^^Thanks to all who posted above.
It's a large family room, gonna have tots running around destroying things. Viewing Distance Calculator says that we can take all the length width up to just over 85". We'll watch movies but we aren't "serious" so not planning on surround sound, running wires through the walls, etc.
My understanding is that modern TVs have crappy built-in speakers, hence the supposed need for a sound bar (and I can see a subwoofer, too). I assume that I'd need a receiver to run speakers external to the TV? If so, about Yamaha...
I've had a Yamaha receiver running almost daily going on 26 years now, and I love it. On the other hand, a friend of mine has gone through 3 Yamaha receivers in the last 7 years or so, and that has me concerned about the reliability of modern Yamahas. Should I be concerned?
I guess I can go with 4K, but I don't even know how to find content in 4K. Do I want a "smart tv?" I have streaming boxes already, but I assume "smart tvs" are the standard. What to look for, and avoid? I just sure as hell don't want a TV that will watch me (camera) and listen in on my conversations (e.g. Alexa, Google Home, etc. capability).
I'm in DFW, btw.
