4K TVs - Ultra HD
4K TVs - Ultra HD
4K, Ultra HD, 4K Ultra HD – call it what you want – the 'four times HD' TV technology has finally arrived with some purpose in 2013, with more 4K TVs, the first broadcast trials and even some content. And with CES 2014 around the corner, we're expecting yet more noise about the next-gen TV resolution.
So, what's it all about? On this page we'll run through the basics, get you up to date on 4K TVs and 4K content, take a look at the 4K Ultra HD TVs on the market – and how the sizes and prices are – hopefully – coming down.
You will also find a round-up all of our 4K TV reviews to date. We'll be keeping this page updated as your one-stop for everything 4K Ultra HD, so check back if you're in the market to buy a 4K TV...
4K TV resolution
Officially 4K resolution is 4096 x 2160 pixels. However, in order to shoe-horn this higher resolution video on to a normal 16:9 picture format for a TV, the resolution has been altered to 3840 x 2160 – still four times the total number of pixels on a Full HD 1080p screen (1920 x 1080).
In order to take full advantage of 4K Ultra HD you will of course need a compatible TV, source and the necessary content packing those all-important extra pixels. And that's where it gets messier: while we're seeing the first 4K TVs going on sale, the issue of content – when we're going to get it, how we're going to play it – is much trickier.
4K content
There's no denying that 4K Ultra HD is very much a fledgling format. Native content is very hard to come by for consumers anywhere. Sony has come closest to offering a solution in the US, with the launch of its 4K Ultra HD Media Player, which went on sale in July for $700.
The FMP-X1 server comes pre-loaded with ten 4K films, has a 2TB hard drive, HDMI and USB connections and connects to your network via an Ethernet connection.
And it sounds like you'll need that wired connection for accessing Sony's 4K download service. Officially called Sony Video Unlimited 4K, the download service is due to launch later this year and promises to be the world's first and only network service to give access to a constantly updated library of 4K films and TV shows.
