Does anyone's RMBP have dead pixels?

We've had iPhone 2G, 3G, 2x3GS, 2x4, 4S, iPad 2 in our family. Not one has ever had a dead pixel.
I ve tested my friend's MB Pro early 2012 just yesterday and it also had no dead pixel, so hopefully Retina wont have any... 🙂

Even if it had a dead pixel, you shouldn't even be able to see it on a retina display, correct?

I had two single red pixels on my iPad retina screen. It was very obvious, surprisingly and drove me up the wall. Needless to say, I got it swapped out. I hope there are no yellowing issues with mine more than anything else.

Germany here.

Had a Base Model with dead Pixel in Black, as for the Resolution
of Retina this must have been a bunch of Pixels.

Returned it to the Apple Store and got it exchanged for new one,
without any problems. 🙂

Haha, great eurovision entrance and German capital letters gone rogue there. Love it.
 
i'd assume its alot harder to spot a stuck/dead pixel on a retina. Could just be a case that people have not noticed. Its a lot more obvious on displays with low res.

If each quadrant of the panels has .1% chance of having a dead pixel.

P(No dead pixels) = .999^4
!= 4*P(No dead pixels in one quadrant)

As you can see that as resolution increases the chances of getting a faulty panel increases exponentially. This is why they can pump out millions upon millions of high density LCDs in the <4" form factor but so high density displays that are larger.

This isn't an entirely correct formula. I learned in my IC fabrication class that if this model was true, there wouldn't be a semiconductor industry because the failure rate would be so high. Instead, you want to take into account cluster effects (when there are failures, they tend to occur in similar space or time regions). If I can find them, I'll dig out my notes and give you the more accurate formula later 🙂

I would expect a $3.5K laptop screen to be pixel perfect, otherwise, it would be ridiculous.

Technically its not a $3,500 laptop screen. I am certain that the screen actually costs much less than $1,000. That same exact screen comes on the low end MBPR so one could argue that it is a $2,200 laptop screen.

1st dead pixel on retina. yep
Click to expand...

Bought my rMBP last week, pixel perfect. My dad decided to buy one for work yesterday and I noticed a dead pixel while installing software for him, check out pictures below. I'm headed to Apple tomorrow to get a replacement. A $2,200 laptop should be flawless!!!

Pics aren't the best, i took them with my iPhone but you can clearly see it when viewing a white page.
The cursor is not where it is, it's toward the bottom left of the screen

No! A dead pixel bright red on the middle of the screen is surely noticeable! when I pay so much for a notebook it must be perfect, on the first 14 days ( here in Italy you have 14 days to return it on an online purchase) i always deeply test it!

A dead pixel could even lower your resale value, check your display and if it has one return it.

As other people already said: I could accept a dead pixel on a 400$ notebook, on a 2500$ no way...

This is my opinion.

Sorry for my English 😉

It wouldn't be noticeable with the pixel density on the RMBP screen. At least I wouldn't notice it.
 
Just ran a few dead pixel tests on different colored backgrounds and after vigorously scanning top and bottom, I have no dead pixels! (or at least none perceivable to my eyesight)
 
your completely right that looks the same as the pic i posted.

after ordering my rMBP last week and having to wait 4 weeks for a 16gb ram/512hdd i would hate to find i had to send it back.

good luck fellas

It must be pressure damage, dead pixel looks completely different

I can see both a dead pixel AND pressure damage on that picture (the pixel is to the left of the large white spot).

The pressure damage thing seems to be a wide-spread issue. I hope this is from the manufacturing process and not something that will develop gradually on all Retina MBPs. I remember a very similar issue with 17" and 15" powerbooks (or early MBPs don't remember) several years ago. Same kind of white blotches showing up on a huge number of units.

In this case, my guess would be that there's a problem getting the inside of the unibody display case perfectly flat. If you fit the panel on a surface that's not perfectly even, it'll develop those pressure defects.

Interestingly, I just had the same thing happen to me on an HP Envy Spectre - got it exchanged and the exchange unit had the exact same issue. Returned it and ordered the Retina MBP - just to read here that it, too, has issues with pressure marks on the panel. Mine's ok so far (knock on wood) - just hoping this isn't something that just pops up randomly (as it did with the old PBs / MBPs)
