HDMI switches are often hidden away, doing unglamorous tasks in all kinds of industrial, commercial and home electronic equipment.

There are different models of HDMI switches. The simplest and most basic model is the 2x1 HDMI, meaning that there are two inputs and one output. The user is able to switch between two different HDMI sources. For example, the user will be able to have a HD DVD player and a game station hooked up to the switch. The 2x1 HDMI® switch is not highly recommended because the consumer will not have room for future expansion. The 4x1 HDMI switch allows up to four sources, which is recommended. A 5x1 switch is also available for the ultimate expandability. An external HDMIswitch is beneficial for anyone who has a HD monitor and has less than the desired amount of inputs to expand the system. A consumer should consider expandability. A 5-port HDMI® switch is recommended for future expandability, while 2-port HDMI® switch will not.
