      I’m using a monitor in my project that does NOT have HDMI. I’m using an DVI to HDMI adapter to make it work.

      Do I have any options for allowing the monitor to go to sleep and then wake up when needed? Note that a PIR sensor does not work because I don’t have HDMI.

        @cheapdad , Hi, what’s the connection between HDMI and PIR? I built three mirrors, all three have adapters and use PIR.

          @cheapdad u can still turn off the hdmi output… the monitor might show ‘no input’… which mine do…

          so I went to blanking (hide all modules)…

            I understood that the PIR sensor uses HDMI-CEC to communicate shutting off the monitor. Is that not true?

              @cheapdad no. PIR signals software. there are three different ways

                How do you do that?

                  I’m sorry but I don’t understand this at all.

                  No, the PIR sensor does not use HDMI-CEC?

                  What signals software are you referring to?

                  What are the 3 different ways?

                    @cheapdad sorry, typo.

                    phone didn’t like the word PIR

                    pir is a heat sensor
                    it signals, heat, and then no heat. that is all.
                    software has to make intelligent work from that

                    the PIR modules see heat, and turns ON the display
                    they see no heat, and some time later turns OFF the display

                    actually 4 ways to turn on/off the display/source, all commands u can issue

                    tvservice
                    vcgencmd
                    dpms
                    and the latest to turn off the display
                    cec-utils

                    many of the pir modules allow you to choose which approach u want to use.

                    some people are unable to use any of those (me)

                    so I wrote a module to hide the modules

                      @cheapdad and there two more ways, that need software

                      you can control a switch/relay that turn the power off /on to the display, for those monitors that don’t have internal controls that prevent this. (my monitors do not come back on after a power failure)

                      and you can modify the logic of the didplay with a relay/switch to turn on/off the backlight of the display. so the display is powered on, but not active

                        @cheapdad , in my mirrors the PIR sensor stop the display of the modules but the monitor continues to work, it display a black screen.
