Introduction
The WN- 5220-S VideoWall is a mult i- frequency, multi-source display capable
of displaying a wide range of video sources. The clear, bright image is a
product of careful engineering and optical innovation. Setup is easy because of
light weight and simple mechanical connections. And it is fast because there
are only a few adjustments necessary to configure the image.
Product Introduction
The optional Ultra-Thin Mullion screen gives the display additional flexibility in
meeting the most demanding image quality applications. By eliminating t he
front-surf ace frame, this screen nearly eliminates the visible seam between the
displays. (Mullion: the metal edge around the screen.)
Clarity’s Big Picture™ option is a built-in data/videowall processor. Without the
need for an external processor, Big Pict ur e can scale t he source video to
accommodate any display wall size up to four high and four wide.
Features
Clarity’s products are designed and developed by experts in LCD projection
technology and offer sig nificant advantages over conventional cathode ray
tube (CRT) based systems including:

Make sure the power cord is compatible with the nominal power
source used with the WN-5220-S display.
Power Consumption
Power consumption of the WN-5220-S is 920 Watts, or approximately
8 Amps current draw at 115 VAC (4 Amps at 230 VAC). The
WN-5220-S can be configured to operate on either 90-130 VAC or
180-260 VAC nominal power sources at 50/60 Hz.
Voltage Range
The operating voltage rang e of the W N- 5220- S is set via a switch on
the power supply near the AC power plug and on/off switch.
Operation of the display at the incorr ect voltage level can cause
damage to the unit which is not covered by the warranty.
!"Select the setting labeled 115V if your power source is
between 100 and 120 Volts AC.
!"Select the setting labeled 230V if your power source is
between 200 and 240 Volts AC.
If the input voltage drops below approximately 90V (175V if the
WN-5220-S is set to the 230V setting) the display will automatically
shut down to protect itself.

WN-5220-S VideoWall User’s Guide
On a typical 20A, 115V circuit, no more than t wo WN-5220-S displays
may be installed. This allows an extra current marg in. If any circuit
used to power one or more W N- 5220- S displays is not a dedicated
circuit, the additional electrical load placed on the cir cuit by other
equipment must be considered.
WARNING
Displays that are intended for 240V configuration must have a
properly rated power supply cord and attachment plug supplied
by the installer.
WARNING
If extension cords are used for power, use only 3-prong
grounded cords sized to handle system power requirements.
Using the wrong-size extension cord can cause a fire-safety
hazard and can reduce the voltage available to the
WN-5220-S. If the extension cord is warm to the touch it is t oo
small and should be immediately removed from operation.
Temperature and Humidity
The WN- 5220- S is designed to operate over an ambient temperatur e
range of 0° to 35° C (32° to 95° F) and a humidity of 20 to 80 % R.H.
non-condensing.
Some types of environmental lighting , such as incandescent, or high
intensity discharge lamps such as metal halide or mer cur y vapor
lamps, create high temperatur es and t his can cause excessive
heating of the WN-5220-S. Displays should be positioned far enough
away from high-temperature lights to prevent heat buildup.
Nearby heat sources can cause high operating temper at ur es in the
WN-5220-S display. Minimize the display’s exposure to heating ducts,
radiators, or other external heat sources.
Flooring
A single WN- 5220- S display unit weighs appr oximat ely 120 lbs (55
kg). Befor e inst alling the WN- 5220- S, determine the structural
integrity of the flooring where it will be used. The floor should be level
and strong enough to support the combined weight of the number of
displays and other equipment used in the installation. Take special
care when installing a WN- 5220-S in a wall configuration on a
temporary structure such as a stage floor, where the flooring could
bend or collapse under the weight of the installat ion. Never st ack
more than four (4) WN-5220-S displays vertically on a tempor ar y
floor.

