Hi guys
I migrated my OSMC with Kodi 19.1 from RPi3 to RPi4.
On the old one I have the following settings made in /boot/config.txt:
hdmi_ignore_cec_init=1
hdmi_edid_file=1
hdmi_force_hotplug=1
hdmi_group=1
hdmi_mode=16
So, if my projector is off and I reboot the RPi3 and afterwards power on the projector, I get a screen and everything is fine.
On the new RPi4 I dont get the same behaviour. If the projector or avr is off and I reboot the RPi4 and power on projector, I dont get output, but only “mode unsupported” by the projector. Only if I do a reboot now I get back a screen.
I played around with the config.txt a lot, but I didnt find a combination that worked
The projector is connected to HDMI0 on the RPi4. At the moment I have these settings active:
hdmi_force_hotplug=1
hdmi_drive=2
hdmi_group=1
hdmi_mode=16
hdmi_ignore_edid=1
I also tried setting the values with :0= to force it to set them on HDMI0, but no difference (it also defaults to HDMI0 if no paramter is specified though…).
So does the Pi somehow ignore my settings in the config.txt or do they just not work?!
As tvservice cmd doesnt work properly on the OSMC with Kodi 19.1 I cant provide output here.
But I created two debug logs:
- first one, https://paste.osmc.tv/osiziserep.django: with projector and avr powered on, I get normal screen
- second one, https://paste.osmc.tv/kivacomica.django: projector on, but avr off, I dont get a screen but only “mode unsupported” on the projector so I need to do a reboot
Any ideas if that is normal with the RPi4? As mentioned above, on the RPi3 I dont have a problem with that, it just works with the edid.dat I copied to /boot. I tried the same file on RPi4, just as info. I didnt create a new one as I am not sure whether tvservice works for that or not. But even with hardcoding the mode it doesnt work, so I dont think the problem is with the edid.dat
