Turning the screens off is simple. Please follow these steps:
1) create a new template
2) in the background select source (defaults to PC)
3) Select the source to Panel off
4) Save the template with an appropriate name
You can schedule this anytime you want. I normally have the Off.scn template fro 0000 to 0800 and then from 1800 to 2400. This turns off the panel, but not the embedded PC which is normal as when the template at 0800 starts, the screen will wake up.
I hope this helps.
