Creating Custom Video Walls

Collecting coordinates from a digital drawing

▪ First convert your design drawings into 1920x1080 resolution with a 16:9 aspect ratio and pick up the coordinates

at the Top Left and Top Right corners in each active LCD display region, then input these in to the scaler via the
OSD or PC tool (GAlign). The original point for the coordinate system is set at the Top Left corner as (0, 0).

▪ Please note that the coordinate system (16:9) in the H&V directions should have the same scaling ratio.
In above drawing, the coordinates for TV1 and TV2 are as follows:

▪ TV1 coordinate for Top Left corner=(0, 586)，Top Right corner=(366, 216)
▪ TV2 coordinate for Top Left corner=(815, 635)，Top Right corner=(447, 286)

▪ Please pay attention to the display direction of the TV

Collect coordinates from photo

▪ You can also take a picture of the LCD array and resize this photo into a 1920x1080 resolution to locate the 8

points of the 4x LCDs, then input these into the scaler using the following process

▪ Trim the edge of the display area so that the edge of the LCD screen (not including bezel) is touching the edge of

your image.

▪ Resize to 1920x1080 image resolution in JPG or PNG format.
▪ You can view this photo in Microsoft “Paint” and can use the mouse to capture the coordinates by using the select

6. Use the GAlign PC tool or the OSD to input coordinates for each scaler

7. Fine tune if necessary.

Uploading coordinates via the remote control

▪ After collecting the coordinates for all LCD’s, you can upload the coordinates into the scaler though the OSD.
▪ Example: Storing custom mode in Mode 2:
▪ [Video wall]→[Manual Mode]→[Mode 2]
▪ Select [TV1]→ Select [Top Left/Top Right]→ Slide bar to input Coordinates→ TV1 Done.
▪ Back to select [TV2]→ Select [Top Left/Top Right]→ Slide bar to input Coordinates→ TV2 Done.
▪ The next step is to execute the same procedures for TV3 & TV4.
▪ You may have some difficulty seeing the OSD to set Coordinates. The GAlign tool can simplify this process

Upload coordinates into the scaler via the [GAlign] PC tool

▪ Please see the GAlign PC Tool section for details on this procedure

Create custom modes with multiple units cascaded

▪ First take a picture or make drawing similar to [Figure A] as shown above. Assign 4 LCDs to one scaler and then

4 LCDs to the next scaler and repeat as necessary. Follow the same procedures as described in previous section.
You will need to do further [Video Wall] settings using [Zoom], [Pan] and [Overlap]. You can find further
information about these settings above.

User Manual English

Below is a picture to show a video wall designed with 4x scalers together with 15x 55” LCDs. You can take pictures

after the LCD installation, then to collect two coordinates for each LCD and input the data in to each scaler by using
the GAlign PC tool. You may need to do some fine tuning of the position through adjusting the coordinates due to
some distortion of the picture.

Create custom modes in portrait display

Portrait modes are very similar to above, however when taking pictures you need to keep in mind the aspect ratio,
ideally you would take the picture at –°90 to the below so that after the coordinates are entered you can rotate the
video wall using in the settings. This gives a higher quality configuration.

Image position fine-tune

For a simple video wall array, you can use the OSD to change Top Left and Top Right coordinates to fine tune the
position.
For a large video wall or irregular array, you may not see the OSD. It will be more convenient and easier to use the
GAlign PC tool for fine tuning. Please use the [Real Time] mode in the GAlign tool so that you can see the real time
position for easy alignment.
You can also use the [Position] feature in the OSD to adjust the image position for each LCD without changing the
rotation angle and size of the image.
Don’t forget to save the settings into [Option] [Settings] [Profile] [Save] [Index].

User Manual English

▪ In very rare cases, some PCs may not follow the

same EDID settings from the scaler and show
different results. If this happens, please open the PC
resolution settings window and select the desired
output resolution from the PC.

▪ You can choose the PC output resolution up to the

maximum resolution set by the EDID on the scaler.

▪ If you want to a create custom output resolution on

the PC, please select Reduced Blanking timing in the
high resolution output to reduce the output clock.

▪ After you create a custom output resolution on the

PC, go back to the Resolution Selection Window on
the PC to select the desired output timing.

EDID Setup

Selective EDID settings are available on the scaler.
The scaler can support a large range of input signal timings—from SVGA up to 4K. In order to get the best video
performance, the correct EDID information needs to be configured; the aspect ratio in particular needs to be taken in
to account. In a common setup an aspect ratio of 16:9 is used.

▪ Activate the EDID Setting Menu:

[Options]→[Setting]→[EDID]

▪ Use the IR remote control to select the desired EDID.
▪ After selecting the EDID, the PC or media player will

automatically change its output timing settings.

▪ Press the [INFO] key to check if the input timing is set

correctly.

You can also select the EDID manually. The range will be from 800x600 60Hz to 3840x2160 30Hz. Based on the
VESA standards the Horizontal resolution is in a step of (8) pixels and the vertical resolution in (2) pixels. After creating
the EDID, the PC or laptop may still not be able to output the required timings due to hardware limitations or driver
issues. In some cases, you may also need to do a manual selection of the output resolution in the source display
output settings.

