Product Information

As a result it’s going to have to do at least one special thing if it’s going to stand out from the crowd. Its entirely healthy obsession with trying to give you the maximum 4K and HDR bang for your buck may well win it plenty of fans, though. As the UK bit of its name suggests, the Toshiba 50UK4D63DB is only available in the UK, with no similar variants to be found in other territories. The former enables the TV to take advantage of extra scene-by-scene data delivered by Dolby Vision sources, while the latter sees the TV taking on the challenge of creating a soundstage capable of delivering at least a sense of Dolby Atmos’s object-based approach to sound.

Presentationally this actually works very well, resembling Samsung’s Eden platform in the way it limits its home screen appearance to a couple of icon decks at the bottom of the screen.The 50UK4D63DB even enjoys a bit of promoted video processing courtesy of Toshiba’s TRU Picture Engine. A great example of what we’re talking about can be seen in the sequence in It where Georgie chases his ill-fated boat down a rain-soaked street. We don’t find that the screen needs help often from its motion processor, even with action-packed 24fps movies, but if you do find the screen’s native judder a touch too much, the Tru Flo processing’s Low setting does a decent job of taking the edge off without creating the dreaded soap opera effect (or too many unwanted digital side effects).

Helping its HDR performance out is the way the TV retains better black levels despite its brightness than we customarily find on budget TVs.The really startling thing about the 50UK3163DB’s HDR performance is that as well as delivering bright HDR shots with an impressively high level of baseline brightness, it still has enough brightness headroom to shift up another gear for the sort of ultra-intense highlights that really make HDR shine. It’s worth noting here that while the 50UK4D63DB always looks better than expected with dark HDR (and, actually, SDR) scenes, it benefits more than usual from receiving Dolby Vision signals whenever you can find them. There’s no faded or wan look to skin tones, while heavily saturated hues don’t tip over into gaudiness or unnaturalness despite looking more vibrant than might have been expected.
