Many leading manufacturers are marketing televisions described as 4K, Ultra HD (UHD) or 4K Ultra HD. The screens on these TVs are designed to show pictures with up to four times the detail of regular high definition TVs (1080p) and are becoming increasingly affordable. Many Freeview Play TVs from Panasonic (and LG later in 2016) incorporate 4K technology. Not surprisingly these TVs work well with HD signals so Freeview HD looks great on a 4K TV. However there are regular 4K programmes currently broadcast on Freeview, satellite or cable networks. Some on-demand services such as Netflix, Amazon and YouTube offer a selection of videos in 4K/UHD. To get the maximum benefit from 4K TVs you need a large screen and also have to sit reasonably close to it. For most people HD is a great experience in their living rooms. TVs with 4K capability may also have a technology called high dynamic range (HDR) which will enhance existing programming. HDR will display a wider range of colours which will make your TV picture more realistic. It also improves how your TV handles contrast which makes for a brighter, more dynamic image (hence the name).
