4K is an overarching term to describe visual resolution technology that offers more pixels than Full HD. 4K resolution is 3,840 x 2,160 and the number of pixels is four times that of Full HD, so picture quality is much better.
4K quality delivered by Now One is 4K Ultra HD (4K UHD), a much higher standard. As well as providing 3,840 x 2,160 resolution, it needs to comply with the HDMI 2.0 and HDCP 2.2 standards. HDMI 1.x only supports 4K@25/30Hz, but HDMI 2.0 supports up to 4K@ 50/60Hz, thereby improving picture quality for fast-motion video. HDCP 2.2 is a technology designed to prevent illegal copying of 4K UHD content. Now One is HDMI 2.0 and HDCP 2.2 certified.
In order to ensure you can watch all 4K content, we recommend that you choose a TV set and set-top box that support HDMI 2.0 and HDCP 2.2.
