A1 and External Monitor
 

I am trying to connect up my A1 via it's BNC connector to my 9" LCD teleprompter monitor. That way I can use the little TV monitor for the teleprompter AND as a monitor for my camera when not in the teleprompter.
So far the setup has not worked with the camera. The teleprompter monitor has a "F" connector (which is like a standard cable TV input). I have tried switching the V2 switch to no avail.
Is there stuff like native resolution etc. that may be the cause?
