Technically this is FAR from a dedicated HTPC (lives 70feet away from the theater room), but this best fits here I think. I will try and be brief. All I want to do is go from my computer to the theater room and get the best sound/picture possible. Currently that is easy, I have a 75ft long (Redemere) HDMI running from the computer (dual GTX 1080s) to the receiver in the theater room (Yamaha RXZ11) and from the Yamaha, to the projector (JVC DLA RS65). All works great. BUT, in a couple weeks it will all come crashing down when I get a Sony VW665ES. 4k. The Yamaha won’t process a 4k signal but other than that it still bests many of the finest (consumer grade/non-seperates) receivers out there today. I see NO reason to get rid of it UNLESS I can’t get what I want. So, how do I get a 4k (60hz) signal to the projector for video and still get the HD audio to the receiver? I am already aware just getting the signal over that distance may not be a picnic but I am willing to try just about whatever it takes (that doesn’t involve a new $5000 receiver) to get it done. Never tried HDMI over Ethernet but may look that direction to get the signal just…..into the room. Any suggestions for getting the best signal possible, then getting it to both projector and receiver???
