I am curious how to detect which brand of the retina display I have. I am using the $1999 15" rMBP

Part of me thinks the colors look off, but it might just be the look of the retina.

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

But I just get back, "Color LCD"
 
In order for me to retrieve the full information, I had to install Xcode and the developer tools that come with it. Only after I did that, did the full information on the display panel appear using that command.

I did that, I still just get "Color LCD" as the return.
 
Code: 
ioreg -lw0 | grep "EDID" | sed "/[^<]*</s///" | xxd -p -r | strings -6

Try this string
 
Just found this online. Hope it helps!

Paste the following into a single line in the command line:

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

You will see something similar to this:
LTN154BT
Color LCD

With the first line being the LCD panel model and the second line being the color profile you are using (same as set in your Display preferences). You can then find out what the manufacturer and specs of the display are by googling for the model number, for instance LTN154BT turns up this page indicating it is a Samsung 15″ display running at 1440×900 and capable of displaying a maximum of 262,000 colors.



Please let me know if this helps.

Still returns, "Color LCD" and nothing else.
 
Do any of you know how many people returned ther 1st gen or even 2nd gen rMBPS because they got an LG screen? Apple got smart and disabled this. I guess it's better to not know.
 
I wonder if its an issue with just having the integrated graphics. I have the dedicated graphics and it works fine. The integrated graphics only 15 rMBP and all the 13 rMBP doesn't work with the terminal command.
 
works like a charm, if it asks to install some Xcode components to get it to work, you need to do so.

my output is:
Color LCD
LSN154YL01-A01

Sorry, I didn't realise you were talking about the 13" model, I just saw the 15" on the thread title.

Either way, the string does not work on the 13" model, or the current 15" base model with iGPU only.

Edit: There's one possible way to find out the manufacturer on iGPU only rMBPs mentioned in the Yellow tint on Haswell rMBP 15" thread. It's not certain which values correspond to which manufacturer though, so that may, or may not give you what you are looking for.
