My direct experience is somewhat out of date, but from an engineering perspective the unit I have is much simpler than any TV, since it lacks a tuner or any fancy video scaling capability, and has no audio capability of any kind (that was a feature to me, since I use an A/V Receiver for sound). I think in general screens meant for signage are probably brighter than most TVs/monitors, but depending on the room that could be a useful feature as well.
