Shmister :
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?
For audio using your reciever to get 5.1 you will need to use Toslink from your PC to the reciever.

For visuals you can run HDMI from your GPU to the reciever thats fine. Your reciever has an output HDMI port that connects to your TV. You can also run directly to the TV with HDMI. If possible investigate your TV for a DVI input. Most GPU to HDMI connections are limited to 30hz and if your TV is a plasma or a 120hz display it will run full bore on the DVI cable. HDMI is super limited gimic that should be avoided for visual connections when ever possible.
