Speaking from a 320 F/O perspective.
While I agree with most of what's been said, I'm a bit surprised regarding one missing element.
Why not add a word about the weather ?
Imagine if it's a cat 3 takeoff. You have your alternate at, say 45 mins of flight.
If you takeoff, you can't land at your takeoff airport because it requires 2 PFDs.
You can land at your takeoff alternate (or destination if very short flight), because at least one of them is not cat 3. But during takeoff you don't have any time to analyse and guess if your screen problem will not extend to the other screens, or other systems of the aircraft.
Plus, during LVP, it can be good practise to increase a bit takeoff thrust from the max flex habit of blue sky weather. So you have more margin for stopping.
So if we were, for example, halfway into the high speed phase in cat 3 weather, I would expect the captain to stop the aircraft if he lost his screens, and I would say something to that effect if I lost mine.
Blue sky weather, GO would probably be the decision, but there would be serious discussion about stopping the flight immediately.
What if the screens shut off as a result of a short circuit and impending electrical fire ?
