1. VGA matrix, VGA signal is commonly known as standard definition signal and analog signal. The VGA video signal is used for input and output, which is the function of copying and amplifying the analog SD signal. So it can be computer VGA, video recorder VGA, video box VGA, DVD VGA, look for all VGA signal control. Link the large-screen display splicing method, through the same signal source to the video wall, each large screen displays the same signal, and the large-screen software is used to splice the images to achieve the effect of the screen, so it is suitable for monitoring security, with a small budget Some conference systems or hotels.
2. DVI matrix, DVI signal is commonly known as high-definition signal and digital signal. DVI high-definition video signal is used for input and output, which is represented as a function of copying and amplifying high-definition digital signals. So it can be all DVI high-definition digital signals, video recorders and computers basically have this signal output, so it can be spliced and displayed on the video recorder and computer screen, which can be used for conference systems, surveillance security, exhibition hall display, hotel, KTV, etc. Where there is a high demand for video effects, the premise is that there is no audio transmission requirement.
3. HDMI matrix, the difference between it and DVI matrix is that it has audio transmission function, it has all the functions of VGA matrix. It is suitable for scenes that require high-definition video effects and audio transmission.
Four, splicing screen control processor
The above three are all spliced and displayed in units of screens. What to do when you need to open a window at will, open more display windows to play, then you need to control the processor on the splicing screen. It can open windows at will, with any size, location, overlap or overlap, select display channels at will, set welcome words, rolling captions, and splicing freely. It contains three different signals: VGA, DVI, HDMI, and can be used by selecting the corresponding splicing control processor according to the video signal output port of the back-end equipment. When contacting the relevant LCD splicing screen manufacturer, you can consult in detail as needed.
Five, high-definition network video matrix
To input the network signal, connect the network cable through the switch, and the output signal can be VGA, DVI, HDMI. You can open the window at will, add cameras at will, and use the standard keyboard after adding. The whole process does not need to install software and be equipped with computer operation, embedded software, stable and reliable.
Six, mixed matrix
It is a product specially designed for a variety of video signals on the video wall. It can be VGA, HDMI, DVI, network signal, BNC analog signal, mixed for splicing display, it can be two-two-mix, three-three-mix, and the project can be mixed at will. This kind of matrix is suitable for the solution requirements of complex systems, such as changing old solutions, adding new equipment solutions, etc. This kind of hybrid matrix is now widely used to meet the needs of different functions.
