    I scored the Samsung SSD - yes!

    Can't tell display.

    All the commands I googled yield just Color LCD.

    What's the new way to tell.

    run this line is the Terminal.app
    ioreg -lw0 | grep IODisplayEDID | sed "/[^<]*</s///" | xxd -p -r | strings -6
    If output doesn't prefix LP then it's a Samsang screen,otherwise LP:)

    Here it comes again.. And why is the manufacturer important? Is the display malfunctioning? I used to think we're past this madness.

    Slight yellow tint on the bottom half of the screen but I can live with it

    My dGPU model is an LG screen. I haven't properly calibrated it yet, but no issues.

    If anything I feel LG as a whole makes a better display than Samsung. Typically most of Dells displays are LG, I believe most of Apples larger screens are too?

    Cause the bigger your SSD the faster it read and write..
    My former ME293 is the same result as yours.

    Are the Samsung screens brighter than the LG screens? My 15" Mid 2014 retina screen, which is LG, feels a bit dim.

    Are LG screens still problematic and to be avoided, or has the manufacturing process improved?

    Yes I ran that command line in the terminal before. It asked to download X-Code so I did that. But it still comes up with this.

    @.`0 6
    Color LCD

    So as it does not prefix with LP its a Samsung screen. Not that it matters but still.

    Wrong grep?

    (Does some quick Googling for the command-line stuff...)

    Different "grep" value?

    Code:
    ioreg -lw0 | grep \"EDID\" | sed "/[^<]*</s///" | xxd -p -r | strings -6
    This gives me a line that starts with LP, which is an LG display. This MBP has serious burn-in but it's work-issued so I don't worry about it.

    Even if I'm running gfxCardStatus and have the discreet 650M disabled? If true, sorry.

    If I finally broke down and bought an IrisPro-only model for myself I would've know this... ;)

    On current base model rMBPs there is no easy way of finding out the manufacturer (you could take the display assembly apart and check the label on the back of the panel, but you'd most likely crack the panel in the process).

    The method you tried reveals the serial number (edit: and model number of course) of the panel on rMBPs with a dGPU. On models with iGPU only, all it returns is the name of the current color profile, which is in no way useful in determining the manufacturer.
