An HDMI splitter provides the capability to project the same image to multiple screens, which is handy if you’re, say, hosting a big sports viewing party across several TVs or a head-to-head gaming event on dual monitors. In some cases, you still might run out of places in which to plug in your HDMI cables. Fortunately, an HDMI splitter/switch can solve this problem.
So, how does it work? First, the terms splitter and switch tend to be used interchangeably. However, Greg Scott, a Minnesota, Minnesota-based author and cybersecurity professional, says there’s a difference between an HDMI splitter and an HDMI switch.
“An HDMI splitter takes one source input and splits it to feed multiple outputs; this is useful if, say, a monitoring system needs to send output to multiple monitors,” he explains. “An HDMI switch starts with multiple input sources to feed a single output.” A switch essentially gives you more HDMI inputs to flip between (ideal if your TV doesn’t have many), while a splitter mirrors content across multiple screens.
But Scott says splitters and switches can also support multiple inputs and multiple outputs. “For example, a 2 x 2 splitter splits a signal from either source 1 or source 2 to destinations 3 and 4,” he says. “Or maybe a 2 x 2 switch offers a choice to display content from sources 1 and 2 on either or both destinations 3 and 4.” That’s why some items are called HDMI switches/splitters.
After consulting an expert and scouring the web for a range of popular and well-regarded models, we’ve picked out a variety of great HDMI splitters that will make it easy to mirror content throughout your home.
Orei HDMI 1 x 2 Splitter
$29.99 $14.99 at Amazon
The compact Orei HDMI Splitter is ideal for outputting one source to two different displays. It’s compatible with laptops, Roku, Chromecast, Xbox 360 and Xbox One, PS4 and PS4 Pro and several other sources. The company advises against using cables over 30 feet if you want the best picture, and a USB cable is included. The device can support 4K x 2K resolution at a 30Hz refresh rate. However, it cannot be used to extend monitors and does not extract audio from speakers.
Avedio Links 1 x 2 Splitter
$16.99 $15.89 at Amazon
If you want to project the same image to two different screens (for example, to the TV in the living room and also the TV in the bedroom), the Avedio Links HDMI Splitter is an inexpensive way to do it. You can connect your laptop, gaming console, media player, etc., and that image can be displayed on either two TVs, or perhaps one TV and one computer monitor, or one projector and one monitor, or two monitors. However, the same image will be displayed on both output sources as a mirror image. The splitter supports 4K at a 60Hz refresh rate (which is ideal for many TVs, though it won’t take advantage of the smoother 120Hz in newer models). Both a high-speed HDMI cable and USB cable are included.
