I found this passage in your code:

    _togglePresence: function _togglePresence(isPresent) {
        if (isPresent) {
            // Check if hdmi output is already on
            exec("/opt/vc/bin/tvservice -s").stdout.on('data', function(data) {
                if (data.indexOf("0x120002") !== -1)
                    exec("/opt/vc/bin/tvservice --preferred && chvt 6 && chvt 7", null);
            });
        } else {
            exec("/opt/vc/bin/tvservice -o", null);
        }
    }

So you are using “tvserice -o” which seems not to work for me.
would this be an alternative? Link

Executing the commands vom @E3V3A here Link brings the Monitor Signal back, but only 1 time.

Any idea?

Hi, using this command brings back the Monitor signal:

xset -display :0 -dpms

I just implemented vcgencmd it looks like it is a bit quicker. I will check it out the next few days and will push it if everything works.

Yeah, but that only work with Rapsberry Piss , so if you want it to work on other devices, you need to use xset, and if you want to use xset on the Pi, you now also need to tell it that the blank screen should be black, with xsetroot -display :0 -solid black.

idoodler

@e3v3a I think xset just blanks the screen without powering off the HDMI signal?

@bobbythemoh Can you please post your pm2 log. You can optain it by executing pm2 log MagicMirror if you are using pm2.

I just detected some unhandled rejections which may cause the black screen.

@bobbythemoh Ok, thanks. No unhandled rejections.

bobbythemoh

@idoodler , did “vcgencmd” solve the issue?

idoodler

@bobbythemoh No. I think there is an issue within the communication module for the Miniserver. If the module crashes when the screen is turned off the screen will never be turned on again and vice versa.
