QHD display

QHD (Quad High Definition), also known as WQHD (Wide Quad High Definition) or 1440p, is a standard indicating that a display has a resolution of 2560 x 1440 pixels, with a 16:9 aspect ratio.

The "quad" part of the name is used because QHD has four times as many pixels as HD, which is 1280 x 720 or 720p. There is also an ultrawide version of QHD, known as UWQHD (Ultra Wide Quad High Definition), that is 3440 x 1440 pixels with a 21:9 aspect ratio.

The first QHD LCD was announced in the fall of 2006 by Chi Mei Optoelectronics. QHD displays are commonly found on computer monitors and mobile devices, such as smartphones and tablets.
