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.

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.

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.

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.

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.

English, German, French, Spanish, Italian and Japanese versions 
of the on-screen menus are available. The default setting is

This monitor meets the power-saving guidelines set by VESA, 

E

NERGY 

S

TAR, 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.

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.

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 

1 (power) 

switch twice to turn the monitor off and then on.

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.

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.
