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. “Cable boxes, Blu-ray players, streaming media players, video game consoles and more, all use them,” he says.

But 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.

Fortunately, an HDMI switch can solve this problem. So, how does it work? “An HDMI switch starts with multiple input sources to feed a single output,” Prouty says.

But 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. “The second number indicates that you can send the signal to one TV.” So, a 4 x 1 means you can plug four devices into the switcher, and send the signal to one TV.

After consulting an expert and browsing some of the most popular and well-liked models out there, here are some great HDMI switches that will keep you from constantly having to unplug your devices to make room for newer ones.

Jsaux HDMI 2 x 1 Bi-Directional Switch

With the Jsaux HDMI 2 x 1 Bi-Directional Switch, you can simply press a button to switch between two sources, like a laptop or video game console, to one output source, like a TV, computer monitor or projector. The plug-and-play device includes a 3.3-foot HDMI cable (unlike some switches that sell the HDMI cable separately). It can support 4K at a 60Hz refresh rate, as well as 3D video. And since it’s bi-directional, you can also split a signal and send it to two different monitors, but it cannot display images on both monitors at the same time. The switch is compatible with laptops, consoles, Blu-Ray players and streaming devices, and output devices like TVs, monitors and projectors.
