1. INTRODUCTION
This UHD+ 1 by 4 HDMI Video Wall Processor can take any standard
4K (or lower) HDMI source and generate a high quality 2×2 video
wall with bezel compensation and full audio bypass. The HDMI input
supports 4K UHD+ HDMI video, up to and including 4K@60Hz (4:4:4,
8-bit) as well as 10/12-bit sources with HDR. Each of the unit’s 4
outputs generates 1080p@60Hz video which allows for the creation
of a full resolution 4K video wall from 4K sources. Built in advanced
EDID management options including Internal, External, and User
congurations, as well as advanced HDCP management, allows
this video wall processor to handle almost any source situation.
Additionally, multiple video wall processors can be used together to
generate video walls with congurations as large as 8×8. A dedicated
PC application allows the user to fully customize the video wall and
associated features. Additional control interfaces are also available
including RS-232, and Telnet.

6.4 Video Wall App
The PC based Video Wall App provides complete control over one
or more Video Wall Processors via Ethernet or RS-232. This software
can scan the local network, as well as any RS-232 connections on the
PC, for controllable units to add to the current video wall grouping.
Commonly used video wall congurations can be quickly selected or
the conguration can be manually set up.
In addition to video wall setup this software can also be used to
congure the network, EDID and HDCP settings, if needed.
6.4.1 Software Operation
Please obtain the “Video Wall App” software from your authorized
dealer and save it in a directory where you can easily nd it.
Ensure that all the units you wish to control have been powered on
and that they are all connected to the same network as your laptop/
PC. Start the software by double clicking on the *.exe le to start the
Video Wall App software.
By default, when the software starts, the layout will be empty and
no units will be connected. To add one or more physical units (with 4
displays per unit) to the video wall layout, click on the “Connection”
button to open the “Connection Window”.
Note: This software is only compatible with Windows 7 or later PCs.
6
6.4.2 Connection Window
By clicking on the “Connection” button at the top-left corner of the
main window the “Connection Window” will open up and list all Video
Wall Processors that are currently detected on the local network as
well as listing all available RS-232 ports on the PC. Each detected unit
can then be added to the current video wall layout and assigned a
unique ID number.
Once all units have been added to the list, click the “Connect” button
to connect to all of the units. If desired, the order of the units, if more
than one is required for the video wall, may also be changed here.
Once everything is congured, click “OK” to close the window and
return to the Layout tab.
Note: Units connected via RS-232 can’t be directly detected, so all
available serial ports will be listed, even if they do not currently have a
connected unit.
1) All Units List: All detected units on the local network as well as all
available local serial ports are listed here. All detected units are
identied by their IP address. Selecting a Unit (or serial port) and
then clicking the right arrow button ( ) will place them in the
Selected Units window in the order they are added. The Ethernet
details of each detected unit may also be changed by clicking on
the associated details icon ( ).
Note: A unit’s Ethernet settings cannot be changed if the software
is actively “Connected” to it. To make changes, please press the
“Disconnect” button rst.
7
■ Refresh Button: Click this button to detect any additional units
that were added to the network after the window was opened.
2) Selected Units List: All selected units will appear here with an ID
number indicating their order to be added to the layout. To re-
move an individual unit from the list, click the “x” in the unit’s “Del”
column.

numbers next to each unit and click on this button.
Note: ID numbers can only be changed while a unit is discon-
nected.
■ Clear Button: Click this button to remove all units from the Se-
lected Units list.
8
3) Connect Button: Clicking this button will activate the software's
connection to all units in the Selected Units list, allowing control

green circle next to each successfully connected unit.
4) Disconnect Button: Click this button to disconnect the software
from all units. The “Stat” column will show a gray circle next to disconnected units.
6.4.3 Layout Tab
The Layout Tab provides control over the dimensions of the video wall
as well as how much bezel compensation to apply. The video wall’s
general appearance, and the position of the 4 displays connected
to each unit, is represented by the large window to the right. Each
display is labeled with the unit’s ID# and output letter. The number of
currently connected units is displayed at the top of the tab.
9
1) Video Wall Geometry: This section sets the number of displays used
in the video wall. Up to a maximum of 64 displays can be supported (8×8 video wall).

wall dimensions. Options are: 1×1, 1×2, 1×3, 1×4, 2×2, 3×3
10
2) Bezel Settings: Congures the bezel size to compensate for around
all displays.
Note: Bezel settings assume that the top/bottom and left/right be-
zel pairs are uniform in size and all displays in the video wall share
the same dimensions.
■ Bezel Enable: Click this button to enable or disable the use of
bezel compensation.
■ Horizontal: Set the size, in pixels, of the vertical bezel
compensation. (Maximum value is 50)
■ Vertical: Set the size, in pixels, of the vertical bezel
compensation. (Maximum value is 50)
3) Set Button: After fully dening all components of the video wall,
or after making changes to an existing layout, click this button
to conrm the new settings and transmit them to the connected
units.
6.4.4 Settings Tab
The basic conguration and settings for each connected unit can be
set here by selecting the unit to congure from the “ID-NAME” list on
the left side. To exit the setting conguration tabs and return to the
layout mode, click on the “Layout” button in the upper-right section
of the window.
11
1) System Menu: This window provides information about the select-
ed unit’s serial number, and rmware version as well as providing a

click “Save”. To upload a custom User EDID, insert a USB thumb
drive, with a valid EDID le named “USEREDID.BIN” in the root
directory, into the unit’s USB service port then click the “Upload”
button.
Note: After the rmware upload is complete the unit will
automatically reboot.
13
■ Sync Indicator: When a live source is detected, this will be
green, when no source is detected it will be grey.
■ EDID Selection: Select the preferred EDID for the unit to use
from the dropdown menu. This unit provides the option of six
standard EDIDs, four sink sourced EDIDs and one user uploaded
EDID.
Note: In most cases, assigning a new EDID to an input will cause
the affected input to briey blink out while the source adapts
to the new information.
This unit provides the following 6 default EDIDs:
Unit’s Default EDIDs
FHD/2CH 1920×1080p@60Hz (4.95Gbps) & 8-bit color,
