I know that you can hook the 360 up to a computer monitor. Problem is, my monitor has no extra i/o plugs. It is hooked up to my video card through VGA. My video card has an HDMI slot, however, and I figure that I can take an HDMI cable and run it from my 360 to the PC's video card and the audio cables into a speaker system. I'm not sure about this though, and I don't want to waste money by mistake. So, will this work?
