Automatically adjusting the screen brightness
(light sensor)

This monitor is provided with a sensor to detect the brightness of
the surrounding area (light sensor). This sensor is used to
automatically adjust the brightness of the screen.

First press the

(+)/

(–) buttons to select

(LIGHT

SENSOR) and press the OK button. Then press the

(+)/

(–) buttons to select either ON or OFF.

When you select ON, the monitor automatically adjusts the screen
brightness according to the brightness of the surroundings. For
more information about this function, see “Automatic brightness
adjustment function (light sensor)” on page 18.

Note

If this function is set to ON, the value of the BACKLIGHT menu does not
change. If the screen brightness is still not appropriate after the automatic
adjustment, you can manually adjust the backlight. After the backlight
adjustment is made, the monitor automatically adjusts the screen
brightness in accordance with the new backlight value.

Setting up the power saving mode

This monitor has a function which enables it to enter the power
save mode automatically according to the power saving settings
of the computer. You can prevent the monitor from entering the
power saving mode by setting the following option to OFF.

First press the

(+)/

(–) buttons to select

(POWER

SAVE) and press the OK button. Then press the

(+)/

(–) buttons to select either ON or OFF.

Using the user sensor

The user sensor function enables the monitor to enter the low
power consumption mode when no one is present in front of the
monitor.

First press the

(+)/

(–) buttons to select

(USER

SENSOR) and press the OK button. Then press the

(+)/

(–) buttons to select either ON or OFF.

If you select ON, the monitor automatically enters the low power
consumption mode when you move away from the front of the
monitor. For more information about the low power consumption
mode, see “Power saving function (user sensor/power saving
mode)” on page 17.

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.

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

(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.

* “Sleep” and “deep sleep” are power saving modes defined by the

Environmental Protection Agency.

Note

The power saving function may not work normally if sync signals other
than those listed above are supplied. In such a case, set the power saving
function to OFF.
