I have several orange pi 5B running Armbian Bookworm Cinnamon doing various task and they are working quite well.  when i want to check up on a system that was booted without a monitor connected at boot time i get no video output on the HDMI.  when reboot with the HDMI connected the HDMI outputs video just fine.     Are there any settings i can change so the HDMI will output video if a HDMI monitor is connected it boots with no monitor connected
