Andrew, The VNC "Display Number" does not have anything to do with the physical displays attached to your Windows PC, but is simply used to determine which port to accept VNC connections on.
Making only the primary display available remotely is a characteristic of any VNC 3.3 based software, which TightVNC is one example of. VNC 4 works correctly with multiple monitors, making the entire desktop (i.e. all monitors) available remotely. VNC Enterprise Edition provides the functionality of VNC 4, but can alse remote individual monitors, via the DisplayDevice registry setting. You would set this, for example, to "\\.\DISPLAY3" and VNC Server would then make only display 3 available rather than the entire virtual desktop.
