Mac mini M1 2 displays plus sidecar as 3rd display

Actually, you can drive three monitors with a 16 GB 1Mac Mini.

The trick is to connect each monitor to a different type of port on the Mac Mini, I.e. Thunderbolt, HDMI, and USB.

My flight simulator has three monitors, plus two iPads. The latter are connected via Bluetooth.
