I didn't bring up 1080p/120fps on a PC because I didn't think many 120Hz TVs can actually do it. I have a Sharp 60" 120Hz 1080p and it can't. Stutter free 23.97 playback tho, so I don't know if I want to do a 60Hz 4k TV at this point. Unfortunately I can't afford a 65" 120Hz 4k TV and that's what I really want.
In the end if the TCL 65" P handles 23.97 output good enough I just might go with it anyways...
There's no reason to be skeptical, go look at info on Rtings for yourself. On the TVs that support it, 60hz isn't a locked refresh rate, it's just the max rated refresh rate, that's why 24hz source material can still be displayed judder-free. Just like a 144hz computer monitor doesn't have
to run at 144hz all the time, you can set that in your computer's display settings and run it at a lower refresh rate like 120, or 90 or 60, whatever. Now, as for TVs that can actually remove
judder from a 60p/60i source that is playing 24hz content (set-top box etc.), what happens there is it can analyze the 60p/60i signal as it receives it, and it sees where the frames are being duplicated unevenly (that's what judder is, some frames get duplicated more than other frames and thus you see them on-screen for a fraction of a second longer, making the "judder"), and removes those extra duplicate frames, thus creating a smooth image with all frames being displayed the same amount of time on-screen. Like I said, this feature is only available on higher end TVs usually, presumably because it requires extra processing power and special algorithms, but it does exist and is possible. You just need to research the TV you buy, rather than simply hoping that it'll do what you hope for.
Off the top of my head, the Vizio P series (2016), Sony 2017 lineup, and LG 2017 OLED lineup are all capable of [email protected]
I know others support it too but I can't remember without looking it up. I know the Samsung KS8000 is not
a true 120hz panel which is really irritating when its direct competition (Sony, Vizio) is all 120hz. This is a specific spec that Rtings tests for on all the TVs they review, btw.
Is your Sharp TV a "true" 120hz panel or does it just have a motion interpolation setting up to 120hz? Cause that's not the same thing.
