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.

GPO Display Video Walls - Commercial Monitors - Digital Signage - Visual Solutions www.gpodisplay.com

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.

Chapter 1 Precautions

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

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

STEP 2

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)

Each display features four pegs located on its rear side.

Each of these pegs has a round, button-shaped knob

which fits into the openings in the H-Mounts. When

hanging a display in an H-Mount, ensure that the display is parallel to the H-Mount (not angled). This will help

ensure that all four pegs are inserted into each of the

four mount openings/insertion points.

Display Mounting (3x3 example)

STEP 3

Each display and its corresponding H-Mount has the

same width & height. When installing displays, note

that the service opening is positioned so that the

display outline will sit ~1.4” higher than the mount

outline when the pegs are aligned with the service

opening. Horizontal guide notches on the bottom

corners of the H-Mount frame help to guide the display

position during the mounting process, showing whether

the pegs are aligned with the openings/insertion points.

The bottom bezel of the display should align with the

horizontal notches during mounting.

*NOTE: Prior to installing displays, ensure cabling is

properly positioned, as shown on p. 18 of this manual.

Alignment: Z-Axis

Z-axis alignment can be adjusted by turning “Z-Bolts” at the rear of each corner of the display counter-clockwise.

This will push a given corner of a display outward from the wall, moving the corner of the display forward slightly.

Chapter 5 Alignment

Z-BOLT

Tip. Displays naturally tilt downward, meaning the top

protrudes slightly more than the bottom. In order to make Z-

Axis adjustments, push very gently with an open, gloved palm

on the top of the display and then engage the bottom Z-Bolts

by turning counter-clockwise.

STEP 1

Introducing alignment mechanisms

GPO Display Video Walls - Commercial Monitors - Digital Signage - Visual Solutions www.gpodisplay.com

Alignment: Y-Axis

Y-Axis alignment can be adjusted by turning the “Y-Knob” at the

bottom of the mount structure. A clockwise turn will raise the

bolt attached to the knob, which will raise one side of the display.

Conduct these adjustments in minor increments and exercise

caution when returning neighboring displays to their final,

installed position. Y-axis adjustments may lead to displays

“sitting” on top of displays below, causing excessive pressure on

bezels.

2) #1 : Using Y-Knob, raise both sides of display 1~2mm up if there is

no gap between bottom of #1 and #4

3) Slide #2 toward #1, checking Z-axis alignment. If alignment is poor,

adjust left Z-Bolts of #1 and right of Z-Bolts of #2 as needed.

Tip) Move #2 back to the left and compare its Z-bolts with the

backend of #1. The heads of #2’s Z-bolts should align with the back of

display #1. Slide #2 back toward

#1 (to the right) in its resting position. You may need to pull out on #2

slightly as you move it over to the right.

4) After making this adjustment, adjust #2’s Y- knobs to match level

with #1 (see p. 25 for more details on Y-Knob adjustments)

5) Follow the same steps on #3 with the directions reversed.

6) Move on to the next row of displays, substituting #4 for #1, #5 for

Precaution for Cables Connection of GPO Display’s Video Wall

 Digital noise may appear due to poor quality DVI cabling. If the video signal needs be delivered from a distance, electric noise must be accounted for. If the

distance is great or there is a serious noise issue, an optical fiber extender system is recommend over CAT-5/6 extension.

 Daisy-chaining can be initiated from any unit. There is no terminator at the end of the unit. It is strongly recommended that installers/customers record the

chaining diagram as it is crucial for diagnosis of issues, should they arise.

 Some installation sites have a high level of Electric Noise which may appear onscreen, especially with DVI.

 DVI, HDMI and DisplayPort are HDCP-compliant.

 Signal-looping specifications

Video signals should be boosted by using a distribution amplifier when more than four (4) units are connected via DVI (NSV & EN-series) or nine (9) units are

connected via HDMI (EK-series) -> See tables below

Connecting RS-232 Cables: Daisy-Chain Connection

 After mounting each display, insert any cables used for Power, video inputs or outputs into the set.

 Prior to mounting the next display, insert cables (including RS-232) from the outputs of the first display into the inputs of the second display.

 Repeat above steps for next display, if necessary.

 The RS-232 daisy chain limitation is listed as 20 displays, although theoretically more units can be accommodated. 25 displays was the

maximum number of units tested during production. While GPO Display can make no guarantees, RS-232 daisy-chaining should be able to take

place on up to 25 displays.

 Daisy-chaining can be initiated from any unit but it is strongly recommended that you start with a display on the bottom row for ease of

access. There is no terminator at the end of the unit. It is always recommended to record/make note of the chaining diagram as it is crucial to

determining issues with communication.

Connecting ACR (Auto Condition Reporting System)

NSV & EN-series (NSV for ACR Lite only)

 Install ACR Hub in an accessible location. This will ensure easy

access if the IR receiver must be accessed or if connectors must

be checked. This also ensures easy use of buttons on the ACR

Hub for SET ID selection and ON/OFF scheduling.

 Connect RS232 cable between ACR Hub and video wall monitor.

The ACR Hub will pass through serial commands sent to the

displays from a device residing upstream in the RS232 path.

 The ACR Hub serves as an IR extender for the remote controller.

ex) Users can power the video wall monitor ON/OFF  Must

change Set ID # on ACR Hub to “00” to address all sets

 Select Set ID “00” on the ACR Hub to address all displays

in the RS232 daisy-chain via remote controller.

 Users can toggle display Power On/Off via remote

control by pointing the remote controller at the IR

receiver at the front of the ACR Hub. The ACR Hub will

then send a command for Power On or Power Off to all

monitors.

 All other remote control functions are conducted in the

same manner as Power On/Off

 For more information, consult the ACR user manual.

Install ACR Hub in accessible

location
