Who else has faint horizontal lines in their 17" Display? Look closely!

Description: Every other horizontal pixel row appears brighter than the alternate, creating a scan-line style effect that also contributes to the washing out of the display. In seemingly random "luck of the draw" machines, lines can either be highly visible or not be present at all.
In displays where it is faint, you may not notice, but once you become aware of it is a real problem if you work closely with your computer, and graphics.
This appears to be the same issue that has been widely reported in the past with Macbook Air computers.
The three computers that I have had this issue with:
1 - Glossy, 9C99, lines visible even from three feet away.
2 - Glossy, 9C99, lines about half the visibility
3 - Matte, 9CAC, lines again about half the visibility of #1
I have also had 3 glossies and 1 matte that have not had these lines at all. 3 Unibody 15" MBPs have also not had any such lines. I have also been unable to detect these lines on any non-Apple computers I have observed, nor any of Apple's other models or displays.
I put a 17" Matte without the lines next to one with the lines and attempting to take photos, but could not get them to turn out at all for a variety of annoying reasons (unclear image, moire effects, etc). I was however able to take extremely close macro shots and there is a difference visible in the pixel arrangements, apparently.
Who else has this one their display?
Thanks
Both pictures taken in upper-right corner of screen with standard Leopard desktop picture.
First image is display with no visible lines, second is display with visible lines.

It exists regardless of graphics chip selection or resolution. The machines either seem to have it or they don't. It seems to be something in how they are made. What I see in the close-up photos seems to suggest a variation in the layout of the pixel diodes in the display. I really want to know how many others have this in their display. Maybe there was a small bad run of them over a few months or maybe they are a multitude with this issue.

  • Iphone 4S display has faint diagonal lines.

    Is anyone else experiencing faint diagonal lines on their iPhone 4S screen? They are most noticeable on bright, solid colors. they are very faint but visible enough to detract from the display quality. Does anyone wlse have this problem? Should I make a warranty claim?

    Yeah I have that probablem to but it only happens when I'm not looking straight at the screen. I think it's the same with all iPhones (at least retina ones) cause I got a iPhone 4

  • Faint horizontal lines accross iMac lcd

    Had a 24" iMac that developed faint horizontal lines across the lcd that got progressively darker the longer the computer was on. Had the lcd replaced by Apple twice, but after a couple of weeks the problem returned. They gave me a new iMac, but a month in I have the same problem with the new machine. Has anyone encountered this problem? Is it an inherent issue with iMac lcds or is it something external affecting my machine? And I'm not talking poltergeist. Help, want this fixed.

    We have a 20" imac Core Duo that was purchased summer 2006 - then about 5 or 6 months ago, it started developing horizontal lines across applications (Safari, Mail, etc) and the desktop - sometimes they would go away, sometimes not... I thought is was some video driver conflicting, upgraded to snow leopard, went to the genius bar, etc... but lately it got worse to the point that it started locking up every day... this after going weeks or months without a reboot and over 3 years having almost zero crashes...
    I read in a forum where the video chip (GPU - graphics processing unit) was heat sensitive and thought that after 3+ years, maybe it was dusty in there... I installed the iStat widget to monitor the temp of the GPU and installed a fan control (software) where you can increase the minimum speed of the hard drive fan (allegedly located above the GPU). I also put the end of the vacuum on the fan vent just above where the power cord goes into the back of the monitor and let it run for a while hoping to clean things out...
    5 days later - zero display issues, zero hangs and zero crashes - and the GPU runs an average of 25 degrees cooler than before. This after a genius bar guy told me that it probably needs a new display board. Good Luck!

  • Why do I get faint horizontal lines when I print from elements 12 mac

    why do I get faint horizontal lines when I print from elements 12 mac

    Hi Ben,
    I can't reproduce that behavior.  The only two things I can think of at the moment are (1) you accidentally added a shortcut as a panel shortcut instead of a diagram shortcut or (2) the name of the object you specified isn't for the "Multiply" node, but for some other node (you said "Multiplication" in your initial post) that can only be dropped in certain places (i.e. maybe it's a node that is only valid in Simulation diagrams).  Can you post the following lines from your LabVIEW INI file so I can look into it further:
    QuickDropDiagramShortcuts
    QuickDropPanelShortcuts
    Let me know,
    -D
    Edit:  Yeah, what he said.

  • Horizontal lines on new PowerBook display

    Here is my experience with the new PowerBook display/horizontal lines issue. Please post any constructive advice you have that I can try - either to eliminate the problem or to pinpoint the cause more accurately.
    I used to own a 15" Powerbook from about 12 months ago, a 1.33GHz model. The display on this was fine. Much better, in terms of brightness and clarity, than my other HP & Dell Windows laptops. When the PowerBook was stolen, one of the main reasons for immediately buying a new replacement PowerBook was the superior display quality.
    At the start of November the replacement PowerBook arrived - a 15" hi-res 1.67GHz model. The faint grey horizontal lines covering the whole display were immediately visible. The display is substandard compared to both the previous PowerBook model and my Dell laptop.
    Apple Care telephone helpline suggested an NVRAM reset and a PMU reset. Neither of these made any difference.
    The PowerBook was then sent back for replacement and a week or so later the new replacement arrived. This also had exactly the same problems.
    Apple Care helpline this time said that they could not find any problems with the PowerBook and I should first try the PowerBook connected to an external monitor and secondly take it to an Apple Dealer to show the problem.
    I tried it on an external monitor, but unfortunately this is only an old Nokia 15" CRT monitor and though the lines appeared to not be there, the quality of the monitor makes the result inconclusive.
    Next up, I will take the PowerBook to the Apple Store. At the same time I have copied "Aqua Blue.bmp" onto my Dell laptop. With the two laptops side by side showing the same image, the defect in the PowerBook display is clearly visible. I hope to be able to take both machines to the Apple Store later this week. I will let the forum know the results...
    So, are there any other tips/advice from users as to other tests I can run or other methods to improve the issue?
    Many thanks!
    It seems obvious, but please don't contravene the Terms of Use for this forum. If you want to complain to Apple, please do it elsewhere - locked posts will get us nowhere

