Defaults to @samp{unset}.

Note: DeckLink SDK 11.0 have replaced the duplex property by a profile property.
For the DeckLink Duo 2 and DeckLink Quad 2, a profile is shared between any 2
sub-devices that utilize the same connectors. For the DeckLink 8K Pro, a profile
is shared between all 4 sub-devices. So DeckLink 8K Pro support four profiles.

Valid profile modes for DeckLink 8K Pro(with DeckLink SDK >= 11.0):
@samp{one_sub_device_full}, @samp{one_sub_device_half}, @samp{two_sub_device_full},
@samp{four_sub_device_half}

Valid profile modes for DeckLink Quad 2 and DeckLink Duo 2:
@samp{half}, @samp{full}
