Clarity, the UK Hi Fi trade association, held their annual trade event at Dolby Soho Square, with a packed set of presentations including a brief introduction to Dolby Vision (HDR), an upcoming video standard delivering higher contrast, 4,000:1 and said to be a greater performance gain visually than current 4k is over 720p. There is a higher contrast high def format already, HDR 10, which ideally is a tasty 10-bit resolution at up to 1,000 nits. Dolby Vision will do up to 4k nits (and it really is really bright with a good laser projector!) at a 12 bit dynamic range. In addition, like the Atmos sound standard optimising the playback sound channels, this video format adapts and scales the incoming data to best match the video playback you are using. Seen at 2016 CES several manufacturers have adopted it including Vizio and LG.
