- Connect the switcher’s output port to your display device (e.g., TV, projector, monitor).
- Use the switcher’s control mechanism (e.g., remote control, button, switch) to select the desired input source.
- The switcher directs the selected signal from the input source to the output port, which is then transmitted to your display device.
What is an HDMI Splitter?
An HDMI splitter, on the other hand, is a device that allows you to duplicate an HDMI signal and send it to multiple displays simultaneously. This is particularly useful in scenarios where you need to display the same content on multiple screens, such as in home theaters, retail stores, or digital signage applications.
HDMI splitters can be categorized into two types:
Passive HDMI Splitters
Passive splitters are simple, inexpensive devices that use the signal strength of the input source to power the split. They are usually limited to splitting the signal two or three ways and may not support high-bandwidth resolutions or long-distance signal transmission.
Active HDMI Splitters
Active splitters, also known as amplified splitters, are more advanced devices that use an internal amplifier to boost the signal strength. This enables them to support higher-bandwidth resolutions, longer cable runs, and more output ports (often up to 8 or 16).
How Does an HDMI Splitter Work?
The working principle of an HDMI splitter is as follows:
- Connect your HDMI source (e.g., gaming console, computer, Blu-ray player) to the splitter’s input port.
- Connect the splitter’s output ports to multiple display devices (e.g., TVs, projectors, monitors).
- The splitter duplicates the input signal and sends it to each connected display device simultaneously.
