QHD (quad high definition)

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.
