4K resolution is a generic term for display devices or content having horizontal resolution on the order of 4,000z pixels. This technology has been designed for digital cinema and computer graphics. It is named as 4K because it has approximately 4000 pixels horizontal resolution. Previous generations of video resolutions were described by the vertical resolution (e.g., 1080p refers to a signal with 1080 vertical lines). With the introduction of 4K in market, users can now receive higher image definition quality, more detailed picture, better fast-action and larger projection surface visibility.
Smart TVs and projectors are expected to bring boom in the 4K market in the next three to four years. 4K resolution products have been on the outlook for several years, but only in the recent times it got the attention of consumers particularly with fall of price spectrum of 4K products.
