Grey Lines Mar MacBook Air Displays
adamengst writes "Numerous users have been complaining about grey lines that muddy the crispness of the displays of the recently updated MacBook Air. Doug McLean explains the problem in TidBITS, along with what Apple appears to be doing about it."
What, is this an audiophile forum now? I can only assume the lines fluff up the felty softness too.

LCD panel quality in general has been on the slide for a couple years now. Pretty much every LCD sold today has a trashy TN panel (6-bit colour and awful viewing angles), instead of mostly just the cheap ones like a couple years ago.
Game! - Where the stick is mightier than the sword!
I for one, think that a few grey lines make a display look distinguished.

Clicked pie.
I've had an intermittent graphics card problem with an '06 MacBookPro for a while now... it leads to occasional system freeze, maybe once a day, sometimes recently a lot more. One warning that a freeze may be imminent is the appearance of thin horizontal light blue lines during what appear to be block-copys of graphics (like scrolling a browser page) - freezes often come during intense operations like a Genie style minimize, but even turning all these off, the freezes still come. There are scattered reports of similar problems, mostly when new, and my experience tracks with these (more frequent when external monitor is connected, etc.)
Bottom line - I didn't pay the 15% AppleCare tax, so I'm SOL in terms of support from Apple, they haven't admitted to anything systemic, though it obviously is at least somewhat reproduceable. What I'd really like them to do is publish a kind of tech bulletin telling how to correct the problem if you have it, but I suppose that might take business away from their Genius bars (nearest one being 2 hours drive from here.)
If they wanted a reputation as a truly awesome company, they would develop and release that kind of info instead of suppressing it to affect the (false, and repugnant) air of perfection.
DonÂt get me wrong die macbook air has so many things done right, but I get the feeling that it was released prematurely. I am not sure how it is with the current ones.
But I have one of the first generation, and you cannot run more than 10 minutes on 60% processor load after then the speed drops significantly due to excessive heat.
Which means since I mostly use ot for development I reach this stage after a few hours of work.
I called apple about this, and the support seemed to be rather dumb regarding this issue! Searching on the net revealed that others have the same problem. I assume this is a broken by design issue, since the heathing itself might be a problem in this formfactor.
Well maybe this problem is resolved with the current generation but seeing that they now have another problem with the otherwise excellent display.
Well to sum it up, if they aluminium macbooks would have been out back then I would have opted for a macbook instead of the air, but for now I live witht it and a handful of hacks installed to make the heating/venting issues more bearable!
"x is pants" is a British phrase meaning "x is rubbish".

The picture posted of the problem looks like the dithering's gone wrong and it's just showing lines rather then the usual checkerboard pattern
In my statistical study of one sample unit (mine), I've had my eye on the display since April, and I have no complaints with it.
However, I do notice that it takes longer to find wireless networks than my old PowerBook used to. Not sure why this is.
I've learned that they're worthless, so I don't read AC comments anymore.
My Mac SE from 1988 had all grey lines! You kids and your 'color' monitors...
...considering I now use LCD wherever a visual display unit is required, I'm very fussy about the flaws I allow. I sent some Samsung panels back and had them replaced because two of them had ghost patches. One had a bug (a real bug!) sandwiched in between the LCD layer and the backplane. Yet another had a partially detached backplane (which resulted in uneven lighting). No good to me at all. I can deal with one or two hot or dead pixels, unless it's on a panel I use to do serious work on (read: graphics-intensive stuff) where the panel has to be pixel perfect and the backlight has to be even and of the right colour temperature. As for Apple's not very new problems: yes, their panel quality has suffered a huge amount over the years. I have a G3 Lombard with a perfect panel (no hot/dead pixels and the light is even), and a G4 iBook with a panel which has dark corners and four hot pixels right in the middle of the panel. Not hugely offputting unless I try and watch a DVD... and now the Airs have panel problems? Hardly surprising... tho don't try and pick one up by the top edge of the screen, I heard of a guy who couldn't wait to get home from the Apple dealer over here and took his MBA out of the box as he left the shop... snapped the notebook in half. ...sort of put me off from buying one...
Operation Guillotine is in effect.
Wow, you totally got this one wrong. You missed the very vital step (see below)
Step 1: Make expensive laptops with a shitty display.
Step 2: Start another ad with an undergrad making fun of his computer science professor.
Step 3: ????
Step 4: Profit!
Note this only makes sense in English. In American, the phrase means 'x is trousers,' which is quite nonsensical.
I am TheRaven on Soylent News
The article is in German and not freely available online, so I'll summarize it: The problem is in the display electronics. To prevent the liquid crystals from polarizing themselves (sort of a burn in effect), the polarity of the voltage is reversed after each frame. If the center voltage is not exactly between the low and high voltage, then the pixel is brighter or darker, depending on the current polarity of the control voltage. The display drives the lines with alternating polarity, so this deviation causes an alternating pattern of slightly darker and slightly lighter lines.
submitted by somebody at a blog, a vague summary about a 'story' at... that same blog!
Maybe it's not a blog - sure reads like one.
"Numerous users have been complaining about grey lines that muddy the crispness of the displays of the recently updated MacBook Air."
That line in the summary -is- the 'story'.
"Doug McLean explains the problem in [the advertised blog]"
No he doesn't. He just recaps what the supposed problem would be in some detail with an example image. Kudos for the image, but there's no explanation of the problem - what causes it, why it's only apparently in late 2008 models, etc. etc. you know.. explanation - whatsoever. There's wild guessing as to what's causing it...
"Theories about the lines are scant, but the main ones attribute them to the new anti-glare coating or the new Nvidia graphic chips. Many users seem suspicious, though hopeful, that a firmware update will resolve the problem."
But that alone should make you quirk an eyebrow... I do hope those 'many users' are on the side of 'the new Nvidia graphic chips [are the cause]", as I've got no hope whatsoever for those who think that a firmware update would fix an anti-glare coating.
"along with what Apple appears to be doing about it."
Well I guess including that information in the summary would mean even less people would click on the 'story', but the answer is "we don't know". As usual, with Apple, I know, but from the 'story'...
1. "Apple has issued no official statement on the matter"
2. "we hope Apple [...] takes [...] steps to resolve it"
i.e. "we don't know what Apple appears to be doing about it"
And "x is rubbish" is a British phrase meaning "x sucks".
obviously no deficiencies vs. no obvious deficiencies
If you click on the pic, a larger version comes up and you can see the lines on that one.

