Samsung UN55KS9000

The UN55KS9000’s headline attraction is that it has all the specifications needed to deliver - on paper, anyway - a genuinely premium high dynamic variety knowledge for a mid-variety value.

These specifications incorporate a higher brightness output of beyond 1000 nits and a massive colour variety delivered by Quantum Dot technologies that covers far more than 90% of digital cinema’s DCI-P3 standard. 

The UN55KS9000 differs from the models that sit below it by supporting much more localized controls of its edge LED lighting method and slightly a lot more potent motion processing. 


Samsung has sensibly stepped away with the UN55KS9000 from the chunky design of a lot of of its 2015 TVs in favor of a slimmer, far more minimalist look.

The narrowness of the screen frame is echoed by a slender rear that stands in stark and, for us, welcome contrast to the extended depth developed by Samsung’s curved TVs. The addition of a gleaming metallic trim and centrally mounted polished aluminum desktop stand creates a really premium feel, too.

The UN55KS9000’s connectivity is largely robust, with highlights of four HDMIs, 3 USBs, and Wi-Fi network connectivity. The only disappointment is that the only headphone connection choice is Bluetooth.

Smart Television (Tizen)

Samsung’s latest Tizen-primarily based Smart TVs make it a lot less difficult than their predecessors did to swiftly get to interesting content material. This is since it introduces a new second deck of contextual content hyperlink icons above the original deck introduced in 2015.

Accessible apps are headlined by 4K and HDR versions of Amazon and Netflix, YouTube, Hulu and Playstation Now. 

HD/SDR Performance

At the heart of the UN55KS9000’s considerable SDR thrills is a superb black level response. Dark scenes advantage from black colors that actually look black - particularly if you use the neighborhood dimming technique that lets different segments of the TV’s edge-mounted LEDs deliver diverse amounts of light.

What’s more, in SDR mode this localized LED manage causes hardly any undesirable light pollution about bright objects, even when those bright objects seem against close to-black backdrops. This is a uncommon accomplishment in the edge-lit LED globe.

The outstanding black levels aren’t achieved at the expense of shadow detailing, and contribute to a terrifically rich color performance. This richness is joined by gorgeously subtle color toning, which aids to emphasize the clarity of one of the sharpest, most detailed UHD photos I’ve observed.

Whilst the UN55KS9000 is at its greatest with native UHD sources, it is no slouch at upscaling HD. Blu-rays and HD broadcasts appreciate a clear sharpness boost whilst simultaneously obtaining inherent noise magically removed.

All that mentioned, just avoid setting the TV’s sharpness larger than about 25 with upscaled HD if you don’t want regions of fine detail beginning to ‘glow’.

4K/HDR Efficiency

Each and every other aspect is noteworthy, but it’s with HDR that the UN55KS9000 most tends to make its mark. Particularly effective is its ability to hit brightness peaks above the 1000 nit level utilized when mastering most existing HDR sources. This instantaneously ‘sells’ the effect of HDR versus SDR, and aids Samsung’s Television resolve subtle tonal detailing in the brightest locations that ‘flares out’ on significantly less bright TVs.

The UN55KS9000 also does a stellar job of delivering the wide colour ranges that are element of the Ultra HD Blu-ray HDR encounter, with this richness holding up for the duration of dark scenes much better than usual with LCD TVs, too.

The UN55KS9000 is not only excellent, although, at displaying off the most dynamic aspects of HDR and wide colour gamut sources. It’s also got sufficient finesse in its HDR toning to handle significantly less explosive image regions like skin and cloudy skies with genuine sensitivity and naturalism. The huge range of color tones obtainable to the UN55KS9000 in HDR mode joins forces with the native UHD resolution to deliver superbly detailed images.

The only factor that reduces the clarity is some pretty pronounced motion judder when showing 4K content, and some color banding in HDR skies.

1 other concern is that you can occasionally see vertical bands of light running down the image around bright HDR objects that appear against dark backgrounds. This dilemma disappears if you turn off local dimming, but doing this reduces the exceptional black level efficiency and the intensity of HDR’s brightness peaks


Despite its enviably trim bodywork, the UN55KS9000 produces a quite potent, expansive audio overall performance. In a best planet there’d be a lot more bass to flesh out explosions, gun fire and the like. But ideal sound and very thin TVs seldom go together, and by the requirements of thin TVs normally the UN55KS9000’s audio is properly above average.


The UN55KS9000 sets the appropriate tone immediately with its trim, glamorous style, and builds on that with a killer combination of a Tizen-driven wise Television technique, a native UHD resolution and high dynamic variety playback.

Its photos deliver on this HDR prospective with levels of brightness and color you just do not get anyplace else for the exact same funds - though it’s a star with normal dynamic variety, also.There is a price tag to spend for such dynamic photos in the appearance of some backlight clouding flaws during dark HDR scenes, but in the end the pros far outweigh the cons.

This report is based on the smaller, UK version of the Television – the Samsung UE49KS8000 – that TechRadar published in September 2016
