I'm amazed this thread is still around.

Why are people using iMacs, built for consumer applications like browsing the web, watching movies and playing games, for professional graphic work? That's what the Pros are for.

"But you don't need a Pro to do professional graphic work!"

Well, if you're noticing uneven LCD backlighting, obviously YOU DO. Most people don't notice it. I bought a new 24" a month ago and there very well can be uneven lighting -- I don't notice it. What I do notice is how nice videos look, how smooth Warcraft runs on it and how the computer itself is a decent-looking addition to my den.

If color and lighting is so important to your work, you need to buy the products THAT HELPS YOU COMPLETE YOUR JOB -- not skimp out and buy a consumer computer. No one gets a free phone from their local cellphone company then wonders why it doesn't email as well as a Blackberry. No one buys a Prius and expects the performance of a Ferrari. Why buy a consumer computer when your needs are obviously going to be met much better by a Pro?

"I can't afford one..."

Well, that's another matter entirely. Until you can, you'll have to accept the fact that cheaper computers and screens may not give you the results you're looking for.

i'm sorry, did someone say something? i could have sworn... it... it sounded like someone vomiting... humm.

Either Apple are becoming terrible with quality control, or this thread has attracted the eternally nitpicking members of society. I tend to lean towards the latter.

Copy & Paste is a wonderful thing, as is the internet a wonderful FUD amplifier. You guys should get out more, SAD.

there it was again! sounds like a bloated bowel releasing toxic gas... i must be hearing things...

"Clearly" ;) seeing as you are the authority on all Macs sold, and to whom! ;) got to laugh at you really for that stupid comment, but hey - thanks for making me laugh - made my day.

Anyhow kids, I'll leave you to your inane whining. Hope you resolve these 'issues'. Take a hammer to the retailer and sort it out with threats :p

sorry to interject here, um *looks at name-tag*, newbie. it's nice to see such blatant fanboyism from new "switchers" like yourself, but it's perhaps best that you let us grow-ups here have our discussion on issues that you're clearly incapable of understanding.
 
This thread and other like it, are obviously going to be a magnet for those people *WITH* this 'fault'. There are probably many millions of 24" iMacs out there that DON'T have this 'fault' at all.

Hence, you are only going to hear about the bad ones, on a thread DEDICATED to complaining about them. Logic really. If it were THAT bad, then they'd all be returned to store, or recalled.

Madness as ever, propogated and fuelled by the phenomenon that is forums.


Darkroom... calm down dear, it's not the end of the world, it's JUST a computer.
 
I guess I'll join the chatter...

I just picked up one Sunday. I personally think it's fine. In fact, the last couple of screen shots, where others said they noticed it, looked perfectly fine to me.

I really believe it's just in the eyes of the beholder. Every single imac i've seen IN PERSON was slightly lighter on the left side. Still the screen is far better than any LCD I've looked at. There is very minimal backlight bleed (a soft glow on the bottom, but better than my old one).

BTW, here is mine: http://public.ryanpetersonline.com/new_screen.jpg

Thoughts?
 
This is very troubling. I would be very appreciative if anyone ordering a 2008 iMac could post their experiences here. It seems from the above poster that the problems may not be resolved after all post week 20.

I'm looking forward to purchasing a 3.06 iMac next monday (barring the release of an xMac, lol!). Every aluminum iMac I've seen suffers from these problems, to varying degrees.

I can tolerate moderate backlight bleeding...but the gradient and color cast are intolerable!

I'm surprised that this problem isn't receiving more media attention.

Of course it's not receiving media attention...because it SHOULDN'T.

The majority of happy Mac users is not on these forums...they count thousands or perhaps millions, and are out there enjoying their fantastic machines, which can be easily considered the best desktops on Earth. Nothing else comes close.

I haven't had issues with my new iMac (unless I really wanna find them with a colorimeter/spectrometer/whatever), and I would advise any prospective users to take these forum "advices" with a grain of salt. Some people may have problems, but MOST DO NOT, and are absolutely happy with their aluminum Macs. Even those owning 20" models are fully satisfied in their majority, and couldn't care less about narrower viewing angles or anecdotal evidence that the screens are "bad".

