    @sdetweil I’m able to VNC to the pi, and when I move the mouse the TV will turn back on. It will then stay on for 5 minutes before TV lose HDMI connection. I have also keep the VNC connection open and watch the TV lose signal and the app continue to work.

    I have missed with the PI config file to increase the HDMI signal but same outcome.

    Also, I did setup CEC, 6 months ago, to control when the TV turns on and off. I was thinking there was an issues with the pi, so I created a con job to turn the TV, then restart the PI. This setting worked for about a week. Now if I do not restart the PI it comes up with no HDMI signal.

    I wondering if its an issues with the TV itself?

      @danjvd if you stop MagicMirror, does the screen turn off?

        @sdetweil I have not tried that. I will let you know later today of the outcome.

        Thanks Sam!

          @danjvd It sounds as if your screen saver wasn’t disabled correctly?

            @zoltan if u run my install script it will turn off screensavers if u say yes.

            also a separate script if u change your mind

            we are still waiting to see if it’s mm related or not

              @sdetweil With MM turned off, the Pi keep display HDMI without issues. Are there any error logs that I should look at?

              @Zoltan Thanks for the steps. I did complete this when I first created the MM pi over a year ago. It always a good thing to veirfy!

                @danjvd ok so this means one of the modules you are using is turning off the display

                can you do

                grep module: ~/MagicMirror/config/config.js
                

                to show us a list of the modules used

                  @sdetweil said in Losing display output after 5 minutes:

                  grep module: ~/MagicMirror/config/config.js

                  Here are the modules that I have been using for the past 6 months before the issues started. I have not added/removed any modules after this setup, only updates.

                    module: "alert",
                    module: 'MMM-BackgroundSlideshow',
                    module: "updatenotification",
                    module: "clock",
                    module: 'MMM-CalendarExt2',
                    module: "MMM-OpenWeatherMapForecast",

                    @danjvd weird.

                    so next I would disable one module at a time.
                    (not the defaults)

                    add

                    disabled:true,
                    

                    after the module: line

                      Before I was able to start disabling modules, MM would not start this morning. There are the logs that I got from pm2:
