This 3:2 causes artifacts, such as blurriness or choppy frames during fast motion. So my massive blu ray collection and DVD collection would look like crap on a 60 hz TV. On 120 HZ it can scale down to 24 fps since 24 can go into 120.
With this 240 natural motion it's looking like TCL has upgraded their American products to 120 HZ displays at last. (Most of the time what they advertise is double the native rate so with their ****ty 120 HZ CMI BS) On games and streaming you wouldn't notice since both will output at 60 FPS, but any physical media will look choppy and unnatural.
A 60 hz TV can do 24fps without judder if it can drop down to 48 hz.
