The Roku 3840EU Streaming Stick is a compact, no-fuss streaming device that delivers solid HD picture quality up to 1080p. Part of Roku's 2025 Streaming Stick lineup — the same hardware family as the 3840X released that year — it sits at the affordable end of the range and remains a genuinely practical upgrade for any older TV that still has plenty of life left in it.
TL;DR – The Roku 3840EU Streaming Stick offers snappy menus, a clean and familiar interface, and reliable 1080p picture quality. If you have a perfectly good older TV and simply want to add modern streaming to it without spending a fortune, this is one of the easiest ways to do it in 2026.

Roku in 2026
Roku has been making streaming sticks, boxes, and smart TVs for well over a decade, and the platform has only grown more capable with time. I recently retired a Roku box that had served me faithfully for more than ten years — and the transition to the newer stick format was seamless. The interface is immediately familiar, just noticeably faster. The 3840EU is the European variant of the 3840X, which Roku classifies as a current, fully supported model — meaning it continues to receive OS updates and new channel support rather than being left behind on older firmware.
What's changed most noticeably across Roku's 2025 range is the clear split between HD and 4K tiers. The 3840EU sits firmly in the HD camp: it tops out at 1080p playback and does not support HDR. If your TV is a capable 4K panel, Roku's Streaming Stick 4K or Streaming Stick Plus are the more appropriate choices, both offering Dolby Vision and HDR10+ support. But if your TV is a solid older set that maxes out at 1080p, the 3840EU is the smarter buy — you're not paying for 4K capabilities you can't use.
Fast and Reliable Streaming
Under the hood, the 3840EU runs on an ARM Cortex-A55 processor with 512 MB of RAM — modest on paper, but more than capable for fluid HD streaming and responsive menu navigation. It connects via 802.11b/g/n dual-band Wi-Fi across both 2.4 GHz and 5 GHz bands, which keeps buffering to a minimum on a decent home network.
- HD video over HDMI up to 1080p (1920 × 1080), with upscaling from 720p
- Digital stereo audio over HDMI
- DTS Digital Surround pass-through over HDMI
- Dolby-encoded audio pass-through over HDMI
- USB-C for power
The stick's slim profile is genuinely useful. It plugs directly into your TV's HDMI port and sits flush enough that it won't block adjacent ports — something that chunkier competitors can't always claim. My older Panasonic doesn't have USB power on its HDMI ports, so I used the supplied USB-C to USB-A cable with a standard plug adapter, which worked without any fuss. On newer televisions, the stick can draw power directly from a USB port on the TV itself, removing the need for a separate adapter entirely.
The Remote
The included Roku Voice Remote is straightforward and well thought-out. It paired with my old Panasonic immediately and handles power and volume without needing a separate TV remote. Voice search works reliably for finding content across apps — useful when you can't quite remember which service has the film you're after.
One thing worth noting for anyone upgrading from an older Roku: the built-in headphone jack that appeared on some earlier remotes is gone. Given how widely wireless headphones are used now, it's hard to argue the omission is a real loss, but it's worth knowing if that was a feature you relied on. The remote's battery life has been solid in my experience, and a lost remote finder feature is included for those inevitable moments when it disappears between the sofa cushions.
What's in the Box?
Compatibility and Smart Home Integration
The Roku 3840EU works with Apple AirPlay and Apple Home, Amazon Alexa, and Google Home, so it slots into most existing smart home setups without friction. Casting from an iPhone or iPad via AirPlay is quick and reliable, and Alexa or Google voice commands can control playback if you use either of those ecosystems. It's a broader set of integrations than you'd typically find at this price point.
In the UK, the channel lineup is comprehensive. BBC iPlayer, ITVX, Channel 4, My5, Sky News, Amazon Prime Video, Disney+, Apple TV+, and Netflix all work without issue. Free ad-supported channels through The Roku Channel continue to expand as well, which adds genuine value beyond the subscription services — particularly useful if you want something on in the background without burning through a monthly allowance.
Who Is This For?
The 3840EU makes most sense as an upgrade for an older but functional TV — the kind that still produces a perfectly good picture but was manufactured before smart TV platforms became standard, or whose built-in smart platform has grown slow and poorly supported over the years. Plugging in a current Roku stick effectively gives that TV a modern, actively maintained streaming platform overnight, at a price that's hard to argue with.
If you already own a 4K TV and want to make the most of it, step up to the Roku Streaming Stick 4K instead. But for 1080p sets, the 3840EU is the right tool — quick, compact, and refreshingly simple to set up and live with.
Verdict
The Roku 3840EU Streaming Stick remains a well-executed, no-nonsense device in 2026. It won't win any benchmarks against higher-end streaming hardware, but it doesn't need to. The interface is fast, the picture is clean, the remote is genuinely useful, and the channel selection in the UK covers everything most people watch. For giving a capable older TV a new lease of life, it's one of the more sensible purchases you can make.
In the UK, the 3840EU is available on Amazon. Pick up the Roku 3840EU Streaming Stick on Amazon UK and you'll be streaming within minutes of it arriving.
