2 Safety and maintenance guidelines
Important safety information
A power cord is included with the display. If another cord is used, use only a power source and connection
appropriate for this display.
WARNING! To reduce the risk of electric shock or damage to the equipment:
• Do not disable the power cord grounding feature. The grounding plug is an important safety feature.
• Plug the power cord in a grounded (earthed) outlet that is easily accessible at all times.
• Disconnect power from the product by unplugging the power cord from the electrical outlet.
For your safety, do not place anything on power cords or cables. Arrange them so that no one can
accidentally step on or trip over them. Do not pull on a cord or cable. When unplugging from the electrical
outlet, grasp the cord by the plug.
To reduce the risk of serious injury, read the Safety and Comfort Guide. It describes proper workstation,
setup, posture, and health and work habits for computer users, and provides important electrical and
mechanical safety information. This guide is located on the Web at
documentation disc, if one is included with the display.
CAUTION: For the protection of the display, as well as the media player/computer, connect all power cords
for the media player/computer and its peripheral devices (such as a display, printer, scanner) to some form of
surge protection device such as a power strip or Uninterruptible Power Supply (UPS). Not all power strips
provide surge protection; the power strips must be specifically labeled as having this ability. Use a power
strip whose manufacturer offers a Damage Replacement Policy so you can replace the equipment, if surge
protection fails.
www.hp.com/ergo and/or on the
Use the appropriate and correctly sized furniture designed to properly support your display.
WARNING! Displays that are inappropriately situated on dressers, bookcases, shelves, desks, speakers,
chests, or carts can fall over and cause personal injury.
Care should be taken to route all cords and cables connected to the display so that they cannot be pulled,
grabbed, or tripped over.
CAUTION: Do not place the device in a location where water may drip and/or splash on the device.
Do not place an object that contains water, such as a flower vase, on the device.
Maintenance guidelines
To enhance the performance and extend the life of the display:
●
Do not open the display cabinet or attempt to service this product yourself. Adjust only those controls
that are covered in the operating instructions. If the display 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 display, as indicated on the label/back
plate of the display.
●
Be sure the total ampere rating of the products connected to the outlet does not exceed the current
rating of the electrical outlet, and the total ampere rating of the products connected to the cord does
Important safety information 3
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 display near an outlet that you can easily reach. Disconnect the display by grasping the plug
firmly and pulling it from the outlet. Never disconnect the display by pulling the cord.
●
Turn the display off when not in use. You can substantially increase the life expectancy of the display by
using a screen saver program and turning off the display when not in use.
CAUTION: Burn-in or image sticking might occur on displays which display the same static image on
the screen for prolonged periods of time. To avoid burn-in or image sticking and to prolong the life of
the display, you should activate one of the four ISM selections in the OSD, activate a screen-saver
application, periodically cycle between static information and moving images, or turn off the display
when it is not in use for prolonged periods of time.
●
Slots and openings in the cabinet are provided for ventilation. These openings must not be blocked or
covered. Never push objects of any kind into cabinet slots or other openings.
●
Do not drop the display 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 display in a well-ventilated area, away from excessive light, heat or moisture.
●
When removing the display base, you must lay the display face down on a soft area to prevent it from
getting scratched, defaced, or broken.
Cleaning the display
1. Turn off the display and unplug the power cord from the back of the unit.
2. Dust the display by wiping the screen and the cabinet with a soft, clean antistatic cloth.
3. For more difficult cleaning situations, use a 50/50 mix of water and Isopropyl alcohol.
CAUTION: 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 might seep behind the bezel and damage the electronics.
CAUTION: To clean the display screen or cabinet, do not use cleaners that contain any petroleum-based
materials such as benzene or thinner or any volatile substance. These chemicals might damage the display.

LAN/VOE connection
Connecting the display using LAN/VOE
▲
To connect the display to a network, plug your CAT-5 network cable into the Ethernet port.
The Ethernet cable from the display can connect to a media player/computer, a router (switch), or an
Intranet. A network connection enables the use of the Video Over Ethernet software to assign a media
player to drive the display. The connection also allows the HP Network Sign Manager program, running
on a networked media player/computer, to send command data.
Connect the Ethernet cable using one of the following connections:
●
Computer Direct Connection—Connect the LAN cable to the LAN port on the display and to the LAN
port on the media player/computer (1).
●
Router—Connect the LAN cable to the LAN port on the display and to a LAN port on the router (2).
●
Intranet—Connect the LAN cable to the LAN port on the display and to the Intranet network via an
access point (3).

Connecting multiple displays to one player
Multiple displays may be connected to a single media player/computer two different ways, using Video Over
Ethernet or using Tile Mode with VGA or DisplayPort video inputs.
Connecting multiple displays with Video Over Ethernet (VOE)
To connect multiple displays to a single media player/computer, each display must be connected to the same
sub-network as the media player/computer. The input source of each display must be set to VOE. With VOE,
displays are connected to media players/computer by establishing an association between the media player/
computer and one or more displays on the network with the VOE software that runs in the media player/
computer. Up to 12 displays may be associated with a single media player/computer (See the VOE Users
Guide provided with the display for more detail). When multiple displays are associated with a single media
player/computer, the displays may be mirrored (a single desktop image displays on all the displays
simultaneously).
The image may be extended across all the displays simultaneously using the View Span “Display Resolution”
dialog box.
The displays may be treated by an application as though there were up to 12 individual displays connected to
12 graphic adaptor heads on the media player/computer.
The association of up to 12 displays is the technical limit, and depending upon the complexity of the desktop
image to be displayed (playing flash, or streaming video), the number of displays which can be associated
with acceptable video performance may be less than 12 (See the Video Over Ethernet User Guide for more
detail).
Connecting multiple displays with Tile Mode
The recommended cable routing for daisy chain in Tile Mode is to start with the upper left display and
connect across the upper tier of displays going from left to right to the last display in that tier. Then cable
from the upper right display to the display just below it and connect across from right to left to the last
display on the left. Continue this back and forth, top to bottom cable route for all the tiers in the wall as
indicated in the next figure.
Connecting to a Digital Signage media player or computer 19
Multiple displays (up to 25 for DP and 6 for RGB/VGA) may be connected to a single media player/computer
using Tile Mode. Multiple displays in Tile Mode are only supported with either DisplayPort or VGA video input
sources. When connecting the multiple displays, the media player/computer is connected to the first display
only with either a DisplayPort or VGA connection. All the subsequent displays are connected to each other via
daisy chain using either the DP OUT connector from one display to the DP IN connector of the next display, or
using the VGA OUT connector from one display to the VGA IN connector of the next display. All displays must
be connected with the same video source, either DisplayPort or VGA. When using Tile mode to connect
multiple displays, only one desktop image may be displayed across all the tiled displays.
