• Turn the monitor off 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 AC 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 off 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 difficult 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 electronics. The
cloth should be moist, but not wet. Water dripping into the ventilation openings or other points of entry can
cause damage to the monitor. Allow the monitor to air-dry before use.
Shipping the monitor
Keep the original packing box in a storage area. You may need it later if you ship the monitor or move.

Preset display resolutions
The display resolutions listed below are the most commonly used modes and are set as factory defaults. This
monitor automatically recognizes these preset modes, and they will appear properly sized and centered on the
screen.
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 blanked, the backlight is turned off, 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: The above 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.

Accessibility
HP is working to weave diversity, inclusion and work/life into the fabric of our company, so it is reflected in
everything we do. Here are some examples of how we are putting differences to work to create an inclusive
environment focused on connecting people to the power of technology throughout the world.
Finding the technology tools you need
Technology can unleash your human potential. Assistive technology removes barriers and helps you create
independence at home, at work, and in the community. Assistive technology helps increase, maintain, and
improve the functional capabilities of electronic and information technology. For more information, see Finding
the best assistive technology on page 28.
Our commitment
HP is committed to providing products and services that are accessible for people with disabilities. This
commitment supports our company’s diversity objectives and helps us ensure that the benefits of technology
are available to all.
Our accessibility goal is to design, produce, and market products and services that can be effectively used by
everyone, including people with disabilities, either on a stand-alone basis or with appropriate assistive devices.
To achieve our goal, this Accessibility Policy establishes seven key objectives to guide our actions as a company.
All HP managers and employees are expected to support these objectives and their implementation in
accordance with their roles and responsibilities:
• Raise the level of awareness of accessibility issues within our company, and provide our employees with the
training they need to design, produce, market, and deliver accessible products and services.
• Develop accessibility guidelines for products and services, and hold product development groups
accountable for implementing these guidelines where competitively, technically, and economically feasible.
• Involve people with disabilities in the development of accessibility guidelines, and in the design and testing
of products and services.
• Document accessibility features and make information about our products and services publicly available in
an accessible form.
• Establish relationships with leading assistive technology and solution providers.
• Support internal and external research and development that will improve assistive technology relevant to
our products and services.
• Support and contribute to industry standards and guidelines for accessibility.
International Association of Accessibility Professionals (IAAP)
IAAP is a not-for-profit association focused on advancing the accessibility profession through networking,
education, and certification. The objective is to help accessibility professionals develop and advance their
careers and to better enable organizations to integrate accessibility into their products and infrastructure.
HP is a founding member, and we joined to participate with other organizations to advance the field of
accessibility. This commitment supports our company’s accessibility goal of designing, producing, and marketing
products and services that can be effectively used by people with disabilities.
IAAP will make our profession strong by globally connecting individuals, students, and organizations to learn
from one another. If you are interested in learning more, go to http://www.accessibilityassociation.org to join
the online community, sign up for newsletters, and learn about membership options.
Appendix B Accessibility 27
Finding the best assistive technology
Everyone, including people with disabilities or age-related limitations, should be able to communicate, express
themselves, and connect with the world using technology. HP is committed to increasing accessibility awareness
within HP and with our customers and partners. Whether it’s large fonts that are easy on the eyes, voice
recognition that lets you give your hands a rest, or any other assistive technology to help with your specific
situation—a variety of assistive technologies make HP products easier to use. How do you choose?
Assessing your needs
Technology can unleash your potential. Assistive technology removes barriers and helps you create
independence at home, at work, and in the community. Assistive technology (AT) helps increase, maintain, and
improve the functional capabilities of electronic and information technology.
You may choose from many AT products. Your AT assessment should allow you to evaluate several products,
answer your questions, and facilitate your selection of the best solution for your situation. You will find that
professionals qualified to do AT assessments come from many fields, including those licensed or certified in
physical therapy, occupational therapy, speech/language pathology, and other areas of expertise. Others, while
not certified or licensed, may also provide evaluation information. You will want to ask about the individual’s
experience, expertise, and fees to determine if they are appropriate for your needs.

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 specific to various types of technologies, as well
as performance-based requirements which focus on functional capabilities of covered products. Specific criteria
cover software applications and operating systems, web-based information and applications, computers,
telecommunications products, video and multi-media, 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 specifies 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
flexibility for innovation. WCAG 2.0 has also been approved as ISO/IEC 40500:2012.
WCAG specifically 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)

The Accessibility for Ontarians with Disabilities Act was established to develop and implement accessibility
standards to make goods, services, and facilities accessible to Ontarians with disabilities and to provide for the
involvement of persons with disabilities in the development of the accessibility standards. The first standard
of the AODA is the customer service standard; however, standards for transportation, employment, and
information and communication are also being developed. The AODA applies to the Government of Ontario, the
Legislative Assembly, every designated public sector organization, and to every other person or organization
that provides goods, services, or facilities to the public or other third parties and that has at least one employee
in Ontario; and accessibility measures must be implemented on or before January 1, 2025. For more information,
go to Accessibility for Ontarians with Disability Act (AODA).
