Is it possible to check the display panel manufacturer of a Macbook Pro 13-inch Retina via a Terminal command?

The command that works on a 15-inch rMBP (and every other Macbook, see question below) doesn't work on the new 13-inch. Blocked by Apple – or do we just need another command?

How can I be sure I'm getting a Samsung-panel retina MacBook instead of the defective LG-panel ones?

Use this :

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

I get LM240WU2-SLB1 for a iMac and LTH133BT01A03 for a MBA (along with "Color LCD" for both)

Just google what you get, for example LM240WU2-SLB1 turns out to be a LG display and LTH133BT01A03 a Samsung display.

*trivia: what the command does is get the hexadecimal string for IODisplayEDID from the IO registry and format then convert it to a string
