Ultra HD Premium

 If you’re sitting there thinking that all these new technologies and acronyms sound confusing then you’d be right. That’s why a group of companies decided to form the UHD Alliance with the expressed aim of defining what technologies should be included in the next generation of TV sets.

The UHD Alliance is comprised of 35 companies including television manufacturers such as LG, Panasonic, Samsung, Toshiba, Sony, Sharp, audio companies such as Dolby, and film and television production companies such as Netflix and 20th Century Fox.

The idea then is that if everyone can agree on what features they think UHD should include then Disney (an example member of the alliance) can produce a movie that Netflix will be able to stream through a Samsung TV, and the eventual image will be exactly what the director at Disney intended.

The result of this alliance was the UHD Premium specification announced at CES 2016. The specification comprises a list of features that should be included in products like TVs and Blu-ray players to ensure maximum compatibility with other content and hardware produced.

Currently, in order to adhere to the UHD Premium specification in 2016 a product must firstly have a resolution of at least 3840×2160. It must be capable of displaying a 10-bit colour depth, allowing for 1,024 shades of each of the three primary colours red, green and blue, as opposed to the 256 allowed by the current 8-bit standard.

A TV must also be capable of displaying pixels at a certain brightness and darkness for HDR purposes (technically this light level is from 0.05 to 1,000 ‘nits’ for LEDs and 0.0005 to 540 ‘nits’ for OLED sets for all you number lovers out there). Adhering to these standards means blacks should look truly dark as opposed to just milky black and whites should really pop.

Finally there are a couple of other more technical requirements such as BT.2020 color representation and a horrendously convoluted high dynamic range rating of SMPTE ST2084 EOTF.

Now that this standard has been defined it should just be a case of checking that your next purchase has the ‘Ultra HD Premium’ logo and not having to worry about your set being incompatible with the slew of 4K content that’s about to emerge over the next few years.

Except of course it’s not that simple.

Samsung and Panasonic are embracing the new standard, with both of their flagship lineups wearing their UHD Premium badges with pride. Sony however have decided to go down a more confusing route and have decided to stick with their internal ‘4K HDR’ label despite their sets all actually meeting the required specification. Philips won’t be using the alliance’s badge, but its sets don’t currently meet the specification anyway.

It’s only natural that while a technology is still emerging these problems will continue to exist, but we hope that soon we’ll be able to recommend looking for a UHD Premium set without reservation. Until the whole industry unambiguously backs the standard however, we’d still recommend you tread carefully to ensure maximum compatibility.

 How expensive is an Ultra HD TV?

 The first wave of 4K TVs were large, really large. Both Sony and LG launched with 84-inch panels, the KD-84X9005 and 84LM960V respectively.

Consequently, they were saddled with price tags in excess of £20,000/$30,000. Not to be outdone, Samsung weighed in with the 85-inch S9 at £35,000/$55,000, clearly aimed at footballers and oligarchs!

However, prices have fallen dramatically as screen sizes have shrunk and brands have predictably embarked on a tit for tat price war. You’ll now find 4K TVs for less than £1000, though we’d encourage you to be careful when choosing one – a 4K resolution won’t necessarily give you a better picture if the processing electronics behind the panel are bad.

Generally speaking, a market-leading 65-inch 4K TV like the Sony KD-65X9005B will set you back a little over $3,500/£3,000. But, choosing last year’s model instead of this year’s is one way of saving a bit of money while still getting a premium picture.
