2560×1440

2560×1440, also written 2560x1440 or 2560×1440, is a display resolution commonly used in computer monitors and laptops. With an aspect ratio of 16:9, it provides more pixels than standard 1920×1080 displays while remaining lower than 4K resolutions. It is widely marketed as QHD (Quad High Definition) or WQHD (Wide Quad High Definition).

Uses and context: The resolution became popular in the mid-2010s as a balance of image sharpness, performance, and price. It is commonly deployed on 27-inch and larger monitors and is favored for gaming, photo and video editing, and general productivity. Some devices and vendors refer to it as 2.5K.

Technical characteristics: The total pixel count is 3,686,400. The pixel density (PPI) depends on screen size; for a 27-inch monitor it is roughly 109 PPI, while a 32-inch display would be closer to 90 PPI. Supported refresh rates vary by panel and interface; most modern connections (DisplayPort 1.2 or HDMI 2.0 and newer) can drive 2560×1440 at 60 Hz, with some panels offering higher refresh rates (120 Hz, 144 Hz) or HDR options.

Relation to other resolutions: It sits between 1080p (1920×1080) and 4K (3840×2160) in total pixels. It is not the same as 2K cinema resolution, and not all devices display the full resolution unless the hardware and software support it. The name QHD or WQHD reflects its status as a higher-end high-definition standard.
