Ultra HD, also known as 4K, is a TV screen resolution of over eight million pixels (3840 x 2160 pixels), around four times that of Full HD (1920 x 1080 pixels).
The first 4K TVs were unleashed last year, but at over 80-inches in screen size and price tags north of £20,000, they were only for the super-rich. Now Samsung has launched a 55-inch Samsung F9000 series 4K TV for £3,999.99; an almost affordable price. We took a first look at the new TV.
