Video distribution products are named after what they do with sources (inputs) and displays (outputs). Once you count both, the right category is usually obvious.
Splitter: one to many
A splitter takes one input and shows the same picture on several outputs, for example 1 input to 4 or 8 displays. Typical uses are classrooms with several screens, retail windows and waiting rooms. Splitters with EDID control help keep every display at a resolution all screens can show.
Switch: many to one
A switch lets several sources share one display, and you choose which one is shown. Selection can be manual, automatic when a new source is connected, or remote by IR or RS-232.
Switch-splitter: many to many, same picture
A switch-splitter combines both: pick one of several inputs and send it to all outputs at once. It suits rooms where the presenter changes but every screen should show the same thing.
Matrix: anything to anywhere
A matrix lets each output choose its own input independently. Use it when different screens must show different sources, such as control rooms or venues with multiple zones.
Three checks before you buy
- Resolution: every device in the chain must support the resolution you want to run.
- HDCP: protected content needs HDCP support on the distributor and displays. 4K streaming sources commonly require HDCP 2.2.
- EDID: when displays differ, EDID management tells the source which format to send. See our EDID and HDCP guide.
