AFAIK, those with only one standard connector, unless that connector is a 
DisplayPort, can only ever be used for displaying the same thing on each screen, 
typically called mirroring.

Many graphics adapters have multiple output ports that can be used 
simultaneously, and these can typically be configured to produce entirely 
unrelated things, or different portions of a single desktop too large to fit on 
one screen.

Some gfxcards are intended to be used with a special cable that splits the 
signal into two discrete ports. Those that I have work the same way as cards 
with multiple output ports.
