My parents are getting a new tv, and are asking for recommendation. I think all I can influence is the brand/model (not realistic to propose rpi and more complex systems). I instinctively avoid google/android and lean towards anything else open source, so probably LG WebOS… But I had bad luck searching for more detailed comparisons. Maybe you have experience or opinions?
LG WebOS doesn’t have good support for things like Jellyfin. If you want to ever build a library of media and let them have easy access to it, then WebOS is gonna suck, so will Samsung’s Tizen. But all the Android TVs have access.
Don’t know if you’re interested in that kind of thing, but figured I’d share it in case it was a factor.
The only other alternative is a commercial display.
