7 Best TV Accessories at Argos Worth Buying Right Now (2026)

No piece of advice we give gets more consistent feedback than this: buy a soundbar. Modern flat TVs sacrifice audio quality for thinness — there simply isn't room for decent speakers. The Samsung HW-B550 fixes this with 360W total output, a dedicated wireless subwoofer for deep bass, and a Dolby Audio decoder.

The HW-B550 connects via HDMI ARC (Audio Return Channel) — a single cable that carries audio from your TV while also controlling the soundbar with your TV remote. Setup takes under five minutes. The improvement in dialogue clarity, bass response and overall immersion is dramatic on any TV in our top five, but particularly the LG C3 OLED and Samsung Q80C.

If you have an older TV without a smart platform — or one with a slow, outdated interface — the Fire TV Stick 4K Max is the fastest way to modernise it. Plug it into any HDMI port and you get Alexa voice control, 4K HDR streaming (including Dolby Vision and HDR10+), access to every major UK streaming service, and blazing-fast Wi-Fi 6E connectivity.

Even owners of newer smart TVs sometimes prefer it: the Fire TV interface is snappier and more regularly updated than some built-in smart platforms, and Alexa integration lets you control compatible smart home devices directly from your TV remote.

Wall-mounting your TV instantly elevates the look of any room, saves space, and lets you achieve the perfect viewing angle. Sanus is one of the most trusted names in TV mounts, and their full-motion bracket allows tilt, swivel, and extension — so you can angle the screen exactly where you need it from any seating position.

It's compatible with any TV using a standard VESA mounting pattern (check your TV's manual — all five of our reviewed TVs are compatible), and includes a built-in cable management channel to keep wires hidden and tidy.

If you're connecting a PS5, Xbox Series X, or a 4K Blu-ray player to an HDMI 2.1-capable TV (like the LG C3 or Samsung Q80C), you need a certified Ultra High Speed HDMI 2.1 cable to access 4K at 120fps and eARC audio return.

Many TVs and consoles ship with only standard HDMI cables that cap bandwidth at 18Gbps (HDMI 2.0). The Belkin Ultra High Speed cable is certified at 48Gbps — the full HDMI 2.1 specification — and supports 8K/60Hz, 4K/120Hz, and Variable Refresh Rate pass-through. At under £20, it's an essential investment if you've spent hundreds on a high-refresh TV.

A smart plug lets you control your TV and related devices — soundbar, games console, streaming stick — with voice commands, schedules, or your phone. If you have a Fire TV Stick or any Alexa-enabled device, you can say "Alexa, turn off the TV" and have everything power down simultaneously.

Beyond convenience, smart plugs help reduce standby power consumption. A typical TV in standby uses 1–5W continuously — small individually, but across all household devices it adds up. Setting a sleep schedule on your smart plug ensures devices only draw power when you need them.

Google's own streaming device runs the full Google TV platform — identical to what you get built into Sony and TCL TVs — on any screen via HDMI. It's faster, smoother and more capable than most smart TV platforms found on older screens. Google Assistant integration is seamless, and the Chromecast functionality lets you cast content from your phone or laptop in seconds.

It's a particularly good upgrade for anyone with a Hisense A7NQ or TCL C655K who wants Google TV's superior interface without buying a new TV.

An often-overlooked but genuinely important accessory for anyone who's just spent £500–£1,100 on a TV. A surge-protected extension lead protects your TV, soundbar, console and streaming devices from voltage spikes caused by lightning strikes or power grid fluctuations.

It also provides the extra sockets you'll need once your TV setup grows. A typical setup — TV, soundbar, console, streaming stick, smart plug — can easily need 5–6 sockets. Masterplug's surge-protected lead is widely stocked at Argos and represents excellent value for the protection it offers.
