A:Answer One receiver box has two outputs, one for HDMI interface and one set of jacks for video plus audio output. I have not tried this, but you should be able to run two TVs from one box, IF they are on the same channel, say, you wanted to watch the game in two different rooms. Otherwise, you need one box for each TV. I believe the maximum Orby recommends is four boxes. Of course, you will need the appropriate splitters that Orby recommends.
