Well, most of you have read about lines and flickering, these issues appear on 9C9A screen by Chi Mei. One poster claimed to have another screen in another forum, I wonder if there is anyone else and if there might be a silent shift to better screens? So if you got another screen, post here.

Please do not post here, if you want to let us know that you have 9C9A and it's flawless. I know there are happy people out there.

Not trying to be cool, just trying to get this dude to understand there's another panel out there. No lines here as far as I can see. And no, I'm not taking a pic of anything. Rest assured, I don't drop $1800 on a machine and then proceed to talk myself into it being perfect. :)


Here's my panel info (finally found that ***** terminal command I was looking for):
Model: 00009C90
AU Optronics
B133EW03 V2

So... my 9C9A is AU Optronics, not ChiMei. V0 vs V2?

Regarding the #B133EW03: There appears to be the same panel, in v.1, v.2, and v.3; iFixit's teardown shows a v.1, adding to the 9c9a v.0 and jessica's 9c90 v.2

Lenox I believe was the one touting the idea that my panel as well as the 9C9A were ChiMei. To be honest, I had presumed mine was an AU based on the fact that the MacBooks with AU panels were actually better, not as great as my MB Air AU panel, but better all the same. That said, it would seem to me that thus far the MB Air Rev B HDD models all have AU panels, superior panels to the MacBooks as well as coming in 1st and 2nd versions.

AU panels, at least my panel, was under $300 to buy on a couple of sites when googled. So yeah, they're "cheap" and if something were to happen I'd probably just replace myself if AppleCare didn't cover it. :)

Now I bought mine on Monday last the second someone said theirs was on a truck. I would presume that Apple took whatever they had to take and ship it out to those who ordered online clearing out their backlog. Some may have gone to the stores, but I would imagine the online orders were basically filled first. Does that mean those who ordered online have the AU v1 panel and I just so happened to get a v2? I'd be interested in knowing if anyone has bought theirs in-store in the last 5 days and what panel they have.

In order to check your panel open terminal and past this command:
ioreg -lw0 | grep IODisplayEDID | sed "/[^<]*</s///" | xxd -p -r | strings -6


AUO is cheaaaaaaaaaaaaap.

Jess, you are so lucky and yes you are COOL :D I am glad that I did not give you my MBA cuz you would be cursed then :rolleyes:

Honestly, I wouldn't have felt cursed but I am glad that I just went to the shop and got it. I don't know what problems you're having, but I'm very happy with mine.

Yes, mea culpa, but I did get it from another forum where somebody performed the same check as you did. Obviously that was just wrong. Anyway, I am glad that at least there are diffrent panels out there. I will check my brandnew MBA that is waiting to be picked up for a refund on Monday. This one is a week 48 - so now the question is: Did the change the panel for the entire line or was Jessica just an exception. Panel IDs, please, guys!

That's weird. The screen type is just the same as the one above thats marked as 9C9A. I always thought a diffrent screen identifier represents a diffrent model...

And in another thread (http://forums.macrumors.com/showthread.php?t=615988&highlight=9C9A) you claimed to have a "9C9A" screen, so you still get the same result as Jessica with a "9C90"? Is the identifier worthless then?

No, he was actually right. In another thread you said you have a "9C9A", here you said yours is the same as Jessica's. Well this is kind of interesting since it matters what panel type is the non-defective one IF its a screen issue what I strongly believe.

I know but look above I wrote MY son's on the title line, I bought both the same day from the Apple Store, I really am puzzled now?

Every one needed to use the terminal , as My son's and mine are the same using that??

Now I am confused?

Now I'm just confused.

Who has the v1 panel? I think we can all agree all of them are AU Optronics (which explains the superior screen to the MB), but which Model identifier found in colorsync is the v1 panel?

Here's what I think I've found thus far:

9C9A = AU Optronics B133EW03 V0
9C89 = AU Optronics B133EW03 V0
9C90 = AU Optronics B133EW03 V2


iFixit claims to have a v1 panel, but is it the 9C9A, 9C89, or 9C90?
And FTR, Ironic, in all his infinate "buy a MB Air" fandom, has remained consistent in his statements that both he and his son both have rev B MB Airs with SSDs. So it is easy to get his statements mixed up if you gloss over the indication that he is speaking about his son's machine or his own.

Yes , I fixed that, so even now we both have the same panel as you Jessica, according to the terminal.

Both are the same all but the screenshots I posted.

Well, I certainly wasn't attempting to contribute to the line theorem. I do not think the panel itself is causing lines. I believe there's some interference somewhere. That's all. I thought we were just trying to see what panels the new Airs were using ... it seemed like the geeky thing to do.

Also, I'm under the impression the lines; their visibility, is purely subjective in some instances. We have a lot of claims and few photos. For those who have ponied up proof I still stand on my interference notion.

Trust me, I do review notebooks for a large journal over here in Europe: there are lines. I havent seen them on any other laptop yet although there are reports. But I did review a rev.A as well and it was crystal clear (but hot as lava). The fact that cameras might not catch the defect properly is not evidence against the problem. And it's a hardware problem, its the coating because the lines are not pixel related and thats what they would be f it was an electrical interference problem or a driver issue. In fact its most likely a problem with optical interference due to the display surface.

And yes this thread was indeed meant to check if the other display models might not have the issue.

It's probably either the coating on the protective layer or some interference but I'm guessing that the horizontal lines aren't from the underlying LCD panel itself. I put my face as close as I could to the screen and the LCD pixel layer itself looks perfect. It's just that layer above the pixels that has the weird problem.

If you read these threads it's widespread throughout North America also. I'm on my 3rd one with no correlation to 4 finger swipes.
