1440p is also called QHD (quad high definition) or WQHD (wide quad high definition) and is a display resolution that measures 2560 x 1440 pixels. This resolution is also commonly referred to as 2K.
Resolution explains how many pixels a display has in width x height format. The more pixels a display has, the sharper its image quality should be. QHD resolution gets its name for offering four times the definition of standard HD, aka 720p (1280 x 720 resolution).
What About WQHD?
You may also see QHD resolution referred to as UWQHD, which stands for wide quad high definition. These two acronyms represent the same resolution; WQHD is a marketing technique to emphasize the wide-screen format of the resolution.
However, vendors will also label ultra-wide monitors as UWQHD even though they don't have 2560 horizontal pixels. This is because they still have 1440 vertical pixels but have more horizontal pixels for a wider aspect ratio than 2560 x 1440's 16:9 aspect ratio. An example would be the 3440 x 1440 resolution in the Corsair Xeneon Flex 45WQHD240.
