LG is not automatically bad ... it is even the opposite:
Having an LG rev. 2 panel (at least on the early 2013 15 rMBP) is even the better choice than the samsung panel

You know, I wouldn't have believed this last year... But I bought a late 2013 15" MBP yesterday [ LG screen version SJE1 ] and the screen is quite a bit better than my Samsung one on the Mid 2012 MBP.

The whites are cleaner and the colors are more vivid... The whole screen just appears brighter in comparison too...
 
Nice :) Not everyone has one of those, though. I should see if I can get a hold of a macro lens and attempt something similar. I got somewhat close with a 70-200mm at 200mm but I had to stand back a few feet.

Just get some extension tubes. I use them on my 50mm and can take uber close up shots.

You can't be sure it's an LG panel, though. It may be Samsung.

I believe I have an LG screen on my new Haswell rMBP, screen looks really good!

I had a Samsung with a very bad Yellow tint, replaced it and got an LG screen. Everything is perfect now!
 
Late-2013 Haswell rMBP13 /8/512

Manufacturer: 0610 (as everyone)
Model: A018
Manuf. date: CCD71000

Unfortunately there was a small bump in the bottom case, so I called Apple to mention it (to prevent denied warranty in the future), but they ended up sending me a replacement machine :/

FWIW the screen was fine after marco.org 10 minute checkerboard test (remember to look away to persistence of vision problems)

Due to the dent that was present on the bottom case after delivery, I was sent a replacement - this one has:

Manufacturer: 0610 (as everyone)
Model: A020
Manuf. date: CD238700

The sub-pixel layout is the same (!).

The manuf. date from the ioreg (bytes 33-36):
0417

The A020 display is more even (less splotchy), warmer colour temperature
The screen seems more prone to IR though - after the migration assistant (extreme case of being on the same screen for an hour+), both my A018 and A020 showed IR, but the latter took longer to fade, and I could read the text.

Overall I would say that both screens are fine though.

The indentical sub-pixel layout (based on my quick peak with a micrscope, too much hassle to get a good photo) is interesting - perhaps both the A018 and A020 are from the same manufacturer?

I couldn't agree more. My 15-inch early-2013 had an LG-rev 2 on it and it was stunning. So stunning actually that when I brought home my 15-inch late-2013, I couldn't even look at the Samsung display.

I had to exchange it 3 times to be able to get an LG display instead.

The first Samsung panel was yellow at the bottom. You could almost see a straight line running across - with my mail app open, messages on the lower half of screen nearly looked greyed out. It was *that* bad.

The Samsung panel on the second machine was even worse. The whole screen was yellow from top to bottom, and the right side nearly beige. Almost looked like the backlighting was dimmed on one third of the display.

The third one, finally an LG. Perfect white point. Perfect gamma. Amazing color saturation. Whites look like snow and blacks are incredibly deep. Ran the IR test for 20 minutes on full brightness after making sure to run the machine for a while. Nothing wrong here either.

I personally don't agree with people saying that a uniform yellow screen is acceptable and can be fixed through calibration. Calibrating reduces brightness significantly on an IPS panel. I'd take the uniform yellow over the uneven yellow spots any day of the week though but this wouldn't be really true to what my eyes see as 'white'. Especially next to my TB display that's a tad on the cold side.

In the end, when you're lucky enough to get a good LG panel, you get a much more accurate screen. Good Samsung panels with no yellow spots and no darker areas due to uneven backlighting always look off to me. They don't look as crisp and I can really tell from the naked eye which one is which — I could almost skip the terminal command.

Should I be worried about my LG-IPS ghosting in the future? Maybe. Unfortunately, the same applies to everything under the hood. Should I be worried about my dGPU, SSD, logic board? Potentially.

Heck, my 2008 iMac showed some signs of IR after a couple years. If ever the problem arises in a year or 2, I'll take care of it with AppleCare or my American Express extended warranty. I don't want to make myself sick over an issue that I *might* experience at some point in the distant future. Most likely by then, I'll have another rMBP, IGZO technology will be further improved and available within the lineup. (Which by the way, like a member mentioned in another thread, isn't free from defects either. Google 'yellow tint iPad Air' and have a blast.)

I also think that people need to realize that by taking a magnifying glass up to their screens, they will find the dead pixel they can't see or the darker spot that's normally unnoticed. As long as my naked eye can't see, I'm fine with that. I was bothered by the yellowing, it took a couple tries but I found the 'perfect' one that satisfies my eyes at a normal distance of operation. Now that I have, I'd rather enjoy my awesome machine and worry about something else in the meantime.

