A:Answer The one connect box is a separate box that you connect all your inputs too. HDMI 1 2 3 4 Power cable, optical, USB. You have only one cable going to the back of the tv that plugs in the one connect box. So as an example if you hang you tv on the wall you can put the one connect box in your entertainment stand and plug everything up with out having to put all them wires going to the tv through the wall. I have this tv with my one connect box on top of my AC infinity AV receiver and it’s perfect for what I needed.
