I know this problem usually takes over 1 year to show up and it’s hard to tell at this moment. So if there’s no one can answer this question right now, I’ll just leave this question here and if someone have the same concern later, maybe there will be a answer then. (Maybe I’ll answer this question myself then) Update (08/17/2017) This is case shows all 300 imac (2015 version) have dust in their screens.
Technically none of the ‘Thin Series’ from 2012 onwards have this issue unlike the 2011 and back have a dust issue. But! Apple has had a few bumps with the display makers with insects caught in the sealed sandwich. The first versions had a small weep hole so the atmospheric pressure could be equalized which maybe how the little guys got in. The newer models have a more breathable foam which should be better unless the insect bores its way though. I suspect the newest infestation was the foam tape was not properly sealed so sitting on the shelf the insects made a home only to discover to be on the inside surface of a sealed space. In any case Apple has been good in replacing displays which have evidence of insect infestation.
I have a 2017 5k iMac and yes it is beginning to show dust in the bottom corners, just like in the pics, only not quite as large yet. It is not burn in!
Chimin in as the owner of an iMac. 2017 models are still susceptible from what I have gathered. My “advice” would be to try to get the screen swapped as soon as possible within the warranty or apple care period. My understanding is that Apple is aware of that problem, and they won’t try to deny it. Many people were able to get the screen replaced — a guy an YouTube cleaned it manually, which could be another option if your mac is no longer under warranty and feel brave enough. This is such a shame, iMacs (especially retina ones) are gorgeous, and the whole concept of having an entire computer embedded in a gorgeous screen is imho unmatched. I am wondering if iMac pro will also be susceptible to that issue, as in a few years, they will be cheaper.
I’ve owned 4 iMacs in the last 13 years, and they all (except my current 2017 model) had fan noise / overheating issues after 2-3 years, which is why I replaced them. I never noticed the screen issues, but will pay more attention with my 2017 model. If it starts having problems in the next year or two, I may no longer buy iMacs.
Hi, just noticed dark shapes in the bottom corners of my iMac 21.5” 2017 4K. Is this dust? Can it be fixed and how? Thanks!
Currently a Class Action going on for this. https://www.hbsslaw.com/cases/imac-retin…
