I would like to use my computor to play something on my tv/ 5.1 system tonight, but am having trouble figuring out how to connect it all together. I have HDMi ports on my cards (GTX titan) and plenty of HDMI ports on TV. My receiver is a pioneer vsx60 elite. I think i can just go from pc via HDMI to receiver and then onto the TV via HDMi as well? But im not completely sure and dont wanna go out and buy a longer HDMi cable for nothing. Any suggestions on seting up?
