Cinema display-discoloration, stain ? ?

[Andylar]

Hi All

Has anybody come across this problem on a cinema display, its like a stain/dirt
underneath the actual cinema display ?

It's a known problem on the displays and the iMac's. Probably dirt/dust or something. Best thing to do if you have AppleCare is take it in to them and have them take a look.
