Monitor 3G Not Showing Up In Device Manager

Hi there!
Trying to get the Monitor 3g to work but it's not showing up in my Device Manager.
I've installed Desktop Video 12 but I don't think windows itself is recognizing the device.
I've tried following the steps in these threads without any success:

The 3g is receiving power through the thunderbolt, it's little light is lit up, but it's just not talking to the computer. I get a "no input detected" on my monitor when it's connected. Desktop Video also says no video device connected.
I am on Windows, with my 3g using HDMI out into my GeForce 3070.
Any assistance appreciated
