In this article, we’ll cover everything you need to know about HDMI splitters, including what they are, the important features to look for, and how to connect one to your system. So, whether you’re a tech newbie or an experienced user, you’ll be able to get up and running with an HDMI splitter in no time.

What is an HDMI Splitter?

An HDMI splitter is a device that takes an HDMI signal from a source device, such as a computer, game console, or Blu-ray player, and splits it into multiple outputs, allowing you to connect multiple displays to a single source.

The splitter has one HDMI input and multiple HDMI outputs, depending on the model. For example, an HDMI splitter with four outputs will allow you to connect four displays to a single HDMI source.

Why Would You Want to Split an HDMI Signal?


There are many reasons why you might want to split an HDMI signal. For example, you may have a single HDMI source, such as a gaming console, that you want to connect to multiple displays in different rooms.

Or, you may want to split the signal from a video wall processor to display on multiple screens in a conference room or a public space. An HDMI splitter is an easy and affordable way to achieve this.

What is the Difference Between an HDMI Splitter and an HDMI Switch?

While an HDMI splitter splits one signal into multiple outputs, an HDMI switch allows you to switch between multiple sources and output the selected source to a single display.

For example, if you have a TV with only one HDMI input but multiple HDMI sources, such as a cable box, a gaming console, and a Blu-ray player, you can use an HDMI switch to connect all the sources to the switch and output the selected source to the TV.

How to Choose HDMI Splitters?

When choosing an HDMI splitter, there are a few things to consider:

1. Number of Outputs: The first thing to consider is how many displays you want to connect to the splitter. HDMI splitters are available with different numbers of outputs, from two to eight or more.

2. Resolution and Refresh Rate: The HDMI splitter you choose should support the resolution and refresh rate of your source device and displays. If your source device supports 4K resolution and 60Hz refresh rate, for example, make sure the splitter can handle that.

3. Audio Format: Some HDMI splitters support advanced audio formats such as Dolby Atmos or DTS: X. If you want to enjoy high-quality sound on your displays, make sure the splitter supports the audio format of your source device.

4. Compatibility: Check the compatibility of the HDMI splitter with your source device and your displays. Some HDMI splitters may not work with certain devices or may have compatibility issues.

How to Connect an HDMI Splitter?

Connecting an HDMI splitter is easy. Here are the steps:

1. Connect the HDMI cable from the source device to the input of the splitter.

2. Connect HDMI cables from the splitter’s output ports to the displays.

3. Power on the source device and the displays.

4. The signal should automatically split and display on all connected displays.