    n2o2,
    I don't know what let you think that you will eventually receive an AluBook without stripe : Apple Care let you think that ???????.
    I have been reading the stripes topics each day since I ordered my new powerbook, late october. I did not see one single post proving that a "free line" 15" powerbook does exist.
    The real evidence would come from someone describing the difference between a "non affected" new powerbook sitting besides an affected one, coming from the same PB generation and with exactely the same LCD profile and screen / Colorsync settings.
    I did not see a single story like that among the hundred(s) of posts related to horizontal lines.
    I have read one post stating that the screen is "crystal clear" and "sharp". The one I received today could be described like that, but it displays those lines, except from the 8 or 10 upper rows of pixels on the menu bar.
    The pb15_problems.png file is a very interesting one to me, as it demonstrates that the lines could clearly be attenuated using a single filter without compromising the sharpness/Brightness of the image.
    If I compare side by side my 3months old previous generation powerbook and the new one, I must say that (except for the stripes) there is not much difference in daylight in terms of brightness but a perceptible better brightness in the complete darkness.
    Well, if someone could prove that some of the new powerbook do not display this "feature", this would certainly push me to return mine. But, seeing how it is difficult to get this organized, I may not want an exchange but a refund, or an upgrade for a 17".
    Please tell us quick if you win this battle.

  • My Mac Book Pro has faint horizontal yellow lines moving vertically. on the monitor.

    My early 2011 MBP 15" has developed a phenomenon of faint, horizontal yellow lines, in clusters, flickering and seeming to move vertically.  It is intermittent and cycles on and off with about 10-15 sec. on and 10-15 sec. off.  It is faint enough that it is very hard to see except on a white screen, or a large white area.  I first noticed it about a month or 6 weeks ago and it seems to be getting a little bit more noticeable. It is still faint enought, however, that I really don't notice it when I'm working.  But it's not hard to observe if I stop and look at a white area for a little bit.   I am not noticing any other abnormal behavior.
    I have been very busy and kind of ignoring this problem.  But a couple of days ago, I realized that I have only 15 days left on my 3 year Apple Care on this machine.  At the present level, it SEEMS harmless enough, but I realize it could be a failing video card or video power supply, I suppose (it kind of has a flicker rate suggestive of 120 Hz AC).
    I'm probably going to make a Genius Bar appt. in the next couple of days, but I just thought I would see what comments or suggestions this collectively very wise community might have.  I am vaguely aware of comments about "hardware diagnostics" built into the Mac, but, if true, I don't know the details. Comments solicited!

    So I went to the Genius Bar with the history as outlined above.  We had to watch my display for almost 10 minutes (while he checked various system stuff) before it would perform.  But then it cut loose with a very convincing display of the faint, fuzzy groups of yellow lines moving slowly up the screen. 
    Tech pointed out that we were booted to an OS running on the store's server, NOT mine, so this ruled out software problems in one stroke.  He said he'd never seen anything quite like it but felt it was EITHER: video "card" section of the main logic board (all on one in a MBP) OR a failing display.  He said one or both would be replaced. 
    Two days later, picked up my MBP: problem solved!  Tech said they connected my laptop to an external display (which I had not tried because I didn't have one available.....though maybe a tv could have subsituted, now that I think of it!) and NO PROBLEM driving the external lcd display.  So they replaced my 15" lcd display and problem is gone.  "Bill" was about $600, parts and labor, but Apple Care picked it up (with 6 days left to run on the coverage!).
    So that's the follow-on for this problem, fyi.

  • How to see who else has iMessage?

    Ok, so if I go to message, and then go into my contact list, how do I actually find out who else in that list has iMessage?  From the look of things, I can only find out once I click on their name to send them a message.  Surely it makes sense to be able to see within the contact list who else actually has it, or I don't know who I can send one to.
    Or am I missing something?

    I found that it automatically switches from text to imessage if the contact has that upgrade

  • PDF's printing with multiple faint horizontal lines

    When printing documents to PDF (using the standard PDF printer), and then printing the resulting pdf to hard copy, I am getting faint, thin horizontal lines, appearing in groupings of 3-6, occurring at regular intervals down the page. These are not visible on the pdf, but only appear on the hard copy. Most peculiar...any suggestions gratefully accepted !

    Sounds like you are looking at a graphic, not text.

  • HT4061 My ipad has coloured horizontal lines

    My Ipad has got coloured lines running accross the middle of the screen.  Is there anything I can do to get rid of them

    First thing to try is a reboot of your iPad. Press and hold the Home and Sleep buttons simultaneously ignoring the red slider until the Apple logo appears. Let go of the buttons and let the iPad restart. See if that fixes your problem.
    If that doesn't help take your iPad to an Apple Store for a consultation. Make an appointment first.
