neither Factory Reset nor a new installation did help my Issue:
About every 120 seconds the picture freezes for 1/4 seconds while Audio is still playing.
This happens with SDR and HDR Content, with mkv and iso Files, no matter if Audio is set to “Passthrough” oder not.
We recommend people with 4K TV’s set their user interface (UI) to 1080p. Kodi’s UI is not optimized for 4K yet and this can put unnecessary demands on your device and can lead to a suboptimal picture quality, as well as potentially cause other issues.
The settings we recommend are as follows…
Settings>Player>Videos>Adjust display refresh rate> On start/stop
Some televisions may also need, or benefit from, the following being set…
With the above settings your UI will be output in Full HD and your 4K content will be output in 4K. If you have any doubt, feel free to upload some logs so we can verify that your settings are indeed correct.
