    I noticed today that there is a dust-like shadow in the lower-left corner (see the attached picture). This display was bought in July, 2011.

    I read many posts about the dust within the display of iMacs and never heard of the dust within an ACD.

    I called Apple support about this. Unfortunately, they did not register any of my two ACDs under the AppleCare of my Mac Pro (I did send them the serial numbers of the two ACDs together with that of my Mac Pro). I was told that they were going to find out what went wrong with my AppleCare registration.

    I'd personally take it to an Apple Store - that's not dust that's a problem with the lamination of the LCD itself.

    They'll either replace the LCD inside, or just swap the unit for you I'd imagine.

    Thanks for the feedback! I will let Apple know this.

    That is indeed dirt in between the panel laminations.

    I have had three Apple flat screens do this, this is the reason why I will never ever purchase another Apple monitor.

    I'm looking at the pattern. Are you sure it's specifically dirt? The pattern looks like it wasn't mounted in a completely flush manner.

    I was never big on their displays. Usually they make the most sense if you're buying an imac, as you're paying for it anyway. I'd only buy a display or imac directly through Apple due to their return policies. You can find better options for the price of a thunderbolt display unless the docking functionality is the reason for the purchase. Too many people on the site haven't compared as many of them only trust Apple on expensive computer purchases.

    Pull the outer glass (held on with magnets) and clean the outter glass and the glass front of the LCD display panel. Then put the outter glass back or, put on a MacFrame.

    That may be what I eventually do if the AppleCare does not come through. I have to wait till Monday to find out if it can be covered by the AppleCare of my Mac Pro. The "dust" seems to be on the LCD as the words in a document appear to be in the front of the "dust".

    That dirt is NOT on the inside of the outside front panel nor is it on the front of the LCD panel, it is INSIDE the LCD panel, believe me I have had same issue here inside 3 LCD panels.

    Your monitor starts life all looking nice and clean and shiny new and within a few months that dirt starts to appear and gets gradually worse, so far as I say I have had three panels do this, not good for top of the range equipment.

    I will certainly raise this issue to Apple support. Unfortunately, I also noticed the dust on the lower-right corner of this same display. However, my other ACD (bought 4 months earlier than the one with the problem) does not have this problem (yet)!
