Hi All,
A plea for help. I have so nearly got this working. Any pointer for what I should try next would be very greatfully received.
I have been following the wonderfully well explained instructions here…
All goes well until the final step where I get the message “vc_dispmanx_display_open failed! Make sure to have hdmi_force_hotplug=1 setting in /boot/config.txt”
And I do have.
Thanks!
