    When starting up, the screen is sometimes broken.

    Is this a graphic card problem?

    Looks like it to me. What happens once it boots all the way up?

    In my case when iMac rebooted every 3 times, it shows up.

    I decided to return it again because iMac received first didn't show this problem up.
