A 4K HDMI splitter is a device that allows you to split one HDMI input signal into multiple HDMI output signals. It’s often used to distribute high-quality audio and video content from a single source, such as a Blu-ray player or gaming console, to multiple displays, such as TVs or monitors.

The term “4K” refers to the resolution of the video signal being transmitted. 4K resolution is a term used to describe video with a horizontal resolution of approximately 4,000 pixels. This means that a 4K splitter is capable of transmitting high-quality video content with a resolution of up to 3840 x 2160 pixels.

A 4K HDMI splitter can be useful in many settings, such as in homes, offices, conference rooms, and entertainment venues where multiple displays need to show the same content simultaneously.
