    I was able to extract the EDID information for the display to see if we can identify the manufacturer. I used the following command on the Mac to extract the EDID information for the display:

    ioreg -lw0 | grep "IODisplayEDID" | sed "/[^<]*</s///" | xxd -p -r > ioreg.edid
    I then took the file to a Linux system and used the parse-edid program from the read-edid package at http://www.polypux.org/projects/read-edid/.

    The result:

    parse-edid: parse-edid version 2.0.0
    parse-edid: EDID checksum passed.
            # EDID version 1 revision 4
    Section "Monitor"
            # Block type: 2:0 3:fc
            Identifier "Color LCD"
            VendorName "APP"
            ModelName "Color LCD"
            # Block type: 2:0 3:fc
            # Block type: 2:0 3:10
            # Block type: 2:0 3:10
            # DPMS capabilities: Active off:no  Suspend:no  Standby:no
            Mode    "2560x1600"     # vfreq 59.972Hz, hfreq 98.713kHz
                    DotClock        268.500000
                    HTimings        2560 2608 2640 2720
                    VTimings        1600 1603 1609 1646
                    Flags   "-HSync" "+VSync"
            # Block type: 2:0 3:fc
            # Block type: 2:0 3:10
            # Block type: 2:0 3:10
    It doesn't look like there's any useful information in there other than confirmation the display has a really high resolution. Anyone else know of a better EDID parsing tool?

    If you keep playing with this a picture of Tim Cook will appear and he'll have his middle fingers raised and a speech balloon wherein he says "Thanks for your money".

    It appears Apple either modified or had the vendor set the "manufacture" bits in the EDID to "APP".
    That's all you are going to get.

    I'm assuming this is to prevent the massive exchange games people were playing with the 15" rMBP.

    (fwiw, I checked mine. It matches yours verbatim.)
