Raspberry 4 and 4k issues

  • Hi,

    I'm having issues when I try to use 4k with my rpi4 (LibreELEC-RPi4.arm-9.80-nightly-20201127), Onkyo AVR and 4K TV.

    I can't choose a resolution above 1920x1080.... Even with hdmi_enable4kp60=1.

    Kodi return the following info :

    With the following EDID

    If I change the driver from vc4-kms-v3d-pi4 to vc4-fkms-v3d, Kodi is in 4k with the following log :

    But in that case, I have no audio device in ALSA ...

    Any idea to solve this ?

    Thank you,

  • Correct. FKMS was basically a stop-gap to transition to standard linux drivers, all development is now focussed on KMS. 10-bit output, 4k etc will be added at some point but we don't have any ETA.

    so long,

    Hias
