Dont know exactly for your box but I'll thing they run same basics.
Do you have kind of two different menu that handle settings? I do, one is very similar to regular android settings and the other feel somewhat more box/tv settings, anyhow in this second settings menu there is a variety of hdmi...
Look for the setting Adaptive Frame Rate (or Auto Framerate Refresh) android also have a setring for hdmi (self-)adaptation that will enable switch 50/60hz.
Much dependant on your display and it's features aswell.
Hope I clarified something at least :)
Also like it quite alot and will probably keep it as main player. Some issues and notes following:
Refetch of full list/epg if you switch user.
Automatic start of first channel in each group makes the navigation slow and choppy.
Lack of AFR switching.
Navigating in EPG-view is awkward and I tend...
To avoid transcoding of all channels through place engine it's totally dependant on what avail at the device used as player
The plugin you look for is iptv.bundle https://forums.plex.tv/t/rel-iptv-bundle-plug-in-that-plays-iptv-streams-from-a-m3u-playlist/44559
Estiptv is back and i got what I've paid for.
Maybe a glitch or human error either way it shows how fragile the system Is.
I'll surely not buy in such bulk again.
Also, my new service that i had to get elsewhere provides catchup on most channels.
