5.9 Video output selection
The board has four outputs organized as two pairs, each consisting of one inverting
and one non-inverting output. The signal to each of these two pairs can be routed
either directly from the re-clocker
(“Through”) or from the audio/video processing unit
(“Processed”).

All features that requires modification of the video content (video generator, label
overlay, etc.) requires that the output is set to Processed. Note that when the internal
video generator is selected (either because it was selected as main in Video in, or
because it was selected as fallback for a missing input), outputs set to Through will
behave as if Mute was selected.
