Answer 1

Turning off monitor is completely different from operating system function. In a windows system it shows just the output given by the System. It does not take any input to the system. So you cannot add any functionality to your program using the power button of the monitor. If the monitor turns off automatically by the power management system you can trigger events but not by pressing power button of monitor.
