A smart-but-disconnected TV can meet all of those functional requirements, and your nonfunctional requirements (low processing power) frankly don't matter to most people. My smart-but-disconnected TV turns on just as quickly as my PC monitors can return from sleep (a second or two); changing inputs is just as quick (input button on remote, left/right to select, okay to confirm), and the automatic input selection when a device turns on means I barely even need to endure that tiny hassle; the interface it displays is more than a dumb monitor's OSD, but not by much.
You seem to be of the opinion that it's the principle of the thing, mine is avoiding ads and bloated/slow interface. To me, keeping it disconnected avoids all of the problems of it being smart. Those "smart features" are not features to me (or most people here), but neither are they anti-features.
