27", 21.5" iMac Owners, test your screen for yellow tint issue here

[boombashi]

ok so new week 53 iMac 27"

the yellowing looks to be gone but thats this light on a black screen?

also one dead pixel in my isight

Wow, and I thought I had bad back light bleeding. It looks like they are getting worse. No, this is not normal...I've seen displays in the Apple Store that have zero back light bleeding.

You don't see the yellow? It's pretty strong in that first picture.

People, you gotta get a refund for these things. These are VERY poorly produced machines. I got two crappy ones, then got a refund. I'll tell you, the 2 grand feels a lot better than a shiny, yellow machine.

I just returned my 21.5 3.33ghz, ATI for a replacement due to the Yellow tinge issue. Also, I ask them to send the replacement with i7 model instead and I will pay for the extra charge.

I have been using my new iMac 21.5 equipped with the topmost model available and I still feel I need more powerful one for my software jobs.

It's worth upgrading sicne I only paid another $500 and get more 5.5 inc screen, better CPU (C2D 3.33--> Quad i7) , and better GPU (ATI 4670-->4850)

Anyone think the same? Do you think how long or how many year this model can serve me or can handle the future technology in term of its performance (not the hardware issue)?
Could it be at least 4 years?

Now, the only problem to be worried is all current issues of 27 inch iMac with i7. I asked the Apple advisor about those problem like yellow tinge, dead pixel or flickering screen and he said "We have been focusing on QCing the newest or just-built system (espeacially the custom oreder)to assure that there is no any issue before shipping"

Yeah right!!

I see the yellowing in that photo clearly as well. It's quite pronounced.

You don't? I see it right away in your screenshot.

Surface blur + Saturation boost:

Original colors (no saturation boost):
31 by 31 pixel average in top left of the white area: #d0d2d6
31 by 31 pixel average in btm right of the white area: #c7c5c1

Of course the closer the circle is to the bottom of those color graphs, the less it matters where the circle is from left to right, but you can clearly see the tendency toward BLUE for the top left, and YELLOW for the bottom right.

Just feel lucky yours is so desaturated. I believe mine is about the same as yours, and my gradient is in the same orientation. You only have a max of 6 difference between R and B (C7 vs C1 and D0 vs D6), so it could be much worse.

I am sticking with mine as well. Have been doing some work on it and it really hasn't affected my ability to tell that something is grey. I have software that tells me that. As for colors I'm aware the color temperature must affect them some, but I feel it's hardly noticeable to the eye. And I can always move a color swatch around the screen to see. It's just the greys and whites that are problematic for me... Notice it a bit too often in those situations.

Dear Jonwd7,
Thanks for analyzing my screen shoot. I now see it after increasing the saturation in photoshop. I would guess that a lot of people reporting no problem in fact have a yellow tinge problem that they do not see without enhancement .
RATS!!!

Before you get worked up about it, make sure your photo is taken dead on. It looks like the left side of the screen is closer to the camera in the photo. This will cause some natural gradient issues.

As I type this, I am sitting on my couch working on a 40" Samsung monitor. I am sitting towards the right side and can notice a slight change in shade when comparing the right side, which is dead on centered with me, to the far left side. Your screen looks slightly yellow, but it doesn't look terrible. I've seen far worse. What it means to you, is entirely up to you though. If it were me, I'd return it.

 

[ttopp]

so i'm taking the 1st replacement to a reseller to get the bleed fixed

hope it can be done quick.

 

[ordiple]

Wondering how many of you would just live with this yellow tinge problem?

Applying for a exchange is extremely bothering in my country...

 

[tomkruk]

Week 53. Still there

I just got a new iMac 27". Week 53 still there.

 

[rigid]

Just got my week 53. The bars on the bottom of the screen look slightly darker than at the top of my screen but I don't see any yellow.

I would probably have just lived with it if my new $4000 machine wasn't also flickering...

Ocd

Well, I am not sure why I am so obsessed with this thread. I cannot see the yellow on my i7 screen. But my camera can. I decided to do a little experiment.
The first attachment below (left set) is my i7 with a neutral gray screen on the left and the same photo on the right with the saturation cranked up by 50% in Photoshop.
The second attachment (right set) is my 2008 17" MBP with the same parameters.
BTW, even the photos on the left of both sets show an intensity variation from left to right in the photo that I do not see sitting in front of the monitors.
Yes the i7 is worse, but since my 58 year old eyes can't see it, I am keeping the machine.
Please note, that I do not intent to diminish the people that truly have a yellow streak problem. Previously posted photos show it to be quite obvious to even me. I think Apple is timid about officially confirming the problem because of the flood of returns it will cause.

Your screen looks good to me. If mine looked like that I would be happy.

