4K TV – The Future of Video Tech?
Recently (since about halfway through last year) the tech world has been abuzz with talks of the new revolution in television: the new 4K and Ultra HD TVs, however, the mainstream media has remained fairly quiet on the subject. Which leads us to ask the question what exactly are they? And why should I scrap my 3D, HD TV and rush out to buy one?
- Well for a start Ultra HD and 4K are the same thing. They both have a screen resolution of 3840 x 2160 as opposed to full HD which has a resolution of 1920 x 1080.
- However, the different ways of measuring pixel sizes has caused some confusion about what these new televisions are called; Full HD, commonly known as 1080i and/or 1080p, refers to the number of horizontal pixels, but 4K refers to the (rounded up) number of vertical pixels, presumably because 4K sounded a little better than 2160p.
- Full HD TVs currently have 2.1 million pixels, whereas Ultra HD/4K offer around 8.3 million pixels. So if you do your pixel-maths right, you can see that 4K has basically four times as many pixels as current, Full HD TVs.
- One of the knock-on-effects of all these extra pixels appears to be on the average size of the TVs (which seems a bit like cheating). They are much larger. Much, much larger. Sony’s entry level 4K TV comes in at a rather beastly 55 inches.
- So although it is being suggested that this is the future of TV, at the moment this tech is still very much a premium, first generation product, with the cheapest one we’ve found priced at £2,500.
So whilst they may be the ‘future’ of home entertainment, it’s currently as practical and affordable to the average person as suggesting rocket ships for the morning commute…
