Technical Features
Power saving function (user sensor/power saving mode)
This monitor meets the power-saving guidelines set by VESA, ENERGY STAR, and NUTEK. If the monitor is connected to a computer
or video graphics board that is DPMS (Display Power Management Signaling) compliant, the monitor will automatically enter the power
saving mode. It automatically enters the low power consumption mode when the user sensor detects the absence of a user.
Power consumption state Power consumption AC power indicator (!) (power) indicator
normal operation 35 W green green
1 low power consumption mode <8 W green green and orange alternate
2 power saving mode <3 W orange orange
C!) (power): off < 3 w red off
AC power: off o w off off
1 Low power consumption mode (user sensor)
When the user sensor in the monitor detects the absence of a user,
the monitor enters low power consumption mode after about 20
seconds. In low power consumption mode, the monitor is in a
power saving state and shuts off power to all circuitry (except for
that of the sensors) regardless of the setting of the computer.
The monitor returns to normal operation mode when the presence
of a user is detected by the user sensor.
When the monitor enters the power saving mode (as set according
to the computer’s settings), the power saving mode takes
precedence over the low power consumption mode. In this case,
the monitor stays in the power saving mode regardless of the
presence or absence of a user.
To return the monitor to normal operation mode, reset the
computer’s power saving mode.
Note
The user sensor detects the presence/absence of a user up to a distance of
approximately 60 cm from the screen surface. However, this distance may
vary depending on the user’s clothes or the brightness of the surrounding
area. If user detection fails due to the ambient conditions of the
surrounding area, set the user sensor to OFF. If your monitor does not
automatically return from low power consumption mode due to the failure
of the user sensor to detect the presence of a user, press the Cl) (power)
switch twice to turn the monitor off and then on.
2 Power saving mode
DPMS defines three power saving states according to the state of
the sync signals supplied from the computer. This monitor’s
power consumption is input at approximately 3 W in all of these
states if the power saving function is set to ON.
When your computer enters in the power saving mode, the input
signal is cut and NO INPUT SIGNAL appears on the screen.
After a few seconds, the monitor enters power saving mode.
Power saving Sync signal state
state
suspend (sleep)* horizontal: on / vertical: off
standby (sleep)* horizontal: off / vertical: on
active off (deep sleep)* horizontal: off / vertical: on
* “Sleep” and “deep sleep” are power saving modes defined by the
Environmental Protection Agency.
Note
The power saving function may not work nonnally if sync signals other
than those listed above are supplied. In such a case, set the power saving
function to OFF.
