Change arrangement of iPad used as Sidecar Display I have an iPad Pro (2018 3rd Gen) that I'm using as 2nd display with my Macbook Pro (2018).  I can enable it and it works well, but it's on the wrong side of my Macbook and there's no options in Sidecar to change the display arrangement.

How do I change the monitor arrangement of my iPad relative to my Macbook?
Sidecar has no settings to change monitor arrangement. You only enable the iPad as an additional display in the Mac's System Preferences.  You still have to go to "Displays" in your Mac's System Prefs to change the arrangement of the iPad as a display relative to your Mac.

After (2) days of dragging things in the opposite direction to the iPad display it finally occurred to me to check Displays...  D'Oh!
