[RPi4] Sometimes black screen when starting LE12

    Sometimes, when booting up LE12.2.1 on an RPI4B, I get a black screen with in the left upper corner a line of text that says something like Libreelec 12.2.1.
    At the same time I hear some notifications from kodi and when I operate the remote control I hear the typical sounds from the Kodi interface.
    After disconnecting and connecting the power, everything works ok.
    Any ideas?

    The Linux end of things is probably trying to use a 4K mode the TV doesn't like. Append video=HDMI-A-1:1920x1080M@60D to the line of boot params in cmdline.txt on the SD card and reboot. That forces the intial DRM state to 1080@60 which should avoid the issue, and you want to be using 1080p for the Kodi desktop anyway (unless you want a slow GUI experience).
