I have a Blackmagic Decklink Duo 2. I have set its connector mapping to 4 individual ports using the Blackmagic Desktop Video Utility.
I can output from all 4 SDI ports using other software such as Blackmagic Media Express, but when I try to do the same from TouchDesigner Commercial the Video Device Out TOP lets me select from all 4 ports but only ports 1 and 2 successfully output to a monitor. There is no output from ports 3 or 4.
I am using the latest TouchDesigner Commercial official (2020.26630) with Blackmagic Desktop Video 11.6 drivers on a PC with Quadro RTX 4000.
Is there a way to fix this?
Thanks very much.
