Updated MMM and MMM-PIR, Monitor turns on and stays black
I really like this Project, and after having it on my Desk for a while reminding me to do some Updates (Magic Mirror itself and the PIR-Module), unfortunately switching to PM2 for autostart in the same Process, I’m Stuck on the problem, that the Monitor starts getting a Signal, once the motion is detected, but the only thing I’m able to see is de working Backlight.
If i do a reboot, evrything is working, as long as the Monitor stays on. After being switched off an on by the PIR-Module, it stays black except the Backlight comming up.
Any Hints welcome !
@H1ghtower sounds like a screensaver issue since the monitor actually turns on
Deactivate screensaver if not done yet.
That may be a cause.
How do you controll the display? Are you using a command like
/opt/vc/nin/tvservice -por just
And is the display connected via hdmi?
If that’s the case you could try the following:
In /boot/config.txt add
hdmi_blanking=1and reboot. Now try HDMI Output OFF with
vcgencmd display_power 0and HDMI Output ON with
vcgencmd display_power 1instead of the command above.
