Turn off Screen.bat

powershell (Add-Type '[DllImport(\"user32.dll\")]^public static extern int PostMessage(int hWnd, int hMsg, int wParam, int lParam);' -Name a -Pas)::PostMessage(-1,0x0112,0xF170,2)

Not that I'm aware of. AFAIK, it just turns off all of them.

Very nice. I dropped it into my scripts folder and placed a shortcut on my desktop. I already had something similar on Linux and I am glad to see someone already did this for Windows.

Great script! Just a note, .NET 3.5 is required on Windows 11 for this to function. Otherwise you'd get mscoree.dll error.

Great script! Just wanted to add this here in case someone needs it, if you want the screen shutdown to be delayed by a certain amount of time after you run the .bat file, you can add this before the .bat file code:

@echo off
timeout /t x >nul

x is the number of seconds you want the delay for. Really helpful if you use chrome remote desktop :-)

Any way to ensure that the screen is turned back on only when the mouse is clicked and not when moved?

I am not aware of a windows setting for that. Any activity will bring it back. If there is YouTube video playing in the background, it can bring the screen back on too. So, if you want to just listen, open another tab in your browser so that the YouTube video is not in the active tab.

Hmm, during times when listening to some audio on the computer and turning the screen off, it works and isn't turned back on.
Hopefully there are ways to turn the screen back on only when there is certain event - in this case a mouse click.

Did you ever find a solution to this? Want to do the same thing. Thanks!

This shuts off the screen and locks the desktop. Would be nice if there was a way to just shutoff the screen.

AFAIK, the Windows OS will wake the screen on any KB or mouse event, and will bring you to the unlock screen (or desktop if security is disabled).

Is this still working for you guys? for me the screen turns off then immediatley turns back on - no mouse or keyboard movements (by me)...

@Shazib
Can confirm that it works for me with Windows 10 Pro 22H2.

First of all thanks to EugeneLoy and unknown for me the author of the command :-)
Today 2.6.2023 - it works for me. Conditions - Win10 22H2. Two monitors. Both displays are turned off one time.

Cheers.

FYI I've discovered that this doesn't play nice with my monitor that supports DDC/CI control. https://github.com/xanderfrangos/twinkle-tray/ works though.
