Sporadic strange lines in my screen

It happens sometimes that strange lines appear in my screen for some miliseconds XD. It's a short time but it finishes being unconfortable.
I'm using xorg with xf86-video-intel, i've got direct rendering and i'm using the gnome desktop. Any idea?

i have the same problem. about a day after i got my ipod little lines appeared on the screen, when i have my ipod on it looks like i have little lines of water on the screen so it makes the pixles look messed up. i guess they must be sratches but i dont want a big protective case for my ipod. any suggestions?

Strange lines on my screen

Recently I have noticed strange lines appearing on the screen of my MacBook Pro - they appear and disappear randomly. I have noticed it especially on and around icons, as well as around the edges of Finder windows. Today it escalated to the point where I couldn't see anything on the screen (see attached screenshot). My computer is about 3 years old and I haven't had any problems with it.
I just recently upgraded to Mavericks - could this have anything to do with it? The problem started shortly thereafter.
Please help!!

Disabling "Automatic Graphics Switching" seems to work to resolve this problem.

Strange lines on my screen - graphics card issue?

Hi!
I'm totally new in this forum but from what I've read you guys really knows a lot about macs.
I have experienced some flickering lines appearing on my screen especially when watching graphic intensive webpages or changing resolution in games or switching to full screen on flash-based video websites. These lines are often accompanied by a low twittering noise from the computer. Sometimes it's just a few lines but sometimes the whole screen is covered. Logging off will fix the problem temporarily.
My theory is that my graphics card is giving up. What do you think? Is there something to do about it other than to change the card?
I have run tech tool 5 without any errors.
I would really appreciate some help. I took a pic of the screen with my iPhone but I suppose I can't upload it here for you to see?

I've seen screens like that due to a seating problem with the card.
As you describe, logging out, or a restart would restore the screen.
When I first saw this behavior, it was when the machine was awakened from Sleep......
Reseat the card, and when tightening the hold down screw, make sure the card does not pull over to one side as the screw is tightened.
The clockwise turn of the screw can move the card over (down in the G5) which can cause some pins to have weak contact.
Also take care that the card is not tilted forward at all.
Pulling on the cables can cause the connectors toward the rear of the card to slightly lift out of the slot.
If, after cleaning, and adjusting the seating of the card, the symptoms continue, or especially if they worsen, the card may be considered compromised.
I would also try running the machine in a new user account just to be sure that a software problem within the account isn't culprit.

Strange vertical lines across the screen

2-3 weeks before I started getting some vertical lines across my screen which don't show up when I take a screenshot with Grab. So I took a pic with my camera to show the problem.
I have a white 17" iMac 2Ghz with 1GB RAM with Mac OS X 10.5.5

I Hate to say this but.... welcome to the club check this thread out...

Strange lines and dots with Radeon 1900XT

I have a strange problem with the output from my video card.
My setup is a Mac Pro 2.66 with a Ati Radeon 1900XT card and two 20" cinema displays.
Sometimes, and for some reason often with dark grey tints or black the videocard renders a single pixel (red, green, magenta as far as I have seen). At first I thought it was a stuck pixel in my display but when I drag the problematic window the pixel moves too (I can also screencap it). If I move the window slowly I see a trail of pixels appearing. I also get lines (not full screen width) with sites as youtube over the video (but wider than the video). Anyone familiar with this, or suggestions? Can't tell if it is a hardware or software failure, after reboot it doesn't appear for a few days.
cheers Trepn

Having just discovered this thread and having very similar symptoms to everyone else, (lines appearing etc - pic here - http://theappleofmyi.com/blog/?p=1301, I updated the firmware on the X1900 Xt, which did nothing to help....
Then out came the card and I used a rocket blower to remove a HUGE amount of congealed dust from the fins and as I type this, it seems to have solved the problem!
So, I urge you all to follow the advice given by a few people, and clean your card out!

Strange lines appearing behind itunes

I went away for the holidays, and when I got back I booted up my 2006 iMac. Today for the first time, there are strange lines appearing behind iTunes whenever it is open but not the active window. I tried quitting and restarting iTunes, but the lines come back. I wish I could upload a screen shot of what this looks like on my desktop, it's very weird. It does not happen behind any other program window. Only iTunes. The lines appear as if they are extensions of the iTunes window formatting, in line with the side bars, etc. Has anyone else experienced this? Any tips for getting it to quit?

I just wanted to add that I am also seeing the same problem: strange lines around the borders of the iTunes window. The most obvious ones are a set of four vertical lines running parallel to both sides of the iTunes window, although there are other strange bits as well, mostly around the top corners of the window, as well as a single thin horizontal line above the top of the iTunes window. These unusual lines started appearing "out of the blue" sometime in the past few weeks -- as in, not right after an update or any other configuration change to my mac... The only change I can say I did recently was to update to OS 10.6.6, although I know others who are running 10.6.6 and aren't having this issue with iTunes. I also wanted to add that in my case, I only see these strange lines when iTunes is the active window. Further to that, updating to iTunes 10.1.2 does not fix the problem, unfortunately.

Strange lines

I create tutorials for a company. Ever since I started using
Adobe Captivate 3 (over a year), strange lines appear in the
rendered version of certain screen shots. These lines only appear
in a consistent group of screen shots. I have tried every angle I
could think of to get rid of them including:
Exporting the existing backgrounds and inserting them into a
new project.
Taking new screen shots.
Importing the project into Flash 8.
Pulling out my hair.
Again, these lines do not appear in the project until I
render it into a flash file and run it.

