RPi 7" Touchscreen and HDMI


I just started, not a n00b on Pi, but with Screenly OSE. I installed and added an asset image 1920x1080. I have a Pi hooked up to the 7"in touch and one HDMI monitor hooked up to HDMI-0 port. I want to duplicate the image, but it spreading across both monitors. I had setup to mirror in config.txt and yet I do not know how to make Screenly show on one monitor or mirror.


This is not something that I have explored myself. Assuming you’re on the latest developer version, it should simply output on the first HDMI port (on the Pi 4). Since we just recently added support for Pi 4, we haven’t really explored more non-standardized setups yet unfortunately.