Clarity Visual Systems
Clearance
Normal maintenance, such as lamp module and air filter replacement,
can be performed from the front or rear of the WN-5220-S. Maintain
sufficient clearance to allow easy access from t he front. A minimum of
4 feet is recommended. For full maintenance from the r ear , the
minimum recommended clearance is 3 feet .
To allow proper cooling, the minimum required clearance to the rear
of the display should be 6 inches. The minimum required clearance to
the top at the front of the unit is 6 inches. See Environmental
Specifications on page 97 for cooling requirements.
If installed in a video wall configuration, a m inim um of 12 inches to
the ceiling from the t op of the highest display is needed if the unit s
are installed from the front.
Cooling
Regardless of clearances and the gener al am bient temperature, the
most important fact or t hat affects reliable operat ion is t he temperature
and quantity of air coming int o the display. The intake air temperature
at the air filter must not exceed 95° F (35° C). If there is any doubt
about this temperature in an installat ion, r un t he displays for several
hours before taking t em per at ure measurements. Prevent problems by
replacing dirty air filters and keeping the air path clear.

2. Slip fingers between the screen
frame
3. Using both hands…
The “screen” you are removing is 2 or 3 inches thick.
Pull out at the bottom first, to separate the latchhooks from the latches. It comes out with a “pop.”
The screen should now be loose at the bottom, but
still attached at the top.
Slip fingers between the screen frame and the
display chassis, as close to the top latches as
possible and pull the top of the screen from the
latches.
Carefully remove the screen and set it aside.

4. Assemble the lower row first.
5. Stack the next higher row.
6. Insert a supplied fastener.
Line up the legs for the bottom row as straight as
possible.
Insert a ¼” X 2 ½” bolt through the holes as shown
in Figure 1. Tighten a nut securely on this bolt.
Secure the legs to the floor. Use the tapped 5/16-18
holes in the front and rear of the legs. You can put an
eye-bolt in this hole and secure it to the floor with a
lag screw. Or use angle bracket, screwed to the floor
and bolted to this hole in front and rear. Or use the
optional
putting the lower row of displays on it.
Before going to the next higher rows, see that the
bottom row is straight. From one end of the line, look
along the front of the displays. The line should be
straight and flat. Level is not as important as straight
and flat.
Slide the legs of each display into the mating sockets
of the display in the first (lower) row. Check it for
“straight and flat.”
Insert a bolt through the hole in side wall of the lower

Installing a video wall with Ultra-Thin
Mullion Screens is a little more complex
than installing the wall with standard
mullion screens. Mechanical alignment is
more critical, and the larger the video
wall, the more precisely each unit must
be aligned to produce a good looking
image. The outcome of this alignment
process is partly dependent on how flat
the floor is, but it is most ly dependent on
how tightly the displays are fitted to each
other.

using the 5/64-inch Allen hex wrench, and set
them aside.
B. Grab the sides of the screen, or use the finger
holes, and lift it up about half an inch (1 cm), and
remove it from the adapter plate. Set it aside.
A. Assemble the lower row first. Line up the legs for
the bottom row as straight as possible. Insert a
¼” x 2½” bolt through the holes as shown in
Figure 1. Tighten a nut securely on this bolt, but
not so tight as to bend the legs. From one end of
the bottom row, look down the row. See that all
the units are aligned, that the line of the front of
the display units does not curve forward or
backward, up or down. The straighter the first
row, the better the finished wall will be. And the
easier it will be to get in right.
B. Secure the legs to the floor. Use the tapped 5/16-
18 holes in the front and rear of the legs. You can
put an eye-bolt in this hole and secure it to the
floor with a lag screw. Or use angle bracket,
screwed to the floor and bolted to this hole in front
and rear. Or use the optional
securing it to the floor and putting the lower row of
displays on it. Stack the next higher row. Sliding
the legs of each display into the mating sockets of
the display in the first (lower) row.
C. Insert a bolt (supplied). Insert a bolt through the
hole in side wall of the lower unit and into each
leg of the unit above. Tighten a nut on this bolt to
lock the units together. See Figure 1 above.
Tighten all the bolts after you have checked for
straightness, as in Step A above.
D. Continue with higher rows of displays. Lock each
display to the adjacent displays after the row
above it (if any) has been installed. Check for
straightness on each row.
E. For added stability, use the tapped holes in the
rear of the legs of the upper units to fasten to a
solid support, such as a structural wall. The
threaded inserts in each leg are female 5/16-18
UNC.

