3440×1440

3440×1440 is a display resolution widely used in ultrawide computer monitors. With a width of 3440 pixels and a height of 1440 pixels, it yields about 4.95 million total pixels. The aspect ratio is approximately 43:18, which is often marketed as UltraWide or 21:9-class in consumer products, and commonly referred to in shorthand as UW-QHD or UWQHD+. The resolution provides a broader horizontal workspace than standard widescreen formats, enabling more room for multitasking and immersive gaming.

Historically, 3440×1440 emerged with the rise of ultrawide monitors in the mid-2010s and has since become a standard option on 34-inch-class displays. It is particularly popular for productivity tasks such as coding, design, and data analysis, where multiple windows can be displayed side by side without stacking. In gaming and media, the wide field of view can enhance immersion, though some video content is created for 16:9 and may be letterboxed on ultrawide screens.

Technical considerations include compatibility and performance. Modern operating systems and GPUs generally support 3440×1440 with scaling options to suit different screen sizes and viewing preferences. Game and application performance depends on the graphics hardware, as rendering at this resolution requires more processing power than standard 16:9 displays. Many 3440×1440 monitors offer a range of refresh rates, commonly 60 Hz to 144 Hz, and may include features such as curved panels or HDR for enhanced visual quality.

Markets and availability: the resolution is produced by numerous manufacturers, with popular models found in professional and enthusiast segments.
