So, how does it work? “An HDMI switch starts with multiple input sources to feed a single output,” Prouty says.īut what do the numbers (for example, 4 x 1 or 6 x 1) mean? “The first number indicates how many devices you can plug into the switcher,” Prouty explains.

“Cable boxes, Blu-ray players, streaming media players, video game consoles and more, all use them,” he says.īut what happens if your TV or monitor doesn’t have enough HDMI inputs to accommodate all of your cool devices? No one wants to keep reaching behind or on the side of the TV or monitor to disconnect one device so you can then connect another one.įortunately, an HDMI switch can solve this problem. HDMI switches can increase the functionality of compatible electronic devices, and you probably already have tons of them in your home. “High-definition multimedia interface (HDMI) has become the go-to cable for anything HD,” explains Carl Prouty, a technologist at Abt Electronics in Glenview, Illinois.
