Since HDMI was introduced in 2004, it has become the dominant player in the audio-visual interface market. Today, nearly all devices related to audio-visual transmission feature HDMI interfaces,
leading to the development of corresponding transmission equipment. Among these, HDMI splitters (so-called distributors) and HDMI switches are the most common types, and users often have trouble distinguishing between the two.
In this article, we will introduce what an HDMI splitter and HDMI switch are and explore the disparities between them, covering their functionalities,
applications, and distinctive audio-visual specifications. We will also highlight essential considerations when using these devices.
Fundamental Difference Between HDMI Splitter and HDMI Switch
If you're unfamiliar with the audio-visual tools, you can start by determining the type of device you need. Based on the number of source and display devices,
the common HDMI tools can be categorized into one-to-many, many-to-one, and many-to-many. You can see the diagram of two HDMI tools above:
Can HDMI be split into two screens?
The answer will be yes, and you may need a splitter. An HDMI splitter can split one audio-visual signal into many and distribute them to multiple displays.
Depending on your needs, you can purchase HDMI splitters with 2, 3, 4, or more output ports. For example, the function of HDMI splitter 1-in-2-out is to distribute video to two displays.
How do I connect two devices to one HDMI input?
If your TV does not have enough HDMI ports, you may need a switch. An HDMI switch can transmit audio-visual signals from many source devices to your display,
TV, etc. This way, you can connect two or more devices to an HDMI switch and connect the switch to the one HDMI port on your display.
After learning the essential difference, let's explore the functions and applications of HDMI splitters and HDMI switches.
What Does an HDMI Splitter Do?
HDMI splitters, so-called HDMI Distributors, split the source signal into multiple signals and distribute them to separate displays, even across different rooms or areas,
enabling simultaneous viewing for multiple audiences.
HDMI splitters are not solely intended for professional audio-visual services. Smaller-scale HDMI splitters for TVs or personal use are available on the market. Moreover,
if they support HDMI splitter extended display, they can offer multi-screen functionality for personal computers.
What Does an HDMI Switch Do?
Conversely, when you have multiple audio-visual sources demanding simultaneous attention, you will need to switch between different screens at the display end.
This is where HDMI switches come into play, and there are various subtypes.
HDMI switches dedicated to pure audio-visual transmission are suitable for home entertainment systems, allowing users to switch between different audio-visual devices using a remote control easily.
They are also well-suited for the professional surveillance industry, offering the seamless switching between multiple camera views. When paired with HDMI multiviewers or related equipment,
HDMI switches allow for simultaneous viewing of recordings from four or dozens of monitoring devices.
Additionally, HDMI switches with KVM functionality allow users to control devices connected to the switch using a mouse and keyboard at the display end.
Additional Features of HDMI Switches/Splitters
HDMI splitter and switch devices sometimes come with various functionalities to meet specific needs and application scenarios:
HDMI splitters and switches with signal extension features empower users to extend the reach of their signal transmission well beyond the standard 15-meter limit of HDMI cables.
Signals can be extended to over 100 meters or more over cables such as network cables, ensuring compatibility with a wide range of display devices.
HDMI switches equipped with KVM functionality go beyond mere audio-visual signal transmission. They also facilitate the transmission of control signals, including mouse and keyboard inputs, to the front-end devices.
This feature allows users to seamlessly operate multiple devices simultaneously.
Traditional HDMI switches require manual switching to view content from different sources. HDMI multiview switches, however, offer multi-screen splitting functions that can divide a single display
into quadviews, each showcasing content from various sources simultaneously. Moreover, if HDMI multiviewers support mouse roaming functionality, users can effortlessly control content from four
computer devices while watching them simultaneously.
