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
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
and/or on the 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.
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.

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
Important safety information 3
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 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.

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 4 displays may be associated with a single media
player/computer (See the
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.

provided with the display for more detail). When multiple
The displays may be treated by an application as though there were up to 4 individual displays
connected to 4 graphic adaptor heads on the media player/computer.
The association of up to 4 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 4 (See the
User Guide
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.
for more detail).
Video Over Ethernet
Connecting the display 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.
