Thank you Fritsch for your answers

I managed to run the 3840x2160x50Hz mode. I found your answer in the topic about intel NUC on the LibreELEC forum

https://forum.libreelec.tv/thread/9179-i.../?pageNo=4

There you provided the xorg.conf file that worked for me like a dream. In addition to the 3840x2160x50h resolution of Live TV, it started to work super smoothly, and the Kodi menu itself works super smoothly. Previously, it worked much slower.
I think you should consider adding this file to the new Milhouse builds.

In this resolution, the bar about which I wrote does not exist, so the matter is solved. I have another problem, probably the last one that has been tiring me for a long time, but he is no longer associated with judder.

The problem is with sound sync with my AVR. Often when watching channels on Live TV, LibreELEC loses synchronization with my AVR. Sometimes also when watching movies from my NAS server, I will give pause and I will turn it on again.

In the KODI settings, I have selected the option "Keep audio device alive: always" but it loses synchronization anyway.

I noticed at 10:51 when switching channels losing synchronization
I noticed at 11:23 while watching Live TV losing sync.

Do you have any idea?

- Enable Sync Playback to Display for the sync problem.
- the xorg.conf workarounds broken TVs / AVRs that can only cope with the high bandwidth on paper and therefore it's not standard. There is a reason btw. you don't get the 3840 x 2160 with 50 Hz out of the box ....

Are you suggesting I have a damaged TV? That's why I have no choice in KODI resolution 3840x2160x50Hz?
I do not understand why I have a choice of 3840x2160x60Hz resolution and theoretically weaker 3840x2160x50Hz I can not choose anymore?
TV is still under warranty so I can try to file a complaint.

I have one more problem since I bought a new Samsung UE55KS7000 TV. The problem occurs on some channels and on some programs. The image jerks.
I recorded such a program for a HTPC disc and recorded it as a tug on TV.
Could you watch these videos and check?
I noticed that when the advertisements are broadcast, everything works perfectly smoothly.
These are the films:

I have the impression that the ads have a larger number of FPS and therefore they go smoothly
