Hi, I am playing with the Restaurant demo. I plan on using a single till with a touch screen monitor for the servers and a monitor in the kitchen for the preparers. I can't figure out how to set this up so that both monitors can be active at the same time. I want the till monitor to be active on the 'Sales' function and the kitchen monitor to be active on the 'Kitchen monitor' function. I've gone thru the help documentation and there is clear instructions on kitchen printer but very little on kitchen monitor. Can someone please tell me how to do this?...thanks
