Transparent line across the top of QuickLook previews

http://img107.imageshack.us/i/picture1wgl.png/
The link above shows this occurring in TimeMachine. I often see it previewing pictures or videos. How can I fix this?

Very interesting...
You might take a look at the display preferences... my only thought is that you have it set to something that your display doesn't like, but that doesn't explain why it's not there all the time.
Does this persist when you log in as different users?

You can try Resetting the iPod, won't work, if LCD screen is damaged or the display chip surface mounts has gone wobbly, which mean going in for servicing.
Otherwise.
Press Menu and Center button for 10 secs till the Apple logo comes on, then release the buttons.

Why is there a line across the top of iCAL 5.0?

why is there a line across the date on the iCal page after I installed Lion?

I got rid of the line by shrinking the calendar on the secodary monitor. The line doesn't appear in the full screen view nor on the primary display (MacBook). so if I don't want the line, I live with a view samller than the monitor screen :-)

How do I get rid of this black line across the top of my screen...

There is this black line that stretches about midway across the entire top of my screen... I read something about reseting my PRAM and I did that but it didn't remove the line... any insight on what is wrong with it and what needs to be done??
Thank you!

Is your Mac still under warranty? It sounds like a hardware failure.

I want to delete two lines across the top of the browser page. One is an inbox search window, the other a yahoo search window.

The two lines I wish to delete are toolbars.

Is there any text in that gray bar?
I see some buttons on it, do they have a tooltip?

At times when I am on a website, the cursor freezes and i have to shutdown and restart the processor efore I can proceed. Also, I have lost the toolbar and address line across the top of my desktop.

This occurs at least 4 or 5 times a day. I can do nothing when this happens. I don't know if this is a Firefox or Vista problem. I click on a link and it does not go but just sits there saying connecting.

How do I get rid of the thin line that goes across the top Persona background image.

There is a 1-pixel wide light grey line across the top Persona background image between the navigation toolbar and the bookmarks toolbar from left to right. Nomatter whatever persona I have installed, it is there. Same thing also when i hover on any other Persona at Getpersonas.com. It is not there when using any other program and not when only showing the desktop. Only when using FF4. My PC is a HP Pavilion dv6000 laptop using Windows Vista. This is not a monitor issue nor a graphic card issue since it only shows in FF.

for me, it happens on a maximized window. when i do restore to window, the line disappears.

Help! I've got a white line going across the top to my I pod

I have a 80gb classic ipod and I've got a white line going across the top. it is extreamly annoying and nothing can fix it not even restoring my ipod what can i do

That sounds possibly like there are dead pixels on the screen. I am not too sure about what type of screen is in the new iPods, but on my Sony PSP there are white spots in places, which I was informed were dead pixels. Sony mentions it in their literature regarding the PSP.
You should be able to take it back to your Apple store, and they should be able to take a look at it for you.

Thin Black Line going halfway across the top of the screen

Hi - I've exported a sequence from FCP. It's DV Pal 720x576 anamorphic 16:9 lower field dominance. I used compressor to create the mpeg 2 file for DVDSP. I used the Best Quality DVD 150 min setting. The problem I'm having is that when I export the file from DVD studio pro I get a black line going halfway across the top line of the video. I suspect it's either a deinterlacing issue or a field dominance problem. But I'm really stuck on how to sort it. Any ideas would be really appreciated. Thanks very much.

Something like this?
................................................................................ ........... (might also be mirrored horizontally)
That's the Half Line Offset and is a characteristic of interlaced video, not an issue or field dominance problem. It's quite complicated to explain and probably not surprising if you have never seen it before as it won't be visible on a regular TV set.
Short article here: http://lipas.uwasa.fi/~f76998/video/modes/ Look at the section "The "active" part of the signal". There's probably plenty more on the web, now you know what it's called.
What can you do about it? You will need to view FCP's output on an external interlaced monitor that is capable of displaying in underscan mode so you can see it.
Then you can use the crop controls to snip it off.

Lines across the screen

I have noticed for the first time today (after I have been working on my iMac for a long time) that there are horizontal lines across the whole screen from the top to the bottom. First I thought they would only be on the picture of my desktop background, but then I opened iPhoto and saw the lines on every picture I opened. So those lines are there on the screen and and not only on the displayed image. Really annoying!!!
Unfortunately my iMac is not under guarantee anymore...

I have this too! I just bought this iMac a few months back. These screen are having a lot of troubles from what I am reading. My horizontal lines are not that bad, but you can notice them.
I might sell these computer off quick as apparently the quality of these screens is a nightmare.
