I have a 1st generation 17" albook, i use to be able to connect my powerbook up to my 23 cinema display no problems... now whenever i connect it up, My cinema display shows a black line down the middle of the screen, and the screen is really fuzzy i cant even make out what the text is cause its so fuzzy . Does anyone know what is going on? I checked all my connections and its not that... i tried connecting my gf's powerbook to it, and it shows up nicely, but when i connect my powerbook, theres a black line down the middle and the graphics on my screen are very fuzzy... what can it be, please help! Sigh