F. Check that all displays in the video wall are
locked together. And straight.
3. Start with the display unit in the
center of the bottom row. This
will be the Base Unit. Align the
Base Unit’s adapter plate.
(If the
bottom row has an even number of
display units, choose either middle
one. This step can be done before
the wall is built, if necessary.)
A. Look at the sides of the Adapter Frame. (See
Figure 3, below.) Starting at the top edge and
moving down you will see a large Locking Screw,
a pointed Alignment Bolt, and an Alignment Hole.
Near the middle of each side is a threaded hole
for the Alignment Tool’s spring-loaded screws.
(Do not attach the Alignment Tool yet.) At the
bottom of the side notice the Alignment Hole, the
Alignment Bolt, and the Locking Screw.
B. Look at all the Alignment Bolts of all units. They
should all be the same distance out. The factory
standard is 3/32
nd
of an inch, measured to the
base of the hex nut, or three full revolutions of the
bolt from when it is completely down against the
frame.
C. Check to see that the Adapter Frame of the Base
Unit is centered on the chassis. If the frame is not
centered on the chassis opening, for instance, if it
is offset to the left, then all the other frames will
have to be offset in this same direction. It is best if
this first frame is nicely centered on its chassis
opening.
D. Check to see that all the Locking Screws are
tight.
E. Measure the opening diagonally, from corner to
corner in both directions, and compare the
results. Be sure to measure from exactly the
same points each time. An accuracy of 1/32
inch (0.8 mm) is necessary for most applications,
but the more accurately you can do this,
particularly in the bottom center unit, the better
the video wall will be aligned and the better the
picture will look.
F. If the two measurements are the same, you have
a rectangle with perfectly square corners,
nd
4. Working along the bottom row
in both directions, align each of
the adapter plates, using the
Alignment Tool.
and you may go on to Step 4.
G. If the two measurements are not the same, within
nd
1/32
inch (0.8 mm), the frame is not a rectangle
with perfectly square corners, it is a
parallelogram.
Loosen the top Locking
Screws on each side. Move the adapter plate left
or right a bit and tighten the screws. Measure the
diagonals again. Repeat this process until you are
satisfied that the two diagonals are the same.
This means the adapter plate is a perfect
rectangle with square corners.
A. Now that the center unit adapter plate is squared,
align one of its neighbors in the bottom row.

5. Align the adapter plates on the
units above the Base Unit,
working upward.

B. The diagram above shows the order in which you
should align the displays in a typical video wall.
(Note: This is not the same as the Unit ID
address of the display units.)
C. The Alignment Tool fits over the seam of two
adjacent adapter plates. The Tool has six guide
pins, three on each side, and four spring-loaded
screws, two on each side. (Only two of the springloaded screws, one on each side, will be used at
a time.)
D. Position the Alignment Tool between the two
displays. One of these (#1) is already square and
the other (#2) is about to be aligned. Fit the tool
into display #1 first and attach it with the lower
spring-loaded screw. The guide pins should go
into the Alignment Holes in display #1.
E. Loosen the two Locking Screws in #2 on its right
side under the Alignment Tool and move the
adapter plate of display #2 until the guide pins go
in the Alignment Holes. Secure the Alignment
Tool to #2 with the spring-loaded screw. Tighten
the two Locking Screws on #2 under the
Alignment Tool. (Do not be concerned about the
units in the row above at this time.)
F. With the Alignment Tool still in place, check
display #2 for squareness by measuring the
diagonals. Loosen the Locking Screws on #2 that
are on the other side from the Alignment Tool,
and adjust adapter plate #2 until it is squarecornered rectangle.
G. When you are satisfied that display #2 is aligned
to display #1 and it has perfectly square corners,
remove the Alignment Tool. (If you have two
Alignment Tools, leave this first one in place, and
put the second on the other side.)
H. Go to the display on the other side of the center
display (#3) and align it to the center display,
following the steps 4.C through 4.G.
A. Start with the display above the Base Unit. Align
display #4 to display #1. Put the Alignment Tools
on either side of the Base Unit, #1. The upper
uide pin should now fit the bottom Alignment

