Those numbers can't be even close to correct. At worse it's 40% of MRF users that have bothered to even go through the process of the yellow tint test etc....

Whats the % of iMac owners in the world that even visit MRF? I'm guessing it's fairly small.

You really shouldn't be telling people numbers like that in a way that makes it look like 40% of iMac owners with 21.5 inch screens have yellow issues, because it just isn't true.

I agree the figure is likely nearer 80%
 
I'm a professional photographer and work with solid displays every working day of my life, all day.

I know when a screen is not right so will be completely ignoring your view. Think what you like, I'm telling you I've had three defective screens and I assure you I know what I'm talking about.

nail on the head....

most customers will have a yellow screen but not notice it or believe its a feature...

does that make it right in a silly priced computer?

No way.
 
Ha ha....looks like I hit a little close to home with you! Don't worry, I don't think you're a bad person....if you want internet attention there's nothing wrong with that.

Relax and enjoy your Internet forum experience.

You are an a$$.

You are the troll who needs the attention. I just shelled out over $2K for something that looks like crap.

I just left Fedex and I hope the replacement is better.

Do you honestly not see an issue with the display?

rubbish...

ignorance counts for most of the ignores... in fact I don't think I've seen a genuine non yellow iMac...anywhere.


...sure you have -- PRIOR to 2009 ! :)

To be fair, it seems to me that Apple has made at least one (and probably several) attempts to fix this issue- at least for the 27".

...and I think they WILL get better, and eventually this problem (like antennagate) will go away. But for now, it sucks man.

Yellow screen test????

If my wife passes her new "to be delivered tomorrow" iMac with her own "2 x thumbs up", then we keep it. If she says the screen looks weird (as in NOT normal), then the iMac goes back. That's the only test I need to apply to our future iMac. :eek:

Seriously...

If one is NOT satisfied with any product, they should have the legal and ethical right to return it. Return it until an acceptable replacement is provided. Or, the 3 x strikes rule is applied. re: After 3 returns, it's the buyer's choice if they want a full refund or they try replacing the product a few more times. This is how I hope it would work - when a defictive product is obtained...

Honestly? I have no idea what you are on about? looks like a regular screen shot to me.
 
Lol ....

If I was using it for casual work then it would be easy to attempt it and live with some exchanges but I need color accuracy for the type of work I do.

......

Seriously, have a look at some of the NEC, EIZO, or LaCie monitors. Entry level is not THAT expensive. Drive it with MBP (you really don't need Mac Pro!) and you are all set. Overall slightly more expensive and not as good looking (although it is question of taste), but doing better job.

I went around the 21" imac's today at my local apple store and found that ALL, yes ALL of them have a yellow tint, getting yellower as it approaches the bottom right corner (the gradient is the bigger issue).

I bought an imac yesterday, went to the bar today and the genius replaced the imac with a new one out of the box, but the screen exhibited the same problem. Right now, they are replacing the screen, if it still has the yellowing, I am returning it. (I don't know why I am trying when all the lcd's have the problem.

If this wasn't a real problem, apple wouldn't have replace it.

I got one without any yellow but it still has the gray shadow on the bottom. It is my 4th one and whoever is saying people are just looking for attention is an idiot apple pretty much admitted there was a problem earlier in the year. Maybe the updated ones are a little better but I still think it is at least a 50/50 chance of getting a screen that is obviously pretty yellow.

I think most people just do not notice because the aren't looking for it and most people don't do professional photography. I guarantee my mom wouldn't have noticed anything was wrong with any of mine but if your the techy type you will notice it if it is there especially if you are looking for the yellow.

Bottom line I guarantee it is a very low percentage of perfect screens but apple is good about returning them and you have a really good chance of getting an acceptable one if you are will to take the chance of having to return a few.
 
Folks, don't sweat it. Btom, archipellago, tennisnmusic, and a few others have been bashing the iMac and the yellow screen issue for the last 10 months.

They all point to the poll as if it's a scientific certainty and claim things like "it's the only poll we have, so it must be true and we have to believe it". Many people have tried to explain how results are skewed in a poll like that, but the bashers do not have the cognitive ability to understand why. It's not their fault. Simply put, some people just don't have the brain power to comprehend and understand these things.

Have there been a few bad screens? Certainly. And Apple bends over backwards to make sure every one of their customers are satisfied.

Have the percentages of bad screens been in the double digits? Absolutely not. If it were that bad, you'd be hearing about it in a bajillion news stories and blogs.

It's as simple as that.

No offense....but I highly doubt that you've gotten 3 defective screens from Apple. A company with the quality reputation of Apple would never have such high % of quality control problems.

LMFAO! What rock have you been hiding under?

