@baronessloveandlight @Sophistifunk This is why I still have an old plasma TV. It looks great, it has no 'smarts' and plenty of inputs. Yes it's bulky and a bit power hungry, but it works.
That said, I've gathered some dud commercial advertising displays and large monitors from jobs over the years and repaired them myself.
I've never been overly happy with the sound from a display. I've always had a separate amp or modified the speakers to suit.
