Dans la vie quotidienne, nous allons rencontrer un problème: ordinateurs, PS4, set-top boxes need to use the high-definition interface of the TV, and if you want to switch to use, you must plug and unplug the device. Frequent plugging will not only affect the life of the TV interface, but also burn thousands of yuan of equipment. The HDMI switcher came into being, and its main function is to switch multiple input devices. HDMI switchers generally have more than three input ports and one output port, so it is also called X in and out.
The HDMI distributor can be regarded as a multi-port output distribution device of a switch. It can distribute a HDMI signal into multiple signals, and the output of these signals has consistency and synchronization. As a simple example, the same picture displayed by multiple TVS that we see in the TV store can be achieved through the HDMI distributor. To put it more bluntly: HDMI splitters address the need to output content from one signal source to multiple TVS and large screens.
How to use HDMI switcher?
According to the use of the brand owner, the use of the switcher has the following three categories:
1.Switch the button of the changer itself (basic usage)
2. Infrared remote control switch
3. Bluetooth docking switch (less common)
The specific practice is to plug the notebook, set-top box, PS4 and other devices into the input port (input), the LCD TV, projector and other devices into the output (output), press the switch button to convert the output signal.
La différence entre le commutateur HDMI et le répartiteur HDMI
The HDMI splitter and the switch not only have similar names, but also very similar “looks”, 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 achieve: multiple display devices display the same signal source at the same time. HDMI splitter has more than two outputs, an input port, also called an in X out (contrary to HDMI switcher)
Problems to pay attention to in the use of HDMI switchers
1, HDMI input and output can not be used in reverse;
2, pay attention to the interface is plugged in before turning on. Hot swap may burn the device;
3, the use of high-power equipment, please plug in the power supply line (such as PS4), so as not to affect the effect of insufficient voltage.
