Earlier this year the first Ultra HD televisions arrived with a resolution of 3840x2160 pixels. These were massive 84-inch TVs from companies like Sony and LG, with price tags in excess of 20,000 pounds. Almost six months later Sony is the first to introduce a more affordable UHD TV. The new 55-inch 55X9005 costs £3,999. That's still a lot of money, but nevertheless more consumer-friendly than the 84-inch model.
Sony also has a 65-inch version of the X9005, for a more hefty £5,999. It will be interesting to find out what the picture quality is of the X9005 TVs, and whether there's any point in having 4K resolution on a smaller screen.
