I didn't know you could do multimonitor setup with m1 air. Can you share what your setup is?

I think it's called Displaylink. yet to try it with this particular benq but I know it can be done. The total output pixels are limited though so I doubt what the limitation of the Air is. but 2 24 inch 1080p should be doable.
