On macOS some monitors (eg LG) will power off as macOS is not "talking" to the monitor and telling it to stay on.
A really great addition would be a checkbox that sends any DDC value to the monitor (eg. adjust something like brightness +then- so no effect visible), this like the volume prevents the message from appearing. The message is displayed despite having auto standby turned off on the monitor.

With this addition we could leave auto standby on and the monitor would power off after macOS goes to sleep due to inactivity.

This would be a fantastic upgrade.

Hmm. Shoudn't the monitor stay on if the Mac sends video? :) What kind of display is it?

Anyway, I recommend switching to BetterDisplay and use the app's CLI features to send any DDC command with a script scheduled to run every 10 minutes or so. You can also use m1ddc for this purpose if you need a lighter solution.
