HP watermark and image retention policy
The IPS monitor models are designed with In-Plane Switching (IPS) 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 xed 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. Static images
may cause image retention damage that could look like stains or watermarks on the monitor’s screen.
Image retention damage on monitors that are in use 24 hours per day is not covered under the HP warranty.
To avoid image retention damage, always turn o the monitor when it is not in use or use the power
management setting, if supported on your system, to turn o the monitor when the system is idle.

4 Maintaining the monitor
Maintenance guidelines
To enhance the performance and extend the life of the monitor:
●Do not open the monitor cabinet or attempt to service this product yourself. Adjust only those controls
that are covered in the operating instructions. If the monitor is not operating properly or has been
dropped or damaged, contact an authorized HP dealer, reseller, or service provider.
●Use only a power source and connection appropriate for this monitor, as indicated on the label or back
plate of the monitor.
●Be sure that the total ampere rating of the products connected to the outlet does not exceed the current
rating of the AC outlet and that 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 the monitor near an outlet that you can easily reach. Disconnect the monitor by grasping the plug
rmly and pulling it from the outlet. Never disconnect the monitor by pulling the cord.
●Turn the monitor o when it is not in use and use a screen saver program. Doing this can substantially
increase the life expectancy of the monitor.
NOTE: A burned-in image on the monitor is not covered under the HP warranty.
●Never block the slots and openings of the cabinet or push objects into them. These openings provide
ventilation.
●Do not drop the monitor or place it on an unstable surface.
●Do not allow anything to rest on the power cord. Do not walk on the cord.
●Keep the monitor in a well-ventilated area, away from excessive light, heat, or moisture.
Cleaning the monitor
1. Turn o the monitor and unplug the power cord from the AC outlet.
2. Disconnect any external devices.
3. Dust the monitor by wiping the screen and the cabinet with a soft, clean antistatic cloth.
4. For more diicult cleaning situations, use a 50/50 mix of water and isopropyl alcohol.
IMPORTANT: Do not use cleaners that contain any petroleum-based materials such as benzene,
thinner, or any volatile substance to clean the monitor screen or cabinet. These chemicals may damage
the monitor.
IMPORTANT: Spray the cleaner onto a cloth and use the damp cloth to gently wipe the screen surface.
Never spray the cleaner directly on the screen surface. It may run behind the bezel and damage the

Energy saver feature
The monitor supports a reduced power state. The reduced power state is initiated if the monitor detects the
absence of either the horizontal sync signal or the vertical sync signal. Upon detecting the absence of these
signals, the monitor screen is blank, the backlight is turned o, and the power light turns amber. When the
monitor is in the reduced power state, the monitor uses < 0.5 watts of power. There is a brief warm-up period
before the monitor returns to its normal operating state.
See the computer manual for instructions on setting the energy saver mode (sometimes called power
management feature).
NOTE: This power saver feature works only when the monitor is connected to a computer that has energy
saver features.
By selecting the settings in the monitor Sleep Timer utility, you can also program the monitor to initiate the
reduced power state at a predetermined time. When the monitor Sleep Timer utility initiates the reduced
power state, the power light blinks amber.

Standards and legislation
Standards
Section 508 of the Federal Acquisition Regulation (FAR) standards was created by the US Access Board to
address access to information and communication technology (ICT) for people with physical, sensory, or
cognitive disabilities. The standards contain technical criteria specic to various types of technologies, as well
as performance-based requirements which focus on functional capabilities of covered products. Specic
criteria cover software applications and operating systems, web-based information and applications,
computers, telecommunications products, video and multimedia, and self-contained closed products.
Mandate 376 – EN 301 549
The EN 301 549 standard was created by the European Union within Mandate 376 as the basis for an online
toolkit for public procurement of ICT products. The standard species the functional accessibility
requirements applicable to ICT products and services, together with a description of the test procedures and
evaluation methodology for each accessibility requirement.
Web Content Accessibility Guidelines (WCAG)
Web Content Accessibility Guidelines (WCAG) from the W3C's Web Accessibility Initiative (WAI) helps web
designers and developers create sites that better meet the needs of people with disabilities or age-related
limitations. WCAG advances accessibility across the full range of web content (text, images, audio, and video)
and web applications. WCAG can be precisely tested, is easy to understand and use, and allows web
developers exibility for innovation. WCAG 2.0 has also been approved as ISO/IEC 40500:2012.
WCAG specically addresses barriers to accessing the web experienced by people with visual, auditory,
physical, cognitive, and neurological disabilities, and by older web users with accessibility needs. WCAG 2.0
provides characteristics of accessible content:
●Perceivable (for instance, by addressing text alternatives for images, captions for audio, adaptability of
presentation, and color contrast)
●Operable (by addressing keyboard access, color contrast, timing of input, seizure avoidance, and
navigability)
●Understandable (by addressing readability, predictability, and input assistance)
●Robust (for instance, by addressing compatibility with assistive technologies)
