Chapter 1 Precautions
To ensure safety, please read this manual carefully prior to installation and follow the instructions
herein. Store this installation guide in a secure place for future reference.
The video wall must be installed on a flat and level surface which is strong enough to bear its weight.
Make sure mounting brackets are tightened and secured on the wall
The Liquid Crystal Display (LCD) panel of the display has a very thin protective layer of coating which is susceptible to
marking or scratching, and cracking if struck or pressured. Please cover and protect the displays if there is construction
or other work being conducted at the installation site.
Transport and handle displays by holding the handles on the back of the display. Do not touch the LCD panel surface
directly to avoid possible scratches and backlight leakage
Leave a slight (≥0.5mm) gap between displays in order to protect your LCD screens from the damage through the direct
transfer of weight.

Notes on handling/transporting displays
LCD video wall monitors have limited mechanical strength. To prevent
performance failure caused by line defects, front bezel bending, panel
scratch/breakage, light leakage, etc., displays must be handled with care.
Always have at least two (2) adults supporting the display when
moving/carrying.
Retain the original shipping box and packaging in storage for use in the
future, when you may need to transport the product.
When placing the display face (panel side) down:
Prepare a flat, level, horizontal surface that is larger than the
display and spread a thick protective sheet/foam on it. (Fig. 1) –
Lay the display down gently and horizontally.
When you want to place the display in an upright position:
Lift the display up horizontally by holding the two (2) handles at the
top/rear with one hand per person and supporting the bottom bezel
with the remaining hand. Do not allow the display to rest/put
weight on bezel edges and corners (Fig. 2)
Be careful not to scratch any parts of the display when placing the
display upright. (Fig. 3)
Stand the display vertically to make sure the its weight spread
evenly throughout the bottom bezel. Do not rest on corners or lean
forward/back. (Fig.4)

Chapter 1 Precautions

GPO Display Video Walls -Commercial Monitors -Digital Signage -Visual Solutions www.gpodisplay.com
A minor gap between monitors is required
High temperatures can cause slight expansion of panels. If there is no space
between panels, damage may occur as a result of pressure resulting from the
expansion of adjacent panels into one another. Please ensure that there is a
≥ 0.5mm gap between the displays. This can easily be checked by sliding a standard
business card between the gap (if there is no resistance, the gap is sufficient)
*Recommended gap
between displays: ≥ 0.5mm
Do not tilt displays in a manner that would result in
pressure on the panel edges. If backlight leakage (as
shown below) is evident, this is a sign of excessive
pressure and adjustment to the alignment of the array
must take place.
If more than 1kg of weight is applied to the top bezel of a panel (as
illustrated to the right), backlight leakage will result. This is a sign that
the panel alignment/angle must be adjusted or other countermeasures
must be applied.

Best practices for maintaining long-term quality
Keep temperature within 32°F ~ 104°F (Mandatory)
Follow Ventilation requirements
Keep panel usage under 20 hours per day in order to extend the stability and performance of the panel to longer than what is shown on the product
specification table.
Avoid displaying static images for prolonged periods of time.
Avoid content with significant brightness differences.
Dimensions below are minimum required for proper ventilation and movement of displays within H-Mount structure

2”
* Note:
Ventilation space must not be covered or closed off at the
front of the opening. If for some reason the opening
needs to be covered, other means of ventilation will need
to be incorporated into the design. Contact GPO Display
for design review and recommendations.

Structure for the installation
The structural design and construction for the display installation is the customer’s or its installer’s responsibility. GPO Display does not take
any responsibility on design or construction of installations. The minimum requirements for space, strength of the structure, electronic, heat
dissipation and environmental condition is described in this manual. If any further information or support is needed from GPO Display, please
contact us in advance to ensure ample time for support. We will be glad to help with any recommendations or information.
Call 510-659-9855 x1 or e-mail [e-mail].
Power Requirements
Please refer to the specifications for power consumption of displays to be installed. Do not plug more than two units into a given receptacle
(example: all displays in 2x2 should not be plugged into quad receptacle. Using more than 70% of current on the AC circuit is strongly
discouraged. Clean AC power is required for “noiseless” screen images. Avoid damages inflicted by power glitches or surges-either a power
conditioner or surge protector is recommended. Contact your electric power specialist for consultation.
Heat Dissipation Requirements
The range of LCD operational conditions are:
Temperature: 32°F ~104°FHumidity : 20 ~80%

To install GPO Display’s displays in video wall configuration, please read the installation directions carefully before
installation is performed. These monitors can be installed for single display ”standalone” operation, in a single row, or in
multiple rows. The highest Display Sequence number is 99. Contact GPO Display for arrays comprised of more than 99
displays. A 3x3 array will be used as an example in the following pages. Contact GPO Display if you are unsure about how to
apply these instructions and concepts to other video wall array configurations.
STEP 1
Verify that installation location is ready (power, network, wall reinforced, adequate ventilation, coax cable if being
installed)
Verify all necessary tools are ready to use.
Open all packages and lay everything out. Make sure all materials are present and there is no visible damage.
Note: RS-232 Cables must be daisy-chained for ease of service/firmware updating

Chapter 3 Mounts Installation
Affix first H-Mount to Wall or Wall Reinforcement frame with lag
screws (M4*20L). Measure carefully to ensure that the bracket
is located at the bottom/center of the array outline and that the
mount is level.
Use M8 interconnecting bolts & corresponding nuts to connect
the second mount and third mount to the first mount. Next,
affix second mount to Wall or Wall Reinforcement frame with
lag screws (M4*20L). Ensure that these mounts are level.
Tips for 2x2 or 3x3 video wall arrays
If your array is a 2x2 array (or 2x1, or 1x2), you may pre-assemble
mounts. For example, this means that you may use the M8
interconnecting bolts to construct a 2x2 frame prior to hanging the
mounts on the wall using The lag screws. This will help save time for
these smaller arrays. The mounts shown to the right are an older model
but the concept still applies to the current version of H-Mounts.
In a 3x3, you may assemble rows on the ground then attach to wall.
*Note: Floor surface must be level/even when connecting mounts.
Must connect mounts using M8 Bolts and nuts at all interconnection
positions (Long side: 14 positions, Short Side: 5 Positions)
