Hey all,

There has been a command-line method for checking the model # of the LCD in the system that has been floating around for a while, and as people have been trying it on the new Retina MacBook Pro, they've been discovering that it only ever spits out "Color LCD" as an identifier.

I've determined that if you modify the command slightly, you can get the system to give up the model number of the display. Simply replace the IODisplayEDID part of the command with \"EDID\" like so:

Code:
MacBook-Pro:~ root# ioreg -lw0 | grep \"EDID\" | sed "/[^<]*</s///" | xxd -p -r | strings -6
Color LCD
LP154WT1-SJA1
DCN2253002BDMJ0AE

My guess is that all of the displays currently shipping on rMBP are the same make and model (LG Philips), but it would be interesting to see if anybody else gets different results on their system.

iFixit also found evidence that the RMBP they tore down had an LG display. I would be surprised if there were more than one manufacturer at this point, but I guess it's possible.

FYI, I ran into another Retina LCD model # while trying this on a display unit at an Apple store: LSN154YL01001.

I haven't been able to determine who the manufacturer is yet strictly from the model: as far as I can tell, there is no manufacturer that uses model numbers starting with LS or LSN, and Acer used to use L until they were merged into AU Optronics, which uses B. Maybe LSN is used in addition to LTN by Samsung?

The OPs model number seems more consistent with LG's model numbering scheme, whereas the second is closer to Samsung's but can't be certain.

LSN panels do seem to be Samsung. Some of the Airs have an LSN133BT01-A01 panel which is Samsung.

Mine's a Samsung. Seems to be slightly better than my last rMBP which had an LG panel.
