i was hoping more positive suggestions, the button one i cant do it cuz the monitor is too far and i cant reach it from the desk,
the second thing is, why the hell do i installed an operating system if he is unable to do what i need, hmm...

i managed to make a program (called poweroff) to "suspend" my monitor, with a button of a remote control (this is done tru a batch command file when the specific key is pressed)
Code:
@echo off
poweroff.exe monitor_off -immediate
exit
(i have the RC from a TV-tunner board), with some program i manage to reroute the button press destinations, to transform the remote in a general purpose one (the RC in the picture is exactly the same as mine...)

the drawback of this, is that when i press anykey on the keyboard, or i slighly move the mouse, the monitor turns back on, this will not permit me to work with the computer with the monitor off,
example: i want to use some keyboard shortcuts or remote control buttons, to change the "current state" of the computer...
conclusion, i need some specific shortcut (from my keyb or RC ) to return the monitor ON state... so if native windows can't help me, a third party software will do just fine...
