Can I send two cameras to two displays at once respectively?

Hi, I am a newbie on Unity and I am trying to implement the projection mapping using unity.

So, I'd like to add two cameras to one engine and send them to two displays at once.

The rough figure is shown below.



I want to use a game window, but I don't know how to make two windows,
and I don't know how to display them on the full screen, not on the main monitor.

I'd love to get some help. Plz....
