Restructuring virtual pinball after PC update. Monitor order 4 screens

[eracet]

I am in the process of rebuilding my virtual pinball for my legends pinball .

Found a backup but it didnt include a lot of things, and I ended up accedently formatting my old HDD..

 

So now I feel like a fool since I now forgot half of what I learned on order of screens and virtual pinball.

 

I have pinup popper installed. Future pinball, and virtual pinball.

 

There is a Full screen main , DMD screen small above that, Backglass, and a monitor for a topper.

What order do these need to be in and what settings will help on future pinball. Also what do I need to set up on visual pinball.
