Answer:
Answer:

Go to your Applications folder and launch Terminal. Paste in the following and hit return:

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

Look at the beginning of the second line to see which manufacturer made your display. If it starts with LP then you have an LG display. Samsung displays start with LSN

Color LCD. There is no LSN and LP in the second line. What does this mean?

It probably means you have a 13" screen; that terminal command only works with the 15" screen.

It seems the strings location has changed. Type this one instead :

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


I run this on macbook air 13 and here is the result :

?????????x??WT?'"PT?"??P?00 6??LSN133BT01A02?Color LCD

PT?K???qO?@??V^???)P0 5UP!?


You can still see the manufacturer code LSN or LP on the first line right before "?Color LCD".
