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 2560x1440 pixels, quad-HD is quadruple the resolution of standard 720p high definition, which itself has a resolution of 1280x720 pixels. QHD resolution is greater than 1080p high definition (1920x1080 resolution), though not as great as 4K or Ultra High Definition (3840x2160).
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 16x9 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.

A number of common and popular devices come equipped with screens that support quad-HD resolution. This includes computer monitors, laptops, tablets, and some smartphones. To determine if a device has a QHD screen, look for information relating to the device's screen resolution. A quad-HD screen has a picture size of 2560x1440 pixels.
