      I have an opposite behavior after updating MM.
      After boot/reboot the mirror is on my HDMI Display but after awhile it disappears.
      The motion sensor only activates the backlight of the display but no content.
      In the webbrowser and with VNC viewer all is normal.
      If i send

      /opt/vc/bin/tvservice -p; sudo /bin/chvt 6; sudo /bin/chvt 7
      

      it comes on again on HDMI but not stays.

      Is there something like a screensaver for HDMI display active?

        Hi,
        it might be a problem with screen blanking.
        If you edit your /boot/cmdline.txt like in this description it might solve the problem.

          @wishmaster270 if you used the automated install script,m it will turn screen saver off for you if you reply yes…

          you can also run the screensaver off script part from the installation repo here
          https://github.com/sdetweil/MagicMirror_scripts

          it will figure out what system and set it off appropriately.

              @wishmaster270 got it working with your tutorial but once the monitor goes into sleep mode, after not receiving a signal, it doesn’t turn back on unless I unplug and plug it back in.

                @elleclouds Hi, do you see any output of the Gpio module in the log file?

                  the cmdline.txt was already ok , i really had to install xscreensaver and disable screensaver to solve my problem.

                      @elleclouds Hi, do you see any output of the Gpio module in the log file?

                      So I got it working with your tutorial. My only issue now is when the monitor doesn’t have a signal it turns completely off and won’t turn back on unless its unplugged and plugged back in. Is there a way to keep the monitor on, just asleep so that the HDMI signal when signaled, activates the screen?

                        Hi,
                        it depends on your monitor. Maybe there is an option in the monitor configuration menu.
                        If not you can configure the MMM-Screen-Powersave-Notification module to only hide all modules and show the black background instead of turning the hdmi off (hideInsteadShutoff option)
