I have volumio running on a Raspberry 4 B. The 1st HDMI-output is used as audio output. Is it possible to change the video output of the touch display plugin to the 2nd HDMI-output?
Open “/boot/userconfig.txt” with nano (editor):
sudo nano /boot/userconfig.txt
Close and save the file by typing Ctrl+x, y and Enter.
Disadvantage of this solution: The rotation option of the Touch Display has no effect.
Thanks. It works.
