I'm late to this party, but I have a confession: I was sort of wrong about smart TVs.
I've been ranting against smart TVs for years, insisting that displays should not be "smart" at all. All the while I never actually owned one, but I knew some day I would be forced to as fewer and fewer "dumb" TV's remained on the market. For me, a TV was nothing more than a very large computer monitor for all your attached devices and doo-dads, which get replaced as they go obsolete, while a good TV should last me 7-10 years. A smart TV was, in my mind, a scam toward planned obsolescence, only this time you are replacing a $500-$1000 investment every couple years rather than $50-$200. Of course, you may HAVE to buy a smart TV, but you shouldn't buy it FOR the smart features.
So last weekend I followed my own buying advice and bought a Sony Bravia x800g solely for its fantastic HDR, its reviews and its holiday price. When I got it home, I hooked up my Nvidia Shield right away because Lord knows I'm not going to use whatever crap software was inside this TV. But then I hit "power" and - what's this? An Android boot animation?
(I'm sure it's common knowledge in this sub that Sony Bravias run Android TV, but what can I say? I was a set top box snob and didn't care about smart TVs.)
To my surprise, it's not so bad. Of course, it's nowhere NEAR as snappy as my 2015 Shield, but it's alright considering I would have bought it for the price I paid without any smart tech whatsoever. Android TV was like a freebie, so I can't complain. Sony loaded the app drawer with bloatware, of course, but I've removed them from the home screen so I don't think of them much.
One big surprise is that this TV actually does some things BETTER. Particularly, turning on or waking the TV with the remote or with Google Home is much faster than my Shield, mainly because the latter had to do so by communicating with my Receiver and TV through HDMI-CEC. The Shield talking to my old Onkyo receiver sometimes took as long as a minute.
Also, the Bravia seems to handle my old legacy HDHomeRun tuner's MPEG2 streams over WiFi without a glitch. I have no idea why. My Shield had to receive MPEG2 over a hardwired Ethernet connection. My only theory is that Sony focused a lot on limiting packet loss over WiFi to make it work flawlessly with external tuners, but I can only guess.
The Shield is now moved to the bedroom, still serving as my Plex library server while retiring my old Nexus Player that served me well for many years. I'm sure that once my Bravia stops receiving security updates I can just turn off its WiFi and hook up the latest Shield.
So I guess the moral is that every piece of tech has it's place for someone. I wont give up on the trusty external Android TV boxes, but "smart" TVs aren't nearly as "dumb" (lame pun intended) as I thought. For now, this set up works.
The only shitty part about most smart TVs is that they have a 10/100mb nic. If you're far away from a router with poor wifi performance but have a Ethernet drop you're limited. My Sony Bravia could not run any 4k hdr on the Sony nic/wifi so I got a shield.
