I have a case where I would like to extend a display to two airplay devices. I thought I could do it by enabling homekit, and assigning both devices to a room, then hoping that room would show up as a display device in the display manager. However, I do not see that room appear. Is there a way to do this? Any other way? The point is to drive two wireless displays from a macbook, but it must be recognized as a display device on the mac, because that is how Propresenter uses display outputs. I can do a single wireless display no problem, but I cannot select two wireless devices directly in the display manager for this purpose. It only allows one.
