An HDMI switcher selects one source from several connected devices and sends it to a single display, while a matrix switcher routes multiple sources to one or more displays independently. A multiviewer switcher combines switching and scaling to show several sources at once on one screen, which supports source monitoring, presentations, and control in meeting spaces or entertainment venues.

Look for switchers with the source connections your system uses, including HDMI, USB-C, VGA, DisplayPort, or HDBaseT inputs, and verify support for the required video format and resolution. For displays and downstream equipment, choose HDMI outputs for local connections, HDBaseT outputs for longer runs to compatible receivers, or matrix outputs when routing sources to multiple displays.

A multimedia switcher needs 4K support and HDR handling when a system uses high-resolution sources or displays and must preserve compatible image quality, color, and dynamic range. Scaling, EDID management, and HDCP management help match different source and display capabilities, reduce compatibility issues, and support reliable switching in presentation spaces, meeting rooms, classrooms, and entertainment systems.

Multimedia switchers can route video while passing embedded audio or de-embedding it to balanced analog, S/PDIF, or other audio system connections, depending on the configuration. Control options such as Ethernet, RS-232, IR, automatic input selection, and display control help connect the switcher to room-control systems, while HDBaseT, HDMI, USB-C, and network video technologies support distribution to displays and other endpoints.
