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.
WARNING: 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.
Å
Å
WARNING: 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.
User Guide

Safety and Maintenance Guidelines
CAUTION: For the protection of your monitor, as well as your
Ä
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.
■
■
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.
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.

an .INF (Information) file
an .ICM (Image Color Matching) file
Adobe Acrobat Reader is supplied on this CD and can be

The Information File
The .INF file enables the computer to communicate with the
monitor and use all the monitor features. The .INF file defines
monitor resources used by Microsoft Windows operating systems
to ensure monitor compatibility with the computer’s graphics
adapter.
This monitor is Windows Plug and Play compatible and the
monitor will work correctly without installing the .INF file.
Monitor Plug and Play compatibility requires that the computer’s
graphic card is VESA DDC2 compliant and that the monitor
connects directly to the graphics card. Plug and Play does not

distribution buffers/boxes. You may need to install the .INF file if
these conditions are not met.
The Image Color Matching File
The .ICM file provides accurate color representation. The .ICM
files are data files that are used in conjunction with graphics
programs to provide consistent color matching from monitor
screen to printer, or from scanner to monitor screen. The .ICM
file contains a monitor color system profile. This file is activated
from within graphics programs that support this feature.
The ICM color profile is written in accordance with the
International Color Consortium (ICC) Profile Format
specification.

sRGB Support
The monitor is designed to support sRGB for color management,
which adapts to the color standards used in the image technology
industry. Additional information on sRGB is available on
http://www.srgb.com/srgb.html (English only).
To take advantage of the sRGB support, you will need to change
your monitor’s color temperature to sRGB and install the sRGB
color profile (ICM) file.
The sRGB color temperature preset will improve the color
accuracy of sRGB images on the computer monitor, but some
color variation may still occur.

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

Energy Saver Feature
When the monitor is in its normal operating mode, the monitor
uses less than 40 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 2 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.

Power Cord Set Requirements
The monitor power supply is provided with Automatic Line
Switching (ALS). This feature allows the monitor to operate on
input voltages between 100-120V or 200-240V.
The power cord set (flexible cord or wall plug) received with the
monitor meets the requirements for use in the country where you
purchased the equipment.
If you need to obtain a power cord for a different country, you
should purchase a power cord that is approved for use in that
country.
The power cord must be rated for the product and for the voltage
and current marked on the product's electrical ratings label. The
voltage and current rating of the cord should be greater than the
voltage and current rating marked on the product. In addition, the
cross-sectional area of the wire must be a minimum of 0.75 mm²
or 18AWG, and the length of the cord must be between 6 feet
(1.8 m) and 12 feet (3.6 m). If you have questions about the type
of power cord to use, contact your HP authorized service
provider.
A power cord should be routed so that it is not likely to be walked
on or pinched by items placed upon it or against it. Particular
attention should be paid to the plug, electrical outlet, and the
point where the cord exits from the product.

LCD Monitor Quality
and Pixel Policy
The TFT monitor uses high-precision technology, manufactured
according to HP standards, to guarantee trouble-free
performance. Nevertheless, the display may have cosmetic
imperfections that appear as small bright or dark spots. This is
common to all LCD displays used in products supplied by all
vendors and is not specific to the HP LCD. These imperfections
are caused by one or more defective pixels or sub-pixels.
■
A pixel consists of one red, one green, and one blue
sub-pixel.
■
A defective whole pixel is always turned on (a bright spot on
a dark background), or it is always off (a dark spot on a bright
background). The first is the more visible of the two.
■
A defective sub-pixel (dot defect) is less visible than a
defective whole pixel and is small and only visible on a
specific background.
The HP display does not have more than:
■
■
■
■
3 bright dots.
5 dark dots.
5 total bright and dark dots.
No more than two adjacent (less than 25 mm edge-to-edge)
defective pixels.
User Guide
D–1
LCD Monitor Quality and Pixel Policy
To locate defective pixels, the monitor should be viewed under
normal operating conditions, in normal operating mode at a
supported resolution and refresh rate, from a distance of
approximately 50 cm (16 in.).
HP expects that, over time, the industry will continue to improve
its ability to produce LCDs with fewer cosmetic imperfections
and HP will adjust guidelines as improvements are made.
