RPi4 works with my 1080p Sony but fails with my 2160p LG.

  • I am attempting to update my LibreELEC platforms from RPi3 to RPi4 in the understanding that HVEC support will be better and that I can play UHD content.

    While the RPi4 starts up fine and presents the KODI menu, on my Sony 1280p TV, it fails on my 2160p LG.

    The symptoms are that the rainbow splash screen displays, followed by the LibreELEC splash screen with boot messages in the top left corner. However, when I would expect to see the KODI splash screen, the display goes black and, after a few seconds, the TV reports 'No signal'.

    Is there a way to get LibreELEC working on my UHD TV?
