2 Safety and Maintenance Guidelines
Important Safety Information
A power cord is included with the 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 the
WARNING! To reduce the risk of electric shock or damage to the equipment:
• Do not disable the power cord grounding feature. The grounding plug is an important safety feature.
• Plug the power cord in a grounded (earthed) outlet that is easily accessible at all times.
• Disconnect power from the product by unplugging the power cord from the electrical outlet.
For your safety, 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.
To reduce the risk of serious injury, read the Safety and Comfort Guide. It describes proper
workstation, setup, posture, and health and work habits for computer users, and provides important
electrical and mechanical safety information. This guide is located on the Web at http://www.hp.com/
ergo and/or on the documentation CD, if one is included with the monitor.
CAUTION: For the protection of the monitor, as well as the computer, connect all power cords for
the 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 the
equipment, if surge protection fails.
Use the appropriate and correctly sized furniture designed to properly support your HP LCD monitor.
WARNING! LCD monitors that are inappropriately situated on dressers, bookcases, shelves, desks,
speakers, chests, or carts may fall over and cause personal injury.
Care should be taken to route all cords and cables connected to the LCD monitor so that they can not
be pulled, grabbed, or tripped over.
Maintenance Guidelines
To enhance the performance and extend the life of the monitor:
Do not open the monitor cabinet or attempt to service this product yourself. Adjust only those
controls that are covered in the operating instructions. If the monitor is not operating properly or
has been dropped or damaged, contact an authorized HP 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.
●

Chapter 2 Safety and Maintenance Guidelines
ENWW
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 the 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 the monitor off when not in use. You can substantially increase the life expectancy of the
monitor by using a screen saver program and turning off the monitor when not in use.
NOTE: Monitors with a “burned-in image” are not covered under the HP warranty.
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 the 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 the 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.
Cleaning the Monitor
1. Turn off the monitor and unplug the power cord from the back of the unit.
2. Dust the monitor by wiping the screen and the cabinet with a soft, clean antistatic cloth.
3. For more difficult cleaning situations, use a 50/50 mix of water and Isopropyl alcohol.
CAUTION: Spray the cleaner onto a cloth and use the damp cloth to gently wipe the screen surface.
Never spray the cleaner directly on the screen surface. It may run behind the bezel and damage the
electronics.
CAUTION: Do not use cleaners that contain any petroleum based materials such as benzene,
thinner, or any volatile substance to clean the monitor screen or cabinet. These chemicals may damage
the monitor.
Shipping the Monitor
Keep the original packing box in a storage area. You may need it later if you move or ship the
monitor.

3 Setting Up the Monitor
To set up the monitor, ensure that the power is turned off to the monitor, computer system, and other
attached devices, then follow the instructions below.
Attaching the Monitor Base
1. Set the base on a flat surface such as a table top.
2. Using both hands, position the pedestal over the base and press down firmly to lock it in place. Be
sure the base is securely locked in place and adjust the tilt angle to the desired position.
CAUTION: Do not touch the surface of the LCD panel. Pressure on the panel may cause non-
uniformity of color or disorientation of the liquid crystals. If this occurs the screen will not recover to its
normal condition.
Figure 3-1 Attaching the Base to the Monitor
NOTE: To remove the base, press inward on the tab in the center of the underside of the base and
pull the base from the pedestal.

Figure 3-9 Installing the Monitor on a Swing Arm
To attach the monitor to other mounting fixtures, follow the instructions included with the mounting
fixture to ensure that the monitor is safely attached.
CAUTION: This monitor supports the VESA industry standard 100 mm mounting holes. To
attach a third-party mounting solution to the monitor, four 4 mm, 0.7 pitch, and 10 mm long
screws are required. Longer screws must not be used because they may damage the monitor. It is
important to verify that the manufacturer’s mounting solution is compliant with the VESA standard
and is rated to support the weight of the monitor display panel. For best performance, it is
important to use the power and video cables provided with the monitor.

4 Operating the Monitor
Software and Utilities
The CD that comes with the monitor contains files you can install on the computer:
an .INF (Information) file
●
●
●
●
an .ICM (Image Color Matching) file
auto-adjustment pattern utility
additional software for the monitor model
NOTE: If the monitor does not include a CD, the .INF and .ICM files can be downloaded from the HP
The Information File
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 Microsoft 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 work through separate BNC type connectors or through distribution buffers/boxes.
The Image Color Matching File
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. This file is activated
from within graphics programs that support this feature.
NOTE: The ICM color profile is written in accordance with the International Color Consortium (ICC)
Profile Format specification.
