Known limitation/bug, see first post. Can be worked around by configuring kodi to play a file on startup. Nobody really cares, because even the first video is played fine.
Libreelec/Kodi does everything right. If it offers resolutions/refresh rates that your display cannot show, you might be left with a black screen and no way to go back!
Workaround for your buggy hdmi device: The linux kernel reads the display information from hdmi and provides it to kodi through a sys node. You can replace this node with a file, as described here: thread-1564-post-23856.html
Be advised that this should be done only if you understand basic command line use and have some idea about how linux works.
Thank you very much. Everything is working now.
Only "problem" remaining is that after reboot there seems to be no internet/network connection (wired) so Kodi throws some errors.
5 seconds later it finds internet and I can click the error message away.
No idea if this is a problem of my box? M8S II S905X.
Is there a way to delay loading add ons.
So it waits for 5 seconds, finds the internet and only then loads the adding with no errors.
Is this possible?
