An HDMI splitter is commonly used to provide a consistent viewing experience for a larger audience. Whether it's a presentation, promotional video, or gaming experience, it ensures that everyone in the audience can view the same content simultaneously.

In essence, an HDMI splitter eliminates the need for individuals to crowd around a single screen, enabling each person to enjoy an ideal viewing experience as it distributes a single HDMI source to multiple displays.

Can I use dual monitors with an HDMI splitter?

No, an HDMI splitter is not designed to be used for connecting dual monitors.

An HDMI splitter duplicates the same audio and video content from a single HDMI source and sends it to multiple displays simultaneously. This means that all connected monitors will display the same content, mirroring each other.

To use dual monitors with independent displays, connect each monitor directly to separate HDMI outputs on your computer or graphics card. This setup lets you extend your desktop across the two monitors, displaying different content on each screen.

What is the difference between an HDMI switch and a splitter?

An HDMI switch allows you to connect multiple HDMI sources to a single HDMI display. An HDMI splitter, on the other hand, allows you to connect a single HDMI source to multiple HDMI displays simultaneously.


An HDMI switch is used in scenarios where you have multiple HDMI sources (such as gaming consoles, DVD players, or streaming devices) and a single HDMI display, but you want the flexibility to switch between these sources easily.

Whereas, an HDMI splitter is used in situations where you want to display the same audio and video content from a single HDMI source on multiple screens simultaneously. It provides a convenient solution for sharing content with a larger audience.
