When Auto-Sleep Mode is enabled (enabled by default), the monitor enters a reduced power state when the
computer signals low power mode (absence of either horizontal or vertical sync signal).
Changing the Power Mode setting (select products only) 17

Upon entering this reduced power state (Auto-Sleep mode), the monitor screen is blanked, the backlight turns
o, and the power light turns amber. The monitor draws less than 0.5 W of power when in this reduced power
state. The monitor wakes from Auto-Sleep mode when the computer sends an active signal to the monitor
(for example, when you activate the mouse or keyboard).
To disable Auto-Sleep Mode in the OSD:
1. Press the center of the OSD controller to open the OSD.
2. In the OSD, select Power.
3. Select Auto-Sleep Mode, and then select O.
Using PiP and PbP (select products only)
The monitor supports both Picture in Picture (PiP), where one source is overlaid on another, and Picture
beside Picture (PbP), where one source is positioned adjacent to another either horizontally (for landscape
orientation) or vertically (for portrait orientation). Two full HD (FHD) images can be displayed in the PiP mode.
To use PiP or PbP:
1. Connect a secondary input source to the monitor.
2. Press the center of the OSD controller to open the OSD.
3. In the OSD, select Image, select PiP, and then select Enable PiP.
The monitor scans the secondary inputs for a valid signal input and uses that input for the PiP or PbP

6. If you want to adjust the position of the PiP, select PiP Position in the OSD, and then select the position
that you want.
Using low blue light mode (select products only)
Decreasing the blue light emitted by the monitor reduces the blue light exposure to your eyes. This monitor
uses a low blue light panel in default setting mode.
In the default setting mode, this monitor's low blue light panel is certied by TÜV to reduce blue light output
and create a more relaxing and less stimulating image while you read content on the screen.
DisplayPort multistreaming over DisplayPort (select models
only)
If you are using DisplayPort as the primary video input source, you can multistream to other DisplayPort
monitors connected in a daisy-chain conguration. You can connect up to four monitors in this conguration if
the graphics card in your computer supports this conguration.
The number of monitors you can connect through DisplayPort multistreaming depends on a number of
factors, including the resolutions and scan rates used for each monitor and the capabilities of your GPU or
embedded graphics system. If you have purchased a new graphics card for your computer, check the manual
that came with your graphics card for further information about its capabilities.
To multistream:
18 Chapter 2 Using the monitor

1. Be sure that DisplayPort is your primary video input.
2. Add a second monitor by connecting a DisplayPort cable between the DisplayPort OUT connector on the
primary monitor and the DisplayPort connector on a secondary monitor.
NOTE: You can connect up to four additional monitors. All but the nal monitor in the chain must
support DisplayPort multistreaming. For example when daisy-chaining four monitors, three of the four

4 Maintaining the monitor
Properly maintained, your monitor can run for many years. These instructions provide steps you can perform
to keep your monitor in the best condition.
Maintenance guidelines
Follow these instructions 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
Use these instructions to clean your monitor when necessary.
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 petroleum-based materials such as benzene, thinner, or
any volatile substance to clean the monitor screen or cabinet. These chemicals might damage the
monitor.
22 Chapter 4 Maintaining 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 can 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.
5. After you remove the dirt and debris, you can also clean the surfaces with a disinfectant. The World
Health Organization (WHO) recommends cleaning surfaces, followed by disinfection, as a best practice
for preventing the spread of viral respiratory illnesses and harmful bacteria. A disinfectant that is within
HP’s cleaning guidelines is an alcohol solution consisting of 70% isopropyl alcohol and 30% water. This
solution is also known as rubbing alcohol and is sold in most stores.
Shipping the monitor
Keep the original packing box in a storage area. You might need it later if you ship the monitor or move.

Energy saver feature
This monitor supports a reduced power state (power saver mode).
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. In the reduced power state, the monitor uses < 0.5 W
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.

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 specic 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 can 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 nd that
professionals qualied to do AT assessments come from many elds, including those licensed or certied in
physical therapy, occupational therapy, speech/language pathology, and other areas of expertise. Others,
while not certied or licensed, can 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
Countries worldwide are enacting regulations to improve access to products and services for persons with
disabilities. These regulations are historically applicable to telecommunications products and services, PCs
and printers with certain communications and video playback features, their associated user documentation,
and their customer support.
Standards
The US Access Board created Section 508 of the Federal Acquisition Regulation (FAR) standards 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 European Union created the EN 301 549 standard within Mandate 376 as an online toolkit for public
procurement of ICT products. The standard species the accessibility requirements applicable to ICT products
and services, with a description of the test procedures and evaluation methodology for each 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)
32 Appendix B Accessibility

● Understandable (by addressing readability, predictability, and input assistance)
● Robust (for instance, by addressing compatibility with assistive technologies)
