Screen not being turned off when monitor is HDMI.

[scyto]

Describe the bug
I have a 7" HDMI monitor connected.
I have 'turn screen off while sleeping' enabled vai touch interface
However screen doesn't go to sleep

To Reproduce
Steps to reproduce the behavior:
install octodash on pi4 with HDMI monitor that supports DPMS
enable sleeping
set ocotprint to disconnect and force sleeping on octodash

Expected behavior
screen go blank / off when sleeping

Screenshots
screen stays on

General Information:
Pi4 with HDMI screen 1280x720
OctoPrint version : 1.6.1
OctoPi version : 0.18.0
OctoDash Version 0.0.5

Additional context
running xset dpms force standby correctly blanks the screen
is there a way to force octodash to send this command?
(it woke up beautifully when i touched the screen)

this is active in my config.json

                        "touchscreen": true,
                        "turnScreenOffWhileSleeping": true,
                        "turnOnPrinterWhenExitingSleep": true,
                        "preferPreviewWhilePrinting": false,
                        "previewProgressCircle": false,
                        "screenSleepCommand": "xset dpms force standby",
                        "screenWakeupCommand": "xset s off && xset -dpms && xset s noblank"

note i can only run the xset dpms commands via SSH once i have done
export DISPLAY=:0
this doesn't seem to be done by default
