HDMI 4x4 Matrix

I have a 2 X 8 HDMI set up in my house. It automatically selects the active input signal (from the 2 choices) and sends it out to the 8 TV sets. When ever the power goes out I have to go to each TV and select the HDMI 1 input and then unplug and repower the HDMI splitter box. That is the reboot sequence that I use.
