An HDMI Switch helps you switch between multiple HDMI signals. The main purpose is to easily shift from one stream of data to the other with ease. The HDMI Switch has multiple streams of input while having only one stream of output. One of the best HDMI Switches currently available on the market is the Kinivo 550 BN. An HDMI Splitter is the exact opposite of an HDMI Switch. The splitter takes in a single stream of input while providing multiple streams of output data. The output data can then be sent to multiple devices, in this case, multiple HDMI devices. An example of the HDMI Splitter is the Techole 4K HDMI Splitter. Both the Switch and the Splitter are different from the HDMI Matrix switch, which combines the switch and the Splitter functionality. One of the best HDMI Matrix Switch is the BZBGEAR  BG-UHD-44M18G.
