sigh, im not sure why im getting this problem when hooking up my pbook to my 23 cinema display... its not the new aluminum ones... but i get this black line runnning down the middle of my screen, and parts of the screen are fuzzy... im not sure what the problem is, my cinema display is new, i never had this problem before... it happens randomly, but now it is starting to happen all the time... when i reboot my powerbook, the screen shows up fine, clear, no lines, but when the login screen pops up, thats when the screen on my cinema starts getting fuzzy and that black line running down the middle and its really bothering me sigh. anyone have any idea what could be the problem?
