    Green Line on my Monitor!
    Hello people!

    My 20 inch Intel iMac suddenly developed a green line in the middle of the screen, and it will not go away! HELP. I cannot watch my movies or work at all! This is outrageous!

    You need to check first to see if it's the monitor or GPU.

    Attach an external monitor to your iMac. Is the green line there? If it is, then you can assume it's a GPU problem. If not, it's your iMac display.

    Regards.

    I don't really have an external monitor to test this out on. Is there a way to link it to my Macbook and use the latter as an external monitor instead?

    No, because your MacBook only provides video out. Do you have a TV set at home? A late model TV can be used as a monitor if you have the proper cable and adapter. Either that or see if you can borrow a monitor from a friend.

    If your iMac is still under warranty or Apple care, it might be easier to make an appointment with the genius bar and let them trouble shoot it.

    Regards.

    I have the same green line. Luckily, it's off to the right, but is still annoying. Is there any way I can deal with this myself?

    How old is the iMac?
    This is a known issue on the first white bodied 20" iMacs, and Apple will still replace the screen FOC if asked.
