If your going to stay connected to your TV then try two channel, and disable DTS, DTS-HD, and TrueHD. It may be possible that the TV does not allow for passthrough of bitstream at all or requires you to manually set the input as bitstream to pass that though the TV. AC3 transcode can sometimes be a bit funny so you can try disabling that as well.
That being said I agree 100% with ActionA that it makes a lot more sense to plug the Vero into the AVR and then use your current settings except with AC3 transcoding disabled as it would serve no purpose when connected to a modern AVR.
You should also tweak your video so it will actually output 4k
Summary
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.
FYI, setting the recent items to such a high number normally has a negative impact on the responsiveness of the GUI.
