Using the Monitor Off (monitor off using your keyboard) Utility is a quick and easy way to turn off your monitor when you step away from your computer.

Tip: Although this utility is claiming to turn off the monitor, it is actually putting the monitor into Standby. Although Standby mode is similar to turning off your monitor, we’d still recommend that you turn off the monitor if you’re going to be away from the computer for an extended period of time.
