I tried your suggestion, unfortunately no change. Could it be the receiver? It is an older Yamaha RX-V467.
Tried also to create an EDID under 10.0.1 and then update to 10.0.2. Didn't work either....

Update:

Connected the RPi4 directly to the Sony TV KD55A1 with no receiver in between and updated to 10.0.2. Same error. The Sony is on the latest Android. The HDMI cable is the original Raspberry one.

Also updated the EEPROM under 10.0.2:

Code

$ rpi-eeprom-update -a
BOOTLOADER: up to date
   CURRENT: Tue Jan 25 14:30:41 UTC 2022 (1643121041)
    LATEST: Thu Apr 29 16:11:25 UTC 2021 (1619712685)
   RELEASE: default (/usr/lib/kernel-overlays/base/lib/firmware/raspberrypi/bootloader/default)
            Use raspi-config to change the release.

Display More

Only way I got it to display was with in /flash/config.txt but that defeats the purpose:

dtoverlay=vc4-fkms-v3d

so it seems vc4-kms-v3d.dtbo related which causes:

There seem to be some fixes coming in 5.13.0-1010.12 and/or 5.15.0-1002.2:

Bug #1946368 “HDMI output freezes under current/proposed impish ...” : Bugs : linux-raspi package : Ubuntu

[Impact] The UI of Impish desktop for raspi occasionally freezes which can be triggered by playing videos and moving windows around. Seems to happen more…

cubalibre looks like some kind of DRM problem; the board doesn't see any valid modes on the HDMI connection - none are listed in modetest and the kodi.log shows DRM errors. See if adding "video=HDMI-A-1:1920x1080M@60" to params in cmdline.txt works?

Hi, great work so far.

I updated manually from 10.0.1 to 10.0.2 on an RPi4 4GB. RPi4 -> HDMI 0 -> older Yamaha Receiver (max 1080p) -> Sony KD-55A1 4K Monitor on HDM3/ARC.

Can't get the video to work on 10.0.2. Installs fine and I can still ssh.

Here are the details:

LibreElec 10.0.1

Code

LibreElec 10.0.2

Code

Any ideas why video doesn't work?
