VR for projection environments?

How did you manage to places all these views to different monitors? i am doing something similiar right now and could need some code examples.

I need some advice about how to use quad buffering. I read a thread that said that it was implemented in 4.8 but i cant find any further information about that unfortenately.

Here is the thread: Unreal Engine on a multi projector wall display - Architecture - Epic Developer Community Forums

Thanks in advance.
