Safety and Maintenance
Guidelines
Important Safety Information
A power cord is included with your monitor. If another cord is
used, use only a power source and connection appropriate for this
monitor. For information on the correct power cord set to use with
your monitor, refer to the “Power Cord Set Requirements” section
in Appendix C.
ÅWARNING: To reduce the risk of electric shock or damage to your
equipment, do not disable the power cord grounding feature. This
equipment is designed to be connected to a grounded (earthed)
power outlet that is easily accessible to the operator. The grounding
plug is an important safety feature.
ÅWARNING: For your safety, be sure that the power outlet you plug
the power cord into is easily accessible and located as close to the
equipment as possible. When you need to disconnect the power to
the equipment, unplug the power cord from the power outlet by
grasping the plug firmly. Never pull on the cord.

2–2 User’s Guide
Safety and Maintenance Guidelines
ÄCAUTION: For the protection of your monitor, as well as your
computer, connect all power cords for your computer and its
peripheral devices (such as a monitor, printer, scanner) to some form
of surge protection device such as a power strip or Uninterruptible
Power Supply (UPS). Not all power strips provide surge protection;
the power strips must be specifically labeled as having this ability.
Use a power strip whose manufacturer offers a Damage Replacement
Policy so you can replace your equipment if surge protection fails.
Maintenance Guidelines
To enhance the performance and extend the life of your monitor:
■Do not open your monitor cabinet or attempt to service this
product yourself. Adjust only those controls that are covered
in the operating instructions. If your monitor is not operating
properly or has been dropped or damaged, contact your HP
authorized dealer, reseller, or service provider.
■Adjust only those controls that are discussed in the operating
instructions.
■Use only a power source and connection appropriate for this
monitor, as indicated on the label/back plate of the monitor.
■Be sure the total ampere rating of the products connected to
the outlet does not exceed the current rating of the electrical
outlet, and the total ampere rating of the products connected
to the cord does not exceed the rating of the cord. Look on the
power label to determine the ampere rating (AMPS or A) for
each device.
■Install your monitor near an outlet that you can easily reach.
Disconnect the monitor by grasping the plug firmly and
pulling it from the outlet. Never disconnect the monitor by
pulling the cord.

Safety and Maintenance Guidelines
User’s Guide 2–3
■Turn your monitor off when not in use. You can substantially
increase the life expectancy of your monitor by using a screen
saver program and turning off the monitor when not in use.
■Unplug your monitor from the wall outlet before cleaning.
Do not use liquid cleaners or aerosol cleaners. Use a damp
cloth for cleaning. If the screen requires additional cleaning,
use an antistatic screen cleaner.
ÄCAUTION: Do not use benzene, thinner, ammonia, or any other
volatile substances to clean your monitor or the screen. These
chemicals may damage the cabinet finish as well as the screen.
■Slots and openings in the cabinet are provided for ventilation.
These openings must not be blocked or covered. Never push
objects of any kind into cabinet slots or other openings.
■Do not drop your monitor or place it on an unstable surface.
■Do not allow anything to rest on the power cord. Do not walk
on the cord.
■Keep your monitor in a well-ventilated area, away from
excessive light, heat or moisture.
■When removing the monitor base, you must lay the monitor
face down on a soft area to prevent it from getting scratched,
defaced, or broken.

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
through the On-Screen Display (OSD) feature or by pressing the
Signal Input 1 or 2 buttons 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-A to VGA signal cable must be attached to the DVI-I input
(not provided with the monitor).

Operating the Monitor
Installing the Information Files
The CD-ROM included with this monitor contains two
information files to be installed onto your computer; an .INF file
and an .ICM file.
■The .INF file defines monitor resources and provides
specifications used by most operating systems to install
support software for certain hardware devices. The .INF file
ensures monitor compatibility and optimization with your
computer’s graphics adapter. INF files are also downloadable
by clicking on: http://www.hp.com/go/support and selecting the
desired monitor.
■The .ICM file provides color matching consistency from
monitor screen to printer and is activated from within
graphics programs that have this feature.
To install these files on your computer, insert the Software and
Reference Library CD in your computer CD-ROM drive. When
the CD menu launches, select “Install INF and ICM Files” and
follow the on-screen instructions.