 

[lexvo]

It looks like the yellow tinge comes in different gradations. Mine is also not as pronounced as some other photo's I saw, but it is worse than BobK's.

I had a Week 50 21.5'' that had bad yellowing in the bottom right corner. I bought from Amazon (little cheaper, no sales tax, free shipping) and took it back to the Apple Store today rather than trying to return it.

Apple store took about 5 minutes, agreed that the screen was yellowish, and got me a replacement out of the back and did a direct exchange.

I've yet to boot up the new one yet. I'll do so soon. But good experience at the Genius Bar, even with an Amazon purchased machine.

 

[Kirill Sharapov]

Greetings from Russia. I bought an iMac 27 and its screen also has a distinctly yellow tinge at the bottom. Week 43. I'm waiting for an official response from Apple.

Another week 50, good screen though. I guess I'm one of the lucky ones.

I have seen the yellow tinge problem so I don't deny its presence on some screens.
But there is not one photo in this entire thread that is an even remotely accurate representation of the yellow tinge problem. Yet some pontificate about one screen being better than another based on this non-evidence.
Even the photos shown in the initial posting of this thread, purporting to be evidence, are useless. They claim they show the top and bottom gray bars looking different and this is supposed to be indicative of something. Yet even a cursory glance at ANY of the light gray horizontal bars shown in any of these "evidence" photos shows a similar disparity in tone even within and across that particular bar! Look at ANY of the light gray bars and their left extremity is a completely different tone to the right extremity of that same bar. In most photos, the difference in tone within any one bar from left to right is actually more than the difference between the vertical comparisons.
If ten people take a picture of the same clear blue sky with ten different cameras, they will all be able to argue that their sky is either different or worse or more/less accurate than the others. However, the results will prove NOTHING about the exact color or gradation of the sky at the time and will say more about their cameras and lenses than anything else.
No-one here has shown a single photo where the gray tones used for testing show a consistent tone from left to right.
It's as useful and accurate as measuring a distance with a ruler that isn't flat.

Inclined to agree, the whole taking a photo of your screen is not really that useful or accurate a methodology for gauging any yellow tone yet people are treating these photos as if they are forensic evidence. By the way, I do acknowledge that there are some yellow hue issues - I'm not a yellow hue denier.

 

[MattiasN]

A little suggestion to you people that mention that you have bought/received iMacs without the yellow tint. Could you please also mention if you have owned or looked at an iMac that has the yellow screen issue. It's reasonable to believe that not everyone is able to see the yellow tint at all, so it gets a little bit more interesting to know if you have seen it and know how it looks like.

Sir Cecil and spcdust: I agree that photos are not evidence of the issue, but they gives a slight idea of the differences in shade. And personally I think it's more "reliable" to look at a photo than to read a post of someone saying that they have a screen with yellow tint. I have tried to take some photos of my yellow tint screen and as you suggest it's very hard to re-create in the photo what I see on the screen. However, I managed to take a few pictures that was acceptable, I will post them later on.

 

[Kasperl]

@Sir Cecil: 100% ACK, Thank you

 

[slicecom]

No-one here has shown a single photo where the gray tones used for testing show a consistent tone from left to right.

Agreed, but the point is to show DIFFERENCE, and the DIFFERENCE between the top and bottom bars is significantly more than the difference in the gray tones side to side.

Scientific accuracy and measurements are unnecessary when the problem is clearly visible with the naked eye.

People are taking pictures and posting them up here, who cares if they want to compare their yellow tinted displays to other peoples yellow tinted displays? Bottom line is they have yellow tints, and its unacceptable.

 

[ttopp]

I think the pics are just to show what the screen looks like. and as a gauge for feed back from others. I have people saying my last pic had yellowing, it is noticeable (slightly) in the pic but was different in reality.

Also the black screen the pic shows it different but that b how light and cameras react. again it wasn't so bright but is a really noticeable difference in the bottom corners when I was watching starwars. space went from black to gray lol

anyway I am taking it into a shop to get it looked at tomo. I hope they fix it.

iMac 27" the bottom bar looks more yellow

 

[kfscoll]

The simple fact is that some posters on this thread are Apple apologists who will deny the existence of the "yellow tinge" issue until the bitter end...despite significant evidence to the contrary. Apparently the mentality goes a little something like, "My computer doesn't have the yellow tinge, therefore the rest of you are making all of this up. After all, Apple can do no wrong!"

Now, I love my Apple products, and, in fact, I have a 27" i7 with the yellow tinge. Rather than playing the exchange and refund game, though, I've decided to hang onto my i7 until Apple gets their arms around the issue. My tinge is minor enough that I could live with it if need be. I have faith that Apple will eventually solve this problem, but I'm not so naive as to think that Apple can do no wrong.
