4K Capture Mode
You can configure the bi-directional SDI connectors for input by accessing the Control
Screen and selecting Input Passthrough in the Default Output>Video Output menu.
Alternatively, when you launch an appropriate capture application (such as
AJA Control Room) and select a 4K digitizer in the application, KONA 4/3G will
automatically map the SDI ports to 4x HD(1080) for UHD. The inputs text will show
"2Kx1080" for "true" 4K.
