Safety and Maintenance Guidelines
Important Safety Information
A power cord is included with your 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 your monitor, refer to the Power Cord Set Requirements section in Appendix C.
WARNING: To reduce the risk of electric shock or damage to your equipment, do not disable the power cord grounding feature. This equipment is designed to be connected to a grounded (earthed) power outlet that is easily accessible to the operator. The grounding plug is an important safety feature.
WARNING: For your safety, be sure that the power outlet you plug the power cord into is easily accessible and located as close to the equipment as possible. When you need to disconnect the power to the equipment, unplug the power cord from the power outlet by grasping the plug firmly. Never pull on the cord.
CAUTION: For the protection of your monitor, as well as your computer, connect all power cords for your 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 your equipment if surge protection fails.

Maintenance Guidelines

To enhance the performance and extend the life of your monitor:
Do not open your monitor cabinet or attempt to service this
product yourself. Adjust only those controls that are covered in the operating instructions. If your monitor is not operating properly or has been dropped or damaged, contact your HP authorized 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 your 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 your monitor off when not in use. You can substantially
increase the life expectancy of your monitor by using a screen saver program and turning off the monitor when not in use.
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 your 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 your 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 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 your monitor or the screen. These chemicals may damage the cabinet finish as 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 your monitor.

Selecting the Signal Connectors and Cables
There are two signal input connectors:
VGA connector DVI-I connector (available on select models)
The monitor will automatically determine which inputs have valid video signals. The inputs can be selected through the On-Screen Display (OSD) feature or by pressing the button (to enable DVI signal input) or the + button (to enable VGA signal input) on the monitor front bezel. The video mode supported by the DVI-I connector is determined by the video cable used. For digital operation, use the DVI-D signal cable provided. For analog operation, use the VGA signal cable or VGA to DVI-I signal cable provided.

Connecting the Monitor

1. Place the monitor in a convenient, well-ventilated location near your computer.

2. For analog operation,

connect one end of the VGA signal cable to the VGA
connector on the monitor and the other end to the VGA connector on the computer, or
connect one end of the VGA-to-DVI signal cable to the
DVI connector on the monitor and the other end to the VGA connector on the computer. For digital operation (available on select models), use the DVI-D signal cable. These cables are provided with the monitor.
Connecting the VGA Signal Cable
CAUTION: The DVI-D cable supplied with this monitor is for digital-to-digital connection only. Your computer must have a DVI-compatible graphics card installed for use with this cable. When connecting the DVI-D signal cable to the DVI connector on the monitor (available on select models), you must connect the other end of the DVI-D cable to the DVI connector on the computer.

3. Connect the USB cable to the USB upsteam connector on the monitor and to a convenient USB connector on the computer.

Connecting the USB Cable

4. If ready, connect the USB devices to the USB downstream connectors on the monitor.

Connecting USB Devices

5. Connect one end of the power cable to the back of the monitor, and the other end to an electrical wall outlet.
WARNING: To reduce the risk of electric shock or damage to your 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 monitor by unplugging the power cord from the electrical outlet. 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.

Entering User Modes

The video controller signal may occasionally call for a mode that is not preset if:

You are not using a standard graphics adapter. You are not using a preset mode.
If this occurs, you may need to readjust the parameters of the monitor screen by using the on-screen display. Your changes can be made to any or all of these modes and saved in memory. The monitor automatically stores the new setting, then recognizes the new mode just as it does a preset mode. In addition to the 15 factory preset modes, there are four user modes that can be entered and stored.

User Guide B5

Energy Saver Feature
When the monitor is in its normal operating mode, the monitor uses less than 40 watts of power 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 2 watts of power. There is a brief warm up period before the monitor will return to its normal operating mode. Refer to your computer manual for instructions on setting energy saver features (sometimes called power management features).
The above energy saver feature only works when connected to computers that have energy saver features.
By selecting settings in the monitors Energy Saver utility, you can also program the monitor to enter into the reduced power state at a predetermined time. When the monitors Energy Saver utility causes the monitor to enter the reduced power state, the Power light blinks amber.

The power cord set (flexible cord or wall plug) received with the monitor meets the requirements for use in the country where you purchased the equipment. If you need to obtain a power cord for a different country, you should purchase a power cord that is approved for use in that country. The power cord must be rated for the product and for the voltage and current marked on the product's electrical ratings label. The voltage and current rating of the cord should be greater than the voltage and current rating marked on the product. In addition, the cross-sectional area of the wire must be a minimum of 0.75 mm or 18AWG, and the length of the cord must be between 6 feet (1.8 m) and 12 feet (3.6 m).
