Ask HN: Which TV do you recommend for privacy?

I haven't owned a TV in years and want one that respects my privacy. I'm looking for a 60" to 80" 4K display with at least 60Hz, and I'm willing to pay a premium. I've heard Apple TV is a better alternative to most smart TV native apps, and I want the TV to do nothing but act as a display for Apple TV—so I'm curious which TVs pair best with it for privacy and what success others have had.
