Mini S-12 Pro Second Screen

terryg

I've build my new miniPC S12 Pro using the latest Debian Bookworm, kernel version 6.1.0-13.

I'm unable to configure and use a second HDMI port. I've used a variety of screens and HDMI cables.  Each screen works properly when it is the only one attached and will work on either of the HDMI ports.  When a second screen is connected then nothing is displayed on that screen.

Linux says that I only have one display.  How do I use two screens?
