Configuring DCS priority scheme
There are two priority schemes for putting composite sync (CS) on the separate VS and
HS sync outputs when digital composite sync (DCS) is selected through types SSST = 2,
6, or 11. This applies to both the VS and HS pins of the VGA connector and to the analog
component BNC connectors.
