The DCI 4K standard has twice the horizontal and vertical resolution of DCI 2K (2048 × 1080), with four times as many pixels overall. Digital movies made in 4K may be produced, scanned , or stored in a number of other resolutions depending on what storage aspect ratio is used.
The resolution 3840 × 2160, sometimes referred to as 4K UHD or 4K × 2K, has a 16:9 aspect ratio and 8,294,400 pixels. It is double the size of Full HD ( 1920 × 1080 ) in both dimensions for a total of four times as many pixels, and triple the size of HD ( 1280 × 720 ) in both dimensions for a total of nine times as many pixels.
This chart shows the most common display resolutions, with the color of each resolution type indicating the display ratio (e.g., red indicates a 4:3 ratio). This article lists computer monitor, television, digital film, and other graphics display resolutions that are in common use. Most of them use certain preferred numbers.
Also, the highest resolution supported by dual-link DVI at a standard colour depth and non-interlaced refresh rate (i.e. at least 24 bpp and 60 Hz). Used on MacBook Pro with Retina display (13.3").

In digital cinema, resolutions are represented by the horizontal pixel count, usually 2K (2048×1080 or 2.2 megapixels) or 4K (4096×2160 or 8.8 megapixels). The 2K and 4K resolutions used in digital cinema projection are often referred to as DCI 2K and DCI 4K. DCI stands for Digital Cinema Initiatives.
1080p progressive scan HDTV, which uses a 16:9 ratio. Some commentators also use display resolution to indicate a range of input formats that the display's input electronics will accept and often include formats greater than the screen's native grid size even though they have to be down-scaled to match the screen's parameters (e.g. accepting a 1920 × 1080 input on a display with a native 1366 ...
