Im getting a second 17" cinema display for my dual 1 ghz powermac G4 MDD. I just wanted to know if I needed to get any sort of extension or converter to make it fit on the second display port on the back of the computer. I have tried plugging in an old crt to it with the converter that comes with the computer but i dont think that it would fit a cinema display. Does anyone know what i need? A link or a name would be fantastic. thanx guys.