Bezel Correction for Preset Display Modes

Bezel Correction

The Scaler features four preset bezel correction settings; Off, 3.5mm, 4.9mm and 1.5%, whilst there is also the option
to create a custom bezel via the custom display mode option.

▪ 3.5mm is based on popular 47” LCD displays
▪ 4.9mm is based on popular 55” LCD displays
▪ 1.5% is based on the use of a conventional TV display

The following table gives an approximate guide for the likely amount of correction based on using the above settings
with different sizes of display; the actual amount of correction required will vary depending upon the size, brand and
model of display used.

In the Bezel Setting section on the front of the unit set dip switch 1 to ON (up) and then power cycle the unit to apply
the setting, this will apply 3.5mm of bezel correction.

If you require 4.9mm set switch 2 to ON (up) and leave all others to OFF (down) and then power cycle the unit. If you
require 1.5% then set switch 1 and 2 to ON (up) and the others to OFF (down) and power cycle.

Another option possible with the 2x2 feature is the ability to invert the top two displays, this is useful if you have a
large bezel at the bottom of your display. To use this, set switch 3 to ON (up) and leave others OFF (down), this will
also provide a 1.5% bezel correction.

Preset Video Wall Configurations

To use one of the preset video walls please set the Dip Switches in the order as defined in the following diagrams
according to your desired configuration. Only the first 6 dip switches are used, dip switches 7 and 8 may be ignored.
Here is an example of how the dip switches are set for Mode 145 with the white squares denoting that the switched
in positions 1, 4 and 5 in the ON (up) position, with 2, 3 and 6 in the OFF (down) position.

Recycling Information

WEEE (Waste of Electrical and Electronic Equipment),
Recycling of Electronic Products

Europe, United Kingdom

In 2006 the European Union introduced regulations (WEEE) for the collection and recycling of all waste electrical
and electronic equipment. It is no longer allowable to simply throw away electrical and electronic equipment. Instead,
these products must enter the recycling process.
Each individual EU member state has implemented the WEEE regulations into national law in slightly different ways.
Please follow your national law when you want to dispose of any electrical or electronic products. More details can
be obtained from your national WEEE recycling agency.

Battery Remark:

Do not put empty batteries in your domestic waste bin as they will not be recycled. Empty batteries can be returned
for recycling at our trade counter or at your local household recycling centre.
The raw materials enclosed in batteries such as Zinc, Iron and Nickel can be reused to a very large proportion. The
recycling of batteries and disused/obsolete electronic equipment is one of the most efficient environment protection
actions you can easily take.

Germany / Deutschland Rücknahme Elektroschrott und Batterie-Entsorgung

Die Europäische Union hat mit der WEEE Direktive Regelungen für die Verschrottung und das Recycling von Elektro­und Elektronikprodukten geschaffen. Diese wurden im Elektro- und Elektronikgerätegesetz – ElektroG in deutsches
Recht umgesetzt. Das Entsorgen von Elektro- und Elektronikgeräten über die Hausmülltonne ist verboten! Diese
Geräte müssen den Sammel- und Rückgabesystemen zugeführt werden! Dort werden sie kostenlos entgegen
genommen. Die Kosten für den weiteren Recyclingprozess übernehmen die Gerätehersteller.
LINDY bietet deutschen Endverbrauchern ein kostenloses Rücknahmesystem an, beachten Sie bitte, dass Batterien
und Akkus den Produkten vor der Rückgabe an das Rücknahmesystem entnommen werden müssen und über die
Sammel- und Rückgabesysteme für Batterien separat entsorgt werden müssen. Ausführliche Informationen zu
diesen Themen finden Sie stets aktuell auf der LINDY Webseite im Fußbereich.

France

En 2006, l'union Européenne a introduit la nouvelle réglementation (DEEE) pour le recyclage de tout équipement
électrique et électronique.

Chaque Etat membre de l’ Union Européenne a mis en application la nouvelle réglementation DEEE de manières
légèrement différentes. Veuillez suivre le décret d’application correspondant à l’élimination des déchets électriques

ou électroniques de votre pays.

Remarque sur les piles et batteries

En tant que consommateur final, vous êtes tenus de restituer toutes les piles et batteries usagées. Il est clairement
interdit de les jeter avec les ordures ménagères ! Les piles et batteries contenant des substances nocives sont
marquées par le symbole ci-dessus. Vous pouvez déposer gratuitement vos piles ou batteries usagées dans les
centres de collecte de votre commune, dans nos succursales ou dans tous les points de vente de piles ou
batteries. Vous respecterez ainsi la loi et contribuerez à la protection de l'environnement !

Italy

Nel 2006 l’unione europea ha introdotto regolamentazioni (WEEE) per la raccolta e il riciclo di apparecchi elettrici ed
elettronici. Non è più consentito semplicemente gettare queste apparecchiature, devono essere riciclate. Ogni stato

membro dell’ EU ha tramutato le direttive WEEE in leggi statali in varie misure. Fare riferimento alle leggi del proprio

Stato quando si dispone di un apparecchio elettrico o elettronico.
Per ulteriori dettagli fare riferimento alla direttiva WEEE sul riciclaggio del proprio Stato.
