If the interface card has multiply cable connections then it has
more than one monitor interface. Otherwise you will need another
interface card. On the laptop you have an internal monitor (screen)
and a video interface connector. The key combinations control which
monitor is being used, and on all I can remember one of the combin-
ations is both, but I don't know if you can use them for different
displayed applications like you can with multiply monitors on a
desktop.
