czachorski , Yes I agree that may be those complaints don't represent the majority , but what I can see from looking at the numerous World Wide forums, is there are more and more daily complaints being made by separate posters , and the numbers are increasing at an alarming rate .
Got a tip for us?

New 24" Penryn iMac owners....screen bleed fixed???

I was actually thinking about the same.
A display is framed,what if the frame is too tight in places.
If you ever touched a laptop display You know when you touch it there are bright spots on the display.
So,it might just be that the metal display frame is mounted too tight!
But.if thats the case it could be easily fixed by Apple,or not?
Improper pressure between the panel and the liquid crystals could cause a mura effect but would have occured when the panel was sealed at the factory and not from anything Apple does with their mounting of it in the case.
You can see from these disassembly photos that there is nothing on top of the LCD other than a protective rubber strip around the edges and the glass panel.
A little confused
I have been reading this thread and went to the local Apple retail store yesterday. I looked at 5 different 24" Penryn iMacs, checking photographs and video and I could detect no flaws in any of the displays. I suppose they could hand pick the ones for the store, but is that practical? I was standing right in front of the display; does the problem only show up at an angle? I also tried some photographs (From the Astronomy picture of the day - which has lots of black areas) and couldn't tell any problem, either on the 24" or the 20". I'm looking to buy a new 24" and I would like to know how to tell if it has a problem with the display.
Our local Council on Aging also has a 24" iMac (pre-Penryn) and I have spent hours on it and can't see any flaws on the display.
What am I missing?

If your in a brightly lit room bleed is harder (though not impossible) to detect. Its painfully easy to see in a dimly lit room on a dark screen. Bars on a film...dark wall paper etc. The gradient show up well on a grey screen and the yellowing on the right shows up on a white screen. There are a few flaws on these screens that show up on different backgrounds at different times.
It's interesting, because there has been an increase in the last week, but I would hardly describe it as an "alarming rate" with such drama.
It's the bump in discussions surrounding the iMac update. Prior to the refresh last week, the rate of discussions on the iMac screens topic died off around here, to the point of almost no new posts of issues for weeks at a time. In the past week, there has been more activity around here on this issue than in the previous 3 months. I suspect that is what you are picking up on, and the action around here will slow with time again shortly once the iMac refresh becomes old news again.I think what star555 commented on is totally true, I live in Asia and have both German and Spanish friends who are mac users , they have confirmed that even on their Language Apple Help web sites the number of postings about the iMac screen problems have gone up, and continue to go up.. may be the amount of people who post their screen problems here on this English language forum are only the tip of an ice berg , and us English language forum users are not totally seeing the whole picture in the rest of the non speaking apple mac world
Right, the exact same LG-Philips H-IPS panel that is in the mid-2007 24" iMac. I think it would have come out by now if there were any changes there.
Yeah, thanks for running that command at the Apple Store. I would have been very surprised if they had changed parts but its good to have positive confirmation anyway.

There is another thing that has gone up, and continues to go up too: the number of iMacs Apple is selling. Do you think these to obervations could be related? No, couldn't be.....
So, if Apple was really smart, they'd switch to crappy TN
panels in the 24" iMacs and ACDs, too. ...huh?
You can fool some of the people all of the time, and all of
the people some of the time...
...and that's good enough to generate huge profits,

No, just the 20-inchers, as they have done. That is the place where the target market is more focused on price than quality. The 24" is there appeal to exactly the people complaining in this thread.
Onsite Technician with Apple Care?
so i called apple about my gradient problem on my brand new 24" iMac. apparently technicians will come to your home (if you like within 50 miles of The Apple Store) if you have Apple Care.
has anyone had an Apple technician go to their house about fixing the screen? can they fix the screen at my home? would they just come to evaluate it, see the gradient, and then come back again with a replacement? a replacement iMac i've been reading that could be just as bad if not worse, plus i'm assuming i'd have to reinstall everything once again...
any thoughts?

I've had a new 24" 3.06ghz iMac in my home this weekend and the screen is outstanding. Because of comments here, I've checked particularly closely for uneven lighting etc on dark gray, flat colored backgrounds and I see no issues whatsoever. In some ways, I prefer this to my 23" Apple Cinema Display, as it has none of the (very slight) graininess I perceive in the ACD. But this is most likely more of a gloss v matte thing, rather than a quality issue.
If this iMac had an input that would allow it to be used as a monitor for my laptop, I doubt I'd feel the need for an ACD the iMac screen quality looks that good to me.
The profile says this is a 9C8D screen, whatever that might be. I suppose someone will now tell me that this is one of the less-favored screens and that I shouldn't be liking it

This post had me quite worried as i'd just ordered a shiny new iMac. But, after having my new computer for 3 hours (it came 2 days early!) i can say that none of these issues present a noticeable problem for me. although i'm no expert, i do use my computers an awful lot and i can say that this screen is no worse than any i have used. my advice to those contemplating a purchase, absolutely get it if you are a home/small business user perhaps a different story if you are an intense video or photo editor...but i have no licence to opinion there. If there is a small problem with my screen, as one reply said i will not go looking for it because it will probably spoil my enjoyment of using it.

Hi czachorski , I think you have a valid point , The numbers of iMac's being bought continues to go up as you say, but could it not be that the real reason the numbers of people complaining World Wide is going up on a daily basis .... is just that .. The numbers of people who are buying an iMac and then finding it has he screen display problem is going up ..... because MORE people are buying them .
yesterday i went to the apple store in Rome with my 3.06 iMac.
i explained the problem to a genius, he changed the machine with a brand new one. same problem, less evident but still present.
i checked the 4 iMac 24' in the store, all have the same problem.
the replace that the apple give to me was slighty better, so i decided to hold it and close on eye every time i look a white page in the broswer.
i'm sad...an almost perfect machine with this problem.

Just had to quote these two posts. There are good units out there. I suspect their in the vast majority.

Oh, most definitely. I think if I am comprehending you, that was my point. There is a certain frequency rate of people who are going to be sensitive to these issues. If that frequency rate stays the same, as Apple sells more iMacs, then of course, you will get more complaints.
After 15.....yes 15 units! I can say without a shadow of a doubt that ALL the 24" iMacs have these screen issues. The units I have had have all been manufactured this year and came from the Czech Republic (VM) and China (W) weeks of manufacture were 5/9/12/14/16. All had bleed, some worse than others but all clearly visable on a dark screen in a dimly lit room. All had the gradient issue. Two units had dead pixels and two had dust trapped between the glass and screen and backlight and screen. One unit had a nasty ding in the side of the case and another a mouse that jumped all over the screen. The first 3.06GHz I had had a loud inverter buzz that got louder the higher i adjusted the brightness. I have only had to take one product back very occasionally with other manufacturers technolgy. I find it very depressing that Apple is happy to send out such sub-par hardware with a variety of QC issues. I don't want a bland black plastic box running Vista, I want a stylish all in one running a deccent OS so really have no alternative hence trying sooo many units. As I have said in previous threads on other forums on this issue, I LOVE APPLE STUFF! I have loads of it......pretty much every ipod.....a 20" core2duo imac.....apple TV......iphone etc etc etc. I am not here to bash apple but to say what a shame it is that the quality of there goods in my repeated experiance seems to be in decline.
Why did you stop at 15? The 24" iMac I have here has a terrific, evenly lit screen. And no buzzes, jumping mice or dings. Maybe only one in every sixteen is good.
