My 2012 27-inch iMac has image retention

I finally got my 27-inch iMac today and the first two things I decided to do were install Guild Wars 2 and copy data from my external drive. I minimized the GW2 installer and noticed that I could still see it on the desktop. I moved the copy status out of the way and could still see it as well.

Is anyone else having this problem? I don't want to go through what others have with the Retina MBP. I believe all of the iMacs are using LG panels, so I'm not sure if it is worth exchanging over.

Thumb resize.

Here's my thinking...

1. Right now these machines are impossible to get.
2. The problem may go away on its own as the panel wears in.
3. You have a warranty for 1 year.

So what I would do? Run it as is for now and see if it improves. If not, schedule a repair w/ Apple. I also highly recommend AppleCare on iMacs, as the LCD panels are prone to issues over time. (You can get AppleCare any time within the first year)

As someone who also has AppleCare on a new late-2012 iMac, I +1 this.

But it does make me laugh when I think of all the people who still think IR can't happen to an LCD/LED or IPS display. (Mostly hear this on the TV side of things, where people spread FUD about plasma displays, saying that only they can experience IR.)

Wow, that is annoying. Is it 21.5 or 27? You would think Apple would sort this.

think of it as a flavor saver.

Maybe they are employing that iPad trick of saving the screen off so the next time you need it "it just pops"

It's a 27-inch. I don't have any other issues with it, but this one is annoying. My last few iMacs have not had this problem. I believe the last screen that I had this happen on was a 23-inch Cinema Display.

I see the IPS glow that all IPS displays have, but there is no backlight bleeding. It looks perfect to me.

Is the image retention more visible on a dark gray background? I find it very odd that the iMac would pronounce this defect since last year's models didn't. Is it possible the display technology is different this time around? I'm very worried about going through this issue again after experiencing multiple returns/exchanges for my rMBP. I'm just gonna hope there were three manufacturers (or more) for these displays, LG, Japan Display, and Sharp. Between these I would prefer Sharp if anything, LG no doubt produces amazing color accuracy, but I just can't accept image retention worsening over time and conflicting with my animation projects.

I will be receiving my iMac in a few hours and I'll check this and other common screen defects to update you guys.

I turned the brightness down one notch -- it was at max earlier -- and it doesn't appear to be retaining an image now. I run at maximum brightness on the 21.5-inch I sold, but this 27 at max seems much brighter.

Search Google for what Mac retina screen do I have... You'll get the terminal code. That will tell you. All new iMacs are LG ... I think.

My brand new BTO 27" is doing this too.

Not sure what to do. I was transferring some files and left the window open for about 20 minutes. I then opened photoshop for the first time and the gray background made it immediately clear that there image burn was present.

Also, parts of chrome browser are appearing as burn after only 5-10 minutes.

I am 2 hours from an apple store, and new BTOs are a month out, how do I deal with a return, etc? Is that what I should do?

Sorry to hear. Was this an issue with the 2011 models? Call Apple and see what they say, perhaps they can allow you to keep this one until the replacement comes in?

my 2008 iMac also had screen retention almost from the start. Add to that, backlight bleeding and yellow tinting issues (I have a spyder 3 and i can't get rid of the yellow tint completely). It didn't improve over time, for the price paid, I suggest you return it. I always had regrets about keeping mine.

I say call Apple about this issue. It may be that the display still hasn't "dried" but I wouldn't expect it to be this bad.

Hope this is not a widespread or major issue as I'm still waiting for my 27", but I do have Apple Care so worst case wait a month and if it's no better I'd return it when you're more likely to get a replacement quickly.

Sorry if this has been asked but how does the exchange process normally go, do they send you a replacement first or do you have to send it off and wait. As my iMac will be my work computer and I can't be without it.

ETA - okay read the posts (well most of them) and it's hard to tell how many have this issue. I'll check mine when I get it. 27" with i7, 680mx and 1Tb Fusion.

With an issue like this IMO if you ordered though a store they should order a replacement then when it comes in take in the old one and they should transfer your data and wipe the old one in front of you.

Seems this issue is potentially produced by a certain manufacturer, if anything. If I remember correctly based on articles, I think there were three vendors that produce these displays, LG, Japan Display, and Sharp. So I would assume it is either Sharp or Japan Display since there have been little complaints in regard to this problem, including myself, and LG is most likely contributing most of the previous generation and current iMac screens. Also, it is unfortunate that Apple blocked the information when using the display command code, and the only way is to open the iMac.

I hope Apple sorts things right soon since I have already requested a replacement for cosmetic marks on my screen, backlight bleeding, and yellowish tints.

update on iMac #2

Thought it was time for another update

I have noticed a bit more retention on my second 27" iMac after about 5 days of use. I can't confirm that it has to do with disk usage but I'm still guessing it has to do with heat.

I have installed iStat Menus and have been keeping an eye on the temps... but I haven't totally correlated it to retention as I am busy during the day and tho I want to help Apple here, it isn't my "job"

istat shows temps are pretty consistent - ranging from about 110 f to 130f during the day.

I do still notice on this second machine some significant retention but it isn't as bad as the first machine I had.

My "solution" so far has been to set the display to shut off after 20 minutes but I have the screen saver kick in after only 2 minutes of non-use. This seems to clear out almost all retention for me if I happen to get up and leave my desk for a bit.

Obviously that isn't a perfect solution, but it may help some of you. It seemed to me that if I left the default at turning the screen off at 10 minutes (i think that is what it was) then the screen saver wasn't running long enough to remove the retention.

Hope that helps some.

On neither machine have I seen any issues with Dock Icons strangely enough. Tho I would have expected to see something there. I do not turn on hiding unless I want to check to see if the icons are burning in

I'll be testing that theory tonight because I'm going to back up all of my data so that I can return the iMac to the Apple Store tomorrow morning. I won't be exchanging for another one, though. I'm picking up an external display and will get something else to last me until the Mac Pros are updated. I just don't have time to deal with this and don't care to play the good panel/bad panel lottery.
That would seem a bit strange to me - isn't the hard drive only in one small section of the iMac body and wouldn't the retention be stronger near that heat source?

Thanks for the update.

My retention seems to be semi-permanent. Even the oldest ghosting is still visible, though much dimmer. My desktop background is also being retained. My desktop picture is of a snowy mountain landscape, and since the snow is a bright white, I can see the outline of the landscape on a grey screen. It makes using any photo or video editing software with a grey background unusable, in my opinion.

The ghosting of my dock icons even show color. And like the other retention, it has become semi-permanent. I can see multiples of dock icons due to opening up apps that aren't in my dock and that pushing existing icons to the side.

I backed up all of my files last night, and it didn't seem to affect the retention. I could try duplicating my first days activities, copying files from the external to the internal while downloading Guild Wars 2 just to see if I could make it worse, but just as you said, it isn't my job. Haha.

I didn't return the iMac this morning, as I had planned, because I need to get some things done with it this weekend before I go back to being without a computer temporarily. I did go to Best Buy today and test the 21-inch iMac. I didn't pull up the grid, but I did pull up the grid website to look at the grey screen, and I couldn't see any hints of retention. I also couldn't see any hints of retention on a 27-inch Apple Cinema Display. However, the Retina MacBook Pro on display looked exactly like my iMac. I could see where previous browser windows had been open on the screen.
