    @jbat66 - thanks for the offer. If you do wind up sharing your work, I will take a look and see if it works for me.

    I don’t run any remote control module, and don’t find the “MMM-remote” you reference when I search. I do, however, find at least two (2) different modules called “MMM-Remote-Control” by two different authors. Do you mean one of those?

    My progress so far is that I can get the monitor to turn off using the following script (called by a cron job), but the monitor then turns back on after ~10-15 seconds:

    #!/bin/bash
    
    # Script to turn off monitor display when called by crontab
    export WAYLAND_DISPLAY=wayland-1
    export XDG_RUNTIME_DIR=/run/user/1000
    /usr/bin/wlr-randr --output HDMI-A-1 --off

      @JohnGalt Can you add vc4.force_hotplug=1 to cmdline.txt (on existing line) and check if behaviour changes? Add a space at the end of the line, save and reboot.

      Assuming you are using the first hdmi port closer to the usb c. If using the 2nd port then change the hot plug number to 2

        Sorry I should have been more clear.

          vc4.force_hotplug

          That does appear to work! So far I have tried it on two different Pi 4 instances, and each responded to a script called in crontab to turn off the monitor display, and then a script to turn it back on, as expected.

          Thanks.

            @1a2a3a Thank you Thank you Thank you… That worked for me as well… Message me, and I will get you a pizza like I promised to anyone who could get my pi4 running latest rasbian to turn off the monitor. Adding vc4.force_hotplug=1 to the end of the line in /boot/cmdline.txt did the trick along with using wlr-randr!!

            I’m serious about the pizza.

              @jbat66 all good mate. I’m likely in a different geographic region to you. But anyway it was an issue that someone in GitHub that resolved for me so I can’t really take credit. I would point you to the GitHub but it was quite awhile back hence I can’t find the link anymore, therefore I went into my txt file and gave you guys the code.

                @jbat66 I know this thread isn’t about getting MMM-Remote-Control to update with this but I was curious if you know how I could go about that.

                  @devonian69 Do you mean just a normal update for the module?

                    Hey guys,

                    So how did you get this to work? vc4.force_hotplug ive added that to /boot/firmware/cmdline.txt

                    But now what?

                    Im running Raspbian on a Pi 5, so not sure if all of this is even for bookwork :(

                    Thanks

                      @liminal1 note that rapios on pi4 and 5 use a new display manager called Wayland.

                      so all the commands for display MGMT have changed. see the commands posted above.

                      or set the os back to x11. see the raspi-config command
