LibreELEC 10.0 B1 on Raspi 4: No Signal when enabling 4kp60

    Hello,

    while testing the 10.0 B1 I'm facing an issue when enabling 4kp60 output.

    Everything is fine when using 4k 30Hz, after enabling 60Hz and rebooting POST screen is shown then the screen turns black and, after some seconds, I'm getting the "no signal" splash from my TV.

    I'm running

    LibreELEC 10.0 B1 (fresh install)

    Raspberry 4B 4GB

    Samsung UE50NU7479 TV.

    When using the identical hardware but LibreELEC 9.2.6 everything works perfect.

    Does anybody has a clue if this is a general issue or something specify to my hardware?

    Is there a solution for this?

    You can find the respective log files linked below

    Thanks a lot for your help!

    Don't add hdmi_enable_4kp60=1 to config.txt yet - 4kp60 isn't implemented in the video driver yet and if you add that to config.txt you get the issues you described.

    so long,

    Hias
