How to make iPad used via Sidecar display 2 instead of 1?

And in hindsight it probably did…

I have this Keyboard Maestro macro which opens Apps full screen. I thought it would do that on the “primary” monitor, but now that I actually inspected the macro I see that it uses:

  • the current monitor, if there’s only one screen
  • screen 1, if there’s more than one

That works fine when my MacBook is the primary screen, but I want Apps to appear on a larger external monitor (screen 1) (my regular setup in the office 15 months ago and also when working at home in my study room).

Now with the iPad and Sidecar (outside of my study room), the external screen is actually smaller than the MacBook, so I guess I need to improve my Keyboard Maestro macro to take the resolutions into account!
