HP Watermark and Image Retention Policy
The IPS monitor models are designed with IPS (In-Plane Switching) display technology which
provides ultra-wide viewing angles and advanced image quality. IPS monitors are suitable for a wide
variety of advanced image quality applications. This panel technology, however, is not suitable for
applications that exhibit static, stationary or fixed images for long periods of time without the use of
screen savers. These types of applications may include camera surveillance, video games, marketing
logos, and templates that are displayed on the screen for a prolonged period of time. Static images
may cause image retention damage that could look like stains or watermarks on the monitor's screen.
Monitors in use for 24 hours per day that result in image retention damage are not covered under the
HP warranty. To avoid image retention damage, always turn off the monitor when it is not in use or
use the power management setting, if supported on your system, to turn off the display when the
system is idle.

monitor you are configuring
4. After setting the DisplayPort Compatibility Mode in the OSD, use the computer operating
system's display settings to set the display mode for the secondary monitor to either mirror the
image of the primary display or extend the second display for a different image from the primary
display.
If you wish to connect additional monitors downstream (up to four maximum), all but the final monitor
in the chain must support DisplayPort multstreaming.
28 Chapter 4 Operating the Monitor
Connect from the DisplayPort OUT of one monitor to the DisplayPort IN of the next, until you have the
desired number of displays.
If you want different information on each screen be sure that all upstream monitors are configured to

Color Management
The monitor includes both standard and user definable color space settings to support a variety of
customer uses. Most color spaces are pre-calibrated at the factory and can be recalibrated by the end
user when the HP DreamColor Calibration Solution kit is used (sold separately). Calibration includes
control of the monitor’s color gamut, RGB primaries, gamma, and luminance. The RGB Adjust color
selections are not calibrated and cannot be calibrated.

Color Calibration — Factory
Three standard color spaces, sRGB, AdobeRGB, and BT.709, are calibrated at the factory and a one-
page calibration report is printed and included in each monitor carton.
Native color space is configured at the factory to provide the maximum panel luminance.
The default setting for the User color space is the same as Native.
Factory calibration settings are saved in monitor memory and can be re-applied at any time through
the On-Screen Display.
Color Calibration — User
With the exception of the native panel color space, each color space can be calibrated by the end
user with the user calibration software that comes with the product and with a colorimeter device (the
colorimeter is included in the DreamColor Calibration Solution option kit, sold separately). The user
36 Chapter 4 Operating the Monitor
calibration software is a Windows-based application that requires use of the Windows 7 or later
operating system. The calibration process uses the following steps:
1. Insert the monitor documentation disc into the host computer’s CD/DVD player.
2. Install the user calibration program on the host computer.
3. Place the colorimeter from the DreamColor Calibration Solutions kit in front of the monitor panel
as directed.
4. Run the calibration software and follow the on-screen steps. One color space can be calibrated
and named at a time. Two methods of calibration are possible:
●
Wizard mode – the application will ask questions about the user’s environment and usage
then will suggest settings to be used.
●
Expert mode – the user will be asked to input all the variables intended for use in the
calibration process.
When calibration is complete, the values are saved in monitor memory. The most recent calibration
settings can be re-applied at any time through the On-Screen Display.
Auto EDID Update
By default, the display automatically updates the display EDID when you switch color spaces.
If Auto EDID Update is enabled, the EDID will be updated for all inputs every time you change the
active color space preset. If Auto EDID Update is disabled, each input will be set to the factory default
values for the Native color space.
You can enable or disable Auto EDID Update in the OSD:
1. Press any of the five front bezel buttons on the right side of the front bezel to activate the
buttons.
2. Press the bottom Open Menu button to open the OSD.
3. In the OSD, select Management > Auto EDID Update and then select either Enable or
Disable.

Product Environmental Notices
ENERGY STAR® Qualification
As an ENERGY STAR® Partner, Hewlett Packard Company has followed the EPA's enhanced
product qualification and certification process to ensure that the products marked with the ENERGY
STAR® logo are ENERGY STAR® qualified per the applicable ENERGY STAR® guidelines for
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

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.
