        I’m pretty sure you can have the raspi turn on and off the screen through the hdmi. I will have to check on that.

        sure I works !

        I use +/- same config of you :
        RPI3B+ or RPI4 + HDMI/VGA apdator + VGA monitor (24pcs)
        and my monitor shutdown and turn on with pir sensor

          A little off-topic, nevertheless relevant: I have a laptop with no VGA port and I still use a very old ViewSonic CRT 21" monitor with it, using a HDMI-VGA adapter; When my computer sends the sleep signal to my external monitor through the adapter, the monitor does sleep successfully, so I assume there must be a way to make the RBPI send the same kind of signal through the HDMI port.

              Hey! So, there are probably a lot of ways to turn on and off your monitors, but I’m gonna link the one that worked for me. I was using MMM-Remote-Control, but you can take those commands and run them expecting to turn on and off.

                I’m just changing the screen to black instead of shutting it off.

                  @dhanushx012 I am like the guy who started this topic. I can’t just blank the screen by turning the hdmi output off on the pi. And, I can’t power off the monitor using CEC commands. Even though I am using a HDMI instead of VGA I have the simililar issues.

                  Q: why not turn hdmi output off?
                  A: Because my tv monitor detects no hdmi signal and just has to scream at me about it with a not very cute logo and ugly text. There are no settings within the monitor to turn off that message.

                  Q: Why not power the monitor on/off?
                  A: I can’t power it off and on using the CEC commands because I also get a annoying message and logo from the monitor when it starts up.

                  Q: why do you have to use that monitor when it’s easy to get another one that will work either way?
                  A: I have to use a cheap VIZIO on sale for $32 US that I got. I don’t have a spare lcd panel around to use. Some of us can’t simply buy another monitor. We are using what we have. So far all together with my pi, my $32 monitor, and some cables, molding (frame), glass, and film and a gestures sensor for $2.50. I’ve managed to spend just around $120.

                  Problem: Same as the guy who originally posted. I need the monitor to be on at all times and sending a signal because of the first two issues listed. So, I am trying to use the MMM-grove-gestures built in way to hide all the modules… but some of the modules don’t behave and turn themselves back on. Super annoying. I’m still debugging that. I think it is inside the currentweather and weatherforecast modules

                  Solution: get the screen to turn black

                  And getting it to do that is the crux of the problem.
