Hello DtotheJ,
with your card comes a small adaptor 4-pin s-video output witch a cinch-connector to the other end. You need a 75-ohm koaxial cable (like tv-cable) with cinch-connectors on both sides. Here in Germany i bought one for sat-tv, it is smaller in diameter and fits perfect to the cinch-plugs. At the tv-side, you need an adapter scart/video+audio in.
I had to figure out the right parameters in nvidia desktop (trial and error)
