"--set-power-mode on" is not working (windows)

[m4k2k]

Hi,

I just stumbled upon this great project - unfortunately, some commands are not working.. (others work)

• Monitor manufacturer and model number: LG 34GL750
• Input source (HDMI, VGA, display port, etc.): display port (directly connected)
• Output device (video card, discrete graphics, etc.): discrete nvidia graphics card (with latest driver - 528.02)
• Operating system: Win11x64
• Python version: python 3.10
• monitorcontrol version (monitorcontrol --version): 3.0.2 (via pip)

1. monitorcontrol --monitor 1 --set-power-mode off_soft

• Result: Monitor powers off (no info in console)

2. monitorcontrol --monitor 1 --set-power-mode on

• Result: nothing happens (no info in console)

I have two questions:

• is this a "known issue"?
• are there any workarounds?

Thanks - Markus

This sounds related to #117. My best guess is that some monitors do not respond to DDC-CI when off.
