Thanks for the opinion. I must mention, however, I'm not concerned to much about overall colour of the screen, but inconsistency in certain areas.

Mine just arrived, having shipped a week early (so only one week delay). I don't believe mine has the yellow tinge (Week 07 of 2010 if I am reading the code right - W8007), but if it does, it is so subtle as to be almost subjective in the far right corner so I voted "good" because to be honest, it might be something I think I see because I expect to see it.
My week 6 machine arrived yesterday - real sexy bit of kit......
...except my screen has such a yellow tinge I could see it while on the initial white booting up screen.... along with 1 dead pixel!!!
Not happy, mostly coz I will have to wait an age assuming Apple will replace it with a new one.
Does anyone have experience of getting replacements for yellow tinge on models ordered online? Will Apple ship out a new one, and collect the old one at the same time as delivery, or how does it work?

The first one looks better, but have you tried calibrating both screens? It looks like the first is a bit too blue-ish and the second a bit too yellow.
Hi people, I have a 21.5 iMac that I bought 3 weeks ago, it's my first Mac and I think both SO & Hardware are excellent and hi-end stuff, but when I first read about this issue I got worried, well this is my screen:
can you see if I'm experiencing this issue?, the photo was taken at the minimun brightness level in the dark
the computer is from the batch number 50, no flicker, no dead pixs, thx!

panel on my 4th iMac... This was suppose to be the "fix"...
You decide:
Why the thumbs down? That is possibly the BEST one anyone has posted. Seriously, keep it. It's never going to be 101% perfect. that's nearly 100%. KEEP IT as far as the yellow is concerned. How is the backlight bleed? Could you take a picture of that? (black screen, brightness up, room lighting dark)

I think if you need to ask other people if your screen is good then your screen is good. Ask yourself, does it look yellow? does it bother me? if you answer no, then that should be the end of it.. I mean this in the friendliest way possible.

You decide:
The pictures are of zero value I'm afraid. Look at both the top gray bars in the last image. Both are far darker on their individual left sides than their right sides. This shows the images to be worthless. Depending on whatever section of either bar is selected for comparison, a different result is guaranteed. Indeed, the range of tone variation across just the top left gray bar is greater than the apparent variation between top and bottom.
Can you post another pic, shot from across the room? As are from the mac as you can get. The reason I say that is because there are two kinds of yellow tint -- (1) an even gradation from from white to yellow, top to bottom, that is dependent on the viewing angle; and (2) blotchy yellow patches or "stains" throughout the display. (1) is visible, e.g., when your eyes are at mid screen height and you look down to the bottom of the screen. However, if you move your head & eyes down to the level of the bottom of the screen, the yellow goes away. (2) on the other had is visible from any angle.
I do see that the bottom is a little yellower than the top. But I can't see blotchiness in your photos, so maybe you only have (1) -- or maybe I just can't see the blotchiness in the photo.
At any rate, IMHO (1) is not a flaw but (2) is. I guess opinions might vary, but I think (1) is not a flaw because a lot of LCD panels have issues with viewing angles -- many much more pronounced that the iMac.)
I think you need glasses.....
or your iMac is hosed... Please cease to comment on any of my posts.
The first picture and the last picture were taken from the exact same angle on a tripod w/o moving the camera or the iMac... so if the last image is showing a degree of tone, then the first image would too. We are simply looking at the "yellow" or "gradiation" from the top to the bottom or the left to the right.
Thanks and have a nice day.

I will try...
to set the camera up back on the tripod and get shots dead on from heights that correspond to the bottom, middle, and top part of the screen. I typically "move" my head up/down/left/right with looking at/for this yellowing. It's clearly there... I think we've established there is an "anomaly" in these displays...

The imac screen is so big you are going too see yellow from different angles especially tilted. But some look BAD in the photo's?
The almost TN quality to the screen is the way the screen technology has gone unfortunately! (At least from LG anyway!)
I have a macbook air, 24" imac, 24" LED and trust me, perfect screens from apple are a rarity on most product lines or seem to be a work in progress!
PS I didn't think I had a problem with my screen until you guys pointed it out!

