Have Banana PI M2 Berry here, installed
When power up the PI, the monitor don't wake up.
I have to unplug HDMI and re-plug the HDMI, so the monitor wakes up.
Also after reboot, monitor stays off.
Have tried set the "hdmi_safe=1" in config.txt but didn't help.
Also in the uEnv.txt in
And how can I disable the energy management, that switches off the monitor after a time?
