I currently have Plex and Radarr. I only ever got 1080p content because that’s all my tv would do. Finally getting a nice new tv and would like to get a few 4K hdr movies to watch. Should I be looking for Bluray2160, Remux, or disk and what will Plex play?
Ok, the built in sammy app is OK, but the files have to be the right format, so you will hit a problem file occasionally.
I’d use the AppleTV 4K as it has better format handling and supports higher bitrates.
Make sure your local network is up to scratch too, doesn’t matter how fast your internet is, if your TV is on wifi it might not be enough for Plex 4K streaming smoothly, and ethernet on most TVs is 100mbit, which can also be a problem for high bitrate 4K.
Watch out with the Apple TV, stay far from Dolby vision as the playback doesn’t support all profiles (really not a lot of profiles)
