I think I'm seeing some yellow, low corners.
Anyone see it?
Haha - I've never seen a camera spit out a file called "Screenshot2010-03-07at111951AM.png" but I have seen these using built in screen shots in OS X.
Yeah, I think I see some yellowing on that screen shot! LOL!
If you take a screen shot you will get a perfect image every time. You have to take a photo of the screen...this has been said I think 1000 times in this forum.
I just had my screen replaced. I'm very happy with it.
clearly another screen shot. but I'm glad you are happy with your new screen.
Definitely yellow across the entire bottom horizon. Concentrated on the middle and on the right.
What week?
Mine looked similar. Except I had yellow right up the center.
I only noticed it on white backgrounds and especially when folder windows were open, and that was too frustrating to keep.
I had it for 3 days.
My replacement should arrive tomorrow.
I really hope it will be a keeper.
I just got it this past week, ordered the Friday before.
To be honest, if It wasn't for the threads here I doubt I'd ever notice it.
SO what happens, send it back or keep it? If sent back, does begging for upgrades work

I don't see an issue with your screen, screenshot or otherwise. For some, they will ALWAYS see some kind of imperfection with the LCD, therefore, creating a problem for those that would have never seen it in the first place.
Try this stuff with television LCD panels, and after the first time, maybe two, they will tell you to jump in the lake.
If you are looking for perfection with any LCD panel, you are not going to find it, no matter how much you pay.
Ummm...everyone is entitled to a perfect LCD. Why try convince someone that a subpar screen is acceptable.
That screen is obviously flawed and it needs to be replaced. A person must be color blind not to see the yellowing at the bottom.
And yes there is a perfect LCD. You just have to ask for it.

That is yellow (color is NOT uniform from that screen), I have seen people with much lesser yellowing than that.
Mine was fine when watching a movie, etc, I didn't see prominent yellow.
Except it was there just browsing around and working on my computer and it bugged the heck out of me.
I actually posted on the forum in the "I just got a new mac - Perfect" thread five minutes after turning it on (week 8).
Even in my elated post, I remarked I saw some yellow, but it wasn't so bad, but it bothered me the more I used the machine. I saw it immediately on the startup screen.
My advice:
If you don't notice that its "there" so to speak. KEEP IT.
If you are upset that you paid between $2,000 - $3,000 for a yellowish screen from Apple (which prides themselves on being an industry standard for filmmakers and many photographers, printmakers, etc.) then do something about it.
People saying there is no such thing as a perfect LCD have a poor argument to prove their point. I would say the majority of Apple's iMac are most probably "perfect" or "near perfect" in regards to screen quality/resolution/color. I have had a Sony LCD monitor for 7 years, and I would say its pretty perfect apart from a single stuck pixel.
You can buy a 50" LCD TV and probably find a "perfect" one that doesn't have issues.
Maybe its the IPS backlit technology that has issues, or maybe its this specific product that is susceptible to slight shifts in color uniformity.
For filmmakers/animators/photographers, correcting for these "slight shifts" can be the wrong thing to do because your screen is faulty, not your work. When that work is projected/exhibited/printed in a large format, whatever "correction" you did to an area that did not look uniform will show itself to you tenfold and that can be a huge problem. (Granted this is an extreme example, but a very plausible one at that).
Apple has finally acknowledged a problem.
Don't let a huge company discourage you from saying something negative about their product. They will take action on your behalf IF you ask it of them.
Good luck.
I've modified my post with no saturations pictures. I'ts better to compare I agree.
I'm on my 2nd iMac i7, it was delivered to me last friday. It's a week 10 model. How would you qualify this screen based attached photo? Brightness was at 50%, photo is unedited except cropped. Photo was taken with a dslr.
Thanks.

