ok Ive been using pro tools for about a week now and i really like it and learned it extremly fast. Now Im seeing that I am going to need an additional bigger screen. Ive read somwhere that it be a good idea to use 1 screen for mixing and the other for track editing, which to me is exactly what i'd be using it for but I just dont see how you can have the main screen on my macbook to show 1 thing and the other screen thats hooked up to the macbook show somthing else. Is that even possible? and last question what do these additional screens usually plug into? usb, firewire, express card?
