I was having some issues after upgrading the PM Server, most of which got fixed once I found this thread and upgraded my Home Theatre. I am still having audio sync issues with some files. I tried these settings:
Playback -> Advanced video -> Adjust display refresh rate: On start / stop
Playback -> Advanced video -> Sync playback to display: Unchecked
System -> Advanced -> Resolution: 1920x1080p (TV should switch to 4K when playing a 4K video)
System -> Advanced -> Refresh rate: 60.00
System -> Advanced -> Vertical blank sync: Let driver choose
Except that even after switching the theme back to default I still don't have a refresh rate in the advanced menu, and for vertical sync my choices are: Always enabled, Enabled during video playback, and disabled.
Any help would be appreciated..
