I'm getting this horizontal bar that changes colors and sometimes the whole screen image looks like it is vibrating rapidly up and down, I'm utterly at a loss. The model in question is an Early '09 with the 9400M IGP. It just randomly started last night. I've already had a video issue that got fixed, I think it was the GPU
View 3 RepliesI have a Macbook Pro 2.2 Santa Rosa Rev. D model. Recently I have discovered gray dots appearing along the top of my screen.
A few at first, but masses growing are growing rapidly. In the past 3 weeks the problem has started to spread to both my right and left edges as well. Under different viewing angles the dots sort of dissapear. The dots are not uniform in size or pattern.
I have a slight feeling that this has to do with my NVIDIA 8600GT graphic card.
I read tonight that that specific card was reported faulty and thousands have had problems and have had to get their logic boards replaced.
I also read that Apple extended their warranty for this specific reason.
Anyways, the dots are increasing and it's worrying me as I am not sure if this will be covered or not.
Mac-mini, OS X Leopard: Suddenly my wife's Leopard Mac- Mini (monitor) screen shows a 'vibrating' display that is split into three distorted parts. I can see it is the Finder shown three times. Fixing Permissions does nothing. Is this a hardware or software problem?
View 5 Replies View RelatedMy tibook .867Ghz was working fine this morning, but now when I restarted it this afternoon, the colors are all off (lots of green and rapidly vibrating pixels in background). The computer works, I can run programs and so forth. There are no changes to the displays settings, still 1280x854 and colors "millions". When I switch to thousand or 256 colors there is no significant change.

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.

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).

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?
The screen started by having the occasional 'white out' where it would be in use and a white screen would fade in for a few seconds then usually return to normal.

I am running maverick os 10.9.3 on my macbook pro
I had been getting horizontal small dashes across my whole screen.
Talk to an apple tech and he took me thru diagnostics and couldn't find anything wrong.
So he had me reinstall the OS and that was about two weeks ago and everything has been fine UNTIL today it started again..
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. Programs running in common were iTunes and Safari.
View 3 Replies View Relatedmy 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.

I have a 2 month old rMBP Mid 2014 and i am experiencing horizontal lines in the middle and bottom of the screen. For example, If i was browsing a site and then close the window you can still see parts of the website in the middle of the screen. I took the laptop in for the technicians to have a look and they a blaming it on the software,claiming that Gfxcardstatus is causing the problem. The problem still persists even with gfxcardstatus turned off. Does Gfxcardstatus do this? Is it the Lcd or gpu failure? Take a look at the photos ....

I have a problem with my screen - when there is something black on, I can see a faint mark of a lighter colour. I have tried to take a picture, please excuse the poor quality. There is nothing visible when the screen is off, even under close examination. Is it less visible when lighter things are on the screen, and invisible when the screen is white.
No drops or liquid spills. Will this go away on it's own? Any fixes?
so this has happened twice now in the past month, my mb is in screen saver mode and i wake it up to find that the color is off in the screen. meaning that the color settings changed and the screen has a swashed out blue tint to it. first time i restarted and all was good, second time i clicked on the preferences icon and then the screen went back to its normal setting. my normal setting is not the factory one but one of the ones that people said makes the screen look better.
so what gives, is the integrated chip dieing on me?
oh its a unibody that i got when they first came out, 2.0 processor one all factory
before switching to Mac, I used an "X-Rite Eye One Display 2" color meter device with software. You can find them most places like Amazon for about $150. The device should still work, but I can't find any software for it for the Mac. After going to the X-Rite web site, I could find no software at all for the Mac as it is only windows based.
Surely someone out there has used a color meter such as this one as they are quite popular especially for graphics artists that use professional graphic monitors. I am hoping someone can tell me how to use my color meter (USB), what software for Mac Leopard I need and how to save the color profile in the Mac OS.
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.
View 1 Replies View RelatedThis 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.

I have a Powerbook G4, and noticed a line (a thickness of a hairline) on my monitor displayed horizontally, about a length of 1/16 of an inch.
I know it's very tiny but I wanted to know what's causing this and if there's any way to fix it..
I thought it might have been a graphics card problem, but these lines move with the apps even in expose mode.
Its driving me nuts. I had this problem before while on 10.4 Tiger and now again on 10.5 Leopard (fresh install on new hard drive).
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).
I purchased a late 2006 intel core duo iMac 20'' with an upgrade to os Lion. I've been using it for less than 24 hours, and it has managed to freeze up on me twice, with a followed appearance of pixel abnormalities, horizontal lines, etc. I did my research and it seems to be a graphics card problem, which is a Raedon ati x1600 ,256 mb.

Well, I have a late 2008 13" Macbook Aluminum, (I've had it since Christmas of 2008) and just yesterday, I noticed a weird buzzing-like sound coming from the inside of it. There's also a faint vibrating feel to it. I felt around, and the vibrating feels like it's coming from under the middle of the keyboard more severely. The buzzing occasionally sounds like it's getting faster, and then slower, faster, slower, etc.
