The seamless hybrid matrix is generally compatible with the splicing processor function and supports large-screen splicing functions such as ordinary TVs, LCD monitors and DLP.
How to connect the matrix and the video wall?
1. Required equipment:
Signal source: There are no restrictions on the signal source of the video wall on the image. However, from the perspective of the display effect of the video wall, it is recommended that the signal quality and resolution of the signal source be higher.
Generally, the VGA signal is selected. In addition, HDMI and DVI Two kinds of digital signals are also good choices.
Video wall: There are only a few kinds of general video walls, 2×3, 3×3, 3×4, 4×4, 4×6, etc. Then the spliced interfaces of these large screens are 6, 9, 12, 16. 24.
Also, when buying a video wall, you need to pay attention to that: the video wall must contain a built-in video wall processor and a software for a splicing processor.
The function of this processor is to complete the splicing of images between each screen.
Matrix: The video wall processor can realize the image fusion function, but cannot display the video switching function. Therefore, it is necessary to configure a matrix to realize this switching function.
The interface type of the matrix depends on the signal source and the interface of the large screen.
The matrix The number of input terminals depends on the number of signal sources, and the size of the matrix output terminal depends on the size of the video wall, but the output port of the matrix must be greater than or equal to the number of all interfaces of the video wall.

2. Matrix and video wall connection
(1) The signal source output is connected to the input terminal of the matrix;
(2) The output terminal of the matrix is connected to each screen of the video wall;
(3) Each screen in the video wall is connected in series with RS-232 cable (or network cable);
(4) The serial RS-232 cable (or network cable) between the video walls is connected to the last screen and then output to connect to the control computer;
(5) The RS-232 serial port of the matrix is also connected to the control computer with the RS-232 line;
(6) Install the video wall processor software on the control computer, and write the matrix protocol into the video wall control software.

3. Control of matrix and video wall
The built-in software of the processor in the video wall can only control the fusion of images.
We can write the protocol of the matrix into this software, so that we can use this software to control the video wall and matrix at the same time, which is very convenient.
Now let’s take a look at how the iSEMC video wall controller works
iSEMC have both hardware and PC-based video wall controller.
Its support the management of multiple video wall groups (LCD, LED, DLP or projection, etc.) via a single controller.
It can be designed to support up to 4 groups of a video wall with different resolutions and no limitation groups with the same resolution.
You can share the same content across multiple video wall groups.
This means, by acquiring only 1 unit controller, you can use all inputs sources and push to any 4 video wall displays concurrently, without the need to buy an additional controller, making it more cost-effective and convenient.
iSEMC video wall controller’s ability to display source windows in varies.
Some controller allows up to four source windows to be displayed on a single screen, while other controllers allow multiple splitting presented per screen.
The ability to display the same source in multiple windows or multiple outputs at different sizes can be beneficial for very wide video walls servicing segmented work groups in a large room.
iSEMC controller supports up to 4x windows and is split up to 16x on a single display with arbitrary layering, picture in picture, zooming in/out, overlay, stretching and seamless switch whatever you like it.

Matrix
iSEMC's current products cover all HDMI matrix, mixing matrix, audio matrix, audio and video mixing matrix, splicing processor, and decoding matrix etc.. In addition to meeting customers' most basic product needs, we also hope that customers can use our products to improve themselves Project competitiveness and project control ability.
Intelligently control the video matrix. Compared with the ordinary HDMI video matrix, it can not only switch the HDMI signal, but also solve the customer's management problem for large-screen scenes.
This function is not a normal matrix function, but a central control function. The flexibility of the central control lies in its ability to manage on-site signals, and users can control whatever scene they want with one button.
