Test for rMBP screen manufacturer

Question for the people who are running the IR tests...do you actually notice it when using the machine?

I might have a Samsung display (Not sure as I can't run the command on the 13") but in using it over the past couple days I haven't noticed anything...I do have the display set to sleep after a few minutes of inactivity though.

with normal activity no, you wouldn't notice it. but, if you use retina screen as for instance secondary display where one window stays open for a long time in the same position, you may see it on normal wallpaper as well.

it's only a personal choice, if you accept it or reject it and ask for replacement.
 
Well I had an LG display but I dropped my rMBP and shattered display and Mission Repair replaced it with a Samsung. I can tell a difference in that whites looks much whiter and the screen as a whole is much brighter. Never did all of that image retention testing....

How do you find out the screen brand on a 13" rmbp? I just bought one and all I get when I run the above long command is:
When I run the short command I get:
Code: 
$ ioreg -lw0 | grep -i "DisplayVendorID"
    | | | | | |       "DisplayVendorID" = 1552

I also get 1552 on my new rMBP 13", hope this is a way to find out what panel it is. I tried testing for IR and saw absolutely none. (I didn't check the black/white squares but I left the Apple homepage on for 15 minutes with the big black "iPad mini" text on a white background, and then switched to a grey background, didn't see any ghosting of the black text).

It would be interesting to see what others with a 13" get from this command, and whether they have IR or not.

Also 1552, and absolutely no IR.

The screen is gorgeous.

1552 on my new 13" retina as well, absolutely no ir on this screen:D
 
For some reason the Terminal command doesn't work for me. Nothing happens. Through System Preferences I discovered that my screen was made by manufacturer "610" whoever that is? Samsung? (Hopefully?) If anyone knows it would be greatly appreciated! :D

I've run this test on both an LG and a Samsung 15" Retina MacBook Pro and unfortunately both report back 1552, so it's likely to be the case on the 13" too.

I did the test on my used (bought it off someone who had it since August 2012- over 6 months). Left a finder window on for over 1/2 hour and no IR despite being an LG panel.

Paint me naive but isn't image retention or persistence expected on IPS panel. Even the best IPS panel from NEC suffers from IR. There are simple steps you can take to prevent IR and in all but a few cases of IR are permanent.

Image Retention is to be expected on an IPS panel, but only after a static image has been displayed on the screen for several hours. The Retina MacBooks show retention after only a few minutes. Apple is the only manufacturer to consider this normal behaviour.
 
Just picked up a new 13" rMBP…

Samsung display with a Samsung SSD. All is good.

15 in. Retina - Terminal command works

I'm beginning to think we're talking about different Terminal commands…

There is one listed here that's the "short command" if you type for Samsung panels returns a "1552" which according comparison to a 15" rMBP that works with both commands… And with the power of deduction, I conclude the 13" rMBP I purchased has a Samsung panel just like the 15" rMBP I have.

And I feel better that way and that's all that matters. ;)

Haha OK, that's cool. This ****'s been blown out of proportion to begin with anyway (not to say there is a legitimate issue out there, just not as widespread as reading an internet forum would have you believe).
 
I've had my 15" rMBP for almost 3-mth, but I've only just realised I have the inferior panel.
So pissed-off, I hope I'm not given the run around with regards to a replacement...
To spend a fortune & be given a inferior panel* (no matter how marginally) in return, is pretty poor business practice.
I understand the logic/logistics behind why they often do this, but it doesn't change things IMO.

*by most accts I've read so far, & not just in terms of burn-in

I checked by rMBP with an LG screen (based on the script) with this test:
http://www.mitchmalone.name/retina-test/

I run the 10 minute test (below) on my machine, which according to the script has an LG screen, and didn't notice any image retention.

My previous basic 2.3 rMBP had an LG screen and did showed IR on the test. This machine was sold by Mac Mall in December 31st and Apple Care reflects December 8, 2013 as the warranty ending date (now is December 8, 2015 since I purchased Apple Care) so apparently is a late 2012 rMBP production.
I know not every LG shows IR, apparently mine is one of the good ones; if something goes wrong in the near future, I'm covered until 2015.