Yes, I do: right and left lower half of screen, middle is ok. I'm not sure whether it's within acceptable limits, or whether I should return it and hope for a better one. In other words: does it get any better than this? Are there any people with more uniformly colored screens?
iMac went in last week for a 2nd screen after the first replacement came back worse than before. The repair agents say there's nothing wrong with it so can't replace the screen, I have to take it back and accept it as is.
What's strange is that they replaced it first time round and the problem wasn't as bad, so I've no idea what's going on. They've also said there's another iMac in there and the screen on that one is worse than mine, so maybe that's what they're using as a benchmark.
Very strange as Apple said they would put notes on the fault reference to say they wanted to replace the screen again before considering a refund or replacement.
Maybe they're instructing their repair centres to be more strict on what counts as being a "faulty" screen to cut down on the amount of replacements they're doing?

Picked it up, back home, switched it on. Got the test image up, problem is obviously still there. Put a recent snowy picture on screen, called my mate over from next door and asked him to have a look without telling him what he was looking for.
"The bottom of the screen is yellowy".
At least I'm not imagining it! Not sure what to do now.

Just received a week 9 27-inch iMac and the bottom of the screen is yellow.
However, I only noticed it when doing the test and other than that the iMac is perfect. Should I risk sending iMac's back and forth over this or keep the machine?

I got a week 9 model more than a week ago (also in NL), I sent it back because there was a very noticeable yellow spot on the right bottom.
My second iMac (week 10), which I received last friday, is much better but still yellowish on the lower part of the screen, mostly on the right and a bit less on the left side (see pic in my post above).
I'm also considering sending it back again, but as you, I'm afraid of getting another one back just like this, or worse. Maybe it's just the way it is?
If these pictures are not saturated, then you have quite a lot yellow tinge I would say.
Just by looking at the photo I suspect little more yellow in lower right corner. By bumping up the saturation of the image I confirm my feeling. Hard to tell if it worth keeping it. Your next one might be better, or not... I'm on my 4th iMac now and I'm taking it to Apple store tomorrow for Genius appointment. If they can't fix it = refund. :-(
Good luck,
K
I agree. I would return it if i'd be sure to get a better one, but that's hard to tell. For the rest it's a very good machine and I really enjoy working on it, would be a shame to loose it.
That's frustrating. Let's hope they can solve it once and for all. Keep us posted and good luck!
So, got my iMac21" back from Official Apple Service Partner.
As mentioned, he has been very helpfull and tried 3 different panels. The Last one has only a very light shadow at the bottom if the screen (where the dock usually is) and a hardly noticeable 3cm long yelowish-darker shadow at the left and right lower side of the screen. So I can hardly spot any yellowing in the "typical" areas (there might be, but we always said, we would settle with a "good" panel, since there will never be a "perfect" panel, we said so, didn't we?), only those shadows.
If it where like that in the first place, I would have never noticed a problem.
But it makes the loudest screen noise I ever heard! From Bootscreen on - the brighter the louder (not typical for our problem!). I thought I had the noise problem before, I surely got it now. You really honestly can't stand it. It's about half the loudness of an alarm clock.
So I called Apple Care the moment I came home with the machine. They escalated to 2nd-level technician. Who politely offered me a "pick-up" service (I told him I was tired of driving 45km several times to see yellow panels and now get screemed at by my own computer). This way, the mac would go to another service company (their own?). Maybe the (also exchanged) LED dimmer board got damaged while fitting all those panels in my machine...
Hooray for the pick-up. But alas for another 1-2 weeks without my computer. I actually did buy it for it to sit on my desk!

Again, there is no such thing as a perfect LCD. Anything that is backlit on a large surface will never reach 100% uniformity in color or light bleeding. Even the new LED television products have challenges with this.
No one is saying take something that you are not happy with. What I am saying is that this forum, and others like it, can create an issue that a purchaser may not have seen in the first place. Perfect example is that of DLP televisions. I'd never seen the 'rainbow effect' until it was pointed out to me in the AVSforum. After that, saw it every time and had to take the television back. I would have never seen it unless someone had pointed it out. Same thing here with the 'yellow' screens, unless it is blatently obvious.
The message in this forum regarding this topic as been this..."Sit in a completely dark room, turn the brightness down on the monitor, and take a picture of your screen. Not a screen shot, but a real picture. If you don't see anything with the lights on, you're not doing something right. Let's play with the settings and method until we make something undesireable happen."
