I don't even understand the pitch? you have the disc playing, in your hands, your ownership, no buffering, no subscription required. and they're saying....hey do you want a worse experience?
You probably want commercial displays. They'll cost a bit more, but they're also designed to run 24/7 (think the screens they use in menus, signs, etc) so they could probably last forever as a TV.
Do you have a suggestion for one with HDR or that runs a proper refresh rate and response time. There are a few good options for NEC but they're about 15 grand.
All my smart TVs have existed without wifi or connections to the net themselves, only the devices that connect (Nintendo, Playstation, Roku, etc) . It's easy from that perspective, all depends on what you want and need.
