My pc has a dvi, vga, hdmi video card. Currently the vga & dvi connect my pc monitors. I want to be able to connect the hdmi to my tv as a 3rd monitor when needed. I have a Denon AVR-S500BT receiver. It has several in ports but only one out. My equipment to connect are the tv, direct tv box, ps3. I want audio and video from pc to play on the tv when needed and also be able to switch to direct tv. Is this possible and if so whats the correct method?
