So I am trying to setup my home system. right now I have the HDMI from my comcast box running directly into my smart TV. I tried running the HDMI cable from my HD comcast box to my denon HDMI in. Then i ran another HDMI cable from the denon monitor out, to my LED smart TV HDMI in. My smart TV just says searching for signal, and can never find one.... I know my denon receiver works, because i had it connected to my old DLP TV via A/V cable. Can someone please point me in the right direction?? Do I need a digital optical audio cable running from the comcast box to the denon receiver so my smart TV recognizes it?? Do I need to program my HDMI ports on my denon receiver?? If my HDMI ports are not being recognized, what is the 2nd best way to connect the Denon to my smart TV? Really confused here, and a novice obviously.
