Raspi 4 + LE 10.0.2: no video on HDMI0

tecc · June 13, 2022 at 10:19 PM

So, I've added hdmi_safe=1 to the config.txt and rebooted, switched HDMI ports and then configured Kodi via the GUI. When I rebooted manually, I only saw the initial boot phase on 640x480 up to the multi-coloured square but then then my TV's screen stays dark. The TV is capable of 4K on Kodi which works fine with my Odroid and CoreELEC using the same HDMI ports but I would rather use the Raspi 4 instead. What can I do to get video? Thx!

Try an HDMI cable, which is known to work with 4K. When buying a new one, it should have HDMI 2.0 or 2.1 standard (a.k.a. 4K).

I have only one cable I can use for the Raspi 4 due to the mirco connector on one side. This is the cable that actually worked that one time where Kodi automatically set the GUI size to 4K. So I doubt it's the cable. I just don't get why this setting appears to be lost on reboot or whatever the reason might be that after reboot I can't get a picture like I got before. Anything else I can try?

That probably creates a setup error. Login by SSH, delete .kodi/userdata/guisettings.xml, reboot, and configure again.

Another approach: Put the line dtoverlay=vc4-fkms-v3d,cma-512 into /flash/distroconfig.txt.

(replacement for dtoverlay=vc4-kms-v3d,cma-512)
