A monitor cable splitter is a device that allows you to connect two monitors to a single computer using a single cable. This is useful if you want to set up a multi-monitor configuration, or if you want to share a single display with multiple people. There are several types of monitor cable splitters, including HDMI splitters, DisplayPort splitters, and DVI splitters.

HDMI cable splitter

HDMI splitters are used to split the HDMI signal from a computer to two or more HDMI-enabled displays. They are most notably used to set up a multi-monitor configuration with HDMI-compatible monitors. HDMI splitters come in a variety of configurations, including one-to-two, one-to-four, and even one-to-eight.

DisplayPort cable splitter

DisplayPort splitters are similar to HDMI splitters, but they are designed for use with DisplayPort-compatible monitors. They allow you to split the DisplayPort signal from a computer to two or more DisplayPort-enabled displays. Like HDMI splitters, DisplayPort splitters come in a number of different ways and offer additional features such as audio support or the ability to switch between multiple input sources.

DVI cable splitter

DVI splitters split the DVI signal from a computer to two or more DVI-enabled displays. They are similar to HDMI and DisplayPort splitters, but they do not support audio signals. DVI splitters are less common than HDMI and DisplayPort splitters, as DVI is an older interface that is not as used as it used to be.

Other cable splitters

In addition to these types of splitters, there are also splitters available for other types of cables, such as VGA and Thunderbolt. These types of splitters are more scarce, as they are typically used with older or less widely employed technologies. Thunderbolt cable, for example, is almost exclusively used in products by Apple and its splitter is rarer because of that.

It is important to note that not all monitor cable splitters are created equal. Some splitters are of poor quality and may not provide a reliable signal, resulting in distorted or flickering displays. It is recommended to purchase a high-quality splitter from a reputable manufacturer to ensure a stable, reliable connection.
