It’s a terrible effect, and people who don’t spend much time in their TV’s setup may not know or think to turn it off - or they delude themselves into thinking they like the effect.

If you’re watching a tv and the frame rate hitches all over the place every few seconds then one of these stupid fucking settings is on.

The shit wouldn’t be so fucking awful if it could actually maintain a stable frame rate but it can’t. None of them can.
