My video card (Geforce 7900 GT) came with a cable that connects to the vid card and the other end splits into Red, Blue, and Green connectors, which I am assuming are for component cables. My Playstation 2 has component cables that I can connect to this cable. What I am wondering is what else do I need to be able to play my Playstation 2 through my computer/monitor? Do I need a tuner or anything just to use a device like a Playstation 2?
