What is QHD?
Quad-HD, also commonly referred to QHD, refers to a resolution standard seen widely on computer monitors , laptops, and some mobile devices. With a screen resolution of 2560×1440 pixels, quad-HD is quadruple the resolution of standard 720p high definition, which itself has a resolution of 1280×720 pixels. QHD resolution is greater than 1080p high definition (1920×1080 resolution), though not as great as 4K or Ultra High Definition (3840×2160).
QHD is not to be mistaken for the acronym qHD, which refers to quarter high definition – a resolution standard for many smaller mobile devices. This resolution standard gets its name because at 960 pixels in width and 540 pixels in height (for a 16×9 aspect ratio), qHD is exactly one-quarter the resolution of standard high definition or 1080p. When reviewing a device’s specs and features, you can typically tell the difference as the wording quarter or quad-HD will be used to describe the product.
