Do I need a receiver with two HDMI outputs or just one?
I have purchased a Sony Bravia XBR-65X850D television and I have it connected to an older Sony Receiver STRDG720. I have recently gone to a DirecTV Genie with a mini that supports 4K. Because my receiver does not support 4K pass trough, I am in the market for a new receiver that supports the signal.
My question is this, do I need a receiver that supports two HDMI outputs if I intend to us ARC from the TV to the receiver? Can I simply get a single output receiver that supports ARC and then run a HDMI cable from that port to the ARC supported port on the TV to pass sound from the TV to the receiver when watching streamed shows and use the same output / cable to send the 4K signal to the TV when watching 4K shows from DirecTV?
Currently I am running an optical cable from the TV to the receiver to pass sound from the steaming services to the receiver and then I am running an HDMI cable from the mini-genie to another HDMI input on the TV and a coaxial cable to the receiver.
