setup iPad to display on a quad monitor set up

I am looking to purchase a monitor for the sole purpose of displaying an iPad for instructional purposes. I know I can do this using AppleTv and Mirroring but my question is can I use a quad monitor set up in a way that would allow me to display to all four screens at once (for instruction) but also allow multiple iPads to display (up to 4) at one time (such as student iPads)

I am lost when it comes to hardware so please try to use "dummy" terms lol

If this would fit better in another forum let me know, thanks!
