Terminal only works if you have a 750M.

Open Display preferences > Open Color profile > Scroll to the bottom ... look at Model number

A019 = LG​
Other fellow MR posters: please include your model numbers for LG and Sammy

The most popular way is to use the following code in Terminal:

ioreg -lw0 | grep "EDID" | sed "/[^<]*</s///" | xxd -p -r | strings -6

If the output on the second line begins with LP then you have an LG display, if it begins with a LSN then it is a Samsung display.

Alternatively, you can use the following command in terminal:

ioreg -lw0 |grep EDID |grep 4c534e

If it gives an output then you have a Samsung display.

ioreg -lw0 |grep EDID |grep 4c50

The previous command will search for the LP hex string, and so if you get output then you have an LG display.

If the screen is yellowish and a bit dim even at full brightness, it must be a Samsung but most owners of the 13" retina have an LG screen to include myself.

I've got a yellow and dim LG LP154WT1-SJE1 (A019) on a 15" so not all LGs are bright and clear unfortunately. But most reported yellow and dim screens seem to be Samsung.

So A019 = LG and anything else is Samsung?

If you have a 13inch. You can't tell if that model is Samsung or LG. At least for now we don't know.
Then how to know it for retina rMBP 13" (haswell) ?
I have used both commands in terminal and got nothing :(

Maybe I were doing something wrong?

I'm in the same boat as you. Actually all of us with late rMBP 13' can't know what screen we have. Only 15inch rMBP can use the command in the terminal to find out which one they one.

Nevertheless, there should be the way to know it :(

Just received my 13" 2.6 16GB 256SSD from Macmall... Looks like I got a Samsung panel!

Manufacture: 610
Model # A020

don't be too happy yet, this info isn't confirmed, but only assumed by MR members...

no one knows how to determine it for the 13's. there are currently A018 and A020 display models floating around.

If you have a 13inch. You can't tell if that model is Samsung or LG. At least for now we don't know.

Actually all of us with late rMBP 13' can't know what screen we have. Only 15inch rMBP can use the command in the terminal to find out which one they one.

So my model number is 0000A020. This is Samsung, yes?

I think the command that runs on the 15 inch only works on computers with dGPU (which the 13 inch does not have); that would explain why the new 15 inch retina without a dGPU cannot run the script neither (as I have read here by others). I have home two 13" 2013 rMBP and screen manufacturer are 13 and 14, so no idea if they are Samsung or LG (I did the IR test on mine and was able to saw some IR that lasted less than 5 seconds, perhaps I do have an LG :mad:)

It doesn't matter that people posted their screen model number and asked if it was Samsung that does not say anything..

There is currently no way to know as of now with the 13".
