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 on page 69.
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.
●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.
ENWW Maintenance Guidelines 3

supports both Speaker Out and Line Out, convert to Line Out using the card jumper of the program.
Refer to the manual that comes with the sound card for additional instructions.
ENWW Identifying Rear Components 11

Connecting to External Devices
Connecting to the Computer
1. Be sure the monitor, computer and all attached devices are turned off.
2. Connect the signal input cable:
a. For analog operation, connect the VGA (D-sub) signal cable to the RGB IN (1) connector on
the rear of the monitor and the other end to the VGA connector (2) on the computer.
NOTE: If connecting to a Mac computer, use the standard Macintosh adapter (3).
Figure 3-16 Connecting the VGA Signal Cable
b. For digital operation, connect the HDMI to DVI signal cable (not included) to the HDMI/DVI
(1) connector on the rear of the monitor and the other end to the DVI connector (2) on the
computer.
NOTE: Use shielded signal interface cables with ferrite cores to maintain standard
compliance for this product.
Figure 3-17 Connecting the HDMI to DVI Signal Cable
3. Connect the audio cable (sold separately) to the Audio (RGB/DVI) (1) connector on the rear of the
monitor and the other end to the line out jack (2) on the computer.
Figure 3-18 Connecting the Audio
NOTE: The ferrite core can be used to reduce electromagnetic waves when connecting an audio
cable. As shown in the image, fit the ferrite core to the audio cable. The ferrite core needs to be
separated from the mold by 5 centimeters.
