I have a nVidia GeForce 9800 GTX+ 512MB graphics card. When purchased it came with a component cable to s-video cable. I currently have an Xbox 360 that i would like to play on my flat screen monitor but i don’t know how to hook the cables up. Can someone show me how to do it step by step please? I have a component cable that goes into the video card wire but it’s not showing up.
