikcs behind the black stripe that goes across the bottom of the screen on the glass, its behind it, a sif the screen inside frame black has been scratched off.

Its more obvious then it comes acros in the pictures.

I experienced some markings on my screen at start-up/shutdown when I first received my iMac. It became apparent that they were caused by the static dock icons at the bottom of my screen (i.e image retention).


I toyed with returning it, but I changed the dock to only showing when I move the pointer down and it was gone within a few hours use, never seen it since.

I can't really pick out the markings in your photos, but the cause may be something similar?

Mine does that, except mine's a Mac Mini with a non-apple display so it's not just your iMac...

If it's new I would back everything up / clone your disk then just put in a help / warranty call. It shouldn't do that. :) Apple normally very good with this sort of thing IME.
