You unfairly criticize and chastise people for claiming to have a yellow screen. You tell them its their imagination and that photos are useless. You're a big hypocrite as you yourself have had the yellow tint problem and have suggested ways for other posters to post photos of their screens. My posts are mere evidence of your contradictory ways. To characterize TWO posts as repetitive is hardly graffiti, especially when they ARE well placed and in direct contradiction to your own posts. You are a sadistic individual with no empathy for others. Clearly a psychopath in life it would seem based upon your unsavory posts towards others.
Cry to the mods all you want. You're really the little child here who is throwing a little tantrum. All one needs to do is see how arrogrant and hubristic you are towards people looking for a little helpful advice on how to proceed with a defective machine. I'd invite the Mods to review your attitude towards other members. I would imagine they give you a little vacation. It seems many many other MR members complaint about your posts quite often.
Oh and yes, I do have plenty of positive things to say of Apple products, you just dont read those threads. Your only concern is when you've been told your wrong, that you begin to cry and demand satisfaction.
Go eat some comfort food. You need it.
Has anyone received an iMac with no screen issues?
I'm returning my iMac for a refund and will continue to do so until I get one that works or decide to get a NEW MacBook Pro or Mac Pro whenever they are released.
Do I have any chance of buying a new iMac with a perfect screen?

Mate, your screen looks like a Final Cut Studio box.
Thanks for giving me a laugh through all the pain
I'm about to call Apple about my #1 iMac #1 replaced but still yellow display.. wish me luck people!
YOU. KNOW. WHAT. Today I had a bit of free time after my lecture and decided to go check out the Apple store at my uni. I saw their 27" demo and guess what???????
No yellow tint AT ALL, uniform white is displayed across the entire screen. Back lighting is also even lit. There is a very feint grey band that runs horizontally towards the bottom just like my previous two units, but I really think it's tolerable as it's hardly noticeable -- only when looking closely. They don't allow taking photos in their store so unfortunately I can't show it to you guys.
It is a week 48 from last year, with a C2D processor. They said they've got stock for 6 computers and I believe they're from the same batch. Problem-free iMacs up for grabs at UQ!
So I guess I should've visited the store earlier. Oh well. Back to uni iPod rebate runs till next week if anyone in Oz is still interested.
I've actually only seen *one* perfect 27" iMac and that was a week 41 display unit, which was one of the first produced. Every other new iMac I've looked at (had two myself and seen quite a few at the Apple Store and other retailers) all had some degree of tint variability across the screen--all immediately noticeable on a white background. This problem is pretty endemic to the new LED backlighting system that Apple has implemented on the 21.5" and 27" iMacs.
The stark differences in the color temperature across the screen from cooler (blue) to warmer (yellow) may be due to the individual LEDs themselves, changes in color due to thermal properties, or an irregular layout of the diffuser sheets behind the LCD panel (or all of these issues). Since all previous iMacs used CCFL backlighting, and MacBooks have edge LED backlights, this issue is particular to these iMac systems as Apple has implemented a patented "LED tile" system for these larger screens. As I inferred in this thread, since this is a problem with Apple's backlight design, it more than likely will be around until they do a redesign of the iMac.
It's scary to think that they'll never figure this out and I'll be doomed for life.
I want to go to an Apple Store and see one before I buy but I don't think they'll ever have a 2TB in stock.
I would chalk this up to the fact that the iMacs are all tilted up at the Apple stores, combined with the very bright lighting and reflective screens, and you have masked the issue. They all 'appear' perfect at my local store also.
Regarding to my earlier post, I called Apple Technical Support, who has been working on my case, and asked to look at the screen pictures I emailed him before starting our conversation
.
He knew that I'm a Software Engineer working as an iPhone and iPad developer so he knew he better not lie to me.
He told me that it was unacceptable for the yellow issue and uneven color displayed on the iMac screen. But the back-light bleeding issue is pretty normal and acceptable in my case ???
What you guys think for my screen regarding to back-light bleeding shown below (also yellow issue) Do you agree with his opinion?

These iMacs are here to stay. You either live with it or return it. Nothing is gonna change. They ALL have varying degrees of yellow tint.
POLL Manipulation??
It seems that the poll used to indicate 355 yellow screens and now its lower at 345. I wonder why that number decreased.

Anyone here own an LCD television? I'd venture to say not, as there is NO such thing as a perfect LCD television, especially when you get beyond 40". Samsung, Sony, etc., all state that there are variations in LCD panels, and in terms of light bleeding or 'clouding', basically don't expect it to be perfect. Those manufacturers will exchange once maybe twice, and that's ONLY if it is extremely bad and is causing a problem. More than that and they will tell you to piss off. Same thing with even the great Amazon.com. And again, there is a reason for that of which all of the perfectionist "my screen has a slight tinge of blue in the second half of the right angle of the screen seen only in darkness after I keep a black background on for 3 days" crowd, would turn any company bankrupt if they had their way. I'm pleased that Apple is addressing this with such a lenient return/exchange policy, but some are just blatantly taking advantage of the situation.
As I've said before, if you truly have a yellowing issue that I've seen some have on here, then by all means, get it swapped out. But for the "can you tell me if my screen is faulty or yellow" crowd..give me a break. If you need the forum to tell you that your screen is unacceptable, then you should just get an emachine and CRT and call it a day.

