Are you for real?
It makes sense to take the photo in portrait orientation as opposed to landscape as that whats the medium dictates.

I was having a major image retention problem with a new 27" iMac purchased at work. Apple Store folks call it image persistence, and I refer to it as after-images below. Took it to a store and a replacement will be shipped to the store. Notes:
- Doesn't happen until the system is warm.
- The after-images are most visible on a dark gray background, and are invisible against a very bright or completely black background.
- When the problem first starts to kick in as the system warms up, blue after-images show up first, followed by green.
- Certain blue or magenta images result blue after-images.
- Certain white or yellow images result in green after-images.
- Green after-images are far more common than blue after-images.
- After system is warm, it takes about two minutes for an after-image to become noticeable, and it becomes strongest after about 5 minutes.
- Takes about 20-30 minutes for strong after-image to fade away after switching to a dark gray background.
- Rebooting doesn't not clear an after-image.

No matter what resolution I use on my retina macbook pro I still get it. I'm reluctant to get Apple care because I'm in a remote area and haven't been helped yet. Here in Canada you cannot send in your machine for repair past the 14 day return policy. I have been to two licensed Apple techs and they both say my macbook tested fine.
My next option is to continue talking to an apple supervisor on the phone when he returns tomorrow. Hopefully I can get a new one sent to me but I highly doubt it.
funny you mention that because ive always had this one black wallpaper ive used in particular in all my other iMacs and never noticed ir...since ive gotten my new one ive been using the stock wallpaper of the galaxy since i never got around to changing it and have sinced noticed it, so all i know is all my imacs could of had it and i just never knew, ive noticed after i did the reinstall and all that it does come back but it takes 45 minutes now, instead of 10 and when i put my old wallpaper pack up thats mostly black i never notice its there, so now iv got a dilemma, do i just hang onto it and forget about it being there (out of sight out of mind sort of thing) or do i send it back, wait another month, only to get another machine with the same exact screen...because this isn't like the rmbp situation where if you got a samsung screen your all set, these are allllllll lg screens nowI was having a major image retention problem with a new 27" iMac purchased at work.

Did little experiment today at local apple store (Freehold Mall NJ). Launched chessboard page (http://www.marco.org/rmbp-irtest.html) on 27 and 21 iMac for 10 min and then switched to gray page, adjusted brightness of both monitors to high and low brightness on the gray page as well as on desktop background - no retention at all, not even a little "hint" to retention
You are the man! Awesome move...thanks from everyone here. In my tests, I have not seen any IR on the new iMacs on display ... so this is continuing confirmation that if you get one with IR, it's really a defective display and you need to get it replaced. Keep the updates coming!
Just to be clear...
My 27" has no retention most of the time, not even a hint of it with the grid test, even if its been on for hours.
However, if you do anything processor or hard disk intensive, it will easily develop retention with the test.
I don't think you can test for it easily in store, without at least pushing the machine for a bit before running the test.
So maybe it's an issue with heat then? Maybe the screen used in the new iMacs doesn't tolerate heat very well, resulting in image retention when the CPU and/or GPU is running hot..
My iMac is arriving in a day or two, getting a bit nervous here. Really hope my iMac doesn't have any of these issues...
I've tried to induce a stress test resulting in IR, by playing 3 HD movies, whilst simultaneously copying 30GB of files. No IR, not even after playing a game in Windows for hours, restarting back into OS X and pulling up the grid pattern.

Thanks! Could you please post your specs (cpu, gfx etc.)?
Absolutely agree, you can't do this type of test at the store.Just to be clear...
