I dunno if TV is dead per se as we all enjoy watching shows/movies. Not really interested in gimmicks - we only have 4K as all new TV’s are 4K & we only got it because our previous TV failed & they can no longer be repaired.

All i want is a good quality dumb screen. You can stick all your smart features where the sun dont shine, I’ll handle everything via a separate box that I control thank you. I’ll not be at the mercy of your shitty EULA, you won’t monitor my viewing habits or force ads into the UI or remove your dogshit apps without warning. Our TV has never been online, HTPC with a couple of USB TV tuners, uBlock Origin, an interface of my choosing, remote control & lots of storage handles everything. Still perfectly happy watching SD stuff, the only 4K we watch is YouTube.
