This monitor has a built-in power management system called PowerSaver. This sys-
tem saves energy by switching your monitor into a low-power mode when it has not
been used for a certain amount of time. The monitor automatically returns to normal-
operation when you press a key on the keyboard. For energy conservation, turn your
monitor OFF when it is not needed, or when leaving it unattended for long periods.
