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?
I would be careful of anything ‘smart’.
You don’t have to get a smart tv at all. TVs do not need to be smart. If you search ‘business monitor’, you will find large quality displays such as used for corporate signage. The one issue is they often have only a few inputs, but that is easily addressed and worth it to avoid the completely unnecessary hassle of a TV too smart for your own good.
My two cents
My advice is never use a smart tv of any kind.
Use a third party device like an apple tv or roku, hell even a bluray player with apps on it.
Then get what ever TV you like and never let it see the internet.
I personally like Visio, but any mid grade display is fine.
Everything is really bad. But sadly it is nearly impossible to buy a normal TV these days. Just buy any SmartTV, and get yourself a MiniPC with the Linux Distro of your liking.
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.
