Hi Guys
Have a Raspberry Pi 4 with 8gb ram and 2 HDMI ports, and i instaled Volumio , but only One port HDMI works, Can you Help me
i will have a 7" display, and i will on another HDMI port to run Smart TV LG, but how i say, only one port on Raspberry Pi works, did i must go in Raspberry Pi set up to activate 2 HDMI or Volumio can run only one display ???

Connect to Volumio via SSH and try adding

max_framebuffers=2

to “/boot/userconfig.txt” and reboot.
