If you've ever juggled game consoles, streaming boxes, Blu-ray players, and a TV with not enough HDMI ports, you know the frustration. HDMI splitters and switches are the unsung heroes that keep your setup tidy and functional. A splitter duplicates a single HDMI source to multiple displays, while a switch lets multiple sources feed one display. Together they solve the classic "too many devices, not enough ports" problem, and they can transform a messy media corner into a streamlined system that actually behaves. Think of them as traffic controllers for your video signals—if you pick the right one, everything flows smoothly.
Before clicking “buy now,” it helps to know which specs actually matter. Not all HDMI splitters and switches are created equal. Some are fine for casual streaming, while others will handle 4K HDR gaming at high frame rates. Let’s break down the essentials so you can pick a device that works for your gear, your room, and your budget.
Resolution support is one of the first things to check. If you own a 4K TV or a 4K projector, make sure the unit supports 4K at 60Hz—or at least the refresh rate your device needs. Gamers should look for 4K at 60Hz with low latency, and if you’re chasing silky-smooth motion on next-gen consoles, aim for devices that explicitly support 120Hz at lower resolutions or 4K at 60Hz. Always check whether a product advertises HDR and whether it supports the HDR standard your devices use.
HDCP (content protection) can block playback if your splitter or switch doesn’t support the right version. For streaming services and Ultra HD Blu-rays, HDCP 2.2 support is a must. EDID handling affects how devices negotiate resolution and audio formats; good splitters/switches manage EDID intelligently so you don’t end up with downgraded video or missing Dolby Atmos. If you need ARC or eARC for audio return to a soundbar or AV receiver, confirm support—these features aren’t universal.
Count the ports and think about placement. A 1x2 or 1x4 splitter will route one source to two or four displays respectively; a 3x1 or 5x1 switch gives several sources to one screen. Active units that require external power tend to be more reliable over longer cable runs, while passive units are compact and plug-and-play. Metal housing and well-spaced ports make life easier behind a TV or in a rack. Also check whether the device includes a remote or auto-switching capabilities—those little conveniences can save you from crawling behind the sofa.
Now that you know what to look for, where should you shop in the UK? Below are reputable retailers that stock a wide range of HDMI splitters and switches, from budget plugs to pro AV hardware. I’ve included what they’re best at so you can match the store to your needs.
Currys is a reliable place to start for mainstream HDMI splitters and switches. They stock entry-level units suitable for streaming and basic gaming, plus mid-range models that support 4K and HDR. The advantage here is convenience: online options and local store collection make returns and testing easier. If you prefer seeing gear in person, Currys is a steady middle-of-the-road choice.
Argos often carries compact, affordable switches that are perfect for living rooms and small setups. They’re especially handy when you need a quick replacement or a simple 3-in-1 switch that won’t break the bank. Argos models tend to be user-friendly, and their click-and-collect network is convenient if you want immediate pickup.
John Lewis tends to stock higher-quality consumer electronics and often carries brands that prioritize build and compatibility. If you want a nicely boxed unit with better support and a solid warranty, John Lewis is a great bet. They cater well to customers who want a blend of performance and peace of mind.
For audiophiles and home cinema enthusiasts, Richer Sounds is a go-to. They offer professional-grade HDMI equipment, expert advice, and selection tailored to serious setups. If you’re pairing a high-end amp, surround system, or projector, their staff can help match splitters and switches to your AV chain.
Amazon UK probably has the widest selection, from budget brands to premium pro AV products. The benefit is user reviews—read them carefully to spot issues like handshake problems or flaky switching. Prime shipping gets gear fast, and the marketplace structure means you can find niche brands that other stores don’t stock.
Scan and eBuyer cater more to the tech-savvy buyer. If you want a switch with advanced features—like RS232 control, matrix switching, or rack-mountable units—these retailers are worth browsing. They’re often the first to list pro-level converters, distribution amplifiers, and hybrid HDMI/DisplayPort gear for custom installs.
