edit /boot/config.txt:

  • Find hdmi_force_hotplug=1 and change to
    hdmi_force_hotplug=0

and

edit /boot/recalbox-user-config.txt:

sdtv_mode=2
hdmi_force_hotplug=0
hdmi_ignore_hotplug=1

Sorry, I don't have Rpi4 and I can't test it, but if the other users just edited these parameters and it worked, the most logical thing is for you to test it by doing exactly the same thing and only if it doesn't work ask for help...
You should leave all other parameters as they were before and edit exactly what other users suggested...
