Here's a thread I came across just now: http://forum.notebookreview.com/app...-macbook-air-inconsistent-screen-quality.html At the same time, I just had a quick side by side comparison on my LG versus my friend's Samsung. I noticed right away how evenly lite is the backlight on the LG display, the Samsung has noticeable gradients on the bottom. Also, the colors on the Samsung is more pumped compared to LG, but when put them side by side, especially when watching a video, the colors on the LG is much more natural while the Samsung looks dull. I believe calibration will help to certain extent though. As for the viewing angle, they're actually surprisingly close. I'd say both are equally good, at least no noticeable difference during normal use. At highest brightness setting, it seems that LG is slightly brighter. I did the pixel crosstalk/walking test, interestingly Samsung pass all tests while the LG flicker on one of the test, in fact, pretty badly on highest brightness setting and when viewing the picture setting in large area. This is probably the only "defect" on my LG display, and some of the website exhibit this problem but due to the fact that nobody actually use those kind of picture in large scale (usually just as background, often much less than 50% of the screen), so there isn't much chance to distract you from viewing those websites. My opinion? Both are equally good (or bad). At the same time I also believe there're good LG and bad Samsung, and vice versa. If your display shows problems, exchange or replace the display. Otherwise you may end up with worse display even if the terminal pop up the magic display model number. So when you test your brand new MBA's display, all you need to do is to make sure you check the fundamentals just as you would on any other displays - even backlight, 100% healthy pixels. No more, no less.
