The KS8000 runs on the VA panel and, like Samsung’s other SUHD TVs this season, it provides an extremely impressive black level measurement of 0.015 nits with the neighborhood dimming off and 0.001 nits with it in the reduced setting. The TV can be bright, easily hitting our target of 120 nits and, as stated in the HDR section, delivering a peak brightness of over 1,300 nits. Due to this fact the on/off contrast ratio with the neighborhood dimming off was 8,000:1 and the ANSI contrast ratio was 2,800:1, both which are impressive for an TELEVISION.

The uniformity was also impressive, with this review sample delivering a straight backlight that was free from any evident clouding or bright edges and corners. We also didn’t notice any dirty screen effect and overall this is an outstanding performance from the Samsung. The off-axis viewing angles weren’t bad either, although the KS8000 runs on the VA panel so they should never be likely to be ideal. Nonetheless they did appear much better than many other TVs that people have seen this season.

The neighborhood dimming was excellent and even in the reduced setting the KS8000 could deliver deep blacks and bright whites, without crushing shadow detail or clipping highlights. There is a pleasing insufficient haloing, specially when sat directly before the TV but there is more haloing as you moved off axis, especially in the vertical plane. But also for standard dynamic range content we generally found the neighborhood dimming to be impressive, even though the KS8000 uses edge lighting with LEDs along underneath. This limitation was more clear with high dynamic range content, where in fact the increased brightness and the neighborhood dimming on the high setting could sometimes reveal haloing or brighter edges. This is particularly true of letterboxed films, where sometimes we’re able to see brighter edges because of a particular image on screen.

The motion handling on the KS8000 was best for an LCD panel, with none of the stuttering or frame dropping that people have observed on Samsung TVs during the past and it handled our motion tests perfectly. We measured the motion resolution round 300 with Auto Motion Plus off and the entire 1080 lines with it on, which is what we’d expect. However using the Auto Motion Plus features does introduce smoothing that may rob images of their film-like quality, so we generally left it off. But also for sport-based content, which is shot on video, there may be room to experiment and pick a setting that best suits you.

When it found watching standard definition content the KS8000 did a exceptional job of deinterlacing and upscaling the image. The video processing on the Samsung was excellent and, because of the accurate greyscale and colour space, the results were very watchable regardless of the clear drop in resolution. After we moved to Full HD things found a gear, with nature programmes looking wonderful and certain scenes in Stranger Things looking particularly impressive. Naturally after we moved to Blu-ray we saw another pick-up in performance with this usual test discs all looking wonderful on the KS8000.

As we’ve mentioned the neighborhood dimming did an outstanding job of delivering great blacks and dynamic range, without introducing halos or overtly crushing shadow detail. A normal test Blu-ray such as for example Gravity looked marvellous and regardless of the frequent sight of bright objects against black backgrounds, the backlighting was rarely obvious unless we plunged the area into total darkness and even they weren’t that obvious. Due to this impressive performance, the KS8000 could deliver an excellent picture, whether or not we were watching standard or hi-def content.

Finally we ran through various HDR content as soon as again the KS8000 delivered the products with images that took full good thing about the increased resolution available. When watching films just like the Revenant and Deadpool that truly used a 4K digital intermediate, the amount of detail was impressive. The make use of 10-bit video depth helped remove banding in the image and the wider colour gamut revealed more saturated and realistic colours. The KS8000 also took good thing about the HDR grading to provide images that had great impact.

The high peak brightness meant the highlights could really pop, whilst the blacks remained deep but there is still a good amount of detail in the shadows. The KS8000 were able to properly tone-map a popular scene from Pan and overall it performed perfectly with HDR content. However, as we mentioned earlier, edge lighting isn’t well suited for HDR and sometimes the Samsung struggled with certain scenes and the limitations of the technology were revealed through bright edges. That said, the KS8000 was still with the capacity of among the better HDR performances that we’ve seen this season and when coupled with its SDR performance it creates for an excellent all-round TV.
