Is nDisplay the best solution for a simple dual-screen game? (not split screen)

SETUP:
Hi! I’m starting from ground zero with Unreal Engine. My learning project I’m planning is a game that uses two screens, set up as a “Pepper’s ghost” effect which overlays the two screens using an optical illusion. The idea is that the “background” screen will display an animated backdrop that the user doesn’t interact directly with, but provides visual feedback for timing events in the “foreground” screen which will display the actual gameplay.

QUESTION:
Is the nDisplay feature the best method to use to develop this sort of setup?
Or is there something better/simpler?

THANKS!
