Multi-Monitor Display (ndisplay) - First Person Navigation

Can anyone point me in the right direction towards figuring out how to get a First Person character working with ndisplay?

I’ve got an entire 3-wall cave environment working well, however the default game mode that the documentation says to use is “DisplayClusterGameModeDefault”…any attempt to use anything other than this mode causes the setup to stop working in the cave environment. I’m at a bit of a loss, because free-flying through a level isn’t what I want to do, but I can’t figure out how to duplicate the “DisplayClusterGameModeDefault” to modify things such as the Default Pawn Class “DisplayCLusterPawnDefault” or the Player Control Class “DisplayClusterPlayerController”.

Anyone?
