Vertical Grey lines appearing on screen

Smudgy type grey lines appearing on right hand side of my imac screen , they run from top to bottom with varing degrees. Can someone advise as what to do.

Run Apple Hardware Test in Extended Mode, if you get a error code then take it to your local Apple Store or AASP for a repair estimate. Chances are it's your graphics card failing. If you would like some additional information please read LCD displays common problems.

HP Notebook PCs - Entering Safe Mode (Windows 7)Hi , Welcome to the HP Forums!It is a superb place to find answers and suggestions!
For you to have the best experience in the HP forum I would like to direct your attention to the HP Forums Guide. Learn How to Post and More I understand that your display has vertical red lines, sometimes it will work fine sometimes for 2-3 hours.If you connect an external display and the same lines appear on it. Have you ran the Windows troubleshooter? Have you ran the HP Support Assistant ? Have you looked for a HP driver update for the graphic card? As the lines appear on the external also I would run a hardware test on the computer. HP Notebook PCs - Testing for Hardware Failures (Windows 7, Vista) Have you checked for viruses and malware?

I have a macbook pro 10.6.8. The screen displays vertical grey lines how do i fix it?

I have a macbook pro 10.6.8. The screen displays vertical grey lines. I tried Crtl.command.eject... Did not work. I tried Command.crtl.p.r. way; Didnt work. What is wrong with my mac and how can i fix it?

NVRAM reset is command, option, P and R.
Restart the computer and immediately hold the four keys down. Keep holding the keys down, and let the Mac chime three times, then release the keys. Be patient it could take some time.
That being said what you describe may be a hardware issue, so the NVRAM reset probably won't work.

Satellite M65-S9063 - Vertical white lines appearing down the screen!

Hi all - any ideas...
Model M65-S9063 Approximately 3 weeks ago a vertical white line appeared down the screen, it's around a mil thick.
Then yesterday a second one has appeared, slightly thinner this time. They're always there even after a reboot! It doesn't look as though any video is being displayed as they're always white. I was wondering graphics card perhaps? Or maybe the LCD itself?
Anyone seen this before??
Many thanks,

Hi!
You can simply determine the reason of this issue. Connect an external monitor the notebook and see what happens.
If you can notice the same error on the external screen, its a problem of the graphic card or display driver. If you dont have this issue on the external screen, you should go to an authorized service provider for exchanging the internal screen.
If you use a non Toshiba display driver you should remove it and test it with original Toshiba drivers.
I hope I could help you a little bit.
Bye

I have vertical colored lines appearing on the Mini Ipad screen

I have vertical colored lines appearing on the Mini Ipad screen

I had the same problem with my first gen ipad mini. The solution was not to do a hard reset, but instead to push the sleep/off button until the red slider appeared, then slide to OFF. Wait a few seconds then push the sleep/home button until the Apple logo appeared. The lines were gone. I called Apple Support and they wanted $19 to troubleshoot over the phone and $99-$199 to bring to the nearest Apple store. This may not be a permanent fix, but it resolved the issue. I purchased my ipad mini from a local electronics store in May of this year. Believing it to be new and still under warranty I called the AppleCare store and discovered that it had "previously" been purchased in November a year ago and was no longer in warranty. As stated, I've had the device since May and it has worked wonderfully until today when I turned it on and it had colored vertical lines displayed on the screen. The lines would change color at times and even became a solid black stripe. The strange thing was that when taking a screen shot the lines were not noticeable and didn't show up on the picture. The Customer Care support tech told me to search other display issues. On one of the support threads it had something to do with videos/video apps and that is where I saw to do the SLIDER OFF. It worked even when the hard RESET had not.

I have a vertical red line on my screen - what's causing this?

Have you tried this?
Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.

The screen resolution in 1920x1200 dropped on my MacBook Pro 17". Seems like I have not the same pixels. There are also vertical, thin lines on the screen. Makes the screen look milky. Anybody knows what's going on and how to fix it?

imac 21inch 2010 on boot vertical green lines then white screen ,will not load can anyone help please

Howdy carliosa,
If your iMac is not starting up normally you may need to do some checking to make sure things are working correctly. I would suggest starting with the steps in this article -
Resolve startup issues and perform disk maintenance with Disk Utility and fsck - Apple Support
Thanks for using Apple Support Communities.
Best,

Thin vertical lines appearing on screen, since wakeup from sleep mode.

My Mac G5, 2GHz, DVD-R, 1GB DDR RAM, OSX 10.4.10, ATI RADEON X800 XT has recently developed a display issue. On start-up the screen shows vertical lines across the entire screen. The colors of theses lines is varying from green to black, depending of the background color. The lines are appearing from the grey loading screen and when a profile is logged in.
Shutting down and restarting doesn't cure the problem, nor does staring in safe mode nor starting up from an install CD. I also tried re-installing the operating system, but I get the same result. I tried another monitor but I also get the lines on screen. I verified all the cables and that the graphic card is well in place in the pci slot.
If I change the resolution, I also get thoses lines but they change place on screen. Also, if I set the colors level to 256 colors, I get very little single lines but If I set the color level to the highest (36,7 Millions), the lines appears in group of 5+ and are all over the screen.
I tried taking a screenshot using the shortcut cmd-shift-3 and I can see the line in the pictures. Also, if I take a screenshot of a window that is behind the window in the front ( using cmd-shift-4-space ), I dont see the line on the screen shot.
I started to have this problem when my mac was woke up from sleep mode and the problem has persisted since then.
I guess my problem is the graphic card but I would like an external opinion before I got buy another one.
Thanks

Any new results?
I'm having the same issue. Looks like this, but at a slight angle and different RGB colors (almost like JPG artifacting).
Started this evening after a cold boot. I just put my X800 XT Mac G5 edition in 2 weeks ago. No real heavy use either, as I've been gone for a week.
Looks to me like bad VRAM (according to TechTool Deluxe). I'm running the AHT now and will hopefully come to a final conclusion soon. I did test my 20" Apple monitor (DVI) with my laptop and there was no problem...so it is definitely the video card. Not sure if the aforementioned ATI ROM extender will fix it or not.
Much luck to all of us who are having this problem.

Pink vertical lines appearing on screen

I have a G5 about 2 years old. Recently a pale pink vertical line appeared down the screen, another about 2 weeks later and today a third line appeared. They do not affect the screen's visibility, but I wander if anyone else has found a resolution to this minor problem (without having to go out and purchase a replacement.

Hi Ocean swimmer-
Greetings and welcome to the Apple boards.
Makes sure to check the cable connections at both ends.
Which monitor do you have? If you take a screen shot do the lines still show up in the same place?

Why is there a grey line on my screen?

Out of the blue, a thin grey line has appeared on the left hand side of the screen of my iMac. It's a vertical line that sometimes changes colour. I've had the iMac for less than a year, there's been no water damage or dust, the line has appeared out of no where, what do I do?

If it's covered by warranty (1 year) or AppleCare just take it in for service, either the graphics GPU has failed or the display itself has an issue.

Ipod classic has grey lines on the screen

I noticed today that my iPod has a few shortish grey horizontal and vertical lines on the screen. They are approximately on the spot where the picture of the battery shows up when the screensaver-thingy shows up. They aren't huge and don't really make using my iPod impossible but they do bother me. I've been using my iPod normally and I usually keep it in a plastic case to avoid the screen getting smashed in my bag etc. So the lines just.. showed up. Resetting the thing didn't help and the lines are always there.
What the heck?

I have had exactly the same problem for the last week. 4 horizontal lines. Just came on after I had synced. Have restored and no difference
