† Master and slave devices may not display to the same eye simultaneously using
genlock alone because the 960
×
680 video formats do not use a feature called
“vertical sync elongation” to enable the fields to be distinguished. Using framelock
as well as genlock solves this limitation.
Genlock LED Indicator
The genlock LED indicator is located between the 13W3A and stereo connectors. The
LED illuminates when the genlock input is present and matches the expected
horizontal rate.

You must disable genlock on all slave devices before doing any of the

Changing the video format for either the master or slave devices

bothlock
) from a device, type:
