If you can't tell your UHD from your 4K (hint – they're the same), then help is at hand in the form of the UHD Alliance. This body comprises TV makers, film production companies and broadcasting firms, and aims to make 4K's introduction to consumers go as smoothly as possible.

4K is a new resolution that contains four times as many pixels as high definition, making for a much sharper image. Confusingly, it's also known as UHD (Ultra High Definition), though hopefully the UHD Alliance will decide on one definitive name.

Expect a similar badge to the 'HD Ready' one that was found on HD TVs in the early days of high definition.

Companies involved include: DIRECTV, Dolby, LG, Netflix, Panasonic, Samsung, Sharp, Sony, Technicolor, Walt Disney Studios, Twentieth Century Fox and Warner Bros.

4K is starting to take off now that the TVs are becoming more affordable, but it still has a long way to go. Netflix has started streaming in 4K, as has Amazon Prime Instant Video, and Roku via its smart TV platform, but not many people have the right equipment to see the full benefit.
