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.
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.
In the (2880)x480i case, the number of pixels on each line, and thus the number of times that they are repeated, is variable, and is sent to the DTV monitor by the source device. Increased Hactive expressions include “2x” and “4x” indicate two and four times the reference resolution, respectively.
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"). Requires 12 MB of memory/bandwidth for a single frame. 2560×1600 (4,096k) 2560 1600 4,096,000 16:10 24 bpp UW4K Ultra-Wide 4K
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 ...
The test chart shows the full 256 levels of the red, green, and blue (RGB) primary colors and cyan, magenta, and yellow complementary colors, along with a full 256-level grayscale. Gradients of RGB intermediate colors (orange, lime green, sea green, sky blue, violet, and fuchsia), and a full hue spectrum are also present.
This is the resolution of the UHDTV1 format defined in SMPTE ST 2036–1, [15] as well as the 4K UHDTV format defined by ITU-R in Rec. 2020, [16] and is also the minimum resolution for CEA's definition of Ultra HD displays and projectors. [21]
Apple's manufacture history of CRT displays began in 1980, starting with the Monitor /// that was introduced alongside and matched the Apple III business computer. It was a 12″ monochrome (green) screen that could display 80×24 text characters and any type of graphics, however it suffered from a very slow phosphor refresh that resulted in a "ghosting" video effect.
