What are we doing for TVs these days software wise?
I have been using kodi but it just so limited and clunky. Android TV is better but that is a major challenge since Android TV is very tied to Google with not much existing outside of Google.
What I am looking for is a device that can work with mostly Jellyfin. I don't use any streaming services. It would need to work flawlessly with a remote and I am looking for something that maintains itself mostly.
Cheapest TV you can find that has the specs that you are interested in combined with a $50 pawn shop laptop and an inexpensive wireless keyboard and mouse.
Linux is optional but highly encouraged.
Connect that to a USB dac which is then piped into an amplifier for 2.0 sound.
I could probably rig up a subwoofer for a little extra oomph but none of the amplifiers I found at the thrift store have a way to turn off a powered amp or power an unpowered one.
A 4B is kind of the minimum for newer Librelec versions. Still cheap and fanless with a good heat sink case. I've learned recently about CEC and it works on my old Panasonic with Viera but I keep a little Bluetooth keyboard around too.
Another option would be one of the t95 Android boxes. There are some really great tutorials on how to replace their stock firmware with a Linux and get all of the activity and availability that you would typically need as a media box out of them for just you know $25 and 3 to 8 hours of your time depending on how tech savvy you are and what your luck of the draw is.