Again, read these forums and use your rights; but don't reach the conclusion that bad iMacs are the rule.
 
That looks just like mine (see picture earlier in this thread), with just a minimal tint. Now all we need is a photo from one of the "perfect" screens (for example the starter of this thread?), so we can compare this perfection with ours ;)

I really believe they're all like this. I have honestly compared at least a dozen of these machines and all are the same way. Granted, I can notice it if I stare, but on the other hand, I have YET to see a perfect LCD from ANY manufacturer.

My other 19" screen I have has horrible "halo" bleed on the edges and blotchy blacks. My macbook screen has two lighter patches near the bottom and obvious gradient top to bottom.

In the end, this imac screen just pops!

I agree, but most people who buy these machines are still your average consumer and will not even begin to know if their machines have the issue or not, or even nit-pick it like we do. They are not enthusiasts like us who share their experiences on forums. Given that, we cannot guarantee that those who have not reported it have perfect screens. Not saying that's bad, but it really is a consumer machine and normal users will not notice.

I'm really anal too, but given how many I've seen have this issue (again, at least a dozen in person), there's no point in trying to get an exchange that can A) be worse backlight bleed, B) have worse gradient, C) have a dead pixel, or D) have any other possible issue that can warrant an exchange... then the process starts all over.
 
Here is an example I came across recently:

https://forums.macrumors.com/posts/4425816/

In that thread, a poster said his screen was perfect, as did a handful of people who followed up on the post. However, in these pictures, it clearly is not. It really boils down to the tolerances of everyone's eyes.

In the end, this screen has been called perfect by a good amount of posters in the thread, yet it suffers from the "problem" (I feel this is inherent in all LCD's). Take it for what it's worth, but that's just my observations.
 
Again, read these forums and use your rights; but don't reach the conclusion that bad iMacs are the rule.

No one tried to say that "bad iMacs" are the rule. The other extreme is just as bad, the fanboys who proclaim everything Apple makes to be pure perfection.

There are gradient issues in the 24" iMac line. No, not all iMac screens are affected. I went through two before I got a good one.

Can you show us a photo of your screen, please? Even though a photo is a poor representation I think it will give us a general idea of what you consider a "good one". :)

It's simple really; some people will NEVER be happy, and are always LOOKING for flaws to moan about, even if said flaw is barely perceptable at all. Point something out - no matter HOW small, and soon you'll all be noticing it more and more, and creating pointless rant posts in their thousands!.

Some people are never EVER happy - the rest of us get on with our lives. Keyword here: LIFE, as in get one.

Gotta say I was pretty sure I was going to get a good screen on my first try at a 24" iMac. I have been very lucky in my time buying LCD equipped devices to get a perfect one every time. I know there are bad ones out there, but figured the complaints here are a very small minority.

Some folks are pickier then others as far as screen quality goes. If you know what near perfect light distribution looks like on an LCD, then you will be quicker to notice something less then perfect. Most of us don't know what it looks like because we have never seen it nor have the tools to measure it. Others look at it as good enough and never give it a thought.

I know one thing for sure. This thread and others like it are educating folks to look for backlighting and pixel defects. At some point each buyer looks at their screen and can either see it or not. If they see it they make a choice to live with it, seek help or return it. What is the ratio for acceptable vs unacceptable? We will never know and it does not really matter. Those that get returned will either be in sufficient quality that the market will take care of the problem by forcing the manufacturer to fix it or they will continue to pump out the product as is because they are making a profit.

My opinion on some of the complaints is that you have semi-pro's or professionals trying to make due with a consumer product that has relatively poor quality control during the manufacturing process. The QC is kept to a minimum to keep costs down and profits up. A certain level of returns are accepted as part of the business. They also turn around the returns, sell them as refurbs and still turn a profit. People buying refurbs are more likely to accept a less then perfect product to save some money. My experience with Apple refurbs has been that they are a great deal. Quality may vary, but hey you can save a lot of money if you are willing to settle for something that was returned. Add to this that many don't know a backlight from a porch light in the consumer market. As long as the case looks good and it works, they are happy.