That's fine. Not saying you don't have a problem -- just that I couldn't tell from those photos. Since you see the yellow regardless of your head height, it sounds like you have yellow tinge "type 2".

Man...this is simply NOT true. People have gotten 30" monitors with no yellow! It has NOTHING to do with the size, or angles (don't you know the strength of IPS is color uniformity from pretty much all angles?) and EVERYTHING to do with the fact that the screens absolutely suck.
People need to stop putting up with getting sub par gear from Apple. The screens are broken, end of story. There are certain posters who basically like to blame everyone except Apple on this issue. As if the users are idiots whose eyes are less useful than the power of suggestion. I had two iMac's. I really wanted to keep them. There is no way I possibly could have as a person with at least a little self respect. I am not going to let a company like Apple essentially steal 2000 dollars from me for junk hardware. I would suggest others do the same. If you have to convince yourself it's what you want, then there is a huge huge problem. Like that guy saying to keep the machine above. That is positively one of the worst monitors I have ever seen in my life! That machine should be returned to Apple immediately.
p.s. to fanboys. The Dell u2711's have hit the streets, and there are PICKY PC users saying they look absolutely incredible. You know, the monitors that use the exact same panel as the iMac. If the panels were at fault, these guys would be all over it, especially since they knew beforehand of the problems facing the Imac's. No one wants a partially yellow screen.
It's the iMac's and Apple people! So positively absurd...
I take it you're not one of those PICKY PC users or else you'd surely know that while the panel of the U2711 may or may not be the same as the one in the iMac it has entirely different backlighting (CCFL as opposed to LED).
But anyway, it is quite interesting that you are using the Dell as some sort of evidence for negligence on Apple's part. Whether or not the panel's are identical they are both made by the same manufacturer, the number two manufacturer of LCD panels in the world, LG Display.
Apple doesn't make LCD panels. I'm sure they're going straight back to LG with this yellow tinge problem. Yes, I understand and agree it is 100% Apple's responsibility to see that the problem is resolved, obviously.
The U2711 looks really really nice, by the way. I'm thinking I want to get one for a homemade PC in the future.

I would say it has a little yellow tinge at the bottom of the screen. Not much though, I've seen pictures of screens far worse.

I couldn't agree more! Really, who cares what other people think? You're the one who's going to be looking at it.
The power of suggestion can be a dangerous thing.
More photos
So I took more photos of my screen on a tripod and raised/lowered the camera to take photos with it on a plane with the bottom, middle, and top part of the screen, so see if that made a difference. Photos are cropped to only show the screen.
to me, it still appears I have a problem:
Camera on the top third plane:
Camera on center:
Camera on bottom third plane:
Crop of top/bottom bar together using the picture with camera on the bottom third plane:
Not sure about anyone else... but regardless of what plane the camera is on, there is a gradation here... whether or not it's "standard" and within specs is beyond me... but it's there. It also appears to go from left to right and top to bottom... who knows... this is driving me nuts.

If it doesn't deliver (next week I expect the delivery of a i5) what they advertise with or what you would expect from such kind of technology, it will be full refund and a formal complaint with the local advertisement watchdog. I will not go through a lottery of replacements.
Yesterday I was with a friend who has a new LED based IPS screen (although smaller) and I scrutinized the screen for uneven problems. There where zero problems which isn't abnormal for a LED based screen as that is one of the main reasons we have the technology in the first place.
I love my current mac but what I really hate is the "gradient" problem so something purple suddenly becomes pink at the bottom. What sucks the most is that a frikking cheapass low end samsung monitor doesn't have any color uniformity problems*.
* uniformity of colors != perfect gamut , calibrated colors, Adobe RGB support or other features what you can expect from professional EIZO monitors... .
Ok, I just was looking for someone who confirms what I suspected, it has a little yellow tinge at the bottom, but since I'm a software developer it doesn't bother me enough to go back to the store for a replacement, but if this issue worsens I will do it, I know how annoying it can be for a person who retouches photos and design,
Thx!
