Hardware :: 24 Inch LED Cinema Display - Are These Dead Pixels?
Jun 22, 2009
I'm on my third LED Cinema Display (for various issues) but I've noticed all of them have DOZENS of very tiny specs of color that are only apparent on a black screen. Furthermore, they seem smaller than an actual pixel (have to be up very close) and they are only apparent at certain angles (and even sometime change color) as opposed to dead/stuck pixels. These always pass my initial dead pixel check over a full black or white screen but I find them once I get in real close.

I just received a Mac Pro 2 x 2.8 Quad-Core Intel Xeon and 23-inch cinema display bought overseas through an Apple official house (though not an Apple Store due to low demand in my country) and I found out that the cinema display has one dead pixel.
Mi question is: should I try for a replacement (given that I should wait for it to be shipped from Apple) or is this among what is expected and reasonable?
I have heard that as the displays are larger, the amount of tolerable dead pixels increases, and for a 23-inch near 15 dead pixels are not a justified cause for a replacement. If this is the case, I should instead be grateful that I do not have 13 dead pixels.

I've got two iMacs in my posession currently from getting replacement machines. Both have screen issues as follows: iMac A - dead & stuck pixels, feint grey horizontal bar running along bottom portion of screen, bottom left corner has noticeable backlight bleed. iMac B - dead & stuck pixels, yellow tinge in bottom portion of screen. So here are my questions. Which iMac should I keep and submit for repair? (does it matter and why or why not?) How does the actual repair get done? For example, if I submit iMac B for repair, could I end up with a grey bar or backlight prob like in iMac A?
Are there multiple layers to the display when they fix specific issues? For example, let's say the dead pixels are on one layer while the yellow tinge is on a different layer, or are both issues on the same layer? I ask because if there are two or more separate layers, there is more of a chance to mess up so I may want to submit the iMac that has the least amount of issues.
Lastly and most importantly, has anyone submitted their iMac for screen repair for these issues and got it back 100% repaired? (no dead/stuck pixels, yellowing, grey bar, backlght bleed) These are #4 and #5 in terms of the number of replacements I've gotten now and I'm sick of it so I may opt to go for repair on either of these existing machines instead of going for replacement #6. But do you think a 6th replacement would be better than going for repair on either of these? Or not?

So after waiting 4 weeks my High-res Glossy MBP FINALLY arrived...I was so happy. Got home switched it on and WOW it really is a beautiful machine...After using it for about 30 mins however i noticed a small dot to the lower right half of the screen... I looked closer and realized it was either a dead or stuck pixel( I dont exactly know the difference). I did a few test on it, and its ONLY visible when a light color is on the screen (White, Gray etc) However when the screen is DARK blue, Dark green or black it cant be seen at all...
It kind of looks like a TINY speck of water or liquid the size of 1 pixel stuck under the glass... I noticed that it does get lighter and darker when i adjust the brightness of the screen. Can anybody give me some tips? Anything i can do to fix it? Is it in fact a dead or a stuck pixel? I tried the JSscreen fix which is basically a online tool that opens up a flashing screen...Ive had it on for about 30 mins...but no luck

I plan to buy a 27 inch Apple Cinema Display to connect my 13 inch Macbook White too. I also plan to wall mount it and use it to run my ps3 through. I've looked around on the apple store and found the Belkin AV360 to use. I was just wondering if there are any issues I should be worried about? PS3 on a apple display sounds sooo good Also I want to use wireless headphones for sound on the ps3.

Can someone with a 24" cinema display please provide me with the measurement from the desktop to the top of the display enclosure? I'm building a desk for my new iMac and might include a 24" display if all works out for me.

Apple on Thursday discontinued its legacy 20-inch Cinema Display, reducing its external display offerings to just two options: its new LED-lit 24-inch model for notebooks and its legacy 30-inch display for desktops.
"With immediate effect, the following products are 'End of Life' (EOL); Apple 20" Cinema Display," the Cupertino-based company wrote in a worldwide bulletin to its sales and service channels. "All backlog will be cancelled and there is no automatic order conversion."
Around the same time, the Mac maker also removed the offering from its various online stores. Inventory of the display is extremely tight, as production of the product is believed to have been halted late last year. One of the company's largest distributors, Ingram Micro UK, reflects absolutely no inventory (below).
Interestingly, the same distributor has also run dry of the current 30-inch HD Cinema Display with a delivery date on new orders well past due, suggesting it may soon follow the 20-inch model out the door. The 30-inch model is not listed as discontinued, however, as it remains the only Apple-branded display that can be paired with new Mac Pro and Mac mini purchases.
Apple discontinued its previous-generation 23-inch HD Cinema Display last fall while introducing its new LED-lit 24-inch Cinema Display (review), which was designed with the company's new family of notebooks in mind. It did away with a DVI connector in favor of a Mini DisplayPort connector, which Apple has said will become its new standard display interface, shipping on all future products.
While Apple is widely expected to introduce a second LED-lit display in the 30-inch range, it remains unclear whether a new 20-inch model remains in the cards. Any future display update would presumably coincide with long-awaited updates to the company's line of desktop systems.
The 30-inch Cinema Display is amongst Apple's eldest available product offerings, having been introduced back in June of 2004.[ View this article at AppleInsider.com ]

I just got the latest 13" Macbook Air and hooked it up to my Apple 24 inch LED Cinema Display. It works great but I've noticed that the resolution is not the same as when I had my 2008 Unibody Macbook attached to it. Everything is bigger (i.e. lower resolution) when the MBA is connected. I went into Display Preferences and changed it to the highest resolution but it didn't change. It's not that big a deal, but I thought I'd ask and see if anyone had any suggestions on how to get better resolution on the cinema display. Or is it not possible with the new MBA connected?

for the last week or so my MBA has been showing a ~3 inch bar running vertically along the middle-left of the display. Until today, the area looked just like blurry pixels (some things like graphics would still appear, so I don't believe the problem is with the pixels themselves). Now the area has become a gray bar of pixels.

