Smart TVs are god awful, and I hate the OS on our LG TV. That said there is finally a Jellyfin app on WebOS so it has that going for it now… I’m too cheap to buy a separate box for Jellyfin and stuff for the TV, so I guess it’s good enough… but in general I wish the TV OS got out of the way a little more.

All the TVs built in stuff is not going to be the best experience. Doubly for self-hosted. A tv with android os, or a dongle inserted into a tv will do much much much better than samsung or lgs apps. An appletv too but then you're spending a lot more

The chips in these TVs are garbage and will only get worse (relative to current tech) as they age. Get a set top playback device and use exclusively that. Shield Pro is still solid, AppleTV hardware is solid too. Below those are Roku and Fire devices, they will do nearly as well.

I know android TV and Roku have jellyfin apps. But I would stay far away from LGs WebOS, and I haven't heard of Tizen.

Id honestly buy w/e tv you think looks the best quality wise, then add a media player. For ease of use Nvidia shields are fantastic and run android TV, and work wonders with steam link.

What I did was a Sony OLED which has android TV and is fast enough to use streaming apps with little annoyance. And then I bought an odroid n2+ and installed coreELEC to use Kodi to stream media locally without needing to transcode. Then use jellyfin for if I want to stream outside the house.

Sadly my setup doesn't have a solid Steam Link option, as the Sony TV isn't powerful enough and there's a delay in controller input and what you see on TV.

^ Hopefully some good ideas for you ^

Anything with AndroidTV.

I've used Samsung, LG, Roku, and none are as nice as my Chromecast.

It's hard to recommend a Google product but Google TV or chromecast with Google TV does the job it's supposed to do. App support is large and what isn't there can be installed the same way it can be on an Android phone. I can stream Playstation games to it even though Sony doesn't support it. Smart TV built in os's aren't up to par yet. At least not in the price range I'm buying my tvs.
