Questions about 30" Cinema Display

[Mystic Gohan]

OK I have a Radeon 9700 128 meg card that powers my 30" Cinema display.

The problem is that there are like green streeks in the screen. Is there something I am doing wrong, is the card not powerful enough? I mean it can display it at 20xxX1600 resolution. Other then the little green marks that appear it doesnt do it all the time, just some times when I turn on the screen or reboot my Laptop.

Nevermind, I see you're on the new Powerbook which does have dual link dvi.

thats what is giving me the trouble, and the resolution that I run it at is 2560x1600, when I run it that high I get the green marks on the desktop.
