I can get OBS to capture the play field just fine but can't figure out a way to capture the Dot Matrix and Back Glass which is on a second monitor.

I figured out a work around to just capture the entire monitor and crop out what I don't want shown on stream. I do this twice, once for the glass and once for the matrix. So I can move them independently in OBS.

Is there a way to specifically capture the back glass and dot matrix as individual sources? Or is the current set up I have the only way of doing it?
