I noticed that when started playing content that was available in both 1080p and 2160p, player always choose to play the 1080p stream by default on my NVidia SHIELD TV Pro player.
Is this for a movie? I feel like there’s info missing. If it’s a movie and you’ve got multiple versions working properly you should be able to “Play Version” try selecting the 4K one and see what happens.
I’ve got mine set up like this, no problem differentiating between 1080p and 4K on applicable devices.
If I play this through the web, it’ll be 1080p, if I play on my Shield I get the 4K.
This is for both movies and TV Shows.
In my case I have two versions for each file, one 1080p and one 2160p.
Play version is available and works correctly, so selecting 2160p will play the correct content.
I’m just trying to understand why it doesn’t play 2160p media by dedault and I think it is due to X-Plex-Device-Screen-Resolution => 1920x1080
If it works “correctly” when you select 4K under play version, have you checked the dashboard or Tautulli or anything to ensure that it’s actually playing 4K and not transcoding?
Anyone from Plex is going to ask for debug logs from the server at least, maybe the client as well. It still sounds like a settings issue somewhere to me though. As I said, I have the 2019 Shield Pro as well and it chooses properly for me.
