EDIT: The DUE only cost $32.00 so I connected the 4x20 LiquidCrystal IC2 display to 5V, GND, SDA and SCL and it works.
I purchased an Arduino DUE and I need assistance with choosing and connecting a display. I have 4x20 LiquidCrystal IC2 display that I bought and used with Arduino UNO rev3 but I don't know if they will work with the DUE. This is not my forte so please excuse my ignorance.
