BlackTop – Turn Off PC Monitor Using a Preset Hotkey
For Windows 32-bit
For Windows 64-bit
The way BlackTop works is again very simple any easy, and it will sit in the system tray waiting for you to need to put the screen into a low power state. Then all you have to do is press the program hotkey combination of Ctrl+Alt+B and it will immediately put the screen to sleep. Press ant key or move the mouse/touchpad to bring the screen back to life.
