I used a Nikon D3 with an f2.8 80-200mm Nikkor lens set at 200 mm. I first selected a neutral gray screen color that was as close as possible to an 18% gray card. So the aperture priority and spot metering of the camera was very close. It does not matter if your whole screen shows slightly light or dark. You are just looking for a consistent tint (or tinge) across the screen. If it is consistent you can calibrate it out using one of several screen calibration units on the market. I used a show shutter speed (1/15 of a second) on a tripod to eliminate any refresh rate problems. I used an Expo Disk to calibrate the color balance on the part of the screen that looked the most neutral to me. Further, because I was getting a moire effect in earlier posts, I used a polarizing filter to eliminate this problem. I have found that you get little edge fall off if you are a distance from the computer, which is why I was about 15 feet away with the 200mm lens and only filled the center 2/3 on the camera view with the computer screen. If you look back at my post you will see that my MBP had a more consistent screen than my i7. I do agree that unless you put all these iMacs in the same room with the same camera and settings that it is hard to compare one to the other, but that is not the intent. In the venue of this forum, with a little care, you can show a reasonable depiction of your screen. I am hoping that the sheer magnitude of this thread will get Apple's full attention and help those that have a real problem. Although my i7 has a slight tint (tinge) problem, I have decided that it is not enough to worry about based on my needs. That is my judgement.

Then I've underestimated your own particular efforts and capabilities.
Nevertheless, I don't see value in the end results.
 
it would be interesting to find this out. now, is samsung manufacturing panels for the imac 27"???
It's the same LG panel as the 27" imac I've read on different technical sites.

What I find striking is this

For the pros who make ends meet by editing photos or video, you'll probably enjoy knowing that this one boasts a 110 percent color gamut, factory-tuned Adobe RGB and sRGB modes (alongside a color calibration report), custom color adjustments and a smattering of mounting options.

Seems they went for RGB LEDS instead of the "cheaper" white LEDS.

I'm really torn because (in this country) this screen + a Quad Core i5 would probably be cheaper then going for a 27" i5 imac but with the big drawback that I can't run OSX.
 
iMac 27'' week 43

I go to tools centre. It is strange that apple corporation is silent till now about this problem.
 
I don't think your eye is that discriminating and the problem is very widespread

I have had 3 different Imacs and they all had the yellow screens.

I have also inspected the ones in stores and believe it or not, most of the in store demos are from that week 41 batch that did not exhibit this issue.

I am on my 4th and I'll bet my money that it will also have the issue.

If it does, i will tell Apple to make a note of it and hold on to that unit until they fix the issue.

At that point I will request a repair.
 
All things relative...

When it comes to photographing a screen, no matter the situation, there will be some flaws brought into the image from the camera. ...but the important thing about it is what we are seeing is the screen relative to itself - not to a different screen. NO camera is going to produce a yellow tinge in the middle of a display, unless it has SERIOUS defects itself. Consistent conditions are not required to take valuable images that show yellow tinged displays or reveal even ones.

Most camera flaws are fairly predictable - noise, moire, and darkness around the edges.
 
Hello everyone, Just got my 27" i7 week 50 delivered today, opened her up hesitantly but as of now I'm really having a hard time finding any yellow tinge in the display..

For the past half hour I've been staring at every centimeter & every corner with multiple solid grey & white backgrounds...as well as using the color bar test, dragging finder windows all over the place, I'm really actually getting a headache but I'm happy to say I haven't found a spot yet that seems at all a little off..
As an aspiring editor/visual fx artist I've been working on these machines for the past 5 years, not including my gaming days back in highschool :D Recently been learning/working with Color and as far as I'm concerned I couldn't be happier! It's only been a couple hours running so far, automatically updated a Display Firmware update after I booted up..
Anyways, I'll keep everyone posted if anything changes but as of now my week 50 IMac i7 is running great! Hope all this bs gets resolved soon, I'm really disappointed in Apple after hearing all about this but just needed the upgrade from my Powerbook G4 so I went for the gamble =D Cheers!
 
Dorsey - Sounds good. Trust me, if you had a yellow like mine I just boxed back up, you would see it instantly. 3/4 of the display was yellowed.

Treasure that i7! It sounds great.

I really hope my i7 replacement will be the same as yours :)
 
Called Apple today and set up the return/refund of the iMac... Very sad about this, but can't keep getting replacements with yellow screens, would rather get out of the cycle of replacements and hope for the next revision to be better built.

