2012 27" iMac - inconsistent white color on bottom half

Hi, is it this famous problem?

https://discussions.apple.com/thread/2300580?start=60&tstart=0

When the last generation iMac came out in 2009 there were huge issues the screens being yellow or greyish at the bottom half. On the new ones although the screen is laminated to the glass its the same screen tech from 2009 through to the last 2011 iMacs. There is a test you can try, if you are not happy send it back, my 2011 iMac is not bad but the 2009 one I had was very discolored the bottom of the screen looked dirty yellow. Try the test at the link below and see how it looks then. If you are unhappy go to a store look at other 2012 iMacs to see if they are better, if so ask for a replacement. Maybe try taking a picture of a good one to show the comparison with yours screen so they can clearly see the issue.

I just ordered my 27 (top spec except memory, got that from Crucial), so I'm very currious about any issues with this model. Have you tested it for Image Retention yet?

There are some reports of IR, hope not!

Keep us up to date and good luck!!

No but I wouldn't be posting on any forum if I did. I'd be taking that system back for a full refund and then buy another. And or taking it back for a Replacement, not to have it fixed.

So what if others have the same thing? Does that make it OK?

No doubt, if my iMac arrives with a bad screen...its going right back until they get it right. Clearly, Apple has a worsing record on their LCDs. I'm wondering when they will take that part of the supply chain more seriously.

I just got my 27" i5 today, and it was the first thing I noticed! Yellow tint along the bottom of the screen...looks nasty, going straight back.

Can you post a pic?

Are you guys kidding me with this big issue?

I just ordered my iMac 27" more than a month ago...and am still waiting.

What da hhell are they doing with their products now, unbelievable. 😠

Can I sue them if I'll have the same problem?

Contact Apple Service, iMac Service or Apple's Express Lane. It's a new machine, so let them deal with it. Repair onsite or replace.

I've just returned a brand new imac 27" for the same reason, bottom quarter of screen has yellow tint. Problem is that I have to wait several days to get a replacement, so for now I'm back to using my trusty 2006 Macbook Pro linked to a 2007 23" Cinema Display....great machine, but a tad slow running CS6.

It's sort of good to know that I'm not the only one with the yelow tint problem, but hope that the replacement is upto the quality of my old Cinema Display... fantastic monitor, but now has image retention problems due to age.

Does anyone think that the short supply of 27" iMacs is due to problems with build quality?

It is so ANNOYING - Exactly the same with my new 27" iMac. Incredible fast machine, absolutely quiet - almost perfect. But the display is the worst thing I've ever seen!!! Uneven illumination / yellow gradient down / right side is much darker than the left. Photoshop makes absolutley no sense to be used on this computer! Even the imacs exposed in stores suffer from poor panels! For testing: simply select as wallpaper a neutral gray.