Oh ya, I got my 24" iMac. Beautiful display. Bright color. Little brighter on the left side then the right. One dead pixel in the upper right area of the screen and something over a HUNDRED stuck pixels all over the screen.

Had it not been for these complaint threads I probably would not have noticed until I put up a solid black background. How long would that have taken? Sure was cool the way solid black on that Mac changed a dark night into a starry night in a hurry. Could not see them with any color screen except black. How many people never check or use a solid black background? Dunno, but I did check. Anyway I sent Starry Night packing and got a replacement within 8 days. Its perfect as far as I am concerned. No dead or stuck pixels and the backlight looks good to me.

Thanks DarkRoom, D4F & SaSaSushi, Dantay and all the others for keeping the rest of us on our toes.

D4F and SaSaSushi, I listed you together since I rarely see posts from one without posts from the other. I listed you guys in alphabetical order so as to show no favoritism:)
 
For the record, here's some quick shots of my screen. You can clearly see the backlight in the four corners (because, surprise surprise, that's where they are on an iMac). Am I upset? No. Why?

*Because I have a Mac Pro and a fully-calibrated LCD for photo editing at the office.* The iMac is for watching movies and playing games with the kids.

We actually have a saying at work: "The secretaries get the iMacs. The creatives doing real work get Mac Pros."

I don't understand why many users suggest that this issue doesn't merit attention. Nobody in this thread has suggested that they don't like their iMac, nor that they don't love their iMac, nor that they wouldn't recommend one to a friend. But they do so despite the screen problems.

I recommend the iMac to friends and family all the time. I just purchased and installed a 20" for my mother's office, and encouraged the purchase and set up a 24" for my father's business. Nobody is suggesting that they are bad...or even that they aren't one the best desktop computers money can buy (I believe they are!).

However, I do understand why many users feel that the problems with the iMac screens aren't a big deal. Most people have never owned or used a S-IPS or H-IPS display before. 90% of the monitors sold at your local electronics store are TN displays. Poor viewing angle and color shifting at angles are the norm. It makes sense that a switcher, or someone coming from a TN display wouldn't think the color cast or gradient are an issue, and wouldn't understand what the fuss is all about. Most if not all of the iMac displays DO have problems in my experience (to varying degrees), but most users won't care. Coming from a TN panel, the 24" iMac, gradient and all, is still a huge upgrade.

Let me tell you my story. 2 years ago, I could have purchased an iMac with today's iMac's screen, and I, like you, probably would have told people to stop complaining.

But I purchased a top of the line white 24" iMac. For as long as I owned that computer, I never thought about the "quality" of the display. I did however, log a few thousand hours using the screen. I gamed, browsed, but particularly, I watched a ton of video content, from across the room, using front row and an apple remote.

In April 2008, after owning the machine for 19 months, I decided to sell it...anticipating an update to the product line.

For the last 6 weeks, I've been using a borrowed macbook connected to my 22" Acer P ("Professional") series LCD. Don't get me wrong, it's a phenomenal display for a TN (dead even backlight, very minimal backlight bleed, no colour cast), but it's night and day compared to the S-IPS in my old iMac.

The first night using this set up, I invoked front row, and threw on an episode of a favorite tv show. Something was wrong. Blacks were inverted on the top half of the screen. Hmm. I was lying on the couch about 8 feet away from the screen, two feet below it. The vertical viewing angle of the TN display wasn't sufficient to watch a tv show in this orientation (the image looked great if I sat up though!).

A few days later, I went into my mother's office to set up a new 20" Aluminum iMac. While setting it up, I copied several network and printer settings from a nearby white 20" iMac. I was floored by the difference in the quality of the displays. The color and "depth" of the image on the white iMac were incredible...I saw no color or brightness changes looking at the screen from 180 degrees. The Aluminum 20" was a whole other story...massive color shifts (inversion if the angle is too steep).

