V-Match C9 - Installation and Operation Manual 9

INSTALLATION
Before setting up and calibrating a V-Match C9 video wall, please make sure the necessary
hardware and software components have been installed. The following tasks have to be
completed:
• Assemble video wall
• Connect digital displays to V-Match C9 via DVI-DVI or DVI-HDMI cables. Make
sure you know which displays are connected to the V-Match C9 output ports, i.e.
which displays are “Display 1”, “Display 2”, etc.
• Connect video sources
Input connections via breakout cables and adapter
• Install V-Match C9 Control program (on enclosed CD) on control PC (see chapter
“SETUP” below)
• Connect control PC to RJ-45 port on the rear panel of V-Match C9 using a serial cable
(scope of supply: green patch-cable + serial-to-RJ45 adapter + in some cases the
serial-to-USB adapter cable plus Drivers on little CD) 1
• Switch on power of all displays, then of V-Match C9, then of your control PC, and
finally of the video sources.
1 Make sure to choose the right COM port dedicated to the port on the PC your serial cable is connected to. The
software V-Match C9 Control allows changing the COM port: Select “File -> Preferences…” in the menu bar on
top of V-Match C9 Control and set the right COM port. If the wrong COM port is selected, you cannot connect
to the V-Match C9 hardware and an error message says: “Installation error opening port”.
V-Match C9 - Installation and Operation Manual 10

SETUP
To set up a video wall the V-Match C9 Control software is used. The software is installed on
a control PC running Microsoft Windows XP, Vista, 7 (PC not delivered). To setup
communication between software and hardware, a serial connection between PC and V-Match
C9 hardware is required. Plug the green patch-cable with RJ-45 connectors (delivered) into
the RS-232 port (down pointing arrow) on the rear panel of V-Match C9. Use the silver RJ-
45-to-serial adapter (delivered) to connect the green cable to the serial port of your PC. If
there is no serial port on your PC use the USB-to-serial (RS 232) adapter cable (delivered) to
connect to a USB port of your control PC.
Serial connection
Install the V-Match C9 Control program on your control PC by entering the CD (delivered)
and double-click VMatchC9Control.msi file. By default, this program will be installed at
C:\Programs\HETEC\V-Match C9 Control\ with a shortcut menu icon on the desktop of your
control PC. Double-click the menu icon “V-Match C9 Control” on your desktop to start the
program.
V-Match C9 - Installation and Operation Manual 11

V-Match C9 Control
Presets
Four Presets can be set up using V-Match C9 Control. Each Preset can be saved on the V-
Match C9 hardware. It then can be activated using the V-Match C9 Control program on a
control PC or pressing the front panel buttons on the hardware. Presets are video effects such
as video enlarged across multiple displays, full screen images, Picture-in-Picture (fixed to
bottom right corner of the video wall), Picture-aside-Picture (free positioning and scaling of 2
video sources on the video wall), and zoomed visualisation of the video sources connected.
Start setting up “Preset 1” following the steps described below. When set up, this Preset 1
shows the video source(s) enlarged across all displays at maximum zoom-out factor on the
video wall. The video will be shown as big as possible and at minimum cut off of content. 2
2 If the aspect ratio of the total video wall is different to the aspect ratio of the video input source(s) content
needs to be cut off either on the right, left, top, or bottom in order to have an undistorted image on the video
wall. For example a very wide panorama video wall made of 1x9 screens each with a 16:9 aspect ratio results in
a total video wall aspect ratio of about 144x9. The input source may have a Full HD 1920x1080 resolution with
16:9 aspect ratio: V-Match C9 allows you to cut out a very wide panorama stripe with a 144x9 aspect ratio. The
rest content on top or below this stripe will be cut off. The image on the panorama video wall appears natural
and 100% distortion-free. If the rest content would not be cut off, it would be pressed (from the top and from the
bottom) into the panorama video wall, resulting in a distorted, un-natural viewing experience.
V-Match C9 - Installation and Operation Manual 12

Preset 1: a video enlarged across all displays
Once having setup Preset 1, you can generate Presets 2, 3, and 4 simply by copying all
settings of Preset 1 and then change video sources, zoom factors etc. to generate different
video effects for different Presets (see chapters “Copy & paste Presets” and “Generate video
effects”). First, start with Preset 1 (selected by default).
Define input signals
The first step in setting up a V-Match C9 video wall is defining the input signal. Up to 2 input
signals can be shown simultaneously on the video wall.
Define “Input Main”
The video source defined as “Input Main” in a Preset will always overlap the video source
defined as “Input Sub”, unless both sources are put side by side without overlapping.
Click on the menu tab “Input Main” on the left side of V-Match C9 Control. As “Input
Signal” select one of the sources connected: DVI/HDMI, VGA/YPbPr, S-Video, CVBS.
Now select the “Aspect Ratio of Input Signal”. The native output resolution of the source
defines the aspect ratio. Move your mouse cursor above the aspect ratio box and wait for the
dialog listing examples of resolutions with that aspect ratio or see the Appendix with a list of
common resolutions and aspect ratios.
V-Match C9 - Installation and Operation Manual 13

Green background in wide-screen format at an input signal resolution of 1920x1080 (16:9 aspect ratio)
The green background on the right side of V-Match C9 Control stands for the full image of
the source connected. Depending on the aspect ratio / resolution chosen, the green background
is shown in wide-screen or standard aspect ratios.
Instead of the green background you can select a background image (i.e. a screen shot of the
video content to be displayed on the video wall): Select “File -> Preferences -> Input ->
Browse” in the menu on top of V-Match C9 Control.
Define “Input Sub”
If a second video input source is connected to V-Match C9 and if it also has to be shown on
the video wall in this Preset (Preset 1) it is setup under the menu tab “Input Sub” in the same
way as “Input Main”. A blue rectangular appears on the bottom right corner of V-Match C9
Control and shows size and position of “Input Sub”.
V-Match C9 - Installation and Operation Manual 14

Blue background in 4:3 aspect ratio at an input signal resolution of 1600x1200
Note: Input Main and Input Sub can be set to the same source to show a single source as PiP
or PaP two times on the video wall.
Select “regular” or “free” video wall
The second step in setting up a video wall is defining the video wall as “regular” or “free”.
A “regular” video wall is a matrix made of the same type and model of display. In addition,
all horizontal gaps between all displays are exactly the same. The same applies to all vertical
gaps between displays.
In a “free” video wall, different displays with different screen sizes, resolutions, and aspect
ratios can be combined to create an exclusive video wall design. The position of each display
as well as gaps between displays can freely be chosen. To set up a “free” video wall, please
read on at chapter “Set up FREE video wall” further below.
Set up REGULAR video wall
Regular-STEP 1: Select “regular”
To setup a regular video wall, select “regular” in the menu tab “Wall” on the left side of V-
Match C9 Control.
V-Match C9 - Installation and Operation Manual 15

Regular-STEP 2: Define video wall matrix
Then choose the number of horizontal and vertical displays in the boxes under “Displays in
Wall”. Each display is shown as white rectangle on top of the green background (or individual
background image) on the right side of V-Match C9 Control. You can choose a 1x2, 2x1, 1x3,
3x1, 4x1, 2x2, 2x3, 3x2, 4x2, and 3x3. For other matrix setups like 1x9, 7x1, 1x4, 2x4 you
need to define smaller “Dimensions of selected Area” in order to fit this matrix into the
control software: instead of 400 for “horizontal” enter e.g. 150. All white rectangles now
appear smaller in the software and each display will show a smaller portion of the total input
source. Now you can enter the display matrix required e.g. 9 “horizontal” and 1 “vertical” to
create a very wide panorama video wall.
Regular-STEP 3: Set native output resolution
Now select the native resolution of the displays used in the video wall. The drop down menu
under “Video Mode (of all Displays)“ lists all standard VESA resolutions supported by V-
Match C9. Select the native resolution of the type of display used in the video wall.
Note: Regular video wall = all displays are the same type and model and thus the same
resolution.
V-Match C9 - Installation and Operation Manual 16

Select native resolution of all displays
Regular-STEP 4: Connect
Now start the communication between the V-Match C9 Control software and the V-Match C9
hardware. Press the red-green-double-arrow icon or “Communication -> Connect to device”
in the menu bar on top of V-Match C9 Control.
Initializing communication takes some seconds. As soon as the connection is set up, V-Match
C9 Control shows “connected” and a green dot on the bottom right in the program. If the PC
cannot connect to the V-Match C9 hardware an error message says: “Installation error
opening port”. Make sure to choose the right COM port. 3
3 See footnote 1 on how to select the right COM port.
V-Match C9 - Installation and Operation Manual 17

