My 37ND only has 3 televisions and I'm not positive at the moment but I believe the HDMI switch handles 2 inputs and 4 outputs. I'll have to check this out a little later.
When I bought my coach I found they had connected the DVD into an output on the switch and 2 televisions into the input side. You may want to check your connections as well.
