I mean frame dropping but due to frames not lining up with the display refresh rate. It is due to the frame durations of the video and display not aligning perfectly given them being different and both’s having low frame rates. A 24 fps movie’s frame times will not perfectly align with an HDMI 1.4 30 Hz display’s frame times, resulting in slightly jerky playback. Though there is an option in Kodi to adjust the display refresh rate to match the source video, most media players do not have this functionality and will suffer from this jerkiness with an HDMI 1.4 connection to a 4K display. If you use just a 1080P display, none of this applies since the refresh rate is 60 Hz or higher via an HDMI 1.4 connection.What do you mean frame dropping? What refresh rate does Kodi output at?
