Ok, genius. You forget that the Mac Mini also sells for a premium price.
The current iMacs are more competetively priced than ever, but are still expensive, hardware wise.
And the entry model with 9400m graphics is laughable.
When done with their upselling, you're paying much more.

Good looking though.

Yes, that's what I mean. Your only choice is to switch from Mac to something else or buy an pricey Mac Mini (I don't need it that small) or a hefty MacPro (besides it's a monster machine for those that need it, it's way over spec for me and consumes too much energy for my private uses).

Part of their pricing already covers for our exchange escapades. Maybe "they will notice" because we do so. What would change if we all were quiet and kept our machines? Apple is the same company that ships replacement iPod headphones by Express (which is approx. 30Euros to Germany) - for a part worth only a couple of bucks. So, they seem to have plenty or repair budget.
Besides, I also paid a hefty price for AppleCare to bolster the measily 1 year warranty of Apple.

Hi, guys sorry for my previous post where I sent the printscreens and not the real photos of my display.
I think it's yellow in the first 1/3 (from the lower) of the screen, maybe it's the "natural" gradient of the LCD or it's faulty.
Just have a look at the photos (hope they're good enough!) taken few minutes ago.
Thanks.
regards

Actually, it looks acceptable to me. If I ever had a screen on mine like this (or like the impression I get from your pics), I would have kept it.
 
I received my 21.5" from the refurb store last week. According to the serial number, it was a week 7 (which I thought was strange for a refurb to be so recent).

The yellow issue was present but only noticeable in Safari or iTunes (essentially where white was present), so I decided I would live with it and decide later, but within my warranty period, to get it worked on. Unfortunately, it had a more serious issue of frequent kernel panics when plugging-in headphones or speakers. The logic board is currently being replaced.
 
First screen replacement was done in 24 hours. Second screen replacement seems to be taking much longer and no-one will return my calls to let me know what's going on. Brilliant.
 
yellow ?

Hi everyone,
I got my iMac 21.5" yesterday. What do you think of my display ?


day2/ brightness 100%

Agreed, that one is absolutely perfect and any variation is perfectly within acceptable allowance. THIS is what the iMacs should be looking like!

They pictures look OK to me. If the real screen is like that, that's absolutely acceptable. Never seen such a screen personally, at least not in an iMac ;-P

@all: For judging the pics: Make sure you do not look at them on your own, possibly yellow iMac!

Mine is exactly like yours. Week 7 i7. A bit yellow on the bottom, but not enough to ask for a replacement.
But it is there.. And sometimes it annoys me knowing that it is there.

Let me as you guys something:

I think I will not ask for a replacement. But do you think I should call AppleCare informing them of the situation? I am asking this because I will definitely consider a repair when new panels won't have the yellowing. Imagine that 2 month from now the displays will not have the yellowing. Will I be able to arrange a repair freely? (I have AppleCare)
Do you think a repair is risky? I've heard situations of iMacs coming worse..

Since you have Apple Care, you have 3 years to start making it "official".
My experience is that the exchange panels are not better:

My machine is in the second time at an authorized apple service - they started swapping the panel the 3rd time now. We agreed for 5 tries - but until now, they only became worse (the one I got after the first repair beginning of February was yellow, but still the best so far). If it does not come out at least "OK" on the last try (which then would be the 6th panel built into this machine), e.g. like the ones on the pics right above this posting, I will re-register my complaint with Apple Care and consider a refund, if they can offer it to me. If they can't (didn't buy at Apple directly) I will wait at least 1/2 year and try again.

I don't ask for a perfect screen, but a color anormality of this degree is not state of the art. Also, Pixel-defects are not state of the art anymore. I could rather accept a slight uneven backlight distribution than an error with the color. Maybe I'm picky, but I'm writing this message from my 4year-old's Ubuntu machine with an ancient Samsung 701T which still has a better picture (except for viewing angle, of course).
 
Problem persists

Today I took my 27" i7 to the "Geniuses" at Apple for a replacement display. I was informed that the display was one of the "new ones" with a new part number. The folks at the Apple Store claimed to have put the machine through rigorous testing before replacing the display and found nothing wrong. That tells me they are totally clueless since the only test needed is a pair of eyes and the grey bars or a colorimeter, not some software diagnostic! After pushing them to replace the display as was the plan based on my discussion with AppleCare customer relations, they went ahead and did so. I was shown the display in a brightly lit Apple Store so it was quite difficult to tell if the issue was resolved.

I took my iMac home and allowed it to warm up for an hour before doing my own tests. I used a Datacolor Spyder3 Elite colorimeter to test the color temperature uniformity of the new display. A test area of a light neutral grey was used (almost white). I measured the color temperature of this test area in 4 quadrants: left upper, left lower, right upper, and right lower.
The results are as follows: left upper=6708K, left lower=6555K, right upper=6331K, right lower=6134K

The difference between the left upper and the right lower is 8.5%. That amount of variation doesn't seem right to me. What do the rest of you think? At this point I am fed up and will probably ask for my money back and wait until the next generation of "ultimate displays" to see if they are able to truly re-engineer them. I am sick of the lies I've been hearing from Apple about how they have resolved the issue.
 
Hi, Here find two pictures of my Imac screens, The first one as changed Big yellow on right part of the screen only ok on the little part on the left of the screen.
The second one (Ok for Apple) is yellow on the bottom of the screen.

Again sorry for my poor english.

It's an Imac 03 week. The screen has changed on week 06.

Thanks for the pics. Could you put a date on these images. If these iMacs were made within the last week, then it seems that Apple lied to gizmodo about the issue being resolved!

Can you also pictures with no saturation applied? Then they are easier to compare with the other pictures posted here.
 
Hi. Here is a picture of my 27 iMac production week 06/2010. The screen is slightly yellow on the bottom and the right side. The two rectangles in the middle are one from the upper right and one from the lower right. What would you do with this? Keep it or bring it back to the store and ask for exchange or refund.

 
I know this isn't strictly the correct thread. But has anyone given up on Apple with this screen issue and opted for a custom PC? I've been looking at some sites and found one (UK based) that offers x4 3.2Ghz qaud core intel processors, better graphics card, Liquid cooled, more firewire and USB ports, and SSD for under £1600.

Installing Snow Leopard is easily possible and at the end of the day Apple use the same core components.

What does everyone think?

I, as well as many on here I'm sure, used to build PC's, so I'm aware of what is available on the hardware side, which really isn't the issue. Although Windows 7 has come a long way, I still largely prefer Mac OSX. You can Hackintosh all you want, but its not a native configuration with the hardware, and will most likely be buggy and have issues, which is precisely why I spend more money on the Mac 'environment'.

In terms of hardware and footprint, the iMac is all that I need from a performance perspective, and should cover 95% of users out there and then some. I was never fond of having a box sitting on a desk or on the floor, and the size/footprint of the iMac is a HUGE strength for this system.

To each his/her own though. Hopefully, it looks as if the screen issue is a problem of the past, so you should be good to go!

Looks fine to me. Although I know that there were plenty of yellow screens out there, especially on this forum, I think that the topic has certainly 'created' the problem as well, when there is nothing to see to begin with. I'd say this is an example of that. Screen looks fine to me in terms of color uniformity. I'd sit back and enjoy.