Nope, it's not English versus American. You're thinking of British versus American. In the English dialect, the correct phrase would be "jolly bad show, old chap" or the alternate form "cor blimey, guv'nor, one is not amused".
All FanBoys also know that you must love on your machine. Unlike PC varieties that don't need to burn in a laptop display like a transmission on a new car (from 20 years ago), you need to love your machine.
-Stroke the keys lightly as if to say, I love and want everyone to see me holding your hand as I walk down the street.
-Offer the CD/DVD to the machine with both hands. Don't force it in, be very gentle the first time. It needs to loosen up a little before you start inserting them more aggressively.
-Speak lovinging. With your enthusiasm of buying an overpriced, sexy trophy computer, you might be tempted to do a cool dance and yell and scream. This can produce flying spit that may land on the keyboard and render it soft and cushy feel.
-Carry with a keyboard pad. Never close the lid without putting a soft pad over the keyboard. The display and keys with chafe. Don't use powder to reduce chafing.

Actually, you have that precisely backwards.
in American English: Pants = Trousers or Slacks
in British English: Pants = Underpants. It's also where the word "panties" (aka: women's underwear) comes from.
So in America, "Underpants" became "Underwear". In Britain, "Underpants" became "pants"
In Soviet Russia.... well, I have no idea what they call their underclothes, but I'm sure it has something to do with the underclothes wearing YOU. Or something like that.

HP came out with a new LCD display and (also in notebook form) that displays billions of colors.
This beats even apples cinelerra displays:

HP press release (on the notebook):

Many people don't know about it yet but it appears to be making waves..
Possibly apple is getting to comfortable with it's new marketshare.
Personally I will be looking at the displays as an alternative, when I buy yet a bigger monitor...

[...] and result in a disappointing display, particularly for a premium laptop.
Since when is the MacBook Air a premium laptop? It sure has a premium price. And it looks stylish. But that's it. ;) (Apple fans, stay with me! :)
You know what else is like that? An expensive whore "girlfriend".
I think Apple has done some cool things. But this (or the iPhone) is not one of them.
The 18 bit display was the first hint.
It's more a EEE PC concurrent. Which means that it's useless for real full use, because of its slowness and lack of features (one example being Firewire).
This is fully ok, if the laptop is really cheap. Unfortunately, that's where the MacBook Air fails. It's not cheap. It's really expensive (compared to the real market. Not to other overprices Apple products.)
I really wonder, how cool Apple's products would be, if they had concurrency in their own domain. If for example MacOS XI would have a HAL that would allow other companys to do the same with their systems. They would have to look good and have more features to have a chance, so Apple would have to add even more, thereby lowering the price to a realistic market level.
Any sufficiently advanced intelligence is indistinguishable from stupidity.
In Soviet Russia.... well, I have no idea what they call their underclothes, but I'm sure it has something to do with the underclothes wearing YOU. Or something like that.
This is "trusiki" or "trusary" for you. And sometimes they do end up wearing you.

After WWII, Russia ended up with tons of German clothes as part of the spoils of war. Not being familiar with the styles of clothing worn in Germany, many women were seen using German undergarments as evening gowns. (e.g. going to the Opera, a ball, or a fancy party) For the most part no one noticed the difference, but those that were more familiar with German life were amused to no end.

It means, "I'm the typical slashdot hack who isn't nearly as clever as I think, so I'll just post some stupid meme to sound intelligent".
I agree. My MacBook Pro has a really crappy display for such an expensive laptop IMO. From whichever angle I look at it, I never see the whole screen in the same brightness.

The desktop cannot be displayed without grey lines because Steve thinks grey lines are cool. Could you please try not to think too different?

This is not entirely true. For example, Apple's cinema displays are 8-bit panels.
It's also not just an Apple thing; if you buy a computer from absolutely anyone, and don't go out of your way to make sure you're getting an expensive monitor, you'll end up with a 6-bit panel. Most people don't care. Gamers even prefer 6-bit panels, because they have better black levels and faster response times.
