HDMI and USB switchers let installers route video from multiple computers or other sources to one or more displays, with some matrix models sending different sources to separate outputs. Models with USB hubs or USB routing can switch connected cameras, microphones, speakerphones, touch displays, keyboards, and mice between host computers, supporting presentation, collaboration, and video conferencing setups.

A standard HDMI and USB switcher typically selects one source from multiple inputs and sends it to a single display or output, with some models also switching USB connections between host computers and peripherals. A matrix switcher supports multiple inputs and outputs, allowing different sources to route to separate displays or destinations at the same time, which suits rooms with multiple screens, remote endpoints, or flexible presentation needs.

Compare support for 4K/UHD resolution, 60 Hz refresh rates, HDR, chroma subsampling such as 4:4:4 or 4:2:0, and the HDMI data rate needed by your sources and displays. Also review signal-management features such as HDCP 2.2 compliance, EDID management, automatic input selection, 4K-to-1080p scaling, and HDBaseT extension when remote displays or USB devices are part of the installation.

HDMI and USB switchers with HDBaseT can carry video, audio, control, Ethernet, and USB signals over category cable for connections up to 330 feet, supporting remote displays, cameras, microphones, speakerphones, and other peripherals. Matrix configurations with multiple inputs and outputs, along with compact end nodes and USB hubs, help integrators scale AV systems across meeting rooms, classrooms, and other presentation spaces.
