Steve Jobs holds up the new unibody MacBook Air durring its unveiling.
It was sometime after the MacBook Air's refresh this year that it was discovered that the MacBook Air was shipped with two different models of memory. Some were shipped with speedy Samsung flash memory and some were shipped with slower Toshiba flash memory. The speed difference was pretty noticeable and could be easily discovered using the free disk speed test from the Mac App Store. But flash memory isn't the only component of the MacBook Air that Apple had mixed feelings about.
Apple has been shipping recent MacBook Airs with not only mixed flash memory companies but also with separate displays as well. Some of the ultra-thin notebook's displays are produced by Samsung while some are produced by LG. Both screens are of high build quality and both will be good enough to make the user happy with the end product, but there's definitely a difference between the two that is noticeable when they are put side by side of one another. The Samsung screen screams colors while the LG screen is a little bit flat in color. That's not really a hardware problem, you can actually bring the LG display up to Samsung snuff by installing and activating a color profile on your Mac. This can be done from system preferences and you'll notice the sharper color immediately. Due to the nature of color change, you may feel that the color profile you install appears to be a little bit more green than the original. Anyone who's used the Application F.lux knows what it's like to have their screen color manipulated for the first time.
Directions for finding your display type and tweaking it, courtesy of OSX Daily:
Step 1. How do I know if I have an LG display or a Samsung display?
The process for discerning what kind of display you have is easy. Open up a terminal window and type the following:
Hit enter, and look at the result. If it begins with an, "LP" then it's an LG screen. If it doesn't then it's a Samsung screen. If it's an LG screen your result might look something like this:

Begin by downloading this color profile to your desktop. You can download it anywhere but the desktop is recommended so that you can find it quicker in the upcoming steps.
From the Finder menubar, navigate to Go>Go to folder>/Library/ColorSync/Profiles/Displays/
Once in that folder, move the color profile that you downloaded to your desktop into that folder, and enter your password to authenticate the moving of the file to that folder.
Step 3. Applying the color profile.
Now that you have the color profile that you need moved to where it needs to be, you can open up System Preferences>Displays>Color. In the Color tab, uncheck the option that says, "Show profiles for this display only" so that you can see more options. You will see, "Color LCD" above the horizontal rule and you will see a second, "Color LCD" under the horizontal rule. Click the second one to apply the changes, you will see a color difference right away.
Why did Apple use a mix of LG and Samsung displays? Who knows. Maybe Apple struck a deal that could have saved them some money, or maybe they have a little bit of a stiff with Samsung. After all, this is the second time that Samsung has been replaced by another company in Apple's MacBook Air lineup.
I'm curious to see just how many people have LG displays and how many have Samsung displays. Leave a comment below! I have a MacBook Pro from mid 2011 and it has an LG display. So this Terminal test can be done from any Mac.
