DOME DPMS screen saver
The DOME Display Power Management Signaling, or DPMS,
screen saver for Windows NT 4.0 offers a powerful and flexible
way for you to reduce the amount of power your monitor uses
and to extend the life of its CRT.
How the screen saver works
Like other Windows screen savers, the DOME DPMS screen
saver is invoked after the system has received no user input for
a specified number of minutes. Unlike other screen savers, how-
ever, the DOME DPMS screen saver does not display anything
on the monitor itself. Rather, it launches another screen saver that
you select to protect the display. Then, after a predetermined
number of minutes, it uses DPMS to shut off the video power to
the display.
There are two delay periods before DPMS is invoked.
• First, the standard screen-saver delay from the last user input
until the screen saver launches.
• Second, from the time the screen saver launches to the moment
DPMS shuts off the video power to the monitor. After this
delay, DPMS places the monitor in power-off mode.
The DOME DPMS screen saver allows you to select the other
screen saver to use before it invokes power-off mode. It also
allows you to specify up to four time periods during the day,
with different settings for if or when power-off mode is invoked
during each period.
