There are 2 ways to monitor the EX3 output with the monitor you are using: composite or component.
1) composite – use a 75 ohm BNC to BNC cable between the MONITOR OUT connector on the EX3 and the VIDEO IN connector on the monitor. This will give you an SD down-converted video signal. You can change between letterbox or crop in the VIDEO SET menu on the EX3.
2) component – connect the component video cable which comes with the EX3 between the COMPONENT OUT Mini D connector on the EX3 to the YPbPr BNC connectors on the monitor. You will require 3 female phono (RCA) to male BNC adapters. This will give a HD signal or MUCH higher quality although on that size of monitor it won’t be as noticeable. Again, output options are available in the VIDEO SET menu.
According to the monitor documentation, the BNC inputs on the monitor are self terminating.
