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
monitor, refer to the Power Cord Set Requirements section in Appendix C.
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 (earth) 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.
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.

Be sure the total ampererating of theproducts connected to the outlet doesnot exceed thecurrent
ratingoftheelectricaloutlet,andthetotalampererating of the products connectedtothe 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.
Slots and openings in thecabinet 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 pedestal 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 the computer.
2. Unplug the monitor from the wall outlet.
3. Clean the monitor plastics with a clean cloth dampened with water.
4. Clean the monitor screen with an antistatic screen cleaner.
CAUTION Do not use benzene, thinner, ammonia, or any other volatile substances to clean
the monitor or the screen. These chemicals may damage the cabinet finishas well as the screen.
Shipping the Monitor
Keep the original packing box in a storage area. You may need it later if you move or ship the monitor.

2. To mount the monitor to a swing arm, wall or other mounting fixture using the HP Quick Release,
follow the instructions provided in the documentation that comes with Quick Release.
Figure 3-12 Mounting the Monitor to a Swing Arm Using Quick Release
Figure 3-13 Mounting the Monitor to the Wall Using Quick Release
CAUTION The Quick Release is designed to support a maximum of up to 24 lbs. (10.9
kg). If you are mounting to a wall, HP recommends that you consult with a qualified
engineering, architectural, or construction professional to determine the appropriate type
and quantity of mounting fasteners required for the application and to ensure that the
mounting solution is properly installed to support applied loads.

3. If mounting the monitor using another manufacturer’s solution, use the screws (1) previously
removed from the monitor base to mount the display (2) to a swing arm or other mounting fixture.
Consult the documentation included with the mounting fixture for additional instructions.
CAUTION This monitor supports the VESA industry-standard 100mm mounting holes. To
attach a third-party mounting solution to the monitor, four 4mm, 0.7 pitch, and 10mm long
screws are required (not provided with the monitor). Longer screws should 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
Adobe Reader is supplied on this CD and can be installed from the menu.
NOTE If the monitor does not include a CD, the .INF and .ICM files can be downloaded from
the HP monitors support Web site. See Downloading from the Worldwide Web in this chapter.
The Information File
The.INFfiledefinesmonitorresourcesusedbyMicrosoftWindowsoperatingsystemstoensuremonitor
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 DDC2b-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. The .ICM file contains
a monitor color system profile. 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.
