ScreenOff is a "boss screen". When run, it blanks the screen, so that it appears turned off, and it exits if you click the mouse

ScreenOff was developed to be a "boss screen" which will blank your PC screen, so that it appears turned off, and it exits if you click the mouse. A good idea would be to create a shortcut to it, assign a hotkey to the shortcut, and stick a piece of painted scotch tape on the screen LED.

That way, when you activate ScreenOff, nobody will be able to tell it's on, so stop turning the monitor on and off all the time when the boss comes in just to show that you are working instead of playing solitaire.
