1. How can it be achieved?
Everyone knows that the LCD splicing screen is composed of multiple small screens, such as 3*3, 3*4, 4*6, etc. At this moment, we can regard the entire large screen as a computer monitor. If you only need to display a large screen, you only need to match a distributor.
If it is also a 3*3 spliced LCD splicing screen, if we want to display one screen on one of the large screens, and at the same time we want to display another screen on the other screen or on the other screens, at the moment, it is two Computer input.
At this moment, a signal switching device is needed to control the display position of the image to achieve arbitrary switching, and the device is a matrix. The matrix is divided into three types according to different interfaces: HDMI matrix, DVI matrix and VGA matrix, including HDMI and DVI matrix. It is a high-definition signal, and the VGA matrix is used very little. Currently, HDMI matrix is mainly used in the market, such as 4 in 4 out, 4 in 8 out, 8 in 16 out, 16 in 32 out, etc. In refers to the number of computer folds, and out refers to the number of large-screen splicing screens.
2. How many computers will be used on the screen on which occasions?
Various computer inputs are often used in conferences, monitoring, exhibition halls, data analysis and other fields. For example, in a company's conference room, during a meeting, the computer usually connects to display some word and ppt documents. At this time, some data on another computer also wants to be transmitted to the LCD splicing screen at the same time, for a comparison, a matrix is needed for exchange, so that the signals on the two computers can be distributed.
Secondly, like the company's showroom, usually some promotional videos will be played, but some static company profiles, product profiles, etc. will be displayed, then you need a few computers to achieve.
Large-scale data display platforms have become more and more important, and data analysis is often used for comparison. At this moment, we can display different content on the LCD splicing screen and on multiple computers at the same time, so that we can clearly see the data without switching pages, and it looks more convenient.
Therefore, if you want multiple computer signals to be displayed on the LCD splicing screen at the same time, you only need to install an HDMI high-definition matrix, and the number of computers is not limited. You only need to match the interface according to the number of inputs and outputs.