This was iMac #4, and all had yellow tinge with the exception of the first one (swapped due to noisy hard drive)... Well, the first one had very minor tinge on the bottom, but not like the last three where the yellow was very prominent on the screen...

At this point I plan to continue to use my old (but great) G4 Powerbook, watch the threads here carefully and determine when it is safe to jump back in the water.. Probably just be patient, wait for next revision and take advantage of the speed bumps (based on Macrumors iMac average for updates, looks like May timeframe possibly for next speedbump..)

Good luck everyone.. Sounds like some folks are getting great screens out there.. hope that gets more consistent!! Wish I would have been one of them..
 
Just received my week 52 yesterday way way way too late it's was ordered on Black friday 2009!

......And....it's got super noisy seagate HD and this infamous yellow peed face....oh my...what's worse the tint is all over the place except top corners, and the fan is even noisier than my 3 year old iMac.
And NO I am not gonna return it, cuz i've already waited too long, maybe i'm too lazy to swap it, i'll just rock with it until the HD or the display fail.

Wow. Sounds like the display is pretty bad as mine was. My HD was quiet though, so sorry to hear you have that issue too. Good luck. I wouldn't want to live with it like that, but I guess you have to do what is right for you.
 
Well,

You might remember my i7 came on Thursday with 3/4 of the screen BAD Yellow Tinge. It is on its way back to Apple for refund.

As it was in stock, I tried an i5 iMac from Amazon. It arrived Saturday.

The Yellow Tinge is *much* better. Your average 'ol joe or mum might not see the yellow tinge on the i5. However, at the bottom and in the middle, there is some yellow. With something like iTunes or a light web page, on the bottom right, it's not the very bottom either, it creeps up the screen some.

I don't know what to do at this point. The i5 is much better, almost usable, but it still seems wrong that portions of the screen turns light windows, yellow.

I'll probably send it back too. It's too bad a Mac Pro and 30 -inch ACD costs 2x as much as the iMac Quad as I'd go that route in a split second, but $4,000 would hurt too bad.

same thoughts as me with the macpro mate!

although id have the 24" acd
 
I brought mine (21.5") to be repaired today.
It was a different shop then where I bought it. All machines on display had perfect screens!

The shop technician was very willing to swap my iMac's panel, even without big testing around with any windows - just a light gray background was enough for him.
He never heard about the "Screen Noise", where the machines starts to whine when display is dimmed, but of course was willing to look for that. You could not hear it in the shop, although.
We also took a pic with fotobooth - and see: All "always on" pixels got magically repaired (maybe the 1 hr drive through the blizzard scared the iMac off ;-))!

Now let's hope I receive a good repair panel and that he can do something about the whistle.

Mine has the Seagate HD also, but I don't find it noisy! You CAN hear it it the head moves, but it's the most silent HD I had so far. I have a Seagate 320GB in my old PC the scrubs it's heads over the disks every 1-2 hrs for no reason - that's scaring!! But runs like this since 2 years.

Regards,
SuAlfons

My sister just got a 21.5" from Apple online (Australia). It is a week 50 and absolutely perfect. Both of us had returned one each previously. I'm over using my Macbook Pro 24/7 and I'm wondering if I should order also.....
 
Yep, That looks awesome to me :) what is their week of production? When did you get the no-problem one?

well its no got the yellowing but.. really bad backlight..

i was watching starwars and space was floodlight lol..

it was a week 53 ??

its in the shop, hope its getting a new screen thats perfect. 3rd time lucky :rolleyes:
 
my week 51 has a mild yellow tint cover the bottom quarter on the left side up to about half the screen on the right side, i think im just going to wait to call apple in a few weeks once they have their issues worked out as i dont want to exchange a machine with yellow tint for one with a flickering display or even worse yellow.

Apple should let me exchange it any time within warranty right?
 
Just got my 3rd 27" i7 and the yellowing is the worst of the 3. It is a week 53 :mad: It also has mild backlight bleed but a lot better than the previous 2.

Think I'll get a refund this time. Maybe buy one in a year's time if the issues are sorted. Sucks cos I like everything else about it.

no. they will try and fix the issue. after 3 attempts or 3 fails of the same issue you can ask for it to b escalated to a higher level they will let you know if a swap of the whole unit is available to you..
