Kodi 4k on Raspberry 4

    Hello everyone,

    I am new to this forum so appologies if I might ask questions that have been answered already.

    If that is the case all links to similar issues will be appreciated.

    Now my problem description.

    I am running LibreELEC-RPi4.arm-10.0.3.img on a Raspberry 4 connected to an Onkyo Receiver which uses a Sony Projector for display.

    The Onkyo with the Sony can playback 4k Videos with 60 Hz and HDR10 as my also connected Apple TV proves.

    Kodi runs well with 1080 p. When I try to show 4k Videos the picture is only showing in the upper left corner on 1/4 of the screen.

    I changed the config.txt already adding the hdmi_enable_4kp60=1 part but no change.

    Also if I change the Mediacenter GUI to 4k I have the same result.

    I tried to change several settings, added a new cable to the Onkyo -- no change.

    Any hints and ideas welcome. Would like to get this running asap.

    Thank you in advance for help and support!! :) :)

    Normally GUI only appearing in a quarter of display is some mixup in guisettings.xml.

    Can you try (ssh in):

    Code
    systemctl stop kodi
mv /storage/.kodi /storage/.kodi_back
systemctl start kodi

    Do you now have kodi working with full screen 4k display?

    If it doesn't help you can move the .kodi directory back.
