Secondary display window positioning

TLDR: I would like to set the window position of secondary display, including being able to set it to the bottom layer.


For context:
We used Presenter live for the first time this morning, overall it went well. Our system is set up with 3 displays, one for the operator, one for the main display for the congregation and one for a stage view.

We also live stream our service using OBS running on a dedicated PC. As we only have 3 video outputs we used to use the NDI output option within EasyWorship to send lower third lyrics to the second PC. We set an secondary output with the "Display" setting to window, captured it with a local OBS install and then used NDI to send the output to OBS on our streaming PC.
This worked, but the Secondary display showed up over the Presenter control UI. If there was a setting to set the position, and the z-index, I could have set behind the stage view.

Ultimately and a option to add an secondary display using NDI with alpha transparency would be the best option,.

(I posted this in another thread, but I think it's relevant here, also.)

Apparently NDI support is coming to Presenter later in 2025.

In the meantime, I think there are Mac applications like Deskpad (https://github.com/Stengo/DeskPad?tab=readme-ov-file#readme) and BetterDisplay (https://github.com/waydabber/BetterDisplay#readme) that allow you to create "virtual monitors" for Presenter to output to. These can be captured by applications like OBS and then streamed online or sent over NDI (using the OBS NDI plugin).

I haven't yet investigated Windows utilities that do the same thing, but I'm sure there must be some options out there.

I also haven't discovered a clean solution for getting an alpha channel out of Presenter, but it might be possible to have Presenter generate two separate outputs — one for the fill and one for the alpha/key, and then use something like the StreamFX plugin to combine the two into a semi-transparent video.

Cheers,
