    I’m using a Raspberry Pi 4 Model B Rev 1.2 for my mirror. In attempting to shut off the hdmi to the mirror using both MMM-RemoteControl, or a bash file using vcgencmd display_power 0/1, the monitor turns back on within 12 seconds. Research indicates that it’s due to kernel control on the P1 4 model. Oddly, no one in the forum seems to be experiencing this. Any suggestions or tips that I can employ? Thank you.

      off command is
      (sudo /usr/bin/vcgencmd display_power 0) >/dev/null
      on command is
      (sudo /usr/bin/vcgencmd display_power 1) >/dev/null

          @Stroke-0 No Problems here. Im using MMM-RemoteControl and a PI4. I also use MMM-NewPir to turn the Monitor off.

            A (or my) Rpi4 has two HDMI ports. So you should add also the HDMI port 0 or 1 (or id 2 and id 7). docs

            Status screen:

            vcgencmd display_power -1 2 | grep -q "1" && echo "on" || echo "off"
            vcgencmd display_power -1 7 | grep -q "1" && echo "on" || echo "off"
            

            Regards,
            Bert

              I had the same issue, I use MMM-PIR-Sensor-Lite to switch the monitor off and on again. On the command line “vcgencmd display_power 0” does not work, the return is always: “display_power=1”.

              I have tried a few things, they all did not work.
              Edit the “config.txt” in the “/boot” directory.

              Go to:

              “# Enable DRM VC4 V3D driver
              dtoverlay=vc4-kms-v3d
              max_framebuffers=2”

              And change “dtoverlay=vc4-kms-v3d” to “dtoverlay=vc4-fkms-v3d”.

              There is a bug in the “vc4-kms-v3d” driver.

              After changing in the “config.txt” “vcgencmd display_power 0” returns a “display_power=0”.

              MMM-PIR-Sensor-Lite now works as desired.

                @MiPraSo Well done! Thank you. Your solution works perfectly. I do not understand why others are not experiencing the same issue however, they now have a solution. Thank you, again.
