as processors and peripherals, that employ power management capabilities.

With these utilities, you enable power management modes and specify the

amount of time to wait before shutting off each component in order to save

power.

4.8.1 Display Monitors and DPMS

Consult the hardware documentation for any display monitor (screen) that

is attached to your system before implementing power management.

___ Warning – Monitors (screens) that do not support Power

Management _________________________________________

Monitors (display screens) that do not support DPMS (Display

Power Management Signaling) can be damaged if the DPMS

signal is activated. Consult the hardware documentation that

came with your monitor, or telephone the manufacturer if you do

not have documentation.

The time it takes a DPMS-compatible monitor to come out of a

power-saving state depends on the monitor. You will observe that the

longer the monitor is in the power-off state, the longer it takes for the

display to return as a result of mouse or keyboard activity. This is the

result of the monitor phosphor cooling down and the time required to heat

it back up. In addition, there are some monitors (for example, the

VRC21-HX) that turn off the Power LED (display light) when they enter

the

DPMS_OFF state. Moving the mouse or typing at the keyboard will not

bring the display back. Only by pressing the power switch off, then on

again, will mouse and keyboard activity cause the display to return.

Because of the varying behavior of monitors when in certain DPMS states,

you should read your monitor speciﬁcation to ﬁnd out about the expected

behavior and other visual features while in each power-savings state.
