PC to HDTV
 

How do I connect a pc to a Panasonic 37" 1080p Flat-Panel LCD HDTV. I have a Nvidia GeForce GTX 260 oc (GC), on a Nvida nForce 430 (MB). The card and the mother board both have the spdif but the connector on the motherboard has 3 pins not 2? The spdif connector has 2 (2pin) female ends. And if I do connect them to each other , can i us the dvi to hdmi converter and plug in to the tv and get video and sound?
