The term is component video, and is where you get the ability for Hi-def on the compatible TVs. I'm currently working on getting my TV to synch up with my ATI All in Wonder 9700 Pro card in my multimedia PC. My first attempt resulted in some, shall we say, unexpected results. I finally had to back it off to the S-Video, untill I can figure out why the component video didn't work like it was supposed to. What I did see with the RGB cables looked promising, if I can figure it out.
