What is an HDMI splitter?

In the field of audio and video, a splitter is a device that can divide one audio and video signal into multiple outputs of the same audio

 and video signal. According to different interfaces, the more common splitters mainly include: HDMI splitter, DVI splitter, VGA splitter, 

SDI splitter, etc.; According to the number of distribution interfaces, the common distributors mainly include: 2-port distributor, 

3-port distributor, 4-port distributor, 8-port distributor, 16-port distributor, 24-port distributor, 32-port distributor, etc. 

The 1×4 HDMI splitter front and rear panel ports shown in the figure below.

How does an HDMI splitter work?

The working principle of the HDMI splitter is to copy 1 audio and video signal into multiple audio and video signals in real time through the 

chip lossless and output, the process of copying is similar to copying files on the computer, but this is synchronized in real time, so that we 

can see the synchronized video picture and synchronized audio on multiple monitors. Generally, the distributor will be equipped with a 

high-quality power adapter to ensure that the machine can work normally and stably; Do not use an inferior power adapter at will, as this 

may cause a series of problems such as signal interference and unstable operation of the distributor. When using the HDMI splitter, it is best

 to connect the ground wire screw interface reserved on the splitter with the ground wire to ensure the safety of the machine.

The role and installation of the HDMI splitter

The function of the HDMI distributor is mainly to output the important picture to multiple displays in real time, so that people can get the 

latest information in a timely manner, of course, it can also be used in TV stores, monitor stores, used to display the same audio and video, 

convenient for users to buy. For example, high-speed rail stations and airports have a large flow of people, so in order to facilitate passengers 

to obtain the latest train information, flight information, etc., the same information will be displayed in multiple conspicuous places.

Taking the 1×4 HDMI splitter as an example, the system connection diagram is as follows:

After the HDMI splitter is installed, you can adjust the brightness and contrast on the splitter to adjust the image clarity of the remote display device 

to the same effect as the local one. HDMI splitter has the advantages of small size, fast efficiency and effective cost saving. Its use is also very simple, 

as long as you find the interface marked with input, connect it with the signal host with the corresponding cable, connect it to the ground wire, 

power supply, and other interfaces are signal output interfaces, and you can connect a few monitors if you want to connect a few monitors, 

which is easy and efficient to operate.
