Syncing score with cubase

Hello everyone

I am new here ,

44 years old and a composer / musician.

Does anyone know how it works , what do we need ?
I’m trying to figure it out for years

I have cubase with a audio recording of some parts and on there are also some movie parts that has to be projected
, it had also a tempo track so I can midi sync it
I also have a written score (written in finale)
of the parts that have to be played live

What we wanne do is to put screens/tablets or ipads for the musicians , where they see only their score parts in sync with the cubase that is running

I know it is possible , I have seen the concert war of the worlds and they used screens

I just don’t know how to start , what soft/apps I need etc etc
