4K resolution, also called
4K, refers to a display device or content having horizontal
resolution on the order of 4,000 pixels. Several 4K resolutions exist in the fields of
digital television and
digital cinematography. In the movie projection industry,
Digital Cinema Initiatives (DCI) is the dominant 4K standard. In television and consumer media, 4K
UHD or UHD-1 is the dominant 4K standard. By 2015, 4K television market share had increased greatly as prices fell dramatically during 2014 and 2015. By 2025, more than half of US households are anticipated to have a 4K-capable TV (
2160p), which would be much faster than the
adoption curve of FullHD (
1080p).
