I've got an issue.
I have a Blackmagic UltraStudio Express connected via Thunderbolt to my Avid Media Composer Editor. The goal is to have the Video playback be seen on a second monitor via SDI cable.
It's the latest version of Avid Media Composer
It's the latest Black Magic drivers.
The Hardware specs on the editor are rock solid.

I am not a Media Composer guy. I'm the IT guy. Is there a setting to get the Blackmagic to output the playback to the SDI connected monitor? Is there a setting in Media Composer that I'm missing?

This is come down to me to fix, and I'm at a loss.
HELP!

There is a Hardware Enable / Disable button which lives below the record window in a default setup.  Perhaps that is in the disable state?
