UNSOLVED MMM-RemoteControl or vcgencmd Issue

[Stroke 0]

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.

@Stroke-0 my pi4 doesn’t have an issue

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"
