You need to get specs for delivery from the technicians responsible for the display.
There are a lot of possible variables here, often more related to the playback device than the display itself, so we can't accurately answer the question for you.
I will add that the comp you work in and the output you deliver need not always match. You can work in a design space that's separate from the actual display space when that's advantageous. I do this often myself.
