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 "Connecting the Power Cable" section  
on Chapter 3 .  
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, book  
cases, 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.  
Safety Precautions  
•
Use only a power source and connection compatible with 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 power cord does not exceed the rating of the power  
cord. Look on the power label to determine the ampere rating (Amps or A) for  
each device.

Selecting Video Input Connectors  
The input connectors are:  
•
•
VGA connector (analog)  
DVI-D connector (digital)  
The monitor automatically determines which inputs have valid video signals, and  
displays the image.  
You can connect the VGA cable, the DVI-D cable, or both. If both cables are installed,  
the default input selection is DVI.The source of input can be switched using the Input  
Select option in the OSD menu.  
Identifying Monitor Conditions  
Special messages appear on the monitor screen for the following monitor conditions:  
Input Signal Out of Range - When the Hsync Frequency, Vsync Frequency or  
Resolution is out of the monitor support range, The monitor will show this message.  
No Signal - When the video cable is not connected, or the video cable is connected  
but there is no active signal input, the monitor will show this message, after 9 seconds  
the monitor will enter power saving. This message location is at the position setting in  
"OSD Setup" item.  
Auto Adjustment in Progress - Indicates the auto adjustment function is active. See  
"Adjusting Screen Quality" in this chapter.  
Adjusting Screen Quality  
The auto adjustment feature automatically fine-tunes the image quality for display  
size, position, clock, and phase each time a new video mode is displayed. For more  
precise adjustments of VGA input, run the Auto Adjustment software on the CD. If you  
want additional image quality improvement, use the Clock and Phase controls of the  
monitor to fine tune the image. See "Optimizing Analog Video" in this chapter.  
Optimizing Analog Video  
Some monitors contain advanced circuitry that allow the monitor to function as a  
standard analog monitor. Two controls in the OSD menu can be adjusted to improve  
analog image performance:  
Clock - Increase or decrease the value to minimize any vertical bars or stripes visible  
on the screen background.  
Phase - Increase or decrease the value to minimize video distortion or video jitter.  
Use these controls only when the auto adjustment function does not provide a  
satisfactory monitor image in analog mode. To obtain the best results:  
1. Allow the monitor to warm up for 30 minutes before adjusting.  
2. Access the OSD menu, then select Image Setup.  
3. Set the main Clock settings correctly first, because the Phase settings depend on  
the main Clock settings.When adjusting the Clock and Phase values, if the  
monitor images become distorted,continue adjusting the values until the distortion  
disappears. To restore the factory settings, access the OSD menu, select Factory  
Reset , and then select Yes .

Power-Saver Feature  
When the monitor is in normal operating mode, the Power light is blue and the monitor  
uses the normal watts of power. For power usage, refer to "Technical Specification"  
(Appendix B). The monitor also supports a power-saver mode that is controlled by the  
computer. When the monitor is in the reduced-power state, the monitor screen is  
blank, the backlight is off, and the Power light is amber. The monitor uses minimum  
power. When the monitor is "awakened," a brief warm-up period occurs before the  
monitor returns to normal operating mode. The energy-saving reduced power state  
activates if the monitor does not detect either the horizontal sync signal or the vertical  
sync signal. The power-saver feature must be activated on your computer for this  
feature to work. Refer to your computer documentation for instructions on setting  
energy-saver features (sometimes called power-management features).  
NOTE: The energy-saver feature works only when the monitor is connected to  
computers that have energy-saver features.

LCD Monitor Quality and Pixel Policy  
Your LCD Monitor uses high-precision technology, manufactured according to high  
standards, to help 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 your LCD Monitor. These imperfections are caused by one or more  
defective pixels or subpixels.  
A pixel consists of one red, one green, and one blue subpixel. 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  
subpixel (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 and in normal operating mode at a supported resolution and refresh rate,  
from a distance of approximately 50 cm (16 inches). We expect that, over time, the  
industry will continue to improve its ability to produce displays with fewer cosmetic  
imperfections, and we will adjust guidelines as improvements are made. For more  
information about your LCD Monitor, refer to the HP Web site at:
