Safety and Maintenance Guidelines  
CAUTION: For the protection of your monitor, as well as your  
Ä
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.

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. The .ICM  
file contains a monitor color system profile. This file is activated  
from within graphics programs that support this feature.  
The ICM color profile is written in accordance with the  
International Color Consortium (ICC) Profile Format  
specification.  
Installing the .INF and .ICM Files  
After you determine that you need to update, you can install the  
.INF and .ICM files from the CD or download them.

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 ten user modes that can be entered  
and stored.

Energy Saver Feature  
When the monitor is in its normal operating mode, the monitor  
uses less than 70 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 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.

Power Cord Set Requirements  
The monitor power supply is provided with Automatic Line  
Switching (ALS). This feature allows the monitor to operate on  
input voltages between 100-120V or 200-240V.  
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 mm²  
or 18AWG, and the length of the cord must be between 6 feet

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.  
The HP display does not have more than:  
3 bright dots.  
5 dark dots.  
5 total bright and dark dots.  
No more than two adjacent (less than 25 mm edge-to-edge)  
defective pixels.  
User Guide  
D–1  
 
   
LCD Monitor Quality and Pixel Policy  
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 (16 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.
