MacBook Pro :: Horizontal Line Across The Screen?

Sep 27, 2009

I have a new MacBook Pro (A1286) 2.66Ghz which is just over two weeks old. Whilst watching a video on YouTube a horizontal line appeared across the screen. I tried rebooting, however, the line was still present. I have tried switching between the 9400/9600 and the line is still visible.

The line is still there when I boot the laptop into Windows, does it look like I have a faulty GPU/logicboard on my brand new MacBook?

Here's a photo of the problem.

OS X :: Dot Mark And Tiny Horizontal Line On Screen

Jul 6, 2010

I've just noticed two small marks in the lower right-hand corner of my iMac's screen: a tiny horizontal line to the right of a dot. I can see them when I restart the computer, but not when the wallpaper is on the screen. Clear Screen won't remove them, but they don't seem to be scratches either, partly because I can't feel them. Do you think they're dust specks or something like them tat somehow got behind the screen? I hope there's a safe way to remove them because I hate to see them.

Intel Mac :: Horizontal Gray Line Across Screen?

May 21, 2012

This evening, quite suddenly, a gray (or black, depending on what's on the screen) vertical line has appeared across my imac screen, about a quarter of the way up from the bottom.  Above that are some are three, much lighter lines (more like subtle variations or blocks of colour running across the screen). These appear on all windows I open.  I took a screen shot using grab and the very definite gray line doesn't appear.

OS X :: 10.6.1 Snow Leopard Hangs And Blue Horizontal Lines On Screen?

Nov 2, 2009

Over the past month I have encountered a number of bugs with Snow Leopard on my MacBook Pro (mid 2006). Ever once in a while, usually during high performance task (like watching flash or encoding with handbrake) the temperature of my cpu will spike to 85-90 degrees celsius and then the system freezes.

During this freeze, I can still move my mouse, but I am unable to click on anything on the dock or any program. Moving the mouse over the dock does not invoke the magnification either. I have to do a hard reset to fix the problem.

Also every once in a while, a long blue horizontal line will appear in on the screen. (sometimes their in iChat windows, sometimes safari, and sometimes the desktop as shown in the photo).

MacBook Pro :: Horizontal Line In Display?

Jun 21, 2010

i've got a little problem with my Mac Book Pro.

I have a white line in the display where I also have my dock. So it's not always on the same Display. You can see a few pictures attached that show you that this line is some kind of weird. Windows that are always in the front like "About my Mac" are over this line and if I open all windows of one program I get three of those lines.

The lines are here since I updated my MacBook to the newest firmware.

MacBook Pro :: Horizontal Line Appearing On Retina Display

Sep 5, 2014

i recently bought a 13"retina display macbook pro. It is so disappointing. There is a horizontal line that appears on the screen and disappears. This was for the third time i had to face the same issue. When i explain to the staff at the apple store they say that they have not come across such issue, for which i showed a proof from the other part of the world.

MacBook Air ::5 Dead Pixels In The Center And The Horizontal Line Options

Nov 20, 2008

Anyone think this is a good deal? http://www.amazon.com/Apple-MacBook-MB003LL-Laptop-Processor/dp/B0006HU4DK/ref=pd_bbs_sr_1?ie=UTF8&s=electronics&qid=1227225131&sr=8-1. I bought the Rev B, but had to return it because of 5 dead pixels in the center and the horizontal line issue. I am thinking of saving over $1,000 by getting the above. It is new/in box and from amazon. This is the best deal I have seen. It is even cheaper than the refurb models at apple.com.

Software :: Video Display Is All Blue With Horizontal Lines?

Jan 1, 2010

My iMac boots up (OSX 10.4) and when the desktop is about to appear the little spinning wheel start to get "fuzzy" (yes only the wheel), then when it's time for the desktop to appear the entire screen goes blue with horizontal lines across it. I can see nothing on the screen at all except that mess.

Weird thing is, if I boot using the install disc, everything is fine. he display never screws up. So I am guessing some file or something is corrupted in OSX?

I was going to do a restore, but since there have been some updates since I got it, I am worried about that whole process and not being able to get to my pictures and what not on the HD. The procedure where I can archive the current OS and reinstall the original seems like my next step.

MacBook :: Screen Goes Blue While Using / Diffrent Blue Colors Appear On Screen?

Sep 17, 2010

while i am using my macbook the screen will suddenly go blue and flash between different blue colors like it is trying to work. sometimes it comes back on but most of the time it stays like that. I have to force shut down with the button and then restart...about half the time it is still flashing blue after the restart and if it does work, it goes blue eventually.

dont know if its a problem with the screen or what because the computer continues to work...if there is a movie on, you can here it in the background and the screen just flashes.

MacBook Air :: IOS 7.1.2 / Horizontal Lines Across Screen

Aug 24, 2014

I've had my macbook air 13" 256GB for four days now, I had it shipped to me in Canada because I wanted the ram to be changed to 8GB. When I'm scrolling around on the internet I see a horizontal line appear in the lower half of my screen, it disappears quickly so I haven't been able to get a screen shot. I have apple care, should I take my laptop in? Is this normal? I've been very careful with my laptop, I haven't dropped it or anything (I even have it in the Tech21 Impact snap case).

MacBook Pro :: Unable To Know Horizontal Lines Across The Screen In MBP?

Oct 1, 2010

I have a MBP purchased in late 2006 so it's fairly old.

Lately I've been having really random lock ups and freezing maybe once every week or so. Sometimes when I hard reset it, there's a few horizontal lines across the screen, usually just on the background. It'll go away if I restart it again.

I used the onboard disk checker and no problems are detected. Is this a sign that the hardware will fail soon?

MacBook Air :: Horizontal Marks On Screen From Keyboard Recess

Nov 8, 2008

Just what I needed - another thing to obsess about! On my screen, corresponding to where the bottom line of the keyboard recess is, I have a horizontal marks on my screen. Does anyone else have this? I've tried buffing with some iKlear and a soft cloth but it won't go away. I can't see it when the screen's on but it's bugging me now, as these things tend to do. With my old Powerbook I kept the plastic sheet in between the sceen and keyboard but assumed this was not necessary with the recessed keyboards. Now it seems its the edge of the recess, rather than the keys themselves, which is the problem.

Have had this macbook for just over a week, purchased off original owner who bought in Feb this year with Applecare warranty. Upgraded ram immediately to a G.Skill 4Gb kit. 4 days ago, computer randomly froze with horizontal coloured bar. Called Apple next day, the guy there told me that sometimes this happens, and that I should only be worried if this occurs ago. 4 days later, we are at this present scenario: In the last hour or so, has crashed 3 times.

MacBook Pro :: Display Is Frequently Horizontal Gray Lines Going Across Screen

Jul 1, 2014

my MacBook pro display that there are frequently horizontal grey lines going across my screen. I've noticed it mostly when the display color should be grey or white, but that's not always the case. It occurs mostly in my Google search bar using Firefox, and also occurs heavily on Facebook in the comments/reply section of a post. Outside of the browser I've also seen it when looking through some personal photos, especially of the sky, the lines will seem to sort of outline different contrasts in white or light tones, kind of like the Magic Wand tool would do in Photoshop. The lines do flicker and change when scrolling.I attempted to snap a photo with my iPhone the best I could. 

My specs:

-13" Macbook Pro (2009)
-Intel Core 2 Duo 2.26 GHz
-NVIDIA GeForce 9400M
-Resolution: 1280x800, 32-bit Color
