    Any other 27" LED Cinema owners noticing grey spots forming behind the glass? Over the last couple of months these spots have grown over the bottom left and right corner of my display. They are only visible when a light color is displayed on the screen but annoying for this level of perceived quality.

    My iMac developed this and was sent back for repiar, then I bought a 24" ACD for my Macpro and within a few months I had all these grey smudges all over the bottom left and up the left side of my screen, this was sent back, and within a few months they are back again.

    These smudges will be inside the layers of the panel itself not just behind the polymor front screen.

    I will never ever buy another ACD from apple.

    My screen as is at the moment, little square top left is just a reflection.

    Okie land
    They say that is the backlight dying.

    I have had two LED displays repaired for the exact same problem.

    Sorry but that is dirt inside the panel, nothing to with any backlight issue.......

    Apple flat screens/acds are crap........
