      Thanks, @cruunnerr. Very comprehensive. Can I suggest you also add how to black out but not disable the monitor? I’ve seen this question a few times. It is often important when users:

      1. want to still use the integrated audio out of a monitor, or
      2. are using a TV style display where it will turn off without signal, and then cannot be turned back on by the Pi.

      I’ve seen solutions using xset dpms force off and another using chvt to display a blank virtual terminal, but there may be other (even better) solutions.

      Problem with config or JavaScript? Copy/paste it into JSHint.
      Check out the detailed walkthroughs on install, config, modules, etc.

        is there a way to use a PIR sensor and the PIR module to make the PI load a black screen saver so that it looks like the screen went off but really didnt and then when the PIR sensor picks up motion the screen saver is “turned off” like it would normally do.?

          yes it is.

          Just use the external script from this tutorial. Change the content of the monitor_off.sh and monitor_on.sh to the following:

          monitor_off:

          export DISPLAY=:0
          xset dpms force off
          

          monitor_on:

          export DISPLAY=:0
          xset dpms force on
          

          I will add this options to the tutorial later. ;)

            Those commands look familiar. :-)

                Alright, i add this option to the tutorial. Hope you enjoy :)

                If there are any suggestions on the scripts i am using please tell me. I am not a programmer so it could be, that the scripts aren’t as “clean” as they could be.

                  1. disable the HDMI port with
                  vcgencmd display_power 0
                  

                  and enable with

                  vcgencmd display_power 1
                  

                  Most monitors then go into standby. Some also show ‘NO Signal’.

                        Most modern monitors also have a PowerSave function that completely turn off the monitor when there is no HDMI signal, after a set amount of time. So I guess experimentation will be needed as to what really happen after you have turned it off using either:

                        1. vcgencmd display_power 0
                        2. sudo tvservice -o
                        3. DISPLAY=:0 xset dpms force off (Notice, it’s not necessary to export!)
                        4. xset -display :0 dpms force off

                        The first 2 turn off HDMI and most likely put your monitor into PowerSave mode, eventually.
                        The last 2 only blanks the screen (visible when dark), and does not disable HDMI signals.