AO.com offers consumer-friendly options similar to Currys but often with competitive pricing and delivery. Specialist online shops that focus on AV or home cinema can be excellent for obscure models and for getting precise specifications. If you’re building a multi-room system, consider a specialist who understands both the tech and the installation challenges.
Brand choice matters more in HDMI gear than in many other categories. Established names tend to get firmware updates and provide better support for thorny issues like HDCP handshakes. Below are brands frequently stocked by UK retailers worth your attention.
Brands such as Atlona, Orei, Kramer, Gefen, and Lindy make professional-grade splitters and matrix switchers. For consumer-focused gear, look at Techole, FosPower, and ViewHD for affordable, reliable options. Monster and AudioQuest offer premium cables and some distribution products. If you’re unsure about a brand, check user forums or retailer reviews to see how well updates and support are handled.
Here’s a simple way to decide: if you want to show the same signal on multiple screens, buy a splitter. If you want to connect several sources to one screen, buy a switch. If you need both features—say, multiple consoles to multiple TVs—you might need a matrix switcher, which is essentially a switch and splitter rolled into one. Think about how you use your devices and plan a little for future upgrades so you don’t outgrow your choice in a year.
For gamers who juggle a console and a PC, a 3x1 switch with fast switching and minimal input lag is ideal. For a small retail display or a home cinema that needs the same video on a projector and a TV, a 1x2 or 1x4 splitter works well. For conference rooms or classrooms that need flexible routing, a matrix switcher is worth the extra investment. Match the device to the scenario like picking the right tool from a toolbox.
Installing HDMI splitters and switches is usually straightforward, but a few pitfalls can turn a quick job into an afternoon of fiddling. Below are practical tips I wish I’d known the first time I set up a multi-device system.
Use high-quality HDMI cables and keep runs reasonable. For most consumer setups, cable runs under 20 feet (approximately 20 ft) are safe with standard high-speed HDMI cables. Over longer distances, consider active cables or HDMI extenders that use Cat6. Avoid cheap, long cables that claim high specs but fail in real-world use; bad cables often masquerade as device faults, so swap them first when troubleshooting.
Active splitters/switches with their own power supplies usually give more reliable performance, especially when feeding multiple displays or long cables. If a passive device struggles, a powered unit or an inline signal booster can resolve handshake and dropouts. Keep power bricks accessible—tucking them behind a wall or tight cabinet can make troubleshooting painful.
Not every living room needs a premium matrix switcher. If you stream in HD and use one TV, a budget switch does the job. But if you demand 4K HDR, Dolby Atmos, or low-latency gaming at 60Hz+, invest in higher-quality gear. Premium models have better EDID management, firmware updates, and often better build quality. Think of budget units as a comfortable pair of trainers and premium units as bespoke shoes—they both get you to the finish line, but one will feel and last better.
Buy with the future in mind. HDMI standards evolve, and 8K is already on the horizon for some products. If you plan to upgrade to a new console or TV soon, target devices that support the latest HDMI versions, ample bandwidth, and features like eARC. Future-proofing is a balance—don’t overspend on features you’ll never use, but avoid cheap gear that forces replacement in a couple of years.
If you want a few quick recommendations: for simple living-room use, a 3x1 switch supporting 4K@60Hz and HDR from a reputable brand is a safe bet. For a small multi-screen display, a powered 1x4 splitter with HDCP 2.2 support will save headaches. For pro or custom installs, look for matrix switchers with RS232 control and robust EDID management. Buy from stores that match your confidence level—big retailers for convenience, specialist sellers for complex builds.
Buying an HDMI splitter or switch in the UK doesn’t have to be a chore. With a clear idea of the resolution and audio features you need, a plan for cable runs, and a retailer that suits your shopping style, you can upgrade your setup with confidence. Whether you’re a casual streamer, a die-hard gamer, or building a multi-room system, the right device is out there—and now you know how to find it.
Conclusion: Choose gear that fits your current needs but leaves a little room to grow. Test cables first, prefer powered units for long runs, and shop retailers that match your comfort level—high-street convenience or specialist advice. With the right splitter or switch, your home entertainment will stop fighting you and start performing like it should.
