HDMI Splitters

An HDMI splitter sends one source to several screens at once, handy for digital signage, a bank of displays or feeding a second telly from the same box. This AV:Link range runs from compact one-in-two and one-in-four units to a one-in-eight splitter and a two-by-four matrix switch with IR remote, with the four-out, eight-out and matrix models handling 4K at 60Hz so the picture stays sharp.

What an HDMI splitter does

An HDMI splitter takes one source and sends the same picture to more than one screen at the same time. Plug your box, player or computer into the input, then run a lead from each output to a separate display. It is a tidy way to show the same feed on a row of monitors, a pair of tellies in different rooms or a screen above the bar as well as one behind it.

One in, several out

This range steps up through the common layouts. A one-in, two-out unit feeds a pair of screens, a one-in, four-out handles a small bank, and a one-in, eight-out drives a wider spread. Each output mirrors the source, so every screen shows the same thing rather than a different channel.

Matrix switching

A two-by-four matrix switch goes a step further, letting you route either of two sources to any of four outputs. With the bundled IR remote you can change which input lands on which screen without unplugging anything, which suits a setup where the feed needs to swap through the day.

Picture quality and power

Built around HDMI 2.0, the four-out, eight-out and matrix models pass 4K at 60Hz, so a sharp source stays sharp on the far screens. The compact one-in, two-out unit is bus powered, drawing what it needs from the HDMI connection rather than a separate plug, which keeps the cabling behind your stand simple.

Choosing the right one

Count your screens first, then pick the output number to match, leaving a little headroom if you might add a display later. For a fixed wall of screens a straight splitter is enough; if you need to change sources on the fly, the matrix switch earns its place. Free UK delivery over £99, worldwide shipping.

Frequently Asked Questions

Will a splitter show different channels on each screen?

No. A splitter copies one source to every output, so all the screens show the same picture. To send different feeds to different screens you would need a matrix switch with separate sources.

What is the difference between a splitter and the matrix switch?

A plain splitter has one input and several outputs, all showing the same source. The two-by-four matrix takes two inputs and lets you route either one to any of its four outputs, with an IR remote to change the routing.

Do these pass 4K?

The four-out, eight-out and two-by-four matrix models handle 4K at 60Hz over HDMI 2.0. Your source and screens need to support 4K as well for the full resolution to come through.

Does the small splitter need its own power supply?

The one-in, two-out unit is bus powered, so it draws power from the HDMI connection rather than a separate mains plug. The larger units are mains powered.
