Assuming I want to use the virtual cockpit or an outside view across three monitors, can P3Dv4 do this:

                   ----------------
                  |                |
 ---------------- |     screen     | ----------------
|                ||                ||                |
|     screen     | ---------------- |     screen     |
|                |                  |                |
 ----------------                    ----------------

And (hence) this:

              ----------------
             |                |
 ----------- |     screen     | -----------
|           ||                ||           |
|           | ---------------- |           |
|  screen   |                  |  screen   |
|           |                  |           |
|           |                  |           |
 -----------                    -----------

If anyone has tried X-Plane 11 with multiple screens (not nvidia Surround), I basically want to know if P3D can be made to behave the same.

Yes, apparently it can. But the setup is far from intuitive :(
