I recently got a new 4k TV. Previous one was FHD.
Besides that, no changes on my system/setup.
Now I have the issue that Live TV is stuttering on 4k screen. It’s only subtle, but impossible to oversee.
Channel (SD format, HD format) doesn’t matter.
I’m sure I must have some settings wrong, not sure which ones though. Any ideas what I can try?
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>System>Display>Resolution> 1920x1080p
Settings>System>Display>Whitelist> (empty) *
Settings>Player>Videos>Adjust display refresh rate> On start/stop
Some televisions may also need, or benefit from, the following being set…
System>Display>Force 4:2:2 colour subsampling> (enable)
With the above settings your UI will be output in Full HD and your 4K content will be output in 4K. *Information regarding the whitelist can be found here. If you have any doubt, feel free to upload some logs so we can verify that your settings are indeed correct.

Settings → Live TV → Fallback FrameRate
Use 50 Hz if you’re in a PAL region and 59.94 Hz for NTSC.
