I want to be able to 'put the display to sleep' on one of my two monitors when it isn't needed, so it doesn't distract me or use unnecessary power.
Ideally, the display would be asleep, but the OS would remain in dual-monitor mode, so I could still have a variety of windows open in the sleeping monitor's display space, which would mean I wouldn't have to keep switching between single- and dual-monitor modes.
That said, I'd also consider a solution that made it easy to toggle between single- and dual-monitor modes without navigating several system menus.
This used to work for me perfectly with a result of a completely black screen. Now when I use it, it makes an all black screen but a pi symbol shows up near the middle and if you click on it, it is a way to switch from all white to all black. I just wish it would go away as I want just an all black screen with no "pi" symbol on it. Any idea what that might be and how to get rid of it? I am speaking of the VB6 program, .htm file. – None – 2015-04-29T01:59:58.447
2:( 2017 - none of the 8 answers here is answering the question -> make one of the monitors sleep but keeping it connected for OS. – icl7126 – 2017-02-09T15:27:04.787
2When you say 'not manually' you mean 'without physically powering off the monitor'? – Shinrai – 2011-04-08T21:48:44.273
So you want it to do it automatically? Like actually shut the monitor off or just stop displaying to it so it goes to sleep? Also there needs to be some kind of condition for this to happen it won't just magically turn off when you think your ready for one to shut down. Could you please provide some more details? – Supercereal – 2011-04-08T21:49:38.920

Using Nircmd (http://www.nirsoft.net/utils/nircmd.html) you can turn off a monitor via command line (but I do not tested with a desktop, only with a laptop). But I don't know how to change monitors with a command line or to choose only one to turn off. I also think if you only switch from 2-monitors to 1-monitor (like hitting fn+f4 from a laptop) the screen with no signal will enter in a standby mode after some time ("almost" turned off).

– kokbira – 2011-04-08T23:42:05.823@Shinrai--yes, without physically powering it off. I want to "put the display to sleep," so that it doesn't distract me or consume power when I don't need it. – Stew – 2011-06-15T12:52:09.487
