QHD (quad high definition)

Contributor(s): Matthew Haughn

QHD (Quad High Definition) is a resolution standard for high-end monitors, televisions and mobile devices. 

QHD is specified as 2560x1440 pixels at a16x9 aspect ratio, four times that of 720p standard high definition. Ultra wide QHD boosts the horizontal pixels to 3440 for a 21x9 aspect ratio.

QHD is a resolution suitable to large-size screens. On mobile devices, given the 5.5 inch screens, QHD makes for a very high pixel density of 538dpi. QHD is on the horizon for higher end smartphones.

A similarly named but different standard, qHD (quarter HD) is a resolution that is one-quarter of 1080p's 1980x1080.

2560x1440 is four times 360p not 720p and 1080p is 1920x1080, don't make article defining a word if you don't know the definition yourself

by four times, he meant a QHD can fit in 4, 720p sized image.. that is in a 2x2 matrix.. Hence 2560x1440 resolution in total..

1280x720 = 921,600 pixels
2560x1440 = 3,686,400 pixels

3,686,400 is four times 921,600, therefore 1440p is four times the resolution of 720p

Are Windows 7 drivers for QHD available somewhere?
