setting. Use these controls only when the auto-adjustment function does not provide a satisfactory
image.
●
Clock—Increases/decreases the value to minimize any vertical bars or stripes visible on the screen
background.
●
Clock Phase—Increases/decreases the value to minimize video distortion or video jitter.
NOTE: When using the controls, you will obtain the best results by using the auto-adjustment pattern

Using the HP Display Assistant Utility
HP Display Assistant, included on the software and documentation CD, is a software utility that guides
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.

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.
It 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 recognized the new mode just as it does a preset mode. In
addition to the factory preset modes, there are 15 (LA1905wg model), 20 (LA2205wg model), or 25
(LA2405wg model) 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 28.5 watts (LA1905wg
model), 31 watts (LA2205wg model), or 48.4 watts (LA2405wg model) 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 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.

Product Environmental Notices
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
displays resume operation when the user resumes use of the computer. Examples include the user
pressing the power/sleep button, receiving an input signal from an input device, receiving an input signal
from a network connection with the Wake On LAN (WOL) feature enabled, etc.
Additional information on the ENERGY STAR® program, its environmental benefits and the potential
energy and financial savings of the power management feature can be found on the EPA ENERGY
STAR Power Management Web site at

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.
