I miss the silver plastic era of AV equipment. Like in the mid-to-late 2000s when every TV was made of silver plastic, and it had that set of composite jacks under a flap on the front, so you could temporarily plug things in, like when your buddy brought his PS2 over. There was a button near the channel and volume buttons that switched between inputs, and it didn't take a digital act of congress to figure out which setting would get it to display on the TV.
Now everything is a black rectangle with bullshit software and almost two HDMI ports in the back, except one has the sound bar plugged into it, and the labels are stamped into the black plastic and not painted on, and with the shadows behind the television you can't read them. And it doesn't work when plugged in anyway. Its easier to just not have friends so that you never have to plug other electronics in. Stare at your phones alone.
So just don’t use the built in software. I don’t have any of my TVs connected to the internet or use their built in OS. I have a couple of Apple TVs plugged in and run everything off that. Never even set the things up beyond plugging them in and switching to HDMI 1.
There’s also the Chromecast TV if you use Android.
If you use a separate smart tv device like those, then the only thing you need to care about on the TV itself is resolution, refresh, and number of ports. Or if you want to spend a chunk of change then you can look into things like OLED. But the separate devices make the TV OS irrelevant.
My personal TV is a Samsung commercial display unit; it isn't Roku or Tizen or whatever else. It's still very much a computer though, it still has a network port and keeps pestering about connecting to the internet and registering it and all that shit.
Because then you can use the ARC protocol to minimize the number of remotes. The TV will pass volume controls through the HDMI port and the sound bar will adjust volume.
