Not really clear on what you are trying to do, but it sounds like you are trying to get 2 differing displays out of 1 computer?
It is possible to have 2 monitors (with great difficulty - as I am currently finding), but you won't be able to do something like multiplayer gaming on 1 computer with 2 players using 2 monitors.
But hey, there's always a deck of cards - or everyone's favourite, monopoly...
