To ensure safety, please read this manual carefully before 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. See Checking the safe distance between displays on page 6 for
details.
Notes on handling/transporting displays:
LCD video wall monitors have limited mechanical strength. To prevent the display from performance
failure caused by line defects, front bezel bending, glass scratch/broken, light leakage, etc.,
handle with care.
• At least two (2) adults are required to move & carry displays.
• 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
-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)

How to carry the product
At least two people are required to carry the display. When
carrying the product upright, please hold the handles on the rear
as well as the bottom of the display simultaneously for stability.
When carrying the product with the panel positioned upwards as
shown below, please hold as shown in the diagram.
5
Installation Precautions
A minor gap between monitors is strongly recommended
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. * Recommended gap between displays: 0.5mm -1.3mm
If the product needs to be set upright, hold both sides of the
product, and tilt backward carefully for. Do not let the panel to
touch the floor. If the product is tilted onto the bezel, the bottom of
the panel may be damaged.
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.
When laying down the product, lay a cushion on a flat floor. Put the
product on it with the panel the product facing down.
If there is not a cushion available, ensure the floor is clean and then
lay the product down carefully with the panel facing either upward
or downward. At this time, be careful for objects not to fall on the
panel.

Please secure minimum clearance as shown in the picture for adequate
ventilation and technical service.
Ventilation space in front of EK-Series displays must be furnished for heat
dispersion. If the area in front of EK-series displays must be sealed, there
must be consideration for the heat dispersion on the rear side of EK-series to
compensate.
During installation, do not apply pressure to any surface of
the panel. Damage to the panel may result from external pressure
or even minor impact to the panel. Physical and cosmetic damage
to displays is not covered under warranty.

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.
Dimensions below are minimum required for proper ventilation
Please ensure alignment on the Z-axis for a level plane across
adjacent panels (as shown in the diagram below). If precautions are
not heeded, GPO Display will not accept responsibility for any
Failure due to such installation errors.
Bottom of product: When resting panel on any surface
(padded table, floor), do not tilt panel forwards as shown in
the diagram below. The weight of the display applied in an
uneven manner can result in damage.
XX
Do not cover fan ventilation holes
Carefully install EK-series displays so as not to cover the fan air holes with any structural object.
If the holes are covered with anything, the inner temperature can be raised rapidly and it can cause malfunction.

GPO Display’s video wall displays have a built-in video wall processor that allows for virtually any matrix size of LCD video wall. In this
manual, instructions for a 2x2 configuration will be used as an example.
1. Installation
To install EK Series 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.
CAUTION: Never connect or disconnect cables from the display when the display is powered on as this may cause serious
damage.
2. Installation Requirement
2.1 Structure for the installation
Support structure 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 the following. 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 or e-mail [e-mail].
2.2 Power Requirements
Please refer to the specifications for power consumption of displays to be installed (Page 4)
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.
3. Heat Dissipation
Recommended LCD operational conditions are:
Temperature: 32°F -104°FHumidity: 20-80%
4. General Information
1.1 PC Settings:
PC’s need to be set to an appropriate graphics mode that has the same resolution with the panel to have clear screen image. And
the vertical refresh rate should be set to 56~75Hz, non–interlaced signal. The controller has been designed to take a very wide
range of input signals however to optimize the PC’s graphic performance we recommend choosing 60Hz vertical refresh rate: this will
prevent screen flicker. If you wish to view 4k2k@60Hz resolution, must use the PC that supported HDMI 2.0 (or DisplayPort 1.2).
1.2 Signal Quality:
Signal quality is very important: If there is noise or instability in the PC graphics output, this may result in visible noise on the
display. Refer to the graphic modes table in specification section for supported modes. Non-interlaced & interlaced video input is
acceptable. Please use the HDMI 2.0 dedicated cable. (4K2K@60Hz)
