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.

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.

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.

you through the tuning process with easy to understand instructions and background patterns designed  
for each monitor control. It provides:  
Accurate screen calibration through the use of step-by-step instruction Wizards to obtain the best  
overall image quality.  
Software control of the monitor image and color settings to eliminate dependence on the monitor’s  
front panel buttons and On-Screen Display (OSD) menu.  
Defined preset display settings for each individual user in a multi-user environment.  
Multiple preset display settings for a single user based on content and ambient lighting.  
Asset Management and Power Management capabilities that include remote control for individual  
or a group of displays on the domain from a centralized console application.  
The HP Display Assistant Utility has two modes of operation: Wizard and OSD mode. The preferred  
method of use is Wizard mode, which takes you through a step-by-step process to accurately calibrate  
the monitor. This method relies on a sequence of steps that will obtain the best display results when  
completed.  
NOTE: Refer to the HP Display Assistant user guide for additional information about the software.  
Identifying Monitor Conditions  
Special messages will appear on the monitor screen when identifying the following monitor conditions:  
Monitor Status—When the monitor is powered on or when the input source signal is changed, a  
Monitor Status message is displayed for five seconds. The message shows which input 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.  
Input Signal Out of Range—Change resolution setting to 1280 x 1024 – 60Hz—Indicates the  
monitor does not support the input signal because the resolution and/or refresh rate are set higher  
than the monitor supports.  
No Source Signal—Indicates the monitor is not receiving a video signal from the PC on the monitor  
video input connector. Check to determine if the PC or input signal source is off or in the power  
saving mode.

HP Display LiteSaver  
HP Display LiteSaver is a software application, available on the CD, that increases monitor life and  
saves energy. It allows you to place the monitor into its low power sleep mode at predefined times by  
shutting down or reducing power to most internal circuits. This helps protect the LCD panel against  
image retention. Image retention can occur when the monitor is left on while displaying the same image  
for an extended period of time, leaving a shadow of the image on the screen.

Energy Saver Feature  
When the monitor is in its normal operating mode, the monitor uses less than 33.5 watts 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 1 watt of power. There is a brief warm up period before the monitor will return to its normal  
operating mode.  
Refer to the computer manual for instructions on setting energy saver features (sometimes called power  
management features).  
NOTE: The above power saver feature only works when connected to computers that have energy  
saver features.  
By selecting the 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.

ENERGY STAR® Qualification  
HP Displays marked with the ENERGY STAR® certification mark meet the requirements of the U.S.  
Environmental Protection Agency (EPA) ENERGY STAR program. The EPA ENERGY STAR®  
certification mark does not imply endorsement by the EPA. As an ENERGY STAR Partner, Hewlett  
Packard Company has determined that this product meets the ENERGY STAR® program requirements  
for display energy efficiency.  
The following ENERGY STAR® certification mark appears on all ENERGY STAR qualified displays:  
The ENERGY STAR® program specifications for displays and computers were created by the EPA to  
promote energy efficiency and reduce air pollution through more energy-efficient equipment in homes,  
offices, and factories. One way products achieve this goal is by using the Microsoft Windows power  
management feature to reduce power consumption when the product is not in use.  
The power management feature enables the computer to initiate a low-power or “sleep” mode after a  
period of user inactivity. When used with an external ENERGY STAR® qualified display, this feature  
also supports similar power management features for the display. To take advantage of these potential  
energy savings, users should use the default power management settings that are provided with  
ENERGY STAR qualified computers and displays. The default power management settings on  
ENERGY STAR qualified computers are preset to behave in the following ways when the system is  
operating on AC power:  
Turn off an external display after 15 minutes of user inactivity  
Initiate a low power sleep mode for the computer after 30 minutes of user inactivity  
ENERGY STAR® qualified computers exit the low power sleep mode and ENERGY STAR qualified

D 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.  
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 (20  
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.
