1440p is a family of video display resolutions that have a vertical resolution of 1440 pixels. The p stands for progressive scan, i.e. non-interlaced. The 1440 pixel vertical resolution is double the vertical resolution of 720p, and one-third (about 33.3%) more than 1080p. QHD (Quad HD) or WQHD (Wide Quad HD) is the designation for a commonly used display resolution of 2560 × 1440 pixels in a 16:9 aspect ratio. As a graphics display resolution between 1080p and 4K, Quad HD is regularly used in smartphone displays, and for computer and console gaming.

Support

1440p video mastered from 4:3 ratio content can be displayed with 1920×1440 or higher resolution such as QXGA or 2304×1440 with scaling, windowboxing, or pillarboxing. Widescreen 16:9 aspect ratio 1440p requires 2560×1440 (WQHD) resolution, possible with WQXGA, 2560×1920, or higher resolution with letterboxing, scaling, or windowboxing. The HDMI 1.3 specification supports WQXGA, and hence widescreen 1440p.

Usage

Early uses of QHD computer displays became commonly available in 2010. Dell's UltraSharp U2711 monitor was released in 2010 as WQHD, with a 1440p widescreen. [1] The 27-inch Apple LED Cinema Display released in 2010 also had a native resolution of 2560 × 1440, as did the Apple Thunderbolt Display which was sold from July 2011 to June 2016.

By 2020 QHD had expanded to a common resolution for computer gaming, with multiple video cards available that supported high frame rates at that resolution. [2] [3] In early 2021, QHD gaming laptops with fast refresh rates were introduced by multiple computer manufacturers. [4]

According to Steam's February 2024 Hardware & Software Survey, the resolution 2560 x 1440 has increased in overall usage on Steam by ~3% from January 2024, totaling to ~19% of its total userbase. [5]

In relation to smartphones, 1440p displays are sometimes marketed as "Quad HD", as it is four times the resolution of 720p high definition. The Vivo Xplay 3S, released December 2013, was the first smartphone to use a 1440p display; by 2015, 1440p had seen wider adoption by high-end flagship smartphones from major companies. [6] [7] [8]

In September 2020, Microsoft revealed the Xbox Series S would support a resolution of 1440p at 120 FPS. [9]

Application of "2K" to 2560 × 1440

"2K" is sometimes applied to 2560 × 1440 (commonly known was 1440p). This is inconsistent with "4K" denoting approximately 4,000 horizontal pixels, which makes 1920 or 2048 pixels wide the closet to "2K", a label which predates the use of 2560 × 1440. [10] [11] Some sources prefer "2.5K" as a term for 2560 × 1440 [12] to avoid this confusion, and there is a similar "2.7K" (2720 × 1530) used by some drones, [13] as well as a "2.8K" (2880 × 1620). [14] [15]

<span class="mw-page-title-main">Display resolution</span> Number of distinct pixels in each dimension that can be displayed

The display resolution or display modes of a digital television, computer monitor or display device is the number of distinct pixels in each dimension that can be displayed. It can be an ambiguous term especially as the displayed resolution is controlled by different factors in cathode ray tube (CRT) displays, flat-panel displays and projection displays using fixed picture-element (pixel) arrays.

High-definition video is video of higher resolution and quality than standard-definition. While there is no standardized meaning for high-definition, generally any video image with considerably more than 480 vertical scan lines or 576 vertical lines (Europe) is considered high-definition. 480 scan lines is generally the minimum even though the majority of systems greatly exceed that. Images of standard resolution captured at rates faster than normal, by a high-speed camera may be considered high-definition in some contexts. Some television series shot on high-definition video are made to look as if they have been shot on film, a technique which is often known as filmizing.

<span class="mw-page-title-main">1080p</span> Video mode

1080p is a set of HDTV high-definition video modes characterized by 1,920 pixels displayed across the screen horizontally and 1,080 pixels down the screen vertically; the p stands for progressive scan, i.e. non-interlaced. The term usually assumes a widescreen aspect ratio of 16:9, implying a resolution of 2.1 megapixels. It is often marketed as Full HD or FHD, to contrast 1080p with 720p resolution screens. Although 1080p is sometimes referred to as 2K resolution, other sources differentiate between 1080p and (true) 2K resolution.

<span class="mw-page-title-main">Display aspect ratio</span> Ratio between a displays width and height

The display aspect ratio (or DAR) is the aspect ratio of a display device and so the proportional relationship between the physical width and the height of the display. It is expressed as two numbers separated by a colon (x:y), where x corresponds to the width and y to the height. Common aspect ratios for displays, past and present, include 5:4, 4:3, 16:10, and 16:9.

"21:9" is a consumer electronics (CE) marketing term to describe the ultrawide aspect ratio of 64:27, designed to show films recorded in CinemaScope and equivalent modern anamorphic formats. The main benefit of this screen aspect ratio is a constant display height when displaying other content with a lesser aspect ratio.

<span class="mw-page-title-main">4K resolution</span> Video or display resolutions with a width of around 4,000 pixels

<span class="mw-page-title-main">2K resolution</span> Display devices or content having horizontal resolution of approximately 2,000 pixels

2K resolution is a generic term for display devices or content having a horizontal resolution of approximately 2,000 pixels. In the movie projection industry, Digital Cinema Initiatives is the dominant standard for 2K output and defines a 2K format with a resolution of 2048 × 1080. For television and consumer media, 1920 × 1080 is the most common 2K resolution, but this is normally referred to as 1080p.

6K resolution refers to display formats with a horizontal resolution of around 6,000 pixels and a vertical resolution of around 3,000 pixels. But the exact number may vary depending on the aspect ratio and pixel shape. 6K resolution is higher than 4K resolution, which has about 4,000 pixels horizontally, and lower than 8K resolution, which has about 8,000 pixels horizontally.

<span class="mw-page-title-main">Graphics display resolution</span> Width and height of an electronic visual display device, such as a computer monitor, in pixels

The graphics display resolution is the width and height dimension of an electronic visual display device, measured in pixels. This information is used for electronic devices such as a computer monitor. Certain combinations of width and height are standardized and typically given a name and an initialism which is descriptive of its dimensions. A graphics display resolution can be used in tandem with the size of the graphics display to calculate pixel density. An increase in the pixel density often correlates with a decrease in the size of individual pixels on a display.
