Err, the LM270WF1 is 1920x1080, not 2560x1440. The iMac uses a LM270WQ1 panel.
My problem is I got a limited space in my room and I 'm a software engineer who needs a very powerful computer.
So, my computer has to be
1. All-in-one computer to save space
2. Very fast computer. I returned my 21.5 C2D 3.33ghz imac due to the yellow problem and not powerful enough for my jobs. I'm waiting for the 27inch i7 model for my updated replacement.
S0, Could you please find any All-in-one PC offering the same specs as iMac 27 inch core i7 ?
I went to Sony, Dell, HP, Lenovo, All of them offer their All-in-one Computers with lower specs than iMac 27. Surprisingly, Some of them even more expensive than the iMac. (like Sony)
If you need comparison chart, let me know, I had done it before ordering mine.
So your logic's are not right for me as well
It's things like this that floor me. Its easy to point to a 39 page internet forum and pass it off as a small percentage of users. But when people are getting 3 bad screens at the same time or 2nd, 3rd, and 4th replacements all with the same issue the idea that it is a small number of machines just does not hold water.
How can apple's representatives both on the phone with apple care and in the store have the nerve to suggest that this is not a common issue.
It's painfully obvious that it is a very common issue affecting *nearly all* imacs delivered recently.
Several rep's have told me that they "haven't heard of the issue" one told me "I've talked to lots of people who don't have the issue" which seems like particularly crafty wording. The in store guy gave me the same song and dance then i showed him two faulty machines (the only two that were free at the time) and he was still reluctant to admit it was a problem.
What is wrong with these people? I know the company still hasn't officially acknowledged the issue (wtf) and they have to toe the company line but it starts to get really insulting to our intelligence at a certain point and at other points amounts to nothing more than lies.
One rep told me that less than 1% of all imacs suffer from this problem. I have to call bs. Perhaps less than 1% of imac users are bothered by it, or notice it, or can be bothered to do the whole replacement game, or perhaps this percentage includes the number of people who haven't yet received their imacs (poor buggers) but that number just simply does not line up with the fact that I'm on my 2nd replacement and others are on their 3rd or 4th.
Anyway just fed up and needed to rant... Still deciding whether to play the replacement game or if i should give up completely, get a refund, and wait for them to start producing screens that work.
To add to this, an apple store official told me yesterday that they are receiving between 4 and 6 27inch returns per day per person..
That's a lot!
I'm now awaiting my 4th replacement...

Unbelievable.
You spent many thousands of dollars and get stuck with 3 bad machines.
This CLEARLY is a problem and it's amazing that Apple refuses to acknowledge it.
Good luck. you'll need it.
Either they are on backorder or as we are hoping Apple is taking the time to look into the yellow screen issue and is holding off shipping. However there is no delay for 21" iMacs. My concern is that the 27" is the "super star" and the 21" will be ignored.
Has any one received any new shipments lately?
What week is yours? And what does the screen look like?
Is it yellow also?

I really would not read too much into this apparent delay - every time the iMac delivery schedule creeps up people seem to think Apple is solving the "yellow tinge" issue......that's how rumours start😉😉😉
Which Apple Store? A physical store? With at least half-a-dozen "persons" receiving 6 per day, meaning a total of around 36 iMacs returned per day, per store? Ludicrous.
With over 200 Apple Stores, that adds up to over 7000 27" iMac returns a day!
Or do you mean the online store? How many persons in that department each day, actually processing iMac returns? Three? That would mean as few as 12 returns out of thousands sold each day.
Meaningless information, whichever way it is looked at. But some zealots will believe it is of consequence, no doubt.

Mark another yellow tinge!
My latest replacement from Amazon has Yellow Tinge. We're 3/3.
Unit 1 - i7 from Apple - Worst Yellow Tinge 3/4 screen
Unit 2 - i5 Amazon - Least Yellow Tinge, but not nice, confined to bottom
Unit 3 - i5 Amazon - 3/4 Screen Yellow, but not as deep yellow as unit 1
That is it for me.
I'm not trying one again until a next revision. There seems to be no hope.

No yellow at all it seems!
Lucky. They do seem to actually exist!
Thanks for posting your photo.

Apple is 0 for 3.
Machine 1 was a week 45. The yellow tinge was across the bottom 1/3 of the screen.
Machine 2 was a week 50. Exact same problem.
And my third machine is a week 53(?) with a big yellow spot on the center right half of the screen.
Frankly, I plan to keep returning them until Apple decides to get this right. I paid a hefty price for this machine that I rely on for color work, and Apple will get it right. I don't care how much it costs them in shipping. 😀

Just got my iMac 27" week 51 today from B&H...
I DO have the yellow tinge problem bottom right corner of screen.

Agree yours isn't all that bad at all. I'd probably live with that.
Here's an edit with the bottom and top directly on top of one another

I hesitate to say this, don't wanna ruin it for you, but I do see it clearly in the 2nd pic using the Tapplox screen test--and the bottom right corner of the 1st pic. But if you don't notice it, then pay no heed to me. Plus it is indeed a photo, so maybe in person it is perfect.
not likely.. you could try if in the UK for a refund and say your ok with a swap.. i think you should get a refund up to 28 days (statutory rights) for faulty goods, even though apple say 14 days our state laws stand over Apples.
my second i7 is in getting a new screen. they called to say the back light was goosed and they ordered the new screen 🙂 i asked for it to be tested b4 i get it back 🙂
returned 2nd iMac
Today I returned my 2nd 27" iMac i5 (that I mentioned yesterday).
I bought one yesterday (week 46) and returned it within a couple of hours because of the yellow. They gave me the 2nd one (week 49) and the yellow was across most of the screen. It was much worse than the week 46.
Today I returned the week 49 and they brought out a week 52 to test in the store. It wasn't as bad, but the yellow tinge was still there across the bottom. The Apple genius had a hard time seeing it, but the stores are lit very brightly which can make the yellow tough to see.
Anyways, I took the refund and I'll continue to watch how this issue progresses and hope for a solution. So it's back to my MBP for now.
BTW, I just wanted to say everyone at the Apple store was very nice and the genius that helped me both times was excellent. And he had never seen the yellowing before, but did comment that he saw some flickering machines.
That's my story. Will likely wait for Rev. B.

That's what I thought. It's a consumer monitor so I don't expect it to be perfectly uniform; LG cannot compare to a LaCie.
That's not to say I wouldn't return it if it were like some the others have shown. I just think there's a medium between perfect and terrible, determined by price.
I'll keep my eye on the invading yellow fog, since some mention the problem increases over time.
In person it does look better than in the photos; my cyber-shot and angles distort it somewhat.
I wouldn't worry about ruining it, that's what Applecare's for. I'm sure my eyes are far from the greatest.

That looks great! It's excellent to see one like this. Congrats!
I don't see the yellowing you're talking about. Toward the bottom it gets darker, but not yellower. It looks like it's due to the photo, though I can't tell that for sure.
In any case, if that's what I got, I'd take it with zero regret.
For what it's worth, this is what iMac #1 looked like (#2 is no its way). It's a little blotchy with the yellow and blue (didn't look as bad as this in real life), but the biggest problem is the horizontal shadow across the bottom of the display. Not sure what caused that -- maybe a portion of the backlight was not on?
