    Hi, i'm Juny

    I just bought a iMac Alu 20" 2.4GHz Intel Core 2 Duo a few months ago. I love it but i'm a new mac user. Now i have a problem with my display or graphics card i dont know. I made a screenshot and a photo to explain my problem.

    The first picture is a screenshot and it looks normal.
    Screen

    The second picture i took with my cell and thats how i view the screen.
    Photo

    As you can see i got some weird black/gray lines on the dark part of the wallpaper and some icons. The rest looks fine e.g Windows etc. but only some images give me some weird lines.

    I installed windows and linux on the mac and the problem remaind, it worked fine before, and sometimes it will switch back to normal for a couple of hours but then i get the weird lines again.

    Sorry for my bad english.

    Gr. Juny

    goto system preferences. click on display. set colors to millions instead of thousands.

    Do you have external speakers near the screen? And is there an Apple store close by so you can take it in in case you have to do that?
