Starting with version 1.54 Nobe Display supports NDI streaming. This means you can share your video signal with anyone in the world using any 3rd party streaming application using the built-in system video input device (webcam).
First step is to download and install NDI Tools from NewTek:
Once you have Nobe Display installed, start DaVinci Resolve, go to the Timeline Node and apply Nobe Display Connect OpenFX plugin:
Next, open Nobe Display either from /Applications in macOS, from the Desktop shortcut or directly from the OpenFX inspector by pressing "Open Display" button and hit "Connect" button in Nobe Display application:
Once you do that, you should be able to see the live preview from DaVinci in Nobe Display window. Go to Options / NDI to see the current status:
Now, launch NDI Virtual Input app (Applications folder on macOS or menu start on WIndows) and find our Nobe Display Connect source in the Sources menu:
From now on you should be able to see a new video device in your system and in the apps compatible with the system video input device (Zoom, OBS, Skype*, etc)
