Hi.
Is it possible to have independent power saving mode on each monitor? Turn ON/OFF by hotkey or idle timeout ( based on mouse movements on a specific monitor ) ??

example of use:
I have 2 monitors, on the main monitor I watch a movie.
On the next monitor I have open windows, files, programs (organized, in working).
So I would like to switch It to energy-saving mode, without changing profiles.
You know, profile switching moves windows to the active monitor, etc...

It would be best to just switch unused monitor to power saving mode with HOTKEY.

So elegant and simple

How to do it?
I think that you could take advantage of DDC/CI Monitor Control Command Set (MCCS).
Send a command to monitor ordering the switch to energy-saving mode.

With the MCCS you can do a lot more.
See for example the softMCCS software.