Regular-STEP 5: Apply
Now press “Apply” to send all settings from the program/PC to the V-Match C9 hardware.
Note: Wait until the setup is built up and LED 1 shows constant green light. This may take
up to 1 minute!
Settings will be activated and visible on the video wall. This takes several seconds (as it is the
first time you press “Apply” and the video boards are configuring for the first time). Settings
are built up display by display. The status LED 1 on the front panel of V-Match C9 is
blinking green. Wait until the setup is built up and LED 1 shows constant green light.
On the video wall an area of the input video defined as “Input Main” is shown enlarged across
all displays. But there are jumps in the image causing an unnatural viewing experience. These
jumps come from gaps between displays V-Match C9 can compensate for by fine-tuning. 4
4 V-Match C9 is able to compensate for gaps by removing the areas of the input image covered by the gaps,
preventing unnatural jumps from one display to the next. Please note that compensating for gaps will hide some
parts of the input image. If you need to show the input image’s entire contents, leave vertical and horizontal
“Gap between Displays” at 0. Just finish fine-tuning by increasing the value of horizontal or vertical
“Dimensions of selected Area” as much as possible.
V-Match C9 - Installation and Operation Manual 18

Regular-STEP 6: Fine-tune REGULAR wall preset
The last step is fine-tuning Preset 1. To fine-tune “regular” video wall Presets adjust the
horizontal and the vertical “Gap between Displays” under menu tab “Wall”. The frames
around screens and gaps between displays mounted in the video wall are parts where there is
no screen and thus no video. These gaps can be set in the V-Match C9 Control program to
remove all jumps in the image on the total video wall: Larger frames around screens and
larger distances between displays will result in larger distances of the white display rectangles
(and larger values for gaps) in the V-Match C9 Control software. A white rectangle only
shows the visible section of a display: the screen. Adjust the horizontal and the vertical “Gap
between Displays” as follows:
First, make your video input source (defined as “Input Main”) show a test image with lots of
lines spread across it: diagonal, vertical and horizontal lines (if a PC is connected as video
input source the program “Microsoft Paint” can be used to create a test image).
Test image with horizontal, vertical, and diagonal lines
In a perfectly mounted “regular” display wall all horizontal and vertical lines align perfectly
across all displays in the video wall. 5 Just diagonal lines will not align and will have jumps on
the display wall.
5 If horizontal or vertical lines show jumps, your video wall is not mounted in a 100% regular way. V-Match C9
allows fine-tuning this video wall as well: Click on “Wall” and select “free” instead of “regular”. Now follow the
steps described in chapter “Fine-tune FREE presets”
V-Match C9 - Installation and Operation Manual 19

To align diagonal lines, first set the “horizontal” gap for displays positioned in rows. Increase
the value for “horizontal” (start increasing the value carefully with about 10 units per step) in
the menu tab “Wall” and press “Apply”. This takes some seconds. The status LED above
front panel button 1 on the hardware is blinking green during applying. Then the changes are
visible on the video wall: The jump between all displays in a row has decreased. Repeat until
the diagonal lines align perfectly from one display to the next in the rows on the video wall.
Now set the “vertical” gap for displays positioned in columns. Increase the value for
“vertical” and press “Apply”. Repeat until the diagonal lines align perfectly from one display
to the next in the columns on the video wall.
Finally, increase the value of horizontal or vertical “Dimensions of selected Area” as much as
possible.
You have now calibrated the video wall and created Preset 1: The video input source(s) is
shown enlarged across all displays at maximum zoom-out factor on the video wall. The video
will be shown as big as possible and at minimum cut off of content. 6 Gaps are compensated
for resulting in a natural, distortion-free image on the video wall.
You can copy the settings of Preset 1 to quickly generate other Presets and video effects as
described in chapters “Copy & paste Presets” and “Generate video effects” further below.
Select all displays (Ctrl + A) and reposition and resize them freely on the input image via drag
and drop.
Regularly save settings to your control PC as described in chapter “Save and download
Presets”.
Setup FREE video wall
Free-STEP 1: Select “free”
To setup a free video wall, select “free” in the menu tab “Wall” on the left side menu of V-
Match C9 Control after having defined “Input Main” and “Input Sub” described above.
6 See Footnote 2 on why content is cut off whenever aspect ratios of input signal and video wall differ.
V-Match C9 - Installation and Operation Manual 20

