      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.

                @sdetweil I just use the Standard setting in my config.js.
                Standard = use vgencmd

                  @OberfragGER we have discovered that some pi firmware (updated under the covers by some kernel updates) causes the vcgencmd to not work,
