Output Properties; Set Output Video Properties - Lightware UMX4x4-Pro2 User Manual

8.11. Output properties

The following commands are setting up the properties of the output ports. If only one or a
few parameters have to be modified, the protocol enables to mask the other parameters,
so they can stay untouched. To mask a parameter use "x" or "X" as its value.
