I have a LG screen but I dont experience the flickering from the green header...


It's called cross-talk. Common issue with LCD's. How are the Samsung's out there?

Check this out ... urghh!

After clicking this link all I remember is waking up from a seizure.


All screens needs to be calibrated as was stated. Its the same with buying an HDTV. Once you do so your eyes gets used to it. It will be as night and day difference.

I had some eye strain when I first fired up the Air. After calibration, I am pleased with the colors and text read ability.

The stock configuration is bad out of the box.

My screen is calibrated but it's still there. I think the LG panel may just be bad with crosstalk.

What would help is if someone with a samsung display did these 4 cross talk tests and reported back.

My LG panel fails with #2 only. My other monitors pass all of the tests fine.
 
"These patterns are not comprehensive and should not be used blindy to rate one screen against another. The appearance of a visible cross-talk from any of these patterns does not indicate a "fault condition" with your display!"

I think by "does not indicate a fault condition" that page means the panel may be designed with that limitation as an accepted engineering tradeoff. This would be fine if all MBA panels were like this. The problem comes when there appears (not confirmed) to be an alternative that is better. And that one can only get it through a lottery of parts.
 
Stopped by a local reseller with 2011 MBA 13" Samsung-panel to try out http://i.imgur.com/zPilY.jpg. Result? No flicker, no matter how I viewed it.

I can go back for testing crosstalk1...4.html later. My LG-panel fails #1, #2 (badly), #3. Passes #4.
 
Sadly find that every lcd (desktop monitor, samsung mba, thinkpad t400s, even $300 dell mini 9 netbook) in hand has no problem displaying these crosstalk patterns, except the new lg mba.

I knew that there was something weird with these screens. They were hurting my eyes. I ended up returning the MBA yesterday and have now completely given up on MBA. Will go for the 15" MBP which will really serve my needs. Video card, Memory compromise along with really bad display.
Maybe a future generation of Air.

My €2000 Cintiq 21UX also fails with 2 also. So it's not just cheap displays :)


The samsung panel in my MBA does not.


Edit..

My iPad 2 flickers when viewing test 2 in Horizontal orientation, but not vertical.

OP, if you feel yourself struggling to read try entering this in terminal:


defaults -currentHost write -globalDomain AppleFontSmoothing -int 2

or this:

defaults -currentHost write -globalDomain AppleFontSmoothing -int 3


What's the default? 0?

Turn up your brightness. It fails the first 3 at full brightness - assuming you hope to see 0 flicker.

And probably it's better to link to the source for credit and wider understanding.

"A fortunate side-effect of inversion (see above) is that, for most display material, what little cross-talk there is is largely cancelled out. For most practical purposes, the level of crosstalk in modern LCDs is negligible."

Tested 2011 MBA 13" Samsung-panel (LTH133BT01A03) against crosstalk1..4 and all of them PASSED.

I'm torn. I have to ask for a refund and perhaps skip this generation of MBA's, as there's no friendly Apple Store (only retailers) to help out. I don't feel like playing parts lottery. Really, really disappointed.
 
Well, We will see what happens when my amazon order comes in.

It will be number 3 - I had samsung ssd in the first two.. samsung display then lg display...

I just know the penalty for being indecisive will be the unreturnable LG Toshiba combo.

However, it's also a bridge machine and under a grand.. so I'm fine with it.
 
So... this one has the Samsung screen and yes the Toshiba drive. At least the 50 / 50 rule worked this time. Yes, I can read finally on this screen and Yes there is a significant difference between the screens!!!!!! I want to say this again, yes there is a significant difference in the screens!!!!!! Apple you have something coming on this one, just give it a little, tiny bit more time.

Now on a side note, the Samsung isn't as bright and yes when the screen is pitched, viewing angles are a tiny bit noticeable. But the bottom line is the Samsung is the premium display. MOREOVER, you can read text on it at any brightness setting. For all of you out there that received an LG display, return it, replace it, demand a new one until apple gets it right, for you will never, ever be happy without it!!!

my LG screen is fine...
 
I have owned both in the last week. I had a Samsung on the 1199.00 model with i5 and it was fine. And now I have the LG panel on the 1649.00 model i7 with 256 SSD (replaced the other to get bigger HD - turned out I needed more space)

Anyway, I have been trying to see if there are any problems or issues with this screen like so many people on this forum seem to think. My conclusions after 5 days... I think it is beautiful. Both in the light of day within my office and in the dark of night while sitting on my couch surfing or writing.

I did do a basic calibration - (alt-F2, click color, click Calibrate) to make it the way I like it but that is all. I normally run with brightness at half or less. Again, I have been very happy with this screen and really don't see what all the fuss is about. As an aside, I even got the Toshiba SSD in this i7 model instead of the Samsung that I had in the previous i5 model. Again, I notice no actual-use speed differences. (Yes, there are benchmark differences, but they mean very little in real-world use.)

So those are my observations. LG screen seems to be great. If you are having issues, try a calibration first, then take it to a Genius at the Apple store if you can. Otherwise, do a Time Machine back first, then return it for another one.

Got the 13'' MBA 256G LG Monitor and failed on crosstalk2. Flickering is already noticeable starting even as low as 2 brightness level
 
No flickering on my 13" LG screen. But there is some backlight pulsing when set on high brightness.

This is a quote from that site "These patterns are not comprehensive and should not be used blindy to rate one screen against another. The appearance of a visible cross-talk from any of these patterns does not indicate a "fault condition" with your display!"
 
I have an LG display and it's working properly for me. Even on max brightness, I can read the text perfectly.
