TV motion smoothing settings are the thing no one ever asked for that will simply not go away. (And switched on by default in a shocking number of TVs...)
When I get a TV the first thing I do is turn off all the "motion enhancements" they do to the screen. (I need to see what's been filmed, not something that looks like an 80s soap opera.) And then overnight the tv updates its software and it all comes back. The screen of Sisyphus.
