Works well, but why no output cable that?

I had ordered my part, as I with the acquisition of a new receiver now wanted to connect three devices via HDMI to the TV, my old distributor but only two had in ports. The unit works with two devices (receiver, DVD player) properly. Unlike its predecessor, where I had to manually switch, automatic switching works flawlessly. However, I was able to try only two devices that the third HDMI cable need a connection from switch to TV. I've never seen that one (USB hub, etc.) gets a switch without cable to the terminal. Typically, these are (as the old switch) installed even fixed. At least one note in the description that belongs not out cable to, would have heard here. Must now again order and wait for cable. Therefore 1 star deduction.
