    So I just noticed a weird blotchiness in the upper-right corner of my 27" i7 iMac's display. Almost looks dirty, but I've cleaned the deuce out of it and it's still there.

    Anyone have a similar problem? Unfortunately, I'm all out of warranty at the moment, so my last hope of free repair is if I do it or convince Apple it's a hardware defect.

    I have that same type of defect on the ACD 27", bottom right corner, looks almost like someone dripped some paint on my screen.

    Yes! That's a good way to describe it. Slightly translucent paint drips. Looks fine on patterned backgrounds, but white or light-colored bits are terrible.

    A photo would help describing your problem. But if im not mistaken by your description then i suffer the same problem.

    Popular term for your problem would be iMac "smudged or smokey display". Quite common indeed, google that and you'd be suprised.

    Looks like dust deposition from fan, am I right? Overtime it will get worse and sporadic. Im bringing my iMac in for this problem, they'd replace the display for free if u havent OoW. But no guarantee they wont ome back in near future.

    They say it caused by overheated area behind lcd. You know the screen is put in front of heatsink and all hot stuff for the sake of thinness.

    Next time I buy a Mac, I'd get a MacPro & display. Yeah it may look like normal computer and less apple-ish but at least they dont suffer from poor design like this smokey screen on iMac.

    Does look dusty, yeah. I'll see if I can get a good picture of it tonight.

    I called Apple support today and they suggested I bring it to a local store for evaluation. If it appears to be a hardware defect, they'll repair it for free even if I'm out of warranty. Here's hoping for that!

    Anyone know what the substance is? Is it messed up crystals or just some stuff on the LCD panel that I could clean myself if I suction the pane of glass off?
