Honest question how do we stream from Netflix, HBO Max, Apple TV, etc without connecting to the internet? Also, most of those stream require a recognized device to stream over 1080p. So basically, if you get a new TV wouldn’t you be operating it as a old TV on those terms? The alternative that I see is keeping all that you want to watch at 4k in Jellyfin or Emby (don’t use Plex it is just pushing ads) but you will need to maintain a library.
Yeah, I get it. Disconnecting the TV is a must, and luckily I never even connected mine for many years. The thing is that I’m not sure that we can trust in the licensed devices either. Chromecast, Fire TV, Nvidia, etc… All of them have trackers as well. A PC or a Pi would have the limitation of streaming at maximum 1080p resolution for some streamers providers such as Netflix. It is quite a challenge!