Free-STEP 2: Define number of displays
Then, define the “Number of Displays” mounted in the video wall (1-9 displays).
Free-STEP 3: Set native output resolutions
Now set the correct native output resolution for every single display: Go to menu tab “Display
1” on the left side of V-Match C9 Control or click into the white rectangle “Display 1” on the
right side of the control program. Open the drop down menu “Video Mode” and choose the
native resolution of the display connected to output port 1 of V-Match C9. Make sure you
select the native resolution of the particular display connected (check technical specifications
of that display).
V-Match C9 - Installation and Operation Manual 21

Select native resolution of each display
Repeat for the next output resolution until the output resolutions for all displays have been
configured.
Free-STEP 4: Set screen sizes
In the following steps, you will create a configuration that will display the video source
defined as “Input Main” enlarged across the entire video wall 7 .
7 This configuration will be automatically stored as Preset 1. Preset 1 is active by default, so you do not need to
change any settings to select Preset 1.
V-Match C9 - Installation and Operation Manual 22

Preset 1: a video enlarged across all displays – setup in V-Match C9 Control and live on the video wall
To set up the screen sizes, you will need to convert the sizes of the screens in your physical
video wall to unit sizes in the V-Match C9 Control program. Units in the control software
range from 0 to 1920 for “x” (horizontal range) and from 0 to 1200 for “y” (vertical range).
This equals the maximum output of 1920x1200 of V-Match C9.
To calculate the size of a display in units, use a unit conversion factor that lets you convert
the display sizes to the units used in the V-Match C9 Control program. Use the total width of
your video wall to look up this unit conversion factor in the table below 8 .
8 If the height of your video wall is greater than the width, look up the conversion factor using the height instead
of the width. Even when using the total height to decide the conversion factor, calculate the size of the displays
based on the displays’ width.
V-Match C9 - Installation and Operation Manual 23

video wall width conversion factor
(units per cm)
less than 2m 9
2m – 4m 4
4m – 6m 3
6m – 8m 2
8m – 10m 1
Next, measure the width of the visible area of each display. Convert it by multiplying the
width in centimeters by the conversion factor to get the width in units (see Example below).
Attention: Please take care to measure the visible area of the displays as exactly as possible.
Do not include the frame around the screen in your measurement.
Note: The visible width of the display is measured without the frame
Example:
Display visible width: 36.7 cm
Video wall width: 2.70 m
Conversion factor 4 (units per cm)
Display width in units: 36.7 x 4 = 146.8,
rounded to 147
Enter the individually calculated value for each display in the V-Match C9 Control program
in “horizontal” under “Dimensions of selected Area” (the “vertical” dimension value
automatically gets changed in the control program).
V-Match C9 - Installation and Operation Manual 24

Enter calculated screen size in “horizontal” in “Dimensions of selected Area”
Repeat for all displays. All screens then are calibrated regarding their size: Different sized
screens in the physical video wall are shown as different sized rectangles in V-Match C9
Control.
Free-STEP 5: Position displays approximately
In V-Match C9 Control, use drag and drop to position the displays/rectangles in the shape of
your video wall. For now, it is enough to create a rough approximation, as you will fine-tune
the exact positions of the screens in the next step. Regularly save settings to your control PC
as described in chapter “Save and download Presets” further below.
V-Match C9 - Installation and Operation Manual 25

Free-STEP 6: Connect
Now start the communication between the V-Match C9 Control software and the V-Match C9
hardware. Press the red-green-double-arrow icon or “Communication -> Connect to device”
in the menu bar on top of V-Match C9 control.
Initializing communication takes some seconds. As soon as the connection is set up, V-Match
C9 Control shows “connected” and a green dot on the bottom right in the program. If the PC
cannot connect to the V-Match C9 hardware an error message says: “Installation error
opening port”. Make sure to choose the right COM port. 9
Free-STEP 7: Apply
Now press “Apply” to send all settings from the software/PC to the V-Match C9 hardware.
Note: Wait until the setup is built up and LED 1 shows constant green light. This may take
up to 1 minute!
Settings will be activated and visible on the video wall. This takes several seconds (as it is the
first time you press “Apply” and the video boards are configuring for the first time). Settings
are built up display by display. The status LED 1 on the front panel of V-Match C9 is
blinking green. Wait until the setup is built up and LED 1 shows constant green light.
On the video wall an area of the input video defined as “Input Main” is shown enlarged across
all displays. It is an approximation only! There are jumps in the total image on the video wall.
Remove jumps by fine-tuning the position of all displays.
Free-STEP 8: Fine-tune FREE wall preset (positions)
To fine-tune, connect a test PC to the V-Match C9 system as an input source on “Input Main”,
and create test images to display on the video wall:
1. Switch to Preset 4 with the V-Match C9 Control program and select “free” in the
menu tab “Wall”. A non-configured Preset with a 3x3 matrix of white rectangles is
shown in the control program.
2. Now choose e.g. “Display 1” to use in full screen to create the test images on the test
PC.
3. Click “Display 1”, select the native resolution of that display from the drop down
menu, and enter “1920” in “horizontal” under “Dimensions of selected Area” (the
value “1920” might automatically change: this is fine!). Click “Apply”. It takes some
seconds until the settings are applied and the blinking of status LED 4 on the front
panel of the hardware turns into constant green light. Now the rectangle as well as the
display in the video wall show the PC’s entire desktop.

