Hi everyone
Is there a way to know if screen is ON or OFF?

I do not know of any way to do so.

"GetDevicePowerState sometimes works for monitors. If it's present, you can open the \\.\LCD device. Close it immediately after you've finished with it.

Essentially, you're out of luck -- there is no reliable way to detect the monitor power state, short of writing a device driver and filtering all of the power IRPs up and down the display driver chain. And that's not very reliable either."
