nope, my g-card has 2 inputs in the back so i can plug 2 screens into it, another option if u dont have a g-card with 2 inputs is get a SLI or crossfire card and you could do it.
Then all you do when both monitors plugged in is go onto desktop poperties and settings the on yer display you should have 2 screens when u cick the expand arrow. Go onto yer secondary screen and select the tick box for
Extend my desktop onto this monitor
and then yer other monitor should spring to life.
May do it with laptops so yer laptop screen functions as a secondary monitor.
Anyway good luck.
