The name "4K resolution" refers to a horizontal resolution of approximately 4,000 pixels. The use of width to characterize the overall resolution marks a switch from previous television standards such as 480i and 1080p, which categorize media according to its vertical dimension. Using that same convention, 4K UHD would be named 2160p.
2K resolution is a generic term for display devices or content having horizontal resolution of approximately 2,000 pixels.[1] Digital Cinema Initiatives (DCI) defines 2K resolution standard as 2048×1080.