When do dead pixels show themselves? If I have a new PowerBook and it has no dead pixels, is there a possibility it will in the future?

When I took my new Imac 24 out of the box last week, instantly i noticed about 3 or 4 dead pixels, they aren't too bad but it's only of those things you don't expect with a new computer and it can be quite distracting once you know they are there.... if i were to contact the place of purchase in regards to this do you feel i would be over-reacting to have it replaced or repaired or should i just suck it up?

Tomorrow morning the brand new MBP 13 2.53 goes back to Apple for yet another dead pixel issue! The Staff in my local store are so, so helpful and are always there to help, but this will be my 4th pixel related return. It's a mighty fine machine but I'm beginning to feel like "that guy" who always takes his macs back!

I recently noticed 4-5 dead pixels (gray, not fixable with software) on my 1.5 year old MBP (see sig below). Definitely a bummer as I had to go through 2 MBPs when buying this computer just to get one without any dead pixels. I don't know why or when these pixels died. I have AppleCare and I am wondering if Apple will do anything about this. Is there a threshold for repairs (e.g., only 10+ pixels is repairable)? Has anyone ever got a repair/replacement for dead pixels? Is there anything I can myself to fix this problem?

This is my first post on the site! Anyway, I have about 3 dead pixels on my 13" MacBook 2.16 GHz. My computer is still under Applecare, would Apple replace the display for free?

I took the plunge and bought a new 15" mbp. Came home and booted it up to find two maybe three dead pixels in the middle of the screen. One is red and two are gray. I tried using a site to get dead pixels out but didn't work. I scheduled an appointment with the genius tomorrow to see if he can help me out.

I read a few posts about dead pixels on the iSight, so I thought I'd post this picture to see what other people think. This is a screenshot straight from Photobooth, showing the image from my iSight when the black cleaning cloth is held up to it. No, those marks are not dirt (on the outside anyway). Other that this, my iMac is fine with the exception of a single dead pixel (I thought this was a thing of the past, but oh well) and I'm not 100% about whether or not I have the yellow screen issue, so I'll ignore it for now.

I don't have an iMac, but I do have a 24" ACD that I bought brand new a few months ago (not refurb). It has a single pixel that is constantly on and it's red. It drives me absolutely CRAZY...probably because I paid $900 for this display. I can't remember ever having a problem pixel on another display...all of them cheaper. So I'm curious about the iMac owners. Is a dead/stuck pixel here and there an expected thing for iMac owners?

2 weeks ago I finally decided to order an iMac, despite all of the issues I had been hearing about with the display. I figured that I was going to be one of the lucky ones and have no issues whatsover. I was ordering a brand new machine and it should be fine.After about 30 minutes of getting things up and running, and while a webpage with a good bit of white background was open, I noticed the dead pixel (pixels?). As the question mark shows, I'm not really sure if this is considered one pixel or many. So I figured I'd let the gurus like Hellhammer tell me. The first picture is zoomed out and is of the bottom left hand corner where the dead pixel(s) is. I apologize for the spots around it, that is actually inside the camera body itself I think (Nikon D40x) and I can't seem to get them cleaned off. That's another issue....sigh. The second is a very close in picture of the area. I photoshopped the lense spots out to see it better.Individual pixles are visible. This to me looks like 5 dead ones in a diagonal row.

I just jumped on the Mac train and bought a Macbook Pro 13". There's a dead pixel on the screen. I'm taking it back to the retailer tomorrow. The retailer has a zero dead pixel guarantee on monitors so I'm going to hope that covers laptops too. I just wanted to know how many others have experienced dead pixels on purchasing a new Macbook Pro - i.e. what's the likelihood that the next one I get will have a dead pixel?

I received my new 27" i7 1TB HD on Friday. I was amazed at how fast the shipping was. I'm in the UK and I was told it would be shipped from China and arrive in a week and a half, but instead it turned up from Ireland the very next day! After unboxing it I ran all the tests.. yes, call me a sceptic and tell me I'm looking for trouble! No yellow screen, no grey shadow, no scratches on cds, no dead pixels on photo booth. So far so good. I could swear my Superdrive is making an odd off-key noise when accepting discs, but second opinions tell me it's normal. The Seagate drive can make 'processing' noises every now and then but it doesn't bother me too much. I think in Europe we're stuck with Seagate for 1TB from what I've read here

I have an eyelash-sized dark streak on the center, bottom (dock area) of my Powerbook G4 15". At first, I thought it was dirt, or another external blemish, but if I move the cursor over it, it obstructs the view of the blemish (instead of appearing beneath it.) Also, I have a small, almost white, faded dot which appears to grow and expand larger if the Powerbook is running for longer than 4-6 hours.What is frustrating is that neither show up under screen captures. Is my monitor full of external stains and blemishes which I cannot remove, or is there something actually wrong with my display?
