Best 4K TV 2014

Everyone wants an Ultra HD 4K TV! Yes, okay, we all know there isn't much 4K source material to properly showcase the stunning picture quality, but Netflix has at least started to offer 4K content.

There could also still be a 4K Blu-ray format later this year, and before you know it there'll be test transmissions and perhaps even a 4K TV channel from Sky or the BBC.

It's all about future-proofing, though there's slightly more to it than that; some of the first batch of Ultra HD TVs pump out best-ever Blu-ray images, thanks to some wonderfully adept upscaling tech. The birth of 4K could also lead to the re-birth of 3D – it just looks so much better at this higher resolution.

The big stumbling block – as always – is money, but already there are relative bargains to be had and, better still, some sumptuous designs stuffed with new innovations. The race for 3840x2160 pixels is on.

Samsung UE65HU8500

This curved TV sets new benchmarks

Out earlier this year, the sexiest 4K TV currently available has to be the Samsung UE65HU8500. Measuring 65-inches across it's curved panel, it offers stunning visuals unlike any other TV we've tested. It makes a mark right away with its curved screen, immediately standing out from last year's uniformly flat 4K crowd. Its connections are much more up to 4K speed than those of most of last year's Ultra HD sets too, including HDMI 2.0 ports and support for the new H.265 4K video codec that's being used by Netflix (and likely others) for the delivery of 4K content.

Toshiba 58L9363

The 4k TV that changed everything

4k will catch-on when it becomes affordable, and that era started with the release of the Toshiba 58L9363.The undisputed cheapest Ultra HD TV out there in the UK, it's three-inches wider than the 55-inchers from LG, Samsung and Sony – and its announcement actually caused the prices of those three to be hugely slashed. Using the Active Shutter 3D system, the 58L9363 is Toshiba's second-generation 4k TV after 2012's 55ZL2 glasses-free telly than also sported a 3840x2160 resolution. Its smart TV options – called Cloud TV – aren't as slick as on the pricer brands, but its CEVO 4k engine upscales HD-to-4k, and this remains the cheapest way to get eight million pixels into your life.

LG 55LA970W

Drop-down Sliding Speakers, but it's Cinema 3D that wins-out

LG isn't the only manufacturer to take advantage of the need for chunkier 4k panels to simultaneously beef-up audio – Sony is also playing that game – but the Korean company's effort is super-slick. Yes, it's got eight million pixels, but what we really love about the 55-inch 55LA970W is its motorised drop-down, 50W-rated Sliding Speakers. They literally appear from within the TV's undercarriage at the touch of a button, and are accompanied by a subwoofer on the rear. Back on picture the 55LA970W uses a a 100Hz-rated panel that also boasts LG's own NANO Full LED backlighting and a Tru-ULTRA HD Engine for upscaling SD and HD to UD quality. The 55LA970W naturally sports LG's own Cinema 3D 'passive' 3D system, which is arguably where Ultra HD succeeds most obviously.

Samsung UE55F9000

4k works its magic with Active Shutter 3D, too

Having eight million pixels instead of two million helps 'passive' or Cinema 3D systems immeasurably, but what about the Active Shutter 3DTVs from Samsung? It's a company that's stubbornly stuck to this increasingly unpopular technology, but UE55F9000 proves that it's not misplaced loyalty; we're talking a cracking visual density and – compared to passive 3D TVs – a startling level of extra resolution and detail. Meanwhile, native 4K content looks so good it's silly, while upscaled HD looks crisp and clean. Although it uses a now standard edge LED lighting system, the UE55F9000 also boasts local dimming tech for better contrast. One of the slimmest Ultra HDTVs around, the UE55F9000 also has the best smart TV platform.

Sony KD-55X9000A

Booming sound system almost steals 4k's thunder

By creating this widest-ever 55-inch TV Sony may have inadvertently blotted-out the very reason for the the penchant for small (ish) 4k TVs, but the KD-55X9000A is nevertheless a timely reminder of how crucial sound is to higher-res movies. Native 4k looks pin-sharp and upscaled Blu-rays – both 2D and 3D – have never looked better, but it's those built-in side-mounted Magnetic Fluid speakers, complete with two subwoofers, than are the biggest delight. With only slightly less wow factor than its big sister, the far pricier KD-65X9005A, the KD-55X9005A, which uses passive 3D specs, is one of the best value Ultra HD tellies around. The catch is that there's no HDMI 2.0 compatibility and now HEVC either, meaning it's not a future-proofed option. Read: Sony KD-55X9000A review

Philips 65PFL9708

Is this the best value 65-incher?

