In daily life, we will encounter a problem: the computer, PS4, and set-top box must use the high-definition interface of the TV. If you want to convert and use, you need to plug in and out the device. Frequent insertion and removal will not only affect the life of the TV interface, but also burn out thousands of dollars of equipment. The HDMI switcher came into being, and its main function is to switch between multiple input devices. HDMI switchers generally have more than three input ports, one output port, so it is also called X in and out.
HDMI splitter can be seen as a multi-port output distribution device for a class switch. It can distribute one HDMI signal into multiple signals, and the output of these signals is consistent and synchronous. A simple example, the same picture that we see on multiple TVs in the TV store can be achieved through the HDMI splitter. More straightforward: HDMI splitter solves the need to output the content of a signal source to multiple TVs and large screens.
One: How to use HDMI switcher?
According to the brand's use, there are three types of switchers:
(1) Converter itself button switching (most basic usage)
(2) Infrared remote control switching
(3) Bluetooth docking switch (rare)
The specific method is to insert the notebook, set-top box, PS4 and other devices into the input port (input), plug the LCD TV, projector and other devices into the output (output), press the switch button to convert the output signal.
2. The difference between HDMI switch and HDMI splitter
The HDMI splitters and switchers are not only similar in name, but also "longitudinal", but their functions are completely different.
We see that the TV sold in the mall shows the same picture, which is what the HDMI splitter can do: multiple display devices display the same source at the same time. HDMI splitter has more than two output ports, one input port, also called one input X out (as opposed to HDMI switch)
Three: HDMI switch to pay attention to the problem
1. The input port and output port of HDMI cannot be used in reverse;
2. Pay attention to the interface and then turn it on again. Hot swapping may burn the device;
3. Use high-power equipment, please plug in the power supply line (such as PS4), so as to avoid the effect of insufficient voltage.
