Open a specific display be by default when connecting to a server/laptop

I use Royal TSX on macOS to control another MacBook Air laptop. This target MacBook Air has 2 displays: one is the laptop screen, and another is the external screen. The external screen is configured as the primary display. When I connect to the system, it shows a combined view of both the external monitor and the laptop display. I then have to select Tab –> Display 1: 3008 x 1253 in Royal TSX to only have it show the external display. I would like a way to start the session and have it show Display 1: 3008 x 1253 by default instead of me having to select that display every time.
