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.
It's not a bug, it's a special effect. Suck it up, fanboys!
Apple users are to fuzzy usually.
It does matter if the desktop is stable and not grey lines on the the display. If you use your laptop on a plane, in the train, on a conference, on a toilet or in a cafe, the light conditins are very badly and therefore you don't see the grey lines.
Apple is using low quality displays! [/sarcasm]
No seriously in all laptop reviews I have read so far the testers complained about the displays. So not really suprising news

Cool transparency effect, without any CPU cycles involved! I am not a Mac user, but this brilliant trick makes me want to... uh...

'Cause apple is pants.
Anyway, it sounds like a clear case of bad hardware, and thus should be replaced. Obviously still in the warranty period, 'cause the items are barely a few months old.
Though, actually, the article talks about updating firmware. Odd.
Actually, the entire article doesn't say much at all.
I wank in the shower.
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.

a feature?
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.
I had the same kind of grey lined textured look on a thinkpad and came up with a test image that made the issue more obvious. I was never able to get satisfaction.
Look at the bottom of this page:

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!
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.
is it me or is this website a joke website, like the onion?
from the looks of the image, it looks like one of the STANDARD MAC OSX desktop images.
when i read the topic, i was thinking horizontal banding that occurs on some older LCD's when you move them and the chassis flexes a little bit.
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!
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"
Okay, I've looked at the picture, and I can't see any grey lines. Well, technically I can see lots of grey lines, they make up the background of the menu bar at the top of the screen. And I also see a bunch of grey lines making up the "swoosh" which looks to me like part of the desktop wallpaper. Anyone got a better picture?

You PC-using commoners just don't understand good design ascetics. We hipsters who are better than you understand that the gray lines are a design choice, not a flaw.
SJW: Someone who has run out of real oppression, and has to fake it.
I am wondering if we are giving Apple a double standard here. I think right now the MacBook Air is the only Ultra lightweight and Thin laptop that performs as well as a Mid to upper mid level PC. These lines while an issue, the question is do other laptops that use these displays have the same problem.
If something is so important that you feel the need to post it on the internet... It probably isn't that important.
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.

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):
http://www.hp.com/hpinfo/newsroom/press/2008/080811xa.html?jumpid=reg_R1002_USEN
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...
(disclosure: I work for EDS an HP company, as a consultant)
----- "Profanity is the one language that all programmers understand."
New product lines from Apple almost always seem to have teething problems, this has been especially true with the laptops. I always recommend waiting till the first revision of the products appear and let others take care of the "beta" testing, of course my recommendations aren't usually followed by those who just need to get whatever new bling Apple has put out...

[...] 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.
First their was the moobooks, the bad batteries, random shutdowns, warping plastic, the DRM, the lack of replaceable batteries, the restrictiive app store, steve jobs health scares etc.
Despite their "switch" and "I'm a mac" adverts, apple still have less than 5% market share, even with switching to intel and having windows compatiblity
Face it, the 2009 mac world will be a disaster. All it will be is a crappy beta of "snow" leopard, intel atom based mac minis, I7 mac pros and imacs, all with built in DRM.
Fuck Apple, and fuck mac zealots along with linux zealots and all "open sores" zealots too.
What Apple appears to be doing about it
You're wrong as well. Step 3 shouldn't even be mentioned:
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 4: Profit!
The picture in the article is of Tiger (Mac OS X 10.4) OS.
Not one Macbook Air has ever shipped with Tiger, as it was introduced after the introduction of leopard.
Step 3 (which really should be step 1) is 'Be Apple', there really are no unknowns in this equasion.
I think right now the MacBook Air is the only Ultra lightweight and Thin laptop that performs as well as a Mid to upper mid level PC.
The MacBook Air is specced similarly to the Macbook at the time of its introduction, or the contemporary Mac mini, with a mediocre processor and a significantly below-par GPU. It's nowhere near a "mid to upper mid level PC", it's smack dab in the center of "entry level".
When the MacBook Pros were released these values were wrong. The fans would not kick in early enough and the machine would become unstable. Tweaking them a bit made the machine a bit louder and shortened the battery life slightly, but stopped it crashing (the CPU was fine, but the memory chips got too hot). A subsequent update fixed the problem and I don't have the fan control or temperature monitor utilities installed anymore.
You must have a more recent Macbook Pro than me. I have to remove the battery to keep it from overheating with more than about 50% total CPU use (100% of one core or 50% of both cores) even with fan control utilities.
See this temperature graph.
They were sued about this, so rather than change to 8-bit panels, they simply tell you that it can display "thousands" of colors now rather than "millions" as they did before.
The picture in the article did not come from a machine affected by the problem the article describes.
First off, those aren't horizontal lines in the display.
Second, that picture is from a machine running OSX 10.4 (Tiger). You can tell because the apple in the upper left is blue. In Leopard (10.5), it's black.
The Macbook Air is ONLY available with Leopard. The older version of the OS doesn't have the drivers for the Air's hardware and will not install.
Therefor, the pic may be showing some sort of video distortion, but not what's being described in the article.

