a) use "Adjust display refresh rate"
in this case, the TV will switch to the FPS of the movie, which ensures not only smooth playback, but also allows for audio passthrough. So any AC3, DTS, TrueHD stream etc can be passed untouched to your AVR. This is only possible, because the rendering clock of video and audio can stay in sync since video doesn't have to be adjusted to match your TVs refresh rate (like frame blending/duplicating, ...)
b) use "Sync playback to display"
in this case, the TV will stay at your defined 60Hz and the video will also be smooth, since frame blending/duplication will be done (which is what Netflix and Amazon do). But in this case, audio passthrough will automatically be disabled, since it's not possible to properly "adjust" the timing of the audio packages to match again with the video (they would have to be "duplicated" which will sound terrible). We could ofc still do passthrough, but audio and video would get out of sync. So in order for you to still have surround sound, you need to adjust your audio settings accordingly (set number of speakers to what your AVR supports, like 5.1, 7,1 etc). With this mode, you WON'T get any Dolby Atmos, since, at least to my knowledge, it requires passthrough (the meta-data used by Atmos can't be sent via the decoded PCM audio stream)
Thanks for that explanations but this seems to be "only" theory. In fact, in pratic, also if I enable "Sync playback to display" (and disable "Adjust display refresh rate") the 24fps videos on a 60Hz output are NOT SMOOTH.
So, it seems that if the fps of the movie/video is for example 24 and the refresh rate is 60Hz there is not a settings combination to see smooth apart from enabling "Adjust display refresh rate"...
I repeat, in my case, it does not depend on the TV: I can see smooth movies with Netflix, with Amazon Prime Video also if the HDMI output is at 60Hz.
I can see smooth also with PLEX (also in audio passtrought) and VLC (also in audio passtrought) with exactly the same movie at 24fps and HDMI output at 60Hz with exactly the same setup.
The problem is only with Kodi.
To see smooth with Kodi the only way is to "Adjust display refresh rate".
So my question is always the same: WHY with the same TV and same HDMI output resolution and refresh rate (60Hz) I can see smooth 24fps movies with PLEX or VLC and NOT see smooth with the same 24fps movie played with Kodi?
With Kodi 17.6 there was not that problem (always with the same setup).
I do not want to be petulant but there is still a problem on Kodi 18 with this.
@wrxtasy if I understood correctly from your answer, you confirm what I noticed beacuse you have the same problem.
I hope in an investigation. Thanks!
