Seconded. I have a NEC P461 as a secondary/movie display in my office. It's the thin bezeled NEC that you see in airports worldwide. Love it.

EDIT: as a followup, I should mention that circa 2018 there aren't really any commercial/signage displays that have 4k resolution. There are lots of "4k signage solutions" but they are all groups of quad monitors. It appears there is not yet demand (or sufficient product dev) in 2018 for 4k signage monitors. It sort of makes sense given that a departures/arrivals screen doesn't really need 4k ...
