Subtitles positioning with Kodi on the Dune?

[Hann]

Kodi seems to be functioning well for video playback for me. There is no brightness bumping for me either in HDR and therefore it seems to beat the internal player on video quality for me.

However, when in my projector I have zoomed the picture to fill up the 2.35:1 screen, the subtitles with Kodi are displayed under the video. How could I raise the subtitles to be displayed on top the video picture? I read about making settings in Kodi system --> video calibration, but that did not seem to help. Also there was information about pressing ctrl and I think arrow keys to position the subtitling, but I believe that only relates to using Kodi as a playback device on a computer. Is there a shortcut on how to raise subtitles with Dune or is it not possible with the Dune at all? The presents in the Kodi do not seem to help (= above video, below video, bottom of the video etc. With "Bottom of the video" the subtitles are on the black bars visible under the picture)

Thanks for any help - I would really want to use Kodi as the playback software, but if I cannot use the subtitles properly I best revert to the internal player with the brightness bumping...

It seems that this problem is related to me not being able to change the resolution from Kodi system settings nowhere from 1920x1080. I am sure I could determine the location of the subtitles if I managed to change it into 3840x2160p, which my projector is capable of.

For some reason I cannot change it however. Maybe some setting elsewhere in the Dune HD Pro Vision 4K Solo is prohibiting it?

Some development: if I connect an external keyboard to Dune, I can adjust the subtitles position in Kodi with ctrl+ up/down buttons. However, the Kodi does not save the position of the subtitles, so one has to do it each time, even when opening the same file.

I think I managed to solve this matter by installing separately on the Dune "kodi-19.1-Matrix-armeabi-v7a.apk". With it I can place the subtitles ok with the system settings and it also seems to remember the position of the subs.
Maybe this helps someone with the same problem, so I posted the resolution here.
