ÅWARNING: To reduce the risk of electric shock or damage to your
equipment: Do not disable the power cord grounding plug. The
grounding plug is an important safety feature.
Plug the power cord into a grounded (earthed) electrical outlet that is
easily accessible at all times.
Disconnect power from the monitor by unplugging the power cord
from the electrical outlet.
Do not place anything on power cords or cables. Arrange them so
that no one may accidentally step on or trip over them. Do not pull on
a cord or cable. When unplugging from the electrical outlet, grasp
the cord by the plug.
ÄCAUTION: Burn-in image damage may occur on monitors that
display the same static image on screen for a prolonged period of
time. To avoid burn-in image damage on your monitor screen, you
should always activate a screen saver application or turn off the
monitor when it is not in use for a prolonged period of time.
Selecting the Signal Connectors and Cables
There are two signal input connectors: one VGA connector and
one DVI-I connector. The monitor will automatically determine
which inputs have valid video signals. The inputs can be selected
via the On-Screen Display (OSD) feature or by pressing the
Signal Input Selection control on the monitor front bezel.
The video mode supported by the DVI-I connector is
determined by the video cable used. For digital operation, use
the DVI-D to DVI-D signal cable provided. For analog operation,
a DVI-I to VGA signal cable must be attached to the DVI-I input
(not provided with the monitor).

Adjusting Screen Quality
Allow the monitor to warm up for 20 minutes before performing
the following procedures.
The Auto Adjustment feature automatically fine-tunes the image
quality each time a new video mode is utilized. If additional
improvement is desired, select the Auto Adjust control on the
front bezel.
For more precise adjustments, use the adjustment pattern
provided on the CD-ROM, and adjust the clock and phase
settings (accessed from the OSD menu) as described in the
following section.
Optimizing Digital Conversion
This monitor contains advanced circuitry that allows the flat
panel screen to function like a standard monitor. Two controls in
the on-screen display can be adjusted to improve image
performance: Clock and Clock Phase. Use these controls only
when the auto adjust function does not provide a satisfactory
image.
✎The Clock must first be set correctly since the Clock Phase
settings are dependent on the main Clock setting.
■Clock—Increase/decrease the value to minimize any vertical
bars or stripes visible on the screen background.
■Clock Phase—Increase/decrease the value to minimize video
distortion or video jitter.
✎When using the controls, you will obtain the best results by using
the adjustment pattern application provided on the CD-ROM.

distortion disappears. To restore the factory settings, select Yes
from the Factory Reset menu in the on-screen display.

Entering User Modes
The video controller signal may occasionally call for a mode that
is not preset if:
■You are not using a standard graphics adapter.
■You are not using a preset mode.
If this occurs, you may need to readjust the parameters of the
monitor screen by using the on-screen display. Your changes can
be made to any or all of these modes and saved in memory. The
monitor automatically stores the new setting, then recognizes the
new mode just as it does a preset mode. In addition to the 15
factory preset modes, there are four user modes that can be
entered and stored.

Energy Saver Feature
When the monitor is in its normal operating mode, the monitor
uses less than 60 watts of power and the Power light is green.
The monitor also supports a reduced power state. The reduced
power state will be entered into if the monitor detects the absence
of either the horizontal sync signal and/or the vertical sync signal.
Upon detecting the absence of these signals, the monitor screen is
blanked, the backlight is turned off, and the Power light is turned
amber. When the monitor is in the reduced power state, the
monitor will utilize less than 5 watts of power. There is a brief
warm up period before the monitor will return to its normal
operating mode.
Refer to your computer manual for instructions on setting energy
saver features (sometimes called power management features).
✎The above energy saver feature only works when connected to
computers that have energy saver features.
By selecting settings in the monitor’s Energy Saver utility, you
can also program the monitor to enter into the reduced power
state at a predetermined time. When the monitor’s Energy Saver
utility causes the monitor to enter the reduced power state, the
Power light blinks amber.
Care and Maintenance
Use the following guidelines to care for and maintain your
monitor during normal everyday use.