A week later, a refurb Aluminum 24" iMac was purchased for the house. At first the screen looked fine...but after opening a few fullscreen safari windows, the flaw was evident. The centre of the screen was muddy (warm) in color, whereas the left was fairly cool, and brighter than the right. The computer also has moderate backlight bleed in the corners.

Since then I've checked 3 or 4 more units belonging to friends, my father's office, and a local electronics store. All of them had most of the issues, to varying degrees of severity.

By comparison, my sold white 24" iMac had no gradient, no visible bleed, and dead even color.

some people will NEVER be happy
Previous (white generation) iMac owners probably won't be, until new screens are made available in the iMac. The 20" white iMac shared its panel with the 20" ACD, and the 24" was even better. Critics praised the white 24" iMac for bridging the consumer/pro gap (first consumer mac w/ firewire 800), and it was a viable professional work station.

S.J. told us in August 2007 that the displays in the Aluminum iMac are better, more professional, etc. While that statement is not true at all for the 20" iMac, it's true on paper with regards to the 24".

The 24" Aluminum iMacs have H-IPS displays in them, the best displays commonly available on the market. All the "consumers" in this thread are looking for, is for the display to work the way it should.

I read online today that threads on the Apple support forums with regards to screen gradients in the iMacs are being closed or censored (link:http://www.tomshardware.com/reviews/apple-display-update,1747.html).

However, barring an update to any of the computers in the Mac lineup, or the introduction of a new computer, I'm going to buy a 3.06 unit after the keynote on June 9, and hope for the best.
 
This is no longer especially relevant since the thread degenerated but

I received my iMac 24" yesterday (built week 21) and it has no stuck pixels, no screen bleed and no gradient. At least as far as I can discern it just works.

is yours from china (W8) or czech republic (VM) or some other place? as far as i can assume from reading these threads, both week 20 and 21 from czech republic were produced with good screens, but week 22 screens from czech republic were bad.
 
We actually have a saying at work: "The secretaries get the iMacs. The creatives doing real work get Mac Pros."

Sounds like you work with a bunch of severely stuck up individuals that ought to get out of the office more.

How is creative work more real than what the secretaries do anyway? What a pompous attitude. I'm very glad I don't work there.
 
Dodgy statistical sample?

Mine is a VM code. I think you're reading too much into a very dodgy statistical sample. I suspect that many existing mac owners who upgraded have not bothered to post that they are satisfied with their new macs because they *expected* to be satisfied so they don't read anything in particular into the outcome. I'm sure a huge majority have got good screens from any week - they just didn't read that there was a problem so they don't fell compelled to come on here and talk about their macs.

Of course, having a nice machine, I would say that ...
 
I take it we´re not going to see any photos of a perfect screen then :p

I don´t care anyway, I´m happy as a puppy with my 24" iMac. I have no backlight bleed, only one stuck pixel, a few fingerprint smudges on the inside of the glass, and just a minimal tint on the right side. Turning up the contrast actually helps minimizing the tint. In fact I´ve never owned a mac with a perfect display of white, my eyes always seemed to pick up some kind of discoloration tint (this is on MBP and MBA).

By the way, I tried the "repair stuck pixel fix" program while sligthly tapping the screen with a cloth directly on the pixel in question, and it appears to have been fixed. I say appear to be fixed, because the bad pixel was very hard to spot in the first place. It could only be viewed from a certain angle, and now I can´t find it. ;)

I wasn't ignoring your request I just don't think I'm up to the hassle of doing pictures right now. I did some of my first panel back in August last year. They should be done only in a completely dark room at low speed with a dark blue and/or dark grey background and using a tripod.

If I work up the energy to do so I shall. In the meantime I hope you'll take my word for it. Is this panel 100% perfect? No, but what panel is? If it's got a gradient it might take a luminance meter (or a digital camera functioning as one) to detect it.
