2 Wide x 2 Deep Video Wall Display (Rear View)
This display kit mounts the NEC X463UN
LCD monitor in a 2 wide by 2 deep landscape
configuration. The frame attaches to a wall and
receives the LCD monitors by way of four machined
fittings (per monitor) that thread into the monitor’s
VESA holes. These fittings then insert into the frame’s
channels. The monitor’s fittings secure to the frame
with locking arms that provide an easy way to remove
the monitors for service. A removable panel provides
access for media players behind the frame.
Important: Installing video displays is a serious
endeavor that requires experienced professionals.
Improperly prepared walls and other structures as
well as the equipment being installed can result in
property damage, injury and/or liability to the
installing contractor. Do not proceed if any part of
the installation is in doubt.
Caution: Due to the wide variety of structures,
environments, materials and installation methods, the
installing contractor must exercise good judgment in
selecting the proper mounting area. The mounting
structure must be capable of supporting at least 5
times the load of the installed equipment. Consult local
building codes for further guidance.
Follow these instructions for the most efficient and
safest mounting results.

Step 1: Mount Frame to Wall
Scribe a horizontal line on the
wall showing the exact location
of the top edge of the upper left
LCD monitor will be. Measure
down 8.8” (223.5mm) from that
line and scribe another
horizontal line showing where
the first location of the
adjustable lag bolts for the
mounting frame will be. This is
for the top left keyhole slot
(Figure 1).
Scribe a vertical line showing
where the left side of the upper
LCD monitor will be. Measure to
the right and scribe another
vertical line 12.6” (320mm) to
locate the location of the first
adjustable lag bolts for the
mounting frame will be. This is for the top right keyhole slot
(Figure 1).
Mark where the 2nd horizontal line vertical lines meets.
Measure 55.7” (1414.8mm) to the right for next location of the
adjustable lag bolt. Use a level then mark the second location,
use level to make sure it Is horizontally level to the first hole
on the left side. Pre-drill the marked locations using a 3/16”
(5mm) drill (Figure 1).
Install the adjustable lag bolts to the pre-drilled holes then
hang the frame onto the two adjustable studs. Install the flat
washer and hex nut to secure frame to wall. Hand tighten hex
nut only (Figure 2).
Step 3:
Mark the location for the other adjustable lag
bolts, one upper center keyhole, three bottom
keyholes slots and three center middle holes
(Figure 3).
Step 4:
Remove the two nuts and washer securing the
frame to the wall and place the frame back on
the floor. Pre-drill all the marked locations
using 3/16” drill bit then install the adjustable
lag bolts (Figure 3 and 4).
Step 5:

Re-place the frame on the wall then secure using the provided hex
nut and flat washer. Hand tighten hex nut only (Figure 4).
Step 6:
Using a 4 or 5 feet long level plum the frame by adjusting the
adjustable lag bolts on the vertical channels counter clockwise to pull
the frame frontward. Use the provided adjustment wrench to rotate
the adjustable lag bolts. Use the level or straight edge to make the
H-slat horizontally straight by adjusting the adjustable lag bolt closest
to the H-slat (Figure 5).
Step 7:
Once the frame is plummed and level tighten the hex nuts
permanently.
Step 8: Install Brackets to Media Player
Attach the media player brackets to the sides of the media
player using its existing side screws (Figure 6).
Step 9: Install Media Player
Choose and remove the bottom left or right lower H-slat frame by
unscrewing its flat head screws (Figure 7). Install the media player to
the wall between the two vertical channels using the appropriate fasteners
through the media player’s brackets (Figure 7). Re-install the bottom
lower H-slat.

Step 10: M6 threaded stand-off buttons to LCD monitors
Thread four M6 threaded standoff-buttons into the outer VESA mounting holes at the
back of each monitor (Figure 8).
Step 11: Install Monitors to the Left Column
Starting with the upper left monitor, connect power and signal wires to each monitor.
Lift up locking arms on the left side of the frame. Align the four stand-off buttons with
the four large slots in the H-slats then slide the monitor from left to right until it stops
then pull down the locking arm to lock into place (Figure 9). Repeat step 11 for the
lower monitors.
Step 12:
Note on
alignment:
While installing
monitors, check
for front and side
alignment of the
monitors. The
surfaces of all monitors must be aligned and flush to each other. If
one or more screens are tilted more than others use the adjustment
bracket to reach the hex portion of the M6 threaded buttons at the
rear of the monitor and rotate counter clockwise to pull the front of
the monitor forward or rotate clockwise to push it back ward. If
access to the rear is not accessible remove the screen(s) and,
depending whether the monitor needs to be tilted forward or
backward rotate the buttons using the adjustment wrench or a flat
head screw driver (Figure 10). Reinstall and recheck surface
alignments. Repeat where necessary.
Step 13:
Install Right Column Monitors
Starting with the upper right monitor, connect power and
signal wires to each monitor. Lift up the locking arms on the right
side of the frame. Align the four stand-off buttons with the four large
slots in the H-slats then slide the monitor from right to left until it
stops then pull down the locking arm to lock into place
(Figure 11). Repeat step 12 for the lower monitors. Check for front
and side alignments. Refer to Step 12 for front alignment process.
