qHD (quarter high definition)

qHD (quarter high definition) is a resolution standard for mobile devices.

qHD became common on higher end smartphones as well as the Playstation Vita in 2011. Specified as 960x540 pixels at a 16x9 aspect ratio, qHD is one-quarter full high definition or 1080p's 1920 x1080 resolution. Although qHD is a lower resolution, the size of mobile device screens makes this a relatively high pixel density of around 300dpi. 

 A separate standard, QHD (Quad HD) is quadruple the 720p standard high definition resolution of 1280 x720, at 2560x 440 pixels. Formally only seen on monitors and high end TVs, QHD is now appearing on some mobile devices.
