In depth: 4K TV and UHD: Everything you need to know about Ultra HD


Update: We’ve had 4K gaming on the PC for a while now, but this year at E3 2016 4K took off in a big way with the announcement of Microsoft’s 4K Xbox code-named Project Scorpio. Alongside the Scorpio, Microsoft also has the Xbox One S which will upscale HD content to 4K as well as play Ultra HD Blu-ray discs. Microsoft isn’t the only console manufacturer with a 3840 x 2160 resolution on its mind, however. Sony also has a 4K console up its sleeve which it’s calling PlayStation Neo. It’s never been a better time to make the jump to 4K.

4K Ultra-High Definition will define the future of television.

Nothing makes a television manufacturer happier than the ability to slap a bigger number on their shiny new product, and with 4K (or Ultra HD, or was that UHD?) they’ve hit the jackpot.

At its most basic, 4K describes the resolution of your TV set (or the amount of pixels used to make up an image), but it is also increasingly being used to describe a combination of a whole host of new features which together are ushering in a new era in image quality.

4K was everywhere at this year’s Consumer Electronics Show in Las Vegas, and whilst the new resolution has its detractors, it certainly doesn’t have its downsides in the same way 3D TVs did. At the moment the only drawback to the technology is the cost of the sets, and these will only get cheaper as the standard is more widely adopted.

At the end of the day it might not be the raw resolution of 4K that tempts you into your next TV purchase, but the inclusion of other cool technologies like High-Dynamic Range, Quantum Dot and OLED panels. Before we get into the specifics of each technology, here’s a video outlining 4K in a nutshell.