Strange hiss and dim screen at start-up

My imac has begun exhibiting strange symptoms. When I start it up from sleep or being turned off it makes a high pitched hissing/whine noise. The monitor is dim for about 1-2 minutes and I can see horizontal lines on the screen similar to a TV that is not tuning in a station very well. The noise and the lines last about 5-7 minutes. Can anyone tell me what's going on? My first suspicion is that it is a problem with the monitor but I don't know enough about this to be sure.

A few months back I Dropped my iPhone 4 and I cracked my screen and now i cant unlock my phone due to touch screen not working plus there are blurred lines across the screen and I can't see anything that it displays.
Now when I try too connect my iPhone 4 to iTunes on my computer at home an error message comes up saying that I have to unlock my iPhone 4 for it to communicate to my device.
But the problem is that I can't unlock my iPhone 4 because I'm unable to see the key pad and my touch screen no longer responds when I touch it.
I just want to reset my iPhone 4 back to its Factory Settings & start all over from the beginning.
How can I unlock my iPhone 4 with iTunes on my computer or any other option you suggest me trying.
Thank you in advance,

If you have had a "local guy "repair your iphone you will not get any support from Apple for warranty OR post warranty
If Verizon return it to Apple it wil not be handled by Apple
If Verizon also use unauthorised repairers you may be lucky
(Apple do not sell parts to local guys or anyone else )

Issues with lines across the screen, as well as freezing

Issues with lines across the screen, as well as freezing
Hello all
Got an iMac since January 2008 and I do like it a lot, even though it has some issues:
-- It displays (quite often) lines partially across the screen
-- Lines appear as well when opening applications or when menus come up
-- The system freezes more than I like to admit (more than my Windows/Ubuntu box)
I don't know if the freezing has to do with the lines that are shown on my screen. But I assume that both issues relate to some video card problem. I can't be sure - but that's what I assume from living with this issue day to day.
The line on the desktop (most of the time it is there before login) I can always get rid of by changing the display resolution to something else and then changing it back. Normally the line is gone, or, reappears on a different spot on the desktop. But repeating the procedure removes the line.
However, this does not mean that the lines are not showing up again when launching apps or displaying menus!
And since those lines appear to happen randomly, I think it's safe to assume that we're not talking dead pixels here, either...
About the freezing:
My iMac freezes sometimes when I move the mouse around, when switching desktops using "spaces" or when the zoom function of the Dock kicks in. Sometimes the screen goes completely black, sometimes completely white. The mouse, however, always works. But the system requires a reboot.
Again, this happens too often to feel comfy about it.
With my little knowledge of Mac troubleshooting I assume that there's something wrong with the ATI card that's built into my Mac. On the other hand, some people say that they started getting similar issues after updating their OS to Leopard. Again other people say that such issues stem from an ATI revision that is too old and the Mac should get a new ATI card. And how would that work? Isn't that an "all-in-one" machine with everything soldered onto the mainboard?
So, any help in this matter is greatly appreciated...
Cheers,
Rainer

Here are a few screen photos I've taken (not screenshots, as the lines are not visible when taking screenshots. I used my digicam to snap those...).

HT1430 Ipod touch (5th generation) w/ lines across the screen - now dead.

My son's Ipod touch (5th generation) had lines across the screen. I turned it off using the home + on/off button reset, but the apple never came back on. Now it seems to be dead. Not dropped, not completely drained, no water damage. Just dead. Any ideas?
I have also tried plugging it into my Macbook Pro, and iTunes does not find it.
ITunes is up to date.

Try:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
If still problem, make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

Line on the screen of my ipod touch 4th gen. Starts left of the screen as a blue (bright backgr) or red (dark backgr) line becoming white halfway and going across screen. Any ideas/solutions?

I have an irritating line on the screen of my 4th gen ipod touch going left to right. It starts out as a blue line (with bright backgroung) or red line (with dark background). Switching backrounds will also switch the color of the line. Sometimes it stops halfway the screen. Sometimes the blue/red line becomes white somewhere halfway the screen and continuing as a white line to the other side of the screen. It mostly starts out as a normal screen and when using the blue/red line appears and when using some more the white part appears.Mostly in the beginning the line starts flickering and becomes more steady after a while.
I have searched on the internet but can only find info on some pixels acting weird (stuck/frozen/dead pixels). This is a whole line of pixels not doing what they are supposed to do.
Anyone an idea what this could be and how to solve it?
Thanks,

Did you ever fix this? My daughters is the same. Treated with tender loving care, we reset to factory and it disappeared but was back again after 2 or 3 days. Still in warranty so going to take to the genius bar, however a bit concerned that because it belongs to an 11 year old they are going to assume she's damaged it.

My new iPhone 5 has black and white lines on the screen. It's not been damaged. I've tried turning it off but this does not solve the problem? Please help.

By far the most common problem hardware-wise seems to be scuffs on the aluminium. Yours is the first report of a faulty screen I've seen.
If you use the same Apple ID on both devices it'll sync whatever you want it to - music/apps/photos/messages/etc.
I've just switched from a Galaxy S3 to iPhone 5 (having already owned an iPad for a while) so I'm in a similar position!

My MacPro 10.6.8 has a thin green line on the screen.

My MacPro is just over a year old now and I have a thin green line on the screen. I hooked it up to my TV and on the second window (the TV) the green line wasn't there. Whats the issue? How do I fix it?

From what you are saying, sounds like a line of pixels out on the display.
Did the TV use the same connector on the computer? If not, swap the display with the TV. If you still have the line, it is one of the items that you swapped across.
Have you tried connecting the display to another computer? If so, is the line still there?
What kind of display is it? Can you swap the data cable and try a different cable, could be a cable issue.
Any adapters in use? If so, try swapping those to rule them out as a problem.
Did the TV use the same connector on the computer? If not, swap the display with the TV. If you still have the line, it is one of the items that you swapped across.