Why, hello Clue!
I guess the Macbook Air is easy to return in that Manila Envelope, right?
Once I was a four stone apology. Now I am two separate gorillas.
Isn't that touted as a privacy feature? You want wide angle viewing in your HDTV, but at the airport you don't want the guy sitting next to you to see everything on your screen.
Give a man a fish and you have fed him for today. Teach a man to fish, and he'll say "WHERE'S MY FISH, YOU IDIOT?"
Apple has responded to this issue by announcing new lines of Macbook Air with pink, aqua, and green lines in addition to the classic grey.
I've had exactly the same experience as the GP, going from an old PowerBook with a stunning (if a bit dim) screen to a MacBook Pro with a bright but hard-to-align screen.
From off angle, you can still make out text just fine, but you literally have about one to two degrees in which to hold your head where the panel shows the backlight evenly. Just slightly off to the top or bottom and that white page turns into a big, blue gradient.
No security advantage, all annoyance.
Your mind is clear / The things that you fear / Will fade with how much you / Believe what you hear
I made the same transition from Powerbook to MacBook Pro. I quickly sold the Powerbook so I haven't had the reversion comparison, but I can believe it. I find there's barely enough viewing angle to get both eyes to see the same colors. Trying to show stuff to somebody over my shoulder is a disappointment.
Even worse is the glare-enhancing screens on the new MacBooks. My sister just got one as a new Mac convert and she was stunned at how much more pleasant my old matte screen is.
For as long as Apple insists on the hardware + software model, they can expect to be taken to task for each and every hardware quality issue that pops up.
But how many issues will it take until they consider a different approach?
And what's up with Apple saying a firmware update will provide the fix? Is this a firmware issue?
Please advise.

That's not a bug, it's the new pinstripe feature.
Nothing to see here, move along.

My working theory on this is that, yet again, Apple stuck some like an 18-bit display on there and relied on dithering to pretend it's 24-bit (for Mac users 16-bit is "thousands of colors", 24-bit "millions")... they've done that on a lot of models. But it appears the display is not using an intelligent dithering algorithm (which avoids banding and the like.)
One good reason not to buy a Mac -- if I'm paying some premium price, I don't want a cut-rate display.
I don't know what I'm looking for and nothing is particularly obvious. Is it the line behind the menu bar?
Sometimes when I look at my MBP screen really hard I start to imagine I can see every little crystal suddenly freeze up and nucleate :O
...welcome our new "Grey Lines" overlords.
Others have noted that everyone is using poor quality displays, not just Apple, but I haven't seen anyone that mentioned that other laptops DO have the issue on display here.
I bought a Lenovo T61 in March and it had this same line problem. I went online and found others with the same issue (among other problems with the screen - it is just poor quality in general.)
I managed to get the screen replaced with one from a different manufacturer. A representative from Lenovo was participating in the discussion on notebookforums.com, where people were reporting issues with Lenovo laptop screens, and I sent my system in so that he could look at it himself. He acknowledged that it was bad and managed to get the repair guys to put in a different screen, but I don't think they're really doing anything to address the problem, like trying to get screen manufacturers to come up with better screens. Most people just don't care, unfortunately, especially with Thinkpads, which are aimed towards business not graphics.
So the result is that I have a different screen, from a different manufacturer (I believe it's currently an LG, while the original was from Samsung.) It has slight better viewing angles, but most importantly, the gray lines are gone.
Why are the lines such an issue? They really screw up photos and graphics. For the Macbook Pro, used by many photo and graphics "pros", that's a real serious issue. It's hard to capture how bad it really is, but here are some photos I took illustrating the issue:
http://mail.rochester.edu/~chacker/t61lcd.jpg
http://mail.rochester.edu/~chacker/t61lcd2.jpg
(I should note that the two screens shown are different sizes, but have the same resolution of 1680x1050, which is why the pixel size is different.)
For normal use, browsing Slashdot and writing TPS reports, or whatever, it is noticeable but you get used to it and it's not a problem. If you're doing photo editing, or even just looking at photos online, it is a HUGE annoyance. I was going to return the computer if I couldn't get it fixed because it was such a problem. Bad viewing angles and low brightness I can deal with, but these lines I really couldn't. The screens used in Thinkpads are supposedly 8-bit, so I don't think this is a dithering issue as speculated in other comments (I could be wrong and I'm not sure how that works specifically, that's just my feeling.)
So, avoid refurb, or any nVidia GPU? Hello integrated graphics!
