Roku’s Ultimatum: Surrender Jury Trial Rights or Lose Access to Your TVs
(programming.dev)
This is a most excellent place for technology news and articles.
The thing is 5 years old so that's hardly surprising. I just googled 65 inch monitor and this was the first hit.
Just checked Geizhals and apparently there's none currently, the largest is the HP Omen X, 64.5". Close enough though I'd say. There's 55 monitors 46" and higher but only 7 52" and higher.
At that size I'm obliged to ask if you don't want a projector instead.
