A:AnswerMy opinion: No
Generally, TV / Monitor combined use doesn't exceed 32"
This is a 55" screen.
If it is mounted on a wall in a shared room (break room or meeting room) then it may be suitable.
A:AnswerYes and no, it’s not directly on the side. The input locations are inset/recessed on the back side but about 12 inches from the edge. If you are looking at the back directly it would be on the left
A:AnswerJust regular Hulu, I see nothing for Live. But Samsung says this about TVs with Hulu apps on them:
"If you have a Hulu supported LG, Samsung or Roku device, you’ll be able to subscribe to Hulu with Live TV and gain access to live and on-demand programming from over 50 top channels."
I haven't tried to sign up, so I can't advise further. Hope this helps.