And there's also that 1% of my being that feels really great about using LG vs. Samsung. :)
 
I have two 15" Retina MacBook Pros on my desk tonight. One is a mid-2012 model, with Samsung screen, owned by my employer, which I've used for about a year. The other is a late-2013 "Haswell" model, with LG screen (2JE1), that I bought for myself, and which I've had for about a week. Both are max-spec units with external GPUs. Neither is currently showing image retention.

With both using Apple's default profiles, the Samsung screen seems to have a slightly warmer white point than the LG. But I would not describe it as yellow. The difference is subtle. The Samsung runs brighter than the LG: their max values at white point measured 331 and 286 cd.

I calibrated both machines with Spyder4Elite, targeting 2.2/6500K. After calibration, the displays appear essentially identical.

Both look terrific.
 
Calibrating reduces brightness significantly on an IPS panel.)

That's not what I am seeing. On the two Retina MacBook Pro units that I described in the previous post, calibration at max brightness to 6500K reduced the output from 331 to 318 cd (for the Samsung), and 286 to 270 (for the LG). Calibrating for native white point would produce even higher output measurements. Bear in mind that these output levels are really bright and might be useful for working in an environment with really high ambient light levels. But professionals doing critical photo editing usually work in darker environments, with monitors calibrated and set for much lower levels, typically 80 to 125 cd.
 
Received my new Macbook Pro (BTO) this afternoon.

Model: Late 2013 13" rMBP
Specs: 2.4/16/256
Screen: A018
Screen Build: 3016

Passed IR test (10 minutes), has even colour.

I am 99% sure the screen is a Samsung. The screen colour/tone is almost exactly the same as my 2012 15" rMBP. My partner has an older 15" with an LG screen, and it is definitely more blue/cooler than both (i.e whites are whiter and brighter).

To be honest, I kind of regret selling my 2012 15" rMBP. Thought I wanted a smaller sized notebook, but now that I have it, I am not sure if it is too small. If I can't get used to it, I will just order the top 15" rMBP.

EDIT: Getting used to the 13". Don't need the power of the 15", very happy with the 13" (easier to use in bed), I will probably keep for sure.

I wish IFixit would do a screen teardown on the 13" rMBP just like they did last year on the 15" rMBP, which revelead the brand of the panel as shown below:

LG%2520Display.jpg


As you can see below, the display was an LG SJA1 (LP designation):

LG%2520Closeup.jpg


With such a teardown on a 13 inch we could see the manufacturer of the 13 inch panel (LG or Samsung) :rolleyes::rolleyes:
 
Does anyone know if these displays use PWM? (0000A018 here). Might be getting a bit of eye strain but not sure yet if a coincidence.
 
seems like LG

i got my rMBP 13" a few days ago and mine is
Man : 610
Model A020
seems like LG but everything is good until now ...
so i don`t think LG is always bad tested with the tested earlier in this post and succeeded it without even yellowish colour i guess.
 
I noticed image retention once yesterday when I was shutting down, I could see a faint image of my desktop background. I just performed the test posted earlier in this forum and my screen passed so I'm not sure what to think at this point.

It wasn't IR. Look it up in the forums, it's a visual effect (or deffect) of your MBP saying byebye. No worries.

Just posted this another thread but it might be helpful here?

Went to an Apple store near me earlier tonight.

Two models of 15-inch retinas on display. One was an LG (A019) and the other a Samsung (A022).

All models of the 13-inch retinas on display had the A018 panel. I don't know if it's an LG or Samsung. Anyone?

The 13-inchers looked pretty color accurate as they nearly matched the color temp of the new iPad Air retina display.

It's true about the LG 15-inch model looking better then the one with the Samsung model. Thought this model at full brightness didn't look bright enough?

It seems that this issue of yellowing isn't actually yellow but more of a push of magenta in my experience. Whites on A022 panels look dim & brownish in comparison to an iPad Air. I could see how this can be interpreted as yellow though.

While some people are having yellow areas which may in fact be yellow (I don't know, didn't see it on either model).

Yes to the eyestrain (A018). I thought it was weird as I never had a problem with eyestrain on my 15" rMBP...

It's important to differentiate between yellow and simply warmer than a prior display. Some people comparing to cmbps notice this. Regarding calibration, part of the problem is that you have no way to address the underlying hardware directly. I mention this constantly. Perhaps I should make a calibration faq thread complete with sources when I have a large block of time.

I'm wondering if both A018 and A020 are Samsung, considering there's two Samsung panels in that list above. Supposedly there's a A019, but that may be a 15"?
