1440p resolution, also known as QHD (Quad HD) or WQHD (Wide Quad HD), refers to a display resolution of 2560 × 1440 pixels. This means the screen has 2560 pixels horizontally and 1440 pixels vertically, totaling about 3.7 million pixels

. The "p" in 1440p stands for progressive scan, which means the image is drawn sequentially from top to bottom, providing smoother motion and better image quality compared to interlaced scanning

. 1440p offers significantly more detail than 1080p (1920 × 1080 pixels), with about 2.25 times more pixels, and four times the pixels of 720p (1280 × 720 pixels). It sits between 1080p and 4K (3840 × 2160 pixels) resolutions, making it a popular choice for gaming, smartphones, and computer monitors that balance visual fidelity and performance

. Additionally, there are ultrawide 1440p variants with wider aspect ratios (such as 3440 × 1440 pixels) that provide a broader field of view, especially useful for immersive gaming and productivity

. In summary, 1440p resolution means a display resolution of 2560 by 1440 pixels, offering a sharp and detailed image quality that is a step above Full HD (1080p) but below 4K UHD