Philips TVs and always all about detail – and the 65-incher, in that sense, is no mould-breaker. However, in every other regard the 65PFL9708 is a one-off. The smallest in Philips' flagship 9000 Series, the 65PFL9708 comes armed with a HEXCore processor that feeds Philips' own Ultra Pixel HD Engine, which is built around an ULTRA Resolution upscaler. It cleverly splits each pixel in HD source material into four, then intensifies them to find additional colour and detail. Also featuring an ambient light sensor that noticeably deepens blacks are purifies whites in high ambient light levels, the 65PFL9708 also includes Ambilight. Philips promises us that a small converter box will be available soon to upgrade the 65PFL9708 to HDMI 2.0. Read: Philips 65PFL9708 review

Panasonic TX-L65WT600

Panny's power-play includes HDMI 2.0

Aside from being one of the best-looking TVs around, Panasonic's debut Ultra HD telly has some work to do. With the manufacturer having finally dumped plasma as a screen technology, it needs to make Ultra HD work – and the high-end TX-L65WT600 does just that. The only Ultra HD telly we know of with HDMI 2.0-rated inputs from the get-go, the future-proof 65-inch TX-L65WT600 can accept and play 4k progressive pictures at 50Hz. It's also got a Display Port 1.2a input, which can take 4k feeds from a PC, and 4k Intelligent Frame Creation, which can pan at up to 1,200 frames per second with all sources. Oh, and did we mention its 4k THX Certification?

Sony KD-65X9005A

The ultimate all-in-one home cinema

Just like the early flat TVs – and the smaller, far more affordable 55-inch version, the KD-55X9000 – this 65-inch stunner from Sony uses forward facing stereo speakers either side of the 4k display, though the glossy design sees a single sheet of edge-to-edge glass across the front. Native 4k has absolute fidelity and image depth on the KD-65X9005, and Blu-ray is upscaled so well, but it's those Magnetic Fluid speakers that we're really taken by. Adding immense depth and stereo imaging as pin-sharp as the onscreen antics, the KD-65X9005A becomes so much more than just another large screen telly – it's perhaps the ultimate all-in-one home cinema product. It's another watershed moment, though at this price it will remain out of reach of most of us. Read: Sony KD-65X9005A review

LG 84LM960V

A visual knock-out, this pixel-dense display is a pricey plaything

One of the UK's first Ultra HD TVs initially released last Christmas, LG's monster-sized 84-inch 84LM9600 is next-gen TV tech writ large – and an equal to the Sony KD-84X9005. With Ultra HD content, the TV's fine detail performance is phenomenal, and the pixel-packed panel does a grand job of remapping Full HD too. It breathes startling life into contentious 3D, doing away with the resolution loss seen on regular passive 3D screens. The immaculate solidity of its pixel-dense images is beguiling, whether it's Ultra HD or Blu-ray on the screen, while the beefy sound system adds another dimension to the best-ever picture quality. It's big – so big it likely won't fit through your front door – but as a proof of concept the 84LM960V is well ahead of its time. Read: LG 84LM9600 review

Sony KD-84X9005

An incredibly ambitious bid for 84-inch greatness

The biggest of Sony's cutting-edge X9005 Series of Ultra HD TVs, the 84-inch KD-84X9005 is a challenger – albeit it in a niche – to the LG 84LM9600. With its ultra-powerful 4k X-Reality PRO video processing, the KD-84X9005 is a gloriously ambitious TV. Native Ultra HD pictures look unbelievably good, and it's no stretch to say that it's capable of hosting the best picture quality ever known. But it's not just about pixels; the levels of detail, colour accuracy, clarity and depth are astounding, too, and the set's upscaling of HD images is enormously impressive. Its 3D images are a revelation, with the 4K resolution combining with passive 3D technology to jaw-dropping effect. As well as injecting new life into the ailing 3D concept, the KD-84X9005's built-in Magnetic Field speakers and subwoofers are extraordinarily potent for a non-separates system.
