							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 39 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 (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.

							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 stand, 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.
Unfolding the Monitor Pedestal Base
NOTE:The monitor is shipped with the base attached in a folded-flat position. To begin using the
monitor, you must unfold the base and place the monitor in an upright position.
1.Lift the monitor from its box and place it on a flat surface with the display head facing up.
2.Pivot the display head from portrait to landscape position (1).
Figure 3-1  Pivoting the Display Head
3.Press down on the rear hinge (2) while gently pulling up on the monitor display head (3).
4.Raise the monitor (4) to extend the pedestal base to the desired height.
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.

							Connecting the Signal and Power Cables
1.Place the monitor in a convenient, well-ventilated location near the computer.
2.Connect a VGA signal cable or DVI-D signal cable.
NOTE:The monitor is capable of supporting either analog or digital input. The video mode is
determined by the video cable used. The monitor will automatically determine which inputs have
valid video signals. The inputs can be selected by pressing the +/Input button on the front panel or
through the On-Screen Display (OSD) feature by pressing the Menu button.
●For analog operation, use the VGA signal cable provided. Connect the VGA signal cable to
the VGA connector on the rear of the monitor and the other end to the VGA connector on the
computer.
●For digital operation, use the DVI-D signal cable provided. Connect the DVI-D signal cable to
the DVI connector on the rear of the monitor and the other end to the DVI connector on the
computer.
3.Connect one end of the power cable to the AC power connector on the back of the monitor, and
the other end to an electrical wall outlet.
Figure 3-4  Connecting the Signal and Power Cables
WARNING!To reduce the risk of electric shock or damage to the 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 equipment 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

							Turning on the Monitor
1.Press the power button on the computer to turn it on.
2.Press the power button on the front of the monitor to turn it on.
CAUTION: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 the 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. Image retention is a condition that may occur on all LCD screens. Monitors
with a “burned-in image” are not covered under the HP warranty.
* A prolonged period of time is 12 consecutive hours of non-use.
NOTE:If pressing the power button has no effect, the Power Button Lockout feature may be enabled.
To disable this feature, press and hold the monitor power button for 10 seconds.
NOTE:You can disable the power LED in the OSD menu. Press the Menu button on the front of the
monitor, then select Management > Bezel Power LED > Off.
When the monitor is powered on, a Monitor Status message is displayed for five seconds. The message
shows which input (DVI or VGA) is the current active signal, the status of the auto-switch source setting
(On or Off), the default source signal, the current preset display resolution, and the recommended preset
display resolution.
The monitor automatically scans the signal inputs for an active input and uses that input for the display.
If two or more inputs are active, the monitor will display the default input source. You can change the
default source in the OSD by pressing the front panel menu button and selecting Source Control >
Default Source.
