Available in 2, 3, 4, 5 and 8-port models, these devices can be daisy chained or cascaded to achieve an even greater configuration. Also available in matrix models with sizes such as 2 x 2, 3 x 2, 4 x 2, 4 x 4 and 8 x 8, these devices eliminate the hassle of disconnecting and reconnecting the sources. Working on simple plug and play functionality, a user just needs to plug the input sources to the input ports on the switcher which in turn is connected to the display devices using the HDMI cable. Since it uses only a single HDMI cable to relay the video and audio signals, it also reduces the clutter associated with using multiple cables.
