Note: Green monitors detect the V/H
SYNC signals to turn off their electron guns.
It is important to realize that the CRT con-
sumes the most power (several hundred
watts) of any system. To really save energy,
you must shut it down when not in use.
Green monitors (also known as Energy Star
monitors) reduce power usage by 90% with-
out actually turing off the CRT. To make a
green monitor function properly you MUST
use Video Off Method = V/H Sync, because
this tells the Green Monitor to shut down. If
you incorrectly use the "Blank Screen" set-
ting then you will just get a blank screen
which still consumes 100% power. If you
have a screensaver running, then you will
not have CPU inactivity, and the standard
BIOS options will not shut the CRT down
ever. So, turn OFF your screensaver in the
WINDOWS control panel, not in the BIOS.
Video Off In Suspend
This option defines the time frame in which the video will be
disabled under current power management settings. The set-
tings are:
Always On: System BIOS will never turn off the
screen.
Suspend => Off: System BIOS turns of the screen
when system is in SUSPEND mode.
The choices are:
Always On / Suspend -> Off
