No 2re advice like this is bad, sync playback to display should never be enabled and will be removed in the next version
I need sync playback to display because I get lipsync issues sometimes. The chain between my Vorke Z6 Plus, Yamaha TSR-7810, and LG OLED 65C6P TV has too much latency during the playback of some videos. The TV has a Game and PC mode, which reduce latency, however with those modes I lose features such as True Motion. The latency seems variable, so if I adjust the audio delay on the receiver or within Kodi, it goes out of sync again.
I'm using 18Gbps Monoprice HDMI cables end to end.
