The last passenger 772 was delivered 15 years ago (AF on ordered 2 cargo 772 after 2002). NEV4 was introduced in early 2010s, so no new deliveries with NEV4. The 772s with NEV4 are only retrofitted (there are also NEV2 and NEV3).
But I would not say that the recent NEV4 have a large screen, it is quite small. Maybe a bit larger than NEV2 or NEV3, but still small for business class.
