Programmatically control monitor power in Windows?

Question

Windows

The article habrahabr.ru/blogs/linux/95934 describes how to programmatically turn off and turn on the monitor (similar to a button) in Linux. I am looking for the possibility of using such functionality in Windows, in particular, such a utility could automate the following tasks:
1) Turning on the monitor when the OS boots and turning it off when shutting down.
2) Turn off the monitor when the session is locked and turn it on when it is unlocked.
3) Turning off the monitor while running a remote administration program like Radmin.
I found only two programs that can control the power of the monitor:
1) www.entechtaiwan.com/lib/softmccs.shtm - works, but allows you to turn off the monitor only from the GUI. Librarywww.entechtaiwan.com/lib/softosd.shtm on the basis of which the program works is not available even in demo mode.
2) www.nicomsoft.com/wini2cddc - a demo is available that does not support x64. The required function is present - www.nicomsoft.com/wini2cddc/help/api.htm#SetMonito... but the cost is prohibitive.

Answer 1

NirCmd allows, like a lot of other similar utilities, only to put the monitor into low power mode. This is a completely different function, not similar to turning off the monitor with a button.

Answer 2

Take a look at this utility , maybe it is what you need.

Answer 4

My softOSD service (the one on the first link) caused an empty red screen to appear at the start of the OS (not that kind of BSOD). What I didn’t sin on: winlocker virus, dying vidyaha (GTX 670), crooked drivers, etc. I changed firewood, checked the computer, heated the video card - nothing showed a flaw. Moreover, it was possible to bypass the red screen only by launching a full-screen application immediately (for example, a game immediately after the appearance of the desktop). Only the "Windows Journal" in the end showed me that this service fails at startup. On the computer, apparently, it appeared with a crooked driver from the Dell U2412M monitor.

Answer 5

Strangely, the
MonPower.exe -off command
doesn't work even as an Administrator.
