Turn off Win10 display(s) via OpenSSH
There are a lot of solutions to turn off display locally on a Windows10 machine. They all are some form of the following SendMessage line. There's also little executables like nircmd that do this. However there seems to be some limitation when running any of those via OpenSSH. Since my OpenSSH is configured to use the exact same credentials as my local user i can't really figure out why nothing happens. The ps script versions return a simple 1, and solutions like nircmd just return nothing at all. Not even an error. Any insight what might happen here and how to make it work?
Sample script:
powershell (Add-Type '[DllImport("user32.dll")]^public static extern int SendMessage(int hWnd, int hMsg, int wParam, int lParam);' -Name a -Pas)::SendMessage(-1,0x0112,0xF170,2)
Source
edit: maybe i should add that other nircmd options like mute audio work without any problems.

Some more utilities to try: Turn Off Monitor or Display Power Off Utility or ScreenOff.

Thx, but those all have the same effect. They work locally on the machine, but not executed via ssh. That leads me to believe that somehow the ssh can't see/enumerate/detect displays to shut off. But without any log or error message i'm out of ideas.

Since you are using OpenSSH, this means you are going form Linux to Windows, as it really would not be a go to for Windows to Windows, just use normal Windows PSRemoting. Now, all that being said, why are you trying to turn off a Windows display from a Linux box remotely. Just curious, or are you on a local Windows using an SSH session, again, not sure why you'd want to do that.

It's a simple convenience thing. I want to be able to switch the displays on my desktop on and off from a home automation system running on a raspberry pi. Of course there are solutions like automatic switch off in idle time for the displays but that's not on demand and i just like to switch between them at my convenience. Not the end of the world, just became a curiosity thing since everything else works (e.g. switching audio devices).