4. On the test PC, open a graphics editor (e.g. Microsoft Paint)
5. Create the two test images as described below
6. Switch back to Preset 1 for fine-tuning
Two types of test image are required for fine-tuning. One test image should have horizontal
and vertical lines, the other diagonal lines. Straight horizontal and vertical lines help you finetune
the alignment of displays. Diagonal lines that cross display boundaries help you fine-tune
the distance between displays. Draw lines in different colors and font sizes.
In the first test image, ensure that at least two horizontal and vertical lines are visible on each
display.

The test image as it should appear on the video wall after fine tuning
Having created the test images you can start fine-tuning the position of each display. Choose
one of the displays in the center of your video wall as a starting point. Do not change the
setting of this display but use it as a reference to fine-tune the location of the other displays
one by one.
All displays surrounding the center display are fine-tuned by adjusting “horizontal” and
“vertical” positions. Select a display and change the values for “horizontal” and “vertical”
positions. You can change values by
1. typing numbers into the boxes “vertical” and “horizontal” under “Position of
selected Area” in the display dialog on the left side of V-Match C9 Control,
2. clicking the up or down buttons beside these boxes (1 click = 1 unit),
3. using the arrow-keys of your keyboard of your control PC (1 hit = 10 units): left and
right arrows change vertical position, up and down arrows change horizontal position.
Start with small value changes of about 10 units. This will already show visible results.
After every change click “Apply”.
Note: To verify if the lines in the test images are aligned correctly between two displays, use
a straight object such as a long ruler. Also try to position yourself on a point of focus that
is in a 90° ankle to the section of the video wall you are fine-tuning. When aligning using
your straight object don’t focus from the left or right or from below or above the video wall
section: stand right in front of the section/display of the video wall you are fine-tuning.
Only a 90° ankle provides a distortion-free focus position.

Having fine-tuned the position of every display, you can disconnect the test PC with the test
images. Connect your video input source.
Now you can select all displays (Ctrl+A) and resize and reposition them (by drag and drop) as
a group to create the best image on the video wall. You have created the first Preset in your
video wall setup.
You can copy the settings of Preset 1 to quickly generate other Presets and video effects as
described below.
Regularly save settings to your control PC as described in chapter “Save and download
Presets”.
Copy & paste Presets
You can copy the settings of Preset 1 to quickly generate Presets 2, 3, and 4. Click “Edit” ->
“Copy Preset 1 to…” in the menu bar on top of V-Match C9 Control and copy the settings to
V-Match C9 - Installation and Operation Manual 31

all other Presets. Press “Apply”. This takes some seconds. All Presets now are calibrated and
have the same settings.
You can copy the settings of any Preset to any Preset.
Generate video effects
Choose a calibrated 10 Preset and just exchange video sources (as described in chapters
“Define Input Main” and “Define Input Sub”), zoom factors, PiP and PaP positions, etc. to
generate different video effects for different Presets. A single display or clusters of displays
can show different zoom factors. Select displays in a cluster (hold “Ctrl” while you select the
displays of a cluster) and resize and reposition them via drag and drop. Selected displays are
shown as red rectangles instead of white rectangles. To resize selected displays move the
mouse cursor on the very bottom right edge of the selected displays until the cursor-cross
turns into a double-arrow. To resize, now click, drag, and drop.
Click into the background images (green or blue rectangle or your individual screenshot).
When selected the background images have red frames. Now resize the images to zoom in or
out and reposition them as PiP or PaP. Input Main will always be on top of Input sub but you
can exchange the sources to put one on top of each other. Input Main and Input Sub can be set
to the same input signal to show a single source as PiP or PaP two times on the video wall.
