X-Plane/Using multiple displays

The "supported" way to use X-Plane with multiple monitors is to use multiple computers on a local area network (LAN). Through the X-Plane internet options screen, you can indicate which computer is the "master", and which are the "slaves" used to display extra views.

Each machine needs to be running it's own copy of X-Plane (same version, same scenery, etc. - best to use file sharing to do this), and you must setup each computer to do this through the X-Plane internet options screen.

It is also possible to use a single computer with multiple monitors, by setting up the monitors appropriatly (in a grid formation), and setting X-Plane's resolution to the combined monitor resolution or portion thereof. This may work on both Windows and Mac OS, but is not officially tested to work. This trick may not work across video cards, and may require a single video card with multiple outputs.
