How to Know the Make of Your Retina Display: Samsung or LG?

Submitted by str on Mon, 08/27/2012 - 12:34

Image retention and burn-in issues are widely <a href="https://discussions.apple.com/message/18669644#18669644">reported</a&gt; with the new Retina displays of MacBook Pro. Generally, it seems happening with displays manufactured by LG. While displays made by Samsung are OK. Samsung display are also brighter, and seem to display colors with more accuracy.

How to know the make of your display installed in your MacBook Pro?

Open terminal and run this command:
<code>ioreg -lw0 | grep \"EDID\" | sed "/[^<]*</s///" | xxd -p -r | strings -6</code>

If your display code begins with <code>LP</code> it's an LG display :(
If your display code begins with <code>LSN</code>, you can celebrate as it's a SAMSUNG dislay.

So what you got? Samsung or LG?
I'm having an LG one :(
There is no ghosting or image retention problem but you are right, the display is little bit dull compare to Samsung as I compare it in the Apple Store here in New York. I'm not deciding yet if I will return this or not, as without considering LG vs Samsung display, this is the best display I ever used.

I bought my Retina MacBook Pro in US Online Store as BTO. It took more than 2 weeks before I received it here in Qatar - you can't imagine how long that waiting and worrying in case I receive LG panel... When I received it, I check immediately - Samsung!

You better return and exchange yours.

Thanks Aileen.

keeps cutting off the last part... I realized that using the Filtered HTML text format was doing it.

Here's the correct command:

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

Thanks, thats the only one that worked for me too. I had a LG screen with major image retention :(

I went into the Apple store last week and showed them the test found on the link in the comments above. This one... http://www.marco.org/rmbp-irtest.html
I said that after paying a lot money for a fully configured rMBP it is unacceptable to have a screen perform like this.

A week later I have a laptop that has had the screen replaced (complete from the hinges up). I am glad to say it is now a samsung screen and it was all under warranty. The laptop was 11 months and 18 days old when I took it in haha.

Thanks Apple :)
