 Loss-of-video fallback settings for each output
NOTE:
For each output, "Fallback Enable" can be set to "Yes" or "No."
1. Select "No" to disable the loss-of-video fallback for the selected output.
2. Select "Yes" to enable loss-of-video fallback and the "Fallback Input"
and "Delay" fields appear. The fallback input for the selected output
may be set to any one of the 16 inputs. Delay can be set from 1–99
seconds. This means that if valid video is lost from that output and not
restored within its "Delay" time, the selected output will be switched to
its fallback input.
