    I keep reading threads about yellowing on LG and/or Samsung displays on the rMBP...

    Please excuse my ignorance but how do I find out which one I have? I just bought this thing 2 days ago and it's gorgeous.... so I wanna know whether I need to email LG or Samsung or someone else to thank them for their excellent product...

    Thanks!

    type this into terminal:

    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

    That isn't working. I am getting "Color LCD" which doesn't tell me anything... like this.

    TRC-MacBook-Pro:~ TRC$ ioreg -lw0 | grep "EDID" | sed "/[^<]*</s///" | xxd -p -r | stri-6s

    Color LCD


    A common problem?

    I've also tried some of the other commands listed in that thread and they return garbage... like this...

    TRC-MacBook-Pro:~ TRC$ ioreg -lw0 | grep "EDID" | sed "/[^<]*</s///" | xxd -p -r

    This Terminal command will only work on Macs with discrete GPUs.

    If your Mac does not have a discrete GPU, the command will not work.

    Thanks for the tip.

    So is there any other way to determine which display I have?

    Yes.

    In System Preferences, go to Display. Under the Color tab, select Color LCD and click Open Profile.

    Scroll to the last section where the description says 'Apple display make and model info'.

    Post back the model.

    You said its gorgeous??

    So what are you worried about the machine is fine use it and forget all this nonsense, the vast majority of rMBP's sold are fantastic with no issues the make of the screen is immaterial if it is working and you like it....

    s

    0000A019 which according to a forum search is LG.


    I'm not worried about anything. I was just curious.

    This machine kicks ass. Thank you Apple.

    Thanks for the help guys!

    I have the same screen and it is amazing. I am still stuck on the gee-whiz stage and keep loading new wallpaper. :cool:
