    OK campers - we are back to this...Just got my new 2012 Macbook Air 11" i7 256GB SSD/8GB RAM

    I knew immediately that the LCD was a bit flat (or less contrast) as well as some blacks appeared more blue. After checking, I found that my new 2012 Macbook Air has a LG screen. I compared it to my Mid-2011 Macbook Air i7 (which has a Samsung LCD) and the 2011 had more contrast, etc.

    Not that the LG screens are bad or anything, it is I am just use to the Samsung screen I have in my 2011 and do not want to go through the calibrations. Personal choice, Just like the Samsung better.

    You can see what your LCD manufacturer is by doing the following:

    Launch the Terminal (/Applications/Utilities/)
    Copy and paste the following command onto a single line and hit return:

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

    Read the output, you are looking for an “LP” prefix to numbers reported back:
    Color LCD

    If the prefix is not “LP” then you have a Samsung display and there’s no need to use the color profile or to follow the rest of the instructions, if it does start with LP (like the example shown), then proceed

    You can fix up color display on your LG display by using a different color profile. Google it.

    My new 13" Air says: LTH133BT01A03

    A quick duckduck search tells me this is a Samsung panel.

    I returned mine - the LG is not bad or anything, even with color calibration, I prefer the Samsung panal's contrast.

    To each our own...

    Damit, I have the LG on my new 13" air. I knew my screen looked a little off compared to my girlfriends 2011 13" air.

    You guys are so silly. Even among a single panel brand there will be variation. They take commodity panels and implement them into a final design. This includes additional circuitry, backlight (sometimes edgelight), etc. The profile thing is also a somewhat odd way of addressing this. A profile describes physical hardware behavior. They use generic ones. To a degree you're just lying to the framebuffer to adjust the final behavior:p.

    As with my 2011, I have an LG panel and a Samsung SSD. As with my 2011, I'm keeping it. :)

    I assume it used to be only two panels, but there is a third to which is the one I have in my MBA mid 2011. It is an AUO. So the first two letters not being LP does not necessarily imply it to be a Samsung. I do believe the AUO panel is more rare and I have yet to see it on a 13", but have on a few 11's.

    I have no idea though on where the AUO falls in comparison to the other two panels as I haven't compared.

    My 2011 Air had the LG and used it without any further color calibration. I had no problems with it in the long run. The biggest shock for me was that there is such high variance in parts for the same model.

    Ditto, Samsung here as well.

    Oh and it's beautiful :)

    Any problems with uneven backlighting on either the LG or Samsung displays on the 2012 models?

    I have an LG in my 2012 11" Air and I also had one in my 2010 11" Air so I've never tasted the Samsung goodness so don't know what I'm missing and will keep it that way because I did get the Samsung SSD and that thing is benchmarking a lot better than another guy's Toshiba in the other thread on here.

    maybe the 11" use the LG and the 13" use the Samsungs. I have a 13" and will check tonight which screen I have now that I know how to do it.

    on the same note, I am sure I seem some profiles that people have put together to fix the LG screen as mentioned above, any one know where they are so I can download them and try them out?

    oh no.. i returned my mba 2011 because it has the LG screen. my 2012 would be coming tomorrow. Please God, let me have the Samsung screen. Huge color vibrance difference. They didn't want to take back my mba 2011 because they thought my eyes were retarded. but they believed me after I put the LG next to the Samsung (macbook airs of course). They immediately apologized and refunded me. You can immediately tell the LG ones are washed out. I'm not paying the same amount for a less better screen. And if you think i'm crazy, just put an LG next to a Samsung, I am sure you would get the Samsung. I did a comparison at the apple store where I asked customers to point which is better. All said the Samsung was.


    tried it. hated it even more

    I don't know, I have an 11" LG 2012 next to my friends 13" 2012 Samsung and I really don't see much difference at all. Have people confirmed the problem exists still with the new 2012 models?

    Having the AUO panel too, I'd love this question answered.