I own a 40" Samsung 630B and its not perfect, but its a hell of a lot better than this 27 inch in front of me that cost almost twice as much.
Honestly, I don't need perfect, but I don't expect sub 200 dollar LCD TN quality either (okay, so its still nicer than TN, but my TN doesnt have yellow and nearly as much backlight bleed).
Either way, I know what you are saying. I am not saying you are wrong, however there is a limit to what is and is not acceptable. Especially in this price range.
Also, I agree with this:
No way, our Apple store was an authorised reseller (Next Byte) and since they only/mainly sell to uni students and staff, the store doesn't look as shiny as the proper stores. It's basically a 10x10m floor size located at some corner. Lighting is pretty standard, no bright lights, just 2 fluorescent lights.
Yes the screen is tilted upwards moving it and looking up and down and view from all possible angles, I do not see any yellowing though the only down side is the slight grey bar at the bottom of the screen. I guess it's because of them being early stock (week 48), but can't say for sure.
I agree with people saying you wont get a perfect screen so deal with it. But it does dramatically effect some peopls work.
If you do a lot of image editing where colour matching must be perfect you will find you will start to put a magenta cast to the bottom of your images to compensate for the yellow tint.
Imagine sending a client a DVD of their work only to find the colours are WRONG.

I'm getting one of the Sydney store managers to call me tomorrow regarding the yellowing issue, and the fact that it took me 3 computers to get what I considered acceptable/ By acceptable, I'm saying this one has slight yellowing but it doesn't bother me. I'll post back when I (hopefully) hear from them tomorrow.
I think if you earn your living as a graphic designer, I'm not sure why you would be using an LCD in the first place? Just from a backlighting issue in itself, color uniformity on the grey scale would be off in certain areas of the screen.
In terms of photography and image processing, the issue is virtually non-existent, unless you have an incredibly faulty screen.
I've received 2 faulty units already and a third one is being sent from Shanghai today. I've got a personal email (not one of those generic ones) telling me that they're sorry for the inconvenience and provided a tracking number. I could say Apple's customer service is impeccable, though you still get one or two sceptics from the call centres wanting you to buy AppleCare instead.
The ones I've been put through from the US call centres (dialled from Australia) are in Singapore (probably servicing the Asia-Pacific region), and they are really helpful.
Anyway I looked up TNT's site and for a non-contract shipment of a 27" iMac would cost AUD$380-$420 for such weight and size. Of course what Apple's paying is considerably lower than that but everytime they send out new units as replacements it's been hitting them back.
A few pages back of this tread someone mentioned "apparently" it is still cheaper to do this then to address the whole issue fundamentally from the beginning, i.e. design.
Of course the consumers (i.e. you and I) want a decent display since we are paying so much for these computers. But what defines "decent" is really different from user to user, and might not pair up with "acceptable threshold" as some people have mentioned here as well.
There has been some comments out there saying people are abusing the return/replacement system and some even try to justify that the yellowing issue is not a problem for some types of usage that would obviously be compromised. I think one really needs to be in the position of doing such work to be able to say that, otherwise one would be making assumptions thinking the issue is virtually non-existent.
It also doesn't help saying if you're gonna be using it mainly for graphic designing, don't get the iMac at all or get a different computer with a different screen. It might be the user that wants an iMac. If they need or want to run OS X, there are really no other similar models comparable to the iMac. A MBP + screen? A Mac Pro? == unlimited budget or other limiting factors?
For those types of people that don't really have a choice, when especially they are doing work (academic, work/job or otherwise) on the iMacs. They can only send them back for replacements. At least in some parts of the world the waiting time is not long or get to keep using the 1st unit until the 2nd comes. Otherwise they could still do work e.g. on an old MacBook but that's not really productive is it? (but as productive as on a defective screen?) In those situations if both the fault and the circumstances are justifiable then there's absolutely no reason to say sending those units back is unreasonable or abusive.
So in any case let's try not to make assumptions about the screen severity only by judging the photos, or how tolerable to their intended usage would be. The photos were originally (on page 1) used as proofs to show defective units and not to proof the reverse or be over-critical by others that the screen is tolerable and then have everyone geed up.
Some food for thought today good for the weekend.
Apple have set up a replacement for my 5th machine. This time they have decided to do it as a custom build from China. The Apple rep seems to think there are obviously a lot of bad batches sitting around pre-made in warehouses.
He says all the new machine don't have this problem so he has got me one built directly from China using all new parts.
Should be here in a few days so fingers crossed.

Sorry, but you are wrong to say ALL. It took me four tries but I did get a good one. My 25% success rate won't exactly set people's minds at ease, but it's not 0%.
Are you joking? I'm pretty sure a few of the people here own LCD TVs, including me.
No, LCD TVs are not perfect. But the three bad iMacs I went through to get a good one looked nothing like my twos LCD TVs, nothing like the LCD screen on my MBP, nothing like the LCD screen on my ACD, nothing like the LCD on my Wife's laptop, nothing like the LCD on my iPhone, nothing like the LCD screen I used at work, nothing like the cheapo 14" LCD screen I bought years ago, etc.
I know that there are people who will stare at a perfectly good iMac for hours and take underexposed pictures in an effort to find and exagerate perfectly normal uneveness.
But the yellow tint problem is real and has affected many, many people.
I think the big difference is that a typical 40"+ LCD television is meant to be viewed from across the room (I sit on the couch at least 20 feet from my 46" set) displaying primarily video content, whereas a computer screen is used at close distance with mostly static images making it far easier to notice flaws. White backgrounds, which pop up on virtually every other website, make it almost impossible to ignore an iMac with this issue, which is not comparable to the light bleeding or clouding present on other LCD panels.
I agree that the if you need the "grey bars test" or some other mechanism to know that you have some tint variability, then you might have an somewhat decent screen. Both of my iMacs were obviously unacceptable to me just based on a few minutes of use.
