Show more Factors to consider when choosing the best HDMI splitter When choosing an HDMI splitter, there are several factors to consider to ensure you select the right one for your needs. Here are some key factors to keep in mind:Number of outputs: How many displays do you want to connect to the splitter? HDMI splitters are available with different numbers of outputs, ranging from two to eight or more.Resolution and refresh rate: You will need to make sure that the HDMI splitter you choose supports the resolution and refresh rate of your source device and displays.Audio format: Are you using audio formats such as Dolby Digital or DTS? If so, you need to make sure that the HDMI splitter supports the audio format you want to use.Signal boosting: If you need to transmit the HDMI signal over long distances, consider a powered HDMI splitter. These act as repeaters and boost the digital HDMI signal, allowing you to surpass the normal length limitations of the format.Budget: Consider your budget when choosing an HDMI splitter. Prices can vary depending on the brand, number of ports, and additional features. The more features you want, the more it will cost you. Show more How did we choose these HDMI splitters? Most people never need an HDMI splitter. They hook up their media output to a single TV or monitor and they're done. But there are those who want to make things more complicated, taking a single output and pushing that to multiple displays. Throw in audio formats such as those from Dolby and things can get more complicated.Fortunately, there is an HDMI splitter to suit your needs, from simple to complicated.I have year of reviewing a variety of tech products and accessories ranging from large power stations to tiny thermal cameras for phones. To filter down the whole of the HDMI splitter market to a handful of choices, I've relied heavily on user reviews. There are so many different input and output devices and setups that the crowdsourcing nature of user reviews was the best approach to selecting the best HDMI splitters. Show more What is an HDMI splitter? As the name suggests, an HDMI splitter takes an HDMI input signal from a source device (such as a games console or media box) and splits it into multiple output signals, allowing you to connect multiple displays to a single source device. Show more How long can an HDMI cable be before you need a powered splitter? While there is no maximum length for an HDMI cable specified in the specs, signal attenuation (think leakage) and cable quality normally limits it (with the best quality cables and components, the limit is about 15 meters/49 feet). Show more Can an HDMI splitter be used to connect multiple source devices to a single display? No, a splitter splits the input into multiple outputs. If you want to connect multiple sources to a single display, you need an HDMI switch such as the Anker HDMI Switch that allows two inputs to be switched between on a single display.If you want to get even more fancy and take multiple inputs and mix them, adding things like transitions and even picture-in-picture, you need an HDMI mixer, such as the RGBlink Mini Video Mixer Switcher, which can take four HDMI inputs, along with an audio input, and mix those into one output. Show more Are there alternative HDMI splitters worth considering? Here are a few alternative HDMI splitters for your consideration. While these didn't make it onto the main listing, don't let that put you off because they are very capable units.
