So i got my new imac 27 in and it's sick, I was enjoying it when i noticed a dead pixel, might be two next to each other not sure. It is also mounted to the wall in my kitchen with the versa mount so i am not excited about taking it back. Should i bring it back? Can i bring it back for only 1,2 dead pixels and can i bring it back to the local apple store even thought i bought it online?:mad:
 
I certainly would. Apple wants their "customers to be the most satisfied in the world." It doesn't sound like you are satisfied.
 
Yes you can, but you have to call to Apple so they'll pick it up because items bought online can't be brought to store.

If you only have one which ain't in center of the screen, live with it, that's what I did. I have 2 dead pixels but seriously, they only annoy you for few days then you forget them
 
Really depends on what the service manual says is the acceptable level of dead pixels. Apple calls this "Pixel Anomalies'.

The 13" MacBook Pro's replacement chart is:

Bright: 4 or more
Dark: 6 or more
Combination: 8 or more

The 17" MacBook Pro's replacement chart is:

Bright: 5 or more
Dark: 7 or more
Combination: 9 or more

So logic would say the larger the screen, the more pixel anomalies are allowed. Given that you only have 3, you don't even meet the minimum requirements for a 13" screen so I would guess they are going to tell you to live with it.

But of course it never hurts to ask!
 
I don't know where you live, but it's often the policy that you can always return online purchases within a week or maybe two for whatever reason. Since you weren't able to inspect your product as you could have done in a normal store, it's only logical that you're given the chance to inspect it first, and return it if it doesn't meet your expectations. Same as with fitting clothes you buy online.

So whether it's dead pixels, or you just don't like it, I'm pretty sure you can simple return it by making an appointment with Apple so someone can come pick it up. Maybe they can switch it for another one, or else you just ask for a full refund and order a new one. Or you tell them you'll do just that, so they might as well send you another one ;) .

Personally I wouldn't accept it unless it's perfect—especially for this kind of money. Good luck!
 
i would take it back and i wouldnt listen to any rubbish about acceptable dead pixels.. its brand new all should work..

i took a ds back cos o dead pixels and tried the ones in the shop b4 taking it away,, got a fully working one on the 5th attempt the manager kept saying it was ok, i told him i dont care its not ok with me change it or give me my money back..

to many people put up with this kind o crap thats y they try and muck everyone around..

no that apple is trying that i mean people like the shop manager i had to deal way.. apples always done everything ive expected o them :)
 
wall mount

Can you show us some pics of it on wall ??Was it easy to install the mount?? thanks alot
 
They will exchange it.

The guys in the Apple Store in Glasgow (Scotland) are always cool with doing exchanges due to dead pixels etc. They always remind me that I have a 14 day period.

Of course, you bought this online, so you have to send it back. That is why I avoid buying online - if there isn't something right, I can just walk into an Apple Store and politely ask for an exchange.
 
I have a small piece of dust trapped under my screen in the top left corner of my new 27" iMac. I can't decide if it is worthy of taking care of.

As mpuck972 correctly states, there is a criteria used to ascertain acceptable levels of dead pixels as LED screens can never be guaranteed to be completely flawless - the manufacturing technology doesn't allow for it. I think you'll find all flat screen manufacturers, such as Sony, Samsung, Panasonic, Sharp all have there own set out criteria to what constitutes unacceptable level of dead pixels. To put it into some context, I work in TV and we have industry HD "Grade 1" monitors that have no dead pixels - however we pay in the region of £12000-£16000 per monitor for this privilege.

Saying that, it would bug the hell out os me although Hellhammer is probably correct that after a few days you won't notice them as your awareness of them is probably heightened as it's your new "toy". If you really do have a few then return the iMac you could beef up your reasons for returning it by saying to Apple that your are a graphic designer and therefore these dead pixels really are an issue for you.;)

Remember though, you may get another screen with dead pixels in more prominent places and thus embark on a never ending quest of returning computers in search of a possibly unobtainable holy grail of a perfect screen.

Finally, if it's not a dead pixel and just a stuck pixel you could try running this over the area for a while (hell, you could try even if you think it's dead pixel)

I exchanged mine for three times and all of them had dead or stuck pixels. I decided to live with it.
 
I have an Acer x233h 1080p display ($170) with my Mac Mini, and not one dead or stuck pixel. All user comments at Amazon for this display indicate no pixel problems and high satisfaction.

I'm wondering why so many reports of pixel problems with these high-end iMacs? I would have thought the display quality with these all-in-ones to be problem free.

Like spcdust and mpuck972 said, it's basically impossible to create panels at this point that are 100% pixel perfect, so there will always be some panels with a few dead pixels. Thing is that you hear from a lot more people when there's something wrong with their stuff; if everything is working fine, they don't need to complain on forums. I'm sure that for every person that has a Mac with some dead pixels there are a whole lot of folks with perfect panels.

But even if they can't guarantee it, and even if you need to go back to the store 20 times, this is 1500-2000 bucks we're talking about! Let them deal with the broken ones and demand perfection!

Some pics for you. It's mounted in my Kitchen.

The bracket was not hard to put on screw the middle in first so the side holes will line up. Took me about 5 minutes

Consider that the display on the 27" iMac has 3.68 million pixels. Even if you are producing LCD panels with a defect rate of 1 in 10 million, that still means that one panel in 3 will have a defect in it. Go even further and consider each subpixel and you have a display with 10 million pixels, thus to get even a 1 in 10 throwaway rate for LCD panels you need to produce LCD panels with a defect rate of 1 in 100 million (that's 99.999999%). For each order of magnitude the defect rate goes down, the cost to produce probably rises by an order of magnitude as well.

Yes the process has improved with time and the manufacturing costs are decreasing thus you are able to have a higher tolerance, but even $1500 or $2000, is not enough to make a guaranteed zero pixel defect practical or profitable for a display this size. $2000 may seem like a lot of money for an average person, but the fact of the matter is that it is pocket change compared to the production tolerance required to guarantee a flawless display. Aircraft parts are typically required to have a defect rate of one in one billion flight hours which is why a bolt that goes on an airplane costs fifty dollars when the same bolt in the hardware store costs ten cents. Or why they use 286 processors in the flight computer and it costs hundreds of thousands of dollars to buy.

Hey thanks for the pics, looks like a great setup. Also I would return the iMac for the pixals.
 
Concerning dead pixels i would try to take it back, although those pixels are small if you know where they are you will see them. :(

But a little question about the wall mounting. Thanks for the pictures by the way. Did you have to take the iMac apart? I'm asking this because it looks like you have to remove the stand it comes with and that looks bolted inside the machine.

So confusing this when i look at my back of the iMac. :confused:

Very cool. where did you get the bracket/arm? Was there other parts you had to get from Apple? Thanks.
