tvservice -l does show both displays. Not sure how to make both work.
anyone?
what device you have? and do you like to have 2 screen on a desktop environment ?
PI4. Well, for testing its dual LCD monitors, but in my environment it can be a 7" LCD or a 5" round LCD.
is their some kind of x application you like to run on both screen or just some console?
Custom X application

not sure if that entry would go in /boot/dietpi.txt or not
Wish I could help more
such things would need to go into config.txt.
ok, I believe that link worked. I’ve been messing around w/config.txt so I need to find out what actually fixed it. LOL
ok would be nice if you could share the “real” solution. Might be helpful for others