To the OP:

The iMacs have issues with the LED screens. Some people claim perfect screens. In my personal experience. I went through 3, i7 iMacs when they first came out about six months ago. They ALL had yellowing along the bottom right. I looked at numerous iMacs at brick and mortar stores, all had yellowing. I decided to hold off and about three weeks ago ordered another 27" iMac again. The screen had no yellowing but had a dark band across the bottom. I returned it and received a "refresh" i7 that has yellowing along the bottom left AND a dark band along the bottom.

At this point I am giving up on the iMacs until the LED screen tech is different. In my opinion, the Apples LED technology is flawed.

HERE is their patent on LED backlighting. I especially like these quotes:

Another challenge with utilizing LEDs in large arrays is maintaining uniformity of color in the large numbers of LEDs. The color balance and spectra of the LEDs is limited by the phosphorescence. For example, white LEDs are often actually blue LEDs with a complementary phosphor (yellow) dot on the front of the LED. Depending upon manufacturing precision (and thus, related manufacturing costs), actual colors may vary from, for example, slightly blue to slightly pink. Understandably, reducing or compensating for such variability increases cost and complexity significantly as the number of LEDs increases in larger display configurations and environments.
The color and the output of each LED also depend fairly sensitively on temperature. The difficulties in providing proper thermal management capability can readily lead to temperature variations across the distributed array of LED light sources. Since the color qualities of LED light sources are sensitively dependent upon their operating temperatures, such non-uniformities lead to unacceptable variations in color from one portion of the display to another.

So the whites aren't white. They are bluish or yellow. Otherwise its a great machine.

There was a bunch of news stories earlier this year. Go check out gizmodo's posts tagged with "yellow screen saga". It was a huge problem back then and it is probably better now but the percentage with yellow tinge is easily in the double digits either way.

I can assure you I'm not an internet attention seeker.

Since the July re-fresh I have had 3 iMacs and all have had the yellow tinge issue. Working with alot of white background photography, its simply un-workable for me and I have decided to just get a refund now.

I might go into a store to see if I can test the screen before buying but may just have to look elsewhere now unfortunately. A shame because I really wanted to work with this iMac but I just may have been very unlucky.

I think most general user's wont notice and there will be many machines without the issue but it's not like we're making it up. For a machine that starts at £999 and boasts about its display, there shouldn't be this many reports of problems.

your calibrating your monitor right? Setting the white point is a good thing to do. Something like 6550K will produce a slightly yellow cast. People who output to a hard copy use this setting because it better represents the printed page.

Im sure apple would of checked that for you though. You can find the Monitor Calibration tool in the System Preferences Panel>Displays>Color then click on the calibrate button.
 
You'd be surprised how little a problem it is. Most the people here are just gonna complain, people don't post when they have a good one.

Its like the iphone 4 antennagate, that was a big issue so it got publicised largely.

It's a LITTLE problem.

It's like antennagate, that was a BIG issue.

:confused::confused::confused::confused:

Thanks for the help Bloke!

Hey, if you have a lax schedule then it's no big deal to unpack it, test it, blog it, call Apple, beg for a return label, pack it back up, wait in line at UPS, ship it to Apple, wait again...

But if time is valuable to you, get a computer from a company that still cares. Sadly, that used to be Apple.:apple:

I don't doubt you truly believe you have this issue with your screens so I'm not calling you a liar.....I just think you have lost the plot a little. I'm sure that Apple isn't completely sad to lose you as a customer because you will never be satisfied.

Enjoy your HP or Dell or whatever you think is better than the Apple displays.

:rolleyes:





Hey mac, even the best can screw up.

Yeah I did calibrate it but it's still a problem. I have a gradient of White to yellow going from top left to bottom right.

Ouch, at least I can clearly see it, and I'm not the kind of guy that returns screens for some single dead pixel in a corner. :(

Hey genius, anyone with a basic grasp on statistics would know the issue is bigger than you think as people are returning 2,3 and 4 machines...

and the reason its not on lots of news sites is that Apple sell (in relation to the market) very few computers.

13-14 mill total out of a worldwide market of 300 mill annually.

of those 13-14 mill c. 70% are laptops.

how many iMacs do Apple sell per year? 3 million absolute max (worldwide)

not worth bothering with really....
 
Yeah I did calibrate it but it's still a problem. I have a gradient of White to yellow going from top left to bottom right.

My advice is not even bother to explain. McFans have no idea what calibration, or statistics is, and only that Apple cares and can do no wrong...

Really? I thought McFans are the ones who complain alot?

I was liking this post until it took a weird turn with people complaining about their yellow screens - but I guess such is the nature of this thread.

I was wondering would it be redundant to put up a new thread for people who have perfect screens? Because that is the question I can't get answered from reading these yellow screen threads.
