							Entering User Modes
The video controller signal might occasionally call for a mode that is not preset if:
●You are not using a standard graphics adapter.
●You are not using a factory preset mode.
It this occurs, you might 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 factory preset modes and saved in memory.
The monitor automatically stores the new setting, then recognizes the new mode just like it does a
factory preset mode. Also there are at least ten user modes that can be entered and stored.

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 might have cosmetic imperfections that
appear as small bright or dark spots. This is common to all LCD monitor 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 in). 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 and pixel policy, refer to the HP Web site at:
www.hp.com/support. To find pixel policy information on the HP Web site, type in HP Pixel Policy in
the search box and press Enter.

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 products
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 18 AWG, and the length of the cord must be between 6 feet (1.8 m) and 12
feet (3.6 m). If you have questions about the type of power cord to use, contact an authorized HP
service provider.

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.
