For what's worth it. Like another forum member pointed out somewhere. Apple advertise with IPS (In Plane Switching) screen. But in fact only the LG is a real IPS screen.

Samsung isn't licensed to produce IPS panels (IPS technology is invented by Hitachi and licensed to LG).

Samsung makes it's own variant on IPS named PLS (Plane to Line Switching). Samsung claims for better brightness and bigger viewing angles in comparison to IPS. However I suspect it is just their way to make their own IPS panel (copied) but with a slightly different technology and without the legal struggle.

Which one is better/more reliable is hard to say. Personally the Samsung Retina's I've seen where definitely sharper and like you read from a paper so sharp. The LG's where darker, and where the only ones I could provoke the "ghosting" effect on by simply leave a full screen PDF page open for only 5 or so minutes.

In short. The LG is an IPS panel the Samsung is their own technology PLS panel which is claimed by Samsung to be "superior" to IPS.

I am biased myself because I find Samsung screens superior. That said, My girlfriend owns a cMBP hi-res matte with the best (non retina) screen i've ever seen. This happens to be an LG. Totally constant backlight. No light bleed, vivid white and just a picture to look at.

Interesting, my own Retina has an LG display and it `s only marginally down on brightness than my Late 2011 15" MBP, absolutely pin sharp. Personally I believe it is what it is, given that you are presented with a good panel, in that it`s completely subjective: hue, colouration, contrast, brightness, sharpness etc. A good display is a good display whether it suits your taste is a entirely different matter.

Samsung LSN screen. Mine is pretty much perfect.

Wish I checked which screen was in my previous rMBP which had terrible bleeding

However, I just found out and read few postings here about yellow tinting.
I also found that MBPr has 20~25% less brightness compared to other Macbook PRO lines. (because of retina and battery performance reasons etc etc)

I compared my MBPr with my GF's new MBA 13 and there are considerable brightness difference.

I took a picture of MBPr and MBA in the dark at full brightness on both units.
I kind of see the yellowish screen with MBPr but I am not sure if it is due to the less bright screen of MBPr.

How do you check if your screen has yellow tinting? Is there any reference that I can used to test my screen?

Can anyone tell me if I have yellow tint screen?
Looks perfect to me, nice and white on both of them. I wouldn't worry - if you're happy with it then don't even ask these guys what they think

Looks like I got an LG. Absolutely nothing wrong with the screen. Except beauty.

guys, what is the best way to check for ghosting? Anything that could always show it?
I remember 8 years ago testing it in the apple store on those cinema displays and i put the screen background on dark grey, opened safari, left it on for 2 mins and then minimised it. On most it would show the ghosting.
Is it still the same or is there better way to test it?

I have the Samsung and it looks OK to me. If I put on a white screen I can see some color shifting and that the screen is brighter in the lower edge. Doesn't seem like a problem to me.

Has anyone's screen uniformity changed with time? I know my NEC display initially had pretty bad uniformity out of the box, but after some significant use, it became almost perfectly uniform.

I'm going to exchange my LG because of the ghosting issue. However, I went to the Apple store yesterday and compared my rMBP LG screen to the Samsung rMBP that they had on the floor. With both machines set to max brightness and Auto Brightness turned off, my LG was noticeably dimmer and yellowish: it looked dingy in comparison to the Samsung.

I have a LG screen and my partner got one with a Samsung screen.

Comparing side by side, the Samsung was the crisper screen and had brighter whites(completely subjective observation, btw). I instantly picked up on this from the first few seconds of looking at the screen. This was before I even knew there were two different manufacturers making these displays. Running the script confirmed that there might be a difference based on who made the display.

Ok, tested it and yep, I have slight ghosting.

LG and minor ghosting.

Samsung here, ordered from Germany, and I haven't noticed any problems. AIDA64 reports the screen being manufactured in the 16th week of 2011, if thats true, they've been stock piling these things for ages!

LG screen on my 2.3/16/256. Absolutely perfect - no dead pixels, no color tint, no IR. Clearly it's defective.

actally tested my LG with the ten minute wait and DID get some very minor ghosting. question is, will it get worse? meaning burn in.

the brightness and overall quality is great, no dead pixels or backlight bleed. My machine functions flawlessly and id HATE to return this to get either ANOTHER lg panel, or one with backlight bleed.

I dont want to get caught in the revolving "returns door" (what if the next 5 returns are all LG panels?). The ghosting i saw was minimal and probably wouldnt have noticed if someone hadnt pointed it out. i can totally live with it. but not if its going to get worse. I know samsung is using IPS tech in their phones and they have MAJOR ghosting because all their phones on display at BB have SERIOUS burn in.. and thats what im worried about. permanent burns like the plasma days.. so is that a possibility or is this as bad as itll get?

People with LG screens. Try this test out in a dark room with full brightness with video at full screen.

What do you see?

I also believe its just the mindset that makes you believe the LG is inferior to the Samsung.

LG used to make the panels for the 30", 23" and 20" ACD's. Not sure about the current ones but these companies has always worked together to develop newer technologies.

If you read up on the partnerships and the products LG are coming out with now such as the LG Smart Panels TV's which are mm's thin it was because of the combined R&D of Apple and LG.
