Advertisements OK....this is complicated...but here goes. I want to control my whole setup with the logitech Harmony hub. My tv is the Sony Bravia A8H OLED, and my Surround sound system is an Onkyo 4K ready receiver, and of course my Tivo Roamio. Question #1...which is better....run my HDMI to the back of the TV, OR do I run it to the Onkyo and upload it through the Arc HDMI ports between the TV and the Onkyo? Question # 2...I have tried both ideas and I can't get the Harmony remote to see the input of the Tivo in the TV.
