Low-cost airlines are not in the habit of giving passengers an in-flight experience other than the actual transportation from A to B. This will be no different for Ryanair.
There are no interactive screens or free in-flight refreshments. This is offered for a fee in the form of hot or cold meals and sandwiches. Usually you won't pay more than 10 eur for a larger meal like lasagne . Non-alcoholic drinks will come out to 3 eur.
