With the advent of the intelligent display era, LCD splicing screens are used in many occasions, such as video surveillance or meeting content, promotional videos, data, etc. In addition to the signals displayed in surveillance video surveillance, such as meetings, displays, etc. Sometimes, computer signals are displayed . Sometimes, in order to display more content more conveniently, and multiple computer inputs, how to achieve it?
With the advent of the intelligent display era, LCD splicing screens are used in many occasions, such as monitoring or meeting content, promotional videos, data, etc., in addition to monitoring the signals displayed in video surveillance, such as meetings, displays, etc.
1. How to achieve it?
As we all know, the LCD splicing screen is composed of multiple small screens, such as 3*3, 3*4, 4*6, etc. At this time, 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 big screens, and at the same time want to display another screen on the other screen or other screens, at this time, there are two computers enter.
At this time, 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 rarely used. At present, HDMI matrix is mainly used in the market, such as 4 in and 4 out, 4 in and 8 out, 8 in and 16 out, 16 in and 32 out, etc. In refers to the number of computer folds, and out refers to the number of large-screen splicing screens.
2. On which occasions will multiple computers be used for screens?
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, computers are usually connected 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 a company's exhibition hall, some promotional videos are usually played, and some static company profiles, product profiles, etc. are also displayed. Then you need multiple computers to achieve this.
Large-scale data display platforms have become more and more important, and data analysis is often used for comparison. At this point, we can display different content on multiple computers at the same time on the LCD splicing screen, 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.
