how to use Dualhead/Dual Monitor Support with G400TV?

[Zulu88]

I have a G400TV, a RGB monitor, and an LCD monitor. The thing is that the LCD monitor acts as a regular monitor because the plug on it fits in any video card that a RGB monitor would fit in. I know I have to get a 2nd video card for it to work but from there what do i do? Has anyone had any expierence with this before? Thanx in advance.