6. Hang the screens on the
bottom row and adjust them in
or out so their front surfaces
are flat with each other.
Hole of #4. Loosen the bottom Locking Screw in
#4 and make it fit. Do the same on the other side,
moving the Alignment Tool, if you have only one.
B. Measure the diagonals of #4. Loosen the top two
Locking Screws and make its corners square,
then tighten the screws.
C. Continue with display #5, working your way up the
video wall to the top.
D. When you have completed the inverted-T, use
these as a frame and align the other units to it,
working from the lower rows upward. For each
display, you should be sure it is the correct
distance vertically and horizontally from all its
neighbors and that each unit’s diagonals are
equal.
A. Hang the screens on the bottom row. Be sure the
finger holes are on the top of each screen. When
each screen is seated, pull on it slightly to make
sure it is secure at both the top and bottom.
B. Notice the seams. Are the two screens flush at
each seam? If not, note how much you will have
to adjust one of the screens to make it flat and
flush with its neighbor. Measure this amount, but
be careful not to scratch the screens. Also, sight
along the row from the end. Look down the groove
on the top of the screens. This helps to prevent
where the corners match,
but the screens are not flat. Make a diagram of
the video wall and note how far to move each
corner of each unit in or out. Try to get the wall flat
within 1/32” inch (0.8 mm)
C. Remove the screens again.
D. Working from your notes, adjust the pointed
Alignment Bolts with the ½-inch wrench. Looking
at the display from the front, each complete turn
of the bolt CW (clockwise) pulls the corner of the
screen IN (away from you) by 1/32nd of an inch
(0.8 mm).
E. Hang the screens again and check your work.
F. With the screens in place on the bottom row, put
the screens on the next row above. “Flatten” this
row in the same way, paying attention to how
these fit with the bottom row as well as with their
neighbors to the left and right.

7. Put retaining screws in the top
row and cover holes and seams
with black tape to prevent light
leaks.
A. When all the screens are aligned with each other
to make a flat, square video wall, put the screws
in the top row of screens to hold them in place.
B. The finger holes and the space between the
screen and the adapter plate can be a source of
light leaks, allowing stray light to hit the back of
the screen and wash out some of the picture. To
prevent this, cover the finger holes in the top row
of displays with black cloth tape. “Gaffer” tape
does a nice job of this. Masking tape is
sometimes difficult to remove cleanly. You can
check for light leaks during the video setup
process. Select “Curtain” from the main menu and
verify that the whole screen is black. It is best to
do this in the actual lighting that will be on when
the wall is used.

Cables
Video connections from the signal source t o the WN-5220-S depend
on the type of signal supplied by the source. The com pat ible video
inputs are; PC 800x600 (SVGA), PC 640x480 (VGA), MAC 800X600
or 640X480, and 31.5 kHz (progr essive scan) RG BS Video. The VIM300 option recognizes 15.75 kHz (interlaced) RGBS video, composit e
video, and S-Video for NTSC, PAL and SECAM. These will be
processed and displayed.
The Loop-thru video output uses a standard 15-pin VGA t ype
connector for output to an external com puter monitor or another
display. The format of t he Loop- t hru video is same as the source
video. VGA and MAC will have RGB with separate H-Sync and
V-Sync. RGBS video will come out RGBS with the composite sync on
the connector’s H-Sync pin. RGB Sync on Green sources will loopthru RGBS-Sync on Green. Displays with the VIM-300 option also
have a Composite Video and S-Video loop-thru connectors.
The video cables used should be high quality and shielded to insure
the best image quality when displayed.
Using poor quality cables can lead to picture noi se, jitter and
crosstalk.
Control data enters the display via the RS-232 In connection, and is
supplied to an adjacent display (if used) via the RS-232 Out
connector. High quality shielded cables designed for RS-232
communication should be used to ensure proper data transm ission
and control.
