1. Introduction
1.1 Introduction to SW-VDYWALL
The KanexPro SW-VDYWALL is a Video Processor with 4 DVI input and 4 DVI output, which enables you to configure
to either a 2x2 Video Wall or create a 4x1 Multi-viewer. This high-performance processor supports image overlapping
and output scaling function to your specific needs. Compliant with HDCP and supports EDID management. The Video
Wall does not require all 4 sources and 4 displays to be connected in-order to work, one can connect and select
between 1 to 2 inputs to 4 outputs such as Apple TV or Blu-ray to 4 displays. Included software, using RS-232
connection to a computer, will help you set up all the different layout configurations such as PIP, POP, switching
functions, resolutions and save & recall functions.
The built-in scaler supports various PC & HD resolutions up to 1920x1200. The embedded scaler converts an input
signal to match the native resolutions of output displays, up-scaling if needs to be. The scaler is also manually
adjustable through front-panel buttons; featuring selectable output settings of up to 1920 x 1200@60Hz.!Ideal for
operation centers, military installations, shopping malls and airports where demand for high-resolution 4x4 video wall is
critical.

Figure 5-6 Main Functional Zones
Note: When in any one of the five modes (4x full screen zoom-in mode, 3x zoom- in mode, matrix switching mode, PIP mode, and
POP mode), please notice the following information.
1) When in distribution display mode or in matrix switching display mode, it is able to set the resolution of any single output by
checking the option box full mode, and also able to set as a whole resolution. But not able when in any one of the other four
modes.
2) It is not able to set the correspondences between the inputs (Channel input switch) and the four outputs.
3) It is not able to set the overlay hierarchical relationship of a single input channel or to set the hierarchical relationship of all input
channels.
4) When in PIP display mode or in POP display mode, it is able to set the output display state. But not able when in any one of the

times, as shown in Figure 6-1.
Detailed Operations: While the software is running normally, click on the button , the display mode area on the software
interface will show the output display mode of any one of the input channels. The four images on the displayers make up a whole
image same as the input image.
The buttons are used for choosing the image of any one input channel to the outputs.
5.4.2 3x Zoom-in Function
Function: To split an input signal to three parts, one of them is rotated 90 degrees, and then to display on the displayers one to one.
Generally there will be no output image on the first output channel (the displayer just shows a blue screen), and the images on the
second, third and fourth displayers (All are rotated 90 degrees) make up a whole image with the input image. Shown in Figure 6-2.

SW-VDYWALL
Detailed Operations: While the software is running normally, click on the button , the display mode area on the software
interface will show the output display mode of any one of the input channels. The three images on the displayers (The second, third
and fourth outputs) make up a whole image same to the input image. The first displayer shows a blue screen.
The buttons are used for choosing the image of any one input channel to the outputs.
5.4.3 Matrix Switching Function (Full Displaying)
Function: To choose one or all the input images of the four input channels and then output to the four output displays. Shown in
Figure 6-4. The default correspondence between the four displayers is like.
Detailed Operations: While the software is running normally, click on the button , the display mode area on the software
interface will show the output display mode of any one of the input channels. The image of each displayer is the same with the
corresponding input image. And click on the button , the display mode area on the software interface will show the output
display mode of any one of the input channels. The output images are the same with each other and also the same with the input
image. Shown in Figure 6-5.
5.4.4 Picture in Picture (PIP) Displaying
Function: SW-VDYWALL is able to present all the input images of the four channels on a single screen. It means that while the
screen is showing the main video, any of the other three input images (Had been compressed) also can be showed on this screen.
That makes users be able to monitor other input images. In one word, it means to overlay the main video and the deputy images
together.
Detailed operations: While the software is running normally, click on the buttons, , , or , the
display mode area on the software interface will show the display effect of all the four input channels. The images (at most three are
complete) on any one displayer are made by the four input images.
The buttons are used for checking the output image of any one channel.
The display effects are showed in Figure 5-7 to 5-11.
