SUHD

What sets the SUHD range apart from the lower-ranging ‘UHD’ sets is the use of nano-crystal technology: a thin film layer of tiny crystals from the display panel that emit light in various colours according on their size, which allegedly offer 64x more colour expression and 3. 5x more brightness than typical tellies. Fancy figures, indeed. But will it be all talk and no trousers? It seems not.
Across resolutions (Ultra HD to DVD), the Samsung produces a intoxicating picture that’ll surely silence any sceptics. With 4K, it’s like looking by using a newly-washed window. Play Marvel’s awesome Daredevil and each of this 8. 3million pixels is put to good use, filling the screen’s handsome real estate investment with pin-sharp outlines, potent contrast and eye-popping (yet truth-telling) colorings - more subtle and nuanced than those of its nearest thing rival, the LG 55UF950V. It’s all too easy to slip into nose-to-screen viewing habits.

Sony

                   
Should you prefer a picture with good colour, you've come to the right area. This Sony is wonderfully realistic, serving up vibrant reds, distinct blues and inky blacks on its edge-lit LED LCD section. The clean whites could have a touch more punch, but that's our only real complaint. Viewing angles are great too - not something that is certainly said about Sony's 2013 sets - with colours staying just as vivid as you move aside.
Stick on a Blu-ray and you'll be treated to some sort of crisp, smooth, detailed picture, and even standard-def TV and Videos look great. You might want to spend a little time tweaking the settings though - as is frequently the case with modern TVs, you'll get the best results by turning off the many (usually unnecessary) 'Reality Creation' and 'noise reduction' processes then starting again.
If 3D floats your boat, the W829B is on the active variety and comes with two pairs of specs from the box. You lose a little brightness and might notice a bit smearing at times, but overall the picture remains superb with three dimensions.

LG4k

LG possesses finally given its Magic Remote buttons, so you don’t should faff about with two remotes. The single remote has shortcut keys, a scrolling wheel, and a gyroscope to control the on-screen cursor. Of which pointing-and-clicking will divide opinion, but it works.
You can also speak commands towards TV: a genial, casual request to switch channels was effectively and swiftly transcribed, and then it did it. *applause*

LG4k.

When LG launched its first OLED screen recently - the we fell in love. It was everything we’d expected them to be from OLED: deep, luscious blacks and punchy, bright colours. Nevertheless it wasn’t 4K.
This TV is. And that marriage of 4K and OLED is what our wildest telly-tech dreams are made from.
You’re all familiar with 4K’s pixel-packing four-times-full-HD resolution by currently. But what’s the deal with OLED? Unlike normal LCD screens that need backlighting to generate a picture, OLED pixels generate their own light and colour, while a pixel turns off, it goes totally pitch black, and it is usually right next to another pixel that’s pumping our pure, excellent white.
That means contrast can be breathtakingly brilliant, but in addition that images are brighter and punchier overall. LG takes it a step further by having a fourth white pixel to the standard RGB model for more accurate colours.
So OLED goes blacker than plasma and brighter than LCD - throw pin-sharp 4K resolution into the mix and you’ve got the most beneficial screen we’ve ever laid our eyes on.
The particular contrast is unbelievable: black scenes are so deep and dim we’re mesmerised. Next to that, whites shine brilliantly, and shades pop and punch without looking overdone. It’s 55 inches regarding pure TV heaven.
There’s no swallowing of detail like inside previous OLED screens, either. There’s clarity and subtlety within shadows, while colours are lush and deep. 4K was made being watched on this screen: the picture is crisp,

the actual detail sky high, and there’s a sense of depth because of the deeper blacks.
You don’t just have to watch 4K to have the benefit, though. Blu-rays and full HD channels are upscaled deftly, keeping that punchy contrast, and crisp definition. We can barely tear our eyes from the explosions of colour in Pacific Rim, while the comfortable, natural hues of The Imitation Game are inviting.
We’ve many seen Gravity in 3D. But have you seen Gravity with 3D and OLED? Not only is LG’s passive 3D technological know-how comfortable, but the vast expanse of deep space looks so pitch black that any of us feel like we’re getting physically sucked in. One caveat: motion needs a little help, so have a tinker with the TV’s settings.
