Best Smart TV for Streaming in 2026: 5 Models Tested
TL;DR - LG C4 OLED (1,399 GBP) for best picture quality. Samsung QN85D (1,099 GBP) for bright rooms and fastest app loading. Sony Bravia 7 (999 GBP) for the widest app library via Google TV. TCL C855 (649 GBP) is the value pick -- Dolby Vision and 1,600 nits at under 700 quid. Skip the Hisense U7N unless budget is tight: WiFi 5 and VIDAA will frustrate within a year.
Why your TV's streaming performance matters more than resolution
Most people buy a smart TV based on screen size and picture quality. Fair enough. But I've spent the past two years living with five different sets, and the thing that actually ruins your evening? A slow, laggy interface that takes 12 seconds to load Netflix. Resolution means nothing when you're staring at a buffering wheel.
A good streaming TV needs three things: a fast OS with broad app support, reliable WiFi 6 (or 6E), and proper HDR format coverage. Get those right and you won't need a separate streaming stick cluttering up your shelf.
We've already covered the best smart TVs overall for 2025 and budget TVs under 500 GBP. This guide focuses specifically on streaming performance -- app speed, codec support, Dolby Vision and Atmos, and WiFi reliability across five price points.
How we tested streaming performance
Each TV ran Netflix, Disney+, Apple TV+, Amazon Prime Video, BBC iPlayer and YouTube for two weeks. We measured app launch times, WiFi throughput at 5 metres and 10 metres from the router (TP-Link Archer AX73), and checked Dolby Vision and Atmos passthrough on every platform. All tests used a 500 Mbps fibre connection.
LG C4 65-inch OLED -- Best for picture quality while streaming
Price: 1,399 GBP (65-inch)
WebOS 24 runs smoothly on the C4's 3 GB RAM. App launch times averaged 3.2 seconds for Netflix and 4.1 seconds for Disney+. Every major UK streaming app is available, though webOS did receive the Paramount+ app about six weeks after Google TV and Tizen.
The real story here is Dolby Vision IQ combined with that OLED panel. Dark scenes in streaming content look phenomenal. No blooming, no crushed blacks. Dolby Atmos passes through to soundbars via eARC without issues.
WiFi 6 pulled 380 Mbps at 5 metres. Solid. At 10 metres through one wall, it dropped to 195 Mbps -- still plenty for three simultaneous 4K streams.
Why would you spend 1,399 GBP when cheaper options exist? Because nothing under 1,000 GBP matches this contrast ratio. That's just the reality of OLED pricing right now.
Samsung QN85D 65-inch -- Best for bright rooms
Price: 1,099 GBP (65-inch)
Tizen OS has matured into a genuinely fast platform. App launches hit under 2.8 seconds consistently -- the quickest in our test group. Samsung's app store covers every UK streaming service, including ITVX, Channel 4 and STV Player.
The QN85D's Mini-LED backlight peaks at 1,850 nits, which means HDR content pops even in a sunlit living room. It supports HDR10+ Adaptive and Dolby Atmos, though Samsung still won't add Dolby Vision. I think that's a mistake on Samsung's part, and it costs them the top spot here.
WiFi 6E delivered 520 Mbps at 5 metres on the 6 GHz band. Impressive. This was the fastest WiFi in our lineup by a clear margin.
Sony Bravia 7 55-inch -- Best streaming OS
Price: 999 GBP (55-inch)
Google TV on the Bravia 7 gives you access to over 10,000 apps. The recommendations engine is genuinely useful once you train it for a couple of weeks. For a deeper look at how platforms compare, check our TV OS comparison guide.
Dolby Vision and Dolby Atmos work across Netflix, Disney+ and Apple TV+. The XR processor handles upscaling of 1080p streams beautifully, adding detail without artificial sharpening.
One gripe: boot time. Cold starts averaged 11 seconds. That's slower than every other TV here. Once running, though, app switching is near-instant.
TCL C855 65-inch -- Best value streaming TV
Price: 649 GBP (65-inch)
Can a TV under 700 quid genuinely compete with sets costing twice as much? For streaming, yes it can. The C855 runs Google TV with 3 GB RAM, so app performance matches the Sony Bravia 7. Netflix launched in 3.4 seconds. Disney+ took 3.9 seconds.
Mini-LED backlighting pushes peak brightness to 1,600 nits. Dolby Vision, HDR10+ and Dolby Atmos are all supported. That's the full set -- something Samsung can't claim at any price.
WiFi 6 managed 310 Mbps at 5 metres and 140 Mbps at 10 metres. Not chart-topping, but more than adequate for 4K streaming which only needs about 25 Mbps.
Build quality feels cheaper than the LG or Samsung. You're trading fit and finish for raw feature parity.
Hisense U7N 65-inch -- Budget streaming pick
Price: 549 GBP (65-inch)
The U7N runs VIDAA OS, which is the weakest platform here for app variety. It's got Netflix, Disney+, Prime Video, Apple TV+ and the main UK catch-up apps. But niche services and newer apps often arrive late or not at all.
Picture quality punches well above its price. 1,500 nit peak brightness, Dolby Vision and full-array local dimming with 500+ zones. For pure streaming image quality per pound, nothing beats this.
WiFi 5 only. That's disappointing in 2026. At 5 metres I measured 220 Mbps, dropping to 95 Mbps at 10 metres. Still enough for 4K, but there's no headroom if multiple devices share the connection.
Which streaming TV should you actually buy?
| Model | Price | OS | WiFi | Best for |
|---|---|---|---|---|
| LG C4 OLED 65" | 1,399 GBP | webOS 24 | WiFi 6 | Picture quality |
| Samsung QN85D 65" | 1,099 GBP | Tizen | WiFi 6E | Bright rooms |
| Sony Bravia 7 55" | 999 GBP | Google TV | WiFi 6 | Widest app library |
| TCL C855 65" | 649 GBP | Google TV | WiFi 6 | Best value |
| Hisense U7N 65" | 549 GBP | VIDAA | WiFi 5 | Tight budget only |
Here's the honest breakdown. If you want the best possible picture from Netflix and Apple TV+, get the LG C4 OLED. If your living room gets lots of daylight, the Samsung QN85D handles glare better than anything else here. Want the smartest OS with the deepest app library? Sony Bravia 7. Tight on budget but unwilling to compromise on HDR? TCL C855 at 649 GBP is remarkable value.
I'd skip the Hisense U7N unless you genuinely can't stretch to the TCL. That WiFi 5 limitation and VIDAA's slower app updates will frustrate you within a year. Spend the extra 100 quid.
One thing every buyer should remember: a TV's processor and RAM determine how long it stays fast. Anything with less than 3 GB RAM will feel sluggish by 2028. Buy for the long haul.
Frequently Asked Questions
Which smart TV OS is best for streaming apps?
Google TV offers the widest app library with 10,000+ apps. Samsung Tizen has all major UK streaming services including ITVX and Channel 4. LG webOS is smooth but occasionally slower to receive new apps. Roku TV keeps things simple with a clean interface and broad app support.
Do I need a 4K TV for Netflix and Disney+?
You don't strictly need one, but 4K content makes up over 70% of new Netflix originals. A 4K TV also upscales 1080p content more cleanly. At today's prices, there's no reason to buy a 1080p set above 32 inches.
Is it better to use a streaming stick or built-in apps?
Built-in apps on 2025-2026 TVs with 3 GB+ RAM perform well. A streaming stick like the Chromecast with Google TV (29.99 GBP) or Amazon Fire TV Stick 4K Max (54.99 GBP) makes sense only if your TV is older than 3 years or runs a sluggish OS with under 2 GB RAM.
