Test for rMBP screen manufacturer

My last two, one LG and one Samsung, both had dimmer backlighting in the bottom left corner. I have seen at least one picture, however, of someone else who has a dimmer display on his bottom right corner, though. It seems to be careless manufacturing.

Hmm it seems even at "perfect" viewing angle, which would be looking at the screen at center straight on with screen slightly tilted, theres a slight loss of light in the corners. It's like when looking at the screen from the sides you will notice the screen will be dimmer than looking at it from in front of the screen. So what I'm saying is there is no viewing angle that does not result in a loss of screen brightness. I'm not an expert but I guess it's the result of some kind of anti-glare filter being used but I'm not sure.
It's like those really cheap TN panels that show a negative image or whatever if you tilt the screen too far back or it would be washed out if it was too far forward but you would always see a partial negative or washed out image because it's just really cheap quality and there was no perfect viewing angle.
It's still not nearly that bad with the retina screen. I guess if it were brighter it would be unnoticeable. It just bothers me.
When I returned my rMBP today at the Apple Store, they weren't even interested in hearing the reason for the return.
I don't know if that means that they are just shipping everything back to China, doing the same checks that failed the first time (in my case: yellow LG panel), and reselling the same brick to some new victim?
I don't think that all those $3k-$4k machines will go straight into a landfill ...
I am disappointed that Apple doesn't try harder to address specific issues based on customer feedback.
I originally thought so, too, but on closer examination, if you look straight-on at the corner(s) that are darker, they don't improve that much. If you look straight-on at a dark corner, and then look straight-on at a corner that normally appears normal/brighter, you will see that even when viewed straight on at the corner itself (rather than looking straight on at the center of the display), it is still noticeably darker and off-white.
At least, in my two cases so far, that has been the case. And the left corner is significantly and obviously darker than the rest of the display...it's not like all corners look equally dark to me when viewing the screen from the center.
I'd be surprised if these aren't the units that end up on the Apple Refurb on-line store, actually.

So if you can run the following command in terminal it will tell you who the manufacturer is:
ioreg -lw0 | grep \"EDID\" | sed "/[^<]*</s///" | xxd -p -r | strings -6
What happens if use it non-ratina display macbook pro?
ioreg -lw0 | grep \"EDID\" | sed "/[^<]*</s///" | xxd -p -r | strings -6

Being able to clean the screen with a cloth and light pressure is a requirement of a notebook screen. If the screen is too fragile to do basic housekeeping then it is faulty, simple. The Apple website even has instructions on how to clean with a cloth, so they expect you to do it.
In the UK at least we have laws that cover things like this, about things having to be fit for purpose. And cracking whilst doing standard cleaning is not fit for purpose, so you are OK.
My samsung display got two hot pixels after 6 days of usage. So tally that up with 3 samsung displays with stuck pixels, 1 LG with IR. I swear to god this is the most frustrated thing ever. Going for ANOTHER return now. Both screens can have issues, it's just the luck of the draw.
LG screen ...
new unboxed retina day 1
no dead pixels / no backlight bleed / ghosting not apparent (but ghosting test not done)

LG screen here. Just picked it up in the Apple Store today... drop dead gorgeous. I have it right next to my old 13" and everything looks blurry on it in comparison. No yellow tints, ghosting or anything else that I read about online.
the Apple website claims that the display of rMBPs is an IPS display, however Samsung uses their own proprietary Super-PLS technology. How can Apple claim this fact and use a different type of technology for their screens? Seems wrong to do.
Based on online reviews PLS(Samsung) technology is superior to IPS(LG). Seems crappy to dual source a part that is one of the selling features of the machine. It's like having two different suppliers for video cards.
I bet someone will sue them for misinformation, haha

the problem lies within what constitues "light cleaning". whether or not this user applied unreasonable force on his screen is really his word against theirs. As i said, unless hundreds of reports are coming in about screens cracking its more than likely not an issue. I have sympathy but really nobody knows if this guy used excessive force or not. im sure MANY people have been cleaning their screens since the launch of this and ive not heard any reports of it cracking when being cleaned. thats all .
Well I got tired of waiting for the Apple online/phone support to help me out so I went to my local Apple store here instead of dealing with the whole shipping nonsense.
I returned mine and wen't full-out, purchasing a 2.7/16/768 configuration. One because it's awesome and I love this thing, and secondly because I had a hunch that if they are using less Samsung panels for whatever reason, that the highest-end model would have to have a better chance of shipping with one. Well, on the first box open it turned out to be a Samsung. Whether or not this was just plain luck who knows, but I'm happy to say this screen is flawless and no IR on it.
As far as the quality difference in the sharpness and contrast etc. I don't think it's any better whatsoever than the LG. They both produce extremely high-quality images with good colour reproduction on both of my machines - especially for a laptop display. It's quite impressive. So, if there is indeed a slight issues with a bunch of the LG screens I'm sure they will fix it; and I wouldn't hesitate in the future at least, to keep a computer with an LG panel because you're certainly not 'missing out' in image quality in any way after having both and being able to compare.

Only difference I've noticed is that there is no longer the blemish
I think both displays are amazing I just don't know about the blemish that I had experienced. It was right of center in thee lower third and was noticeable enough to cause issues when playing in aperture with photos or drawing attention to itself within pages. Don't get me wrong I'm as much as a Samsung guy as I am a Mac guy (apart from actual computers, tablets and phones) all my home theater equipment is Samsung and all my printers so I have come to appreciate the peripherals Samsung makes as well as their displays. I think it's just the roll of the dice on the part of both vendors and possibly an issue more towards assembly (pressure point cause blemish?).
Hopefully things will settle out before apple has to do a mass recall and switch all the displays out to save face (it seems like a decent size issue even if not everyone is experiencing faulty displays one way or another).
Light cleaning was light cleaning. There was no question that it was a hardware problem. This was the first machine to show up at that store's genius bar. They originally said it would be 10 days out of service (video card went bad too, then the creaking) because they didn't have parts since the rMBP is so new. I explained that I can't go without a computer for that long, since I rely on it for freelance work and since I bought it so recently, they eventually swapped it out. The only person to say "you were lucky we're covering it" and "you can't cut other customers in line (to dispatch it?!) was the manager, who seemed to be having a bad day in general because they were hours behind on appointments and the power had gone out.
I'd rather go to the dentist than the Apple Store, any day, at least they give you an IV of Valium. I think the Genius Bar would be 10x as profitable as a real bar. Not one person was a happy camper in that store today, and I know that I could have really used a cocktail.
BTW I'm LG again. It doesn't creak anymore though.
