There are monitors which only have three BNC inputs and which use composite synchronisation (‘sync on green’). This circuit has been designed with these types of monitor in mind. As can be seen, the ...

The 5-BNC cable and the VGA connection cable both send data to one device from another by transmitting an electric signal. However, there are significant differences in the way that they are ...

The BNC version is preferable. The reason why is the HD-15 connector is not 75 ohms in impedance like the spec calls for - so you lose about 3db of signal per VGA connector, while the BNCs are true 75 ...
