27inch

27inch is a common marketing term for a display with a diagonal of 27 inches. It is used to describe computer monitors, televisions, and other screens. The designation indicates size, not a fixed standard; actual dimensions depend on the aspect ratio and the design of the bezel.

Most 27-inch monitors use 16:9 as the default aspect ratio, though some are 16:10 or 21:9 ultrawide. Resolutions vary, with 2560x1440 (WQHD) and 3840x2160 (4K UHD) being common. Pixel density depends on resolution: roughly 110 PPI at 2560x1440 and about 160 PPI at 3840x2160 on a 27-inch diagonal. The physical width and height differ by aspect ratio; a 27" 16:9 panel is approximately 598 mm wide and 336 mm tall, while ultrawide variants are proportionally wider.

Panel technology and performance vary. IPS panels are favored for color accuracy and wide viewing angles, VA panels for higher contrast, and TN panels for speed at lower cost. Gaming-oriented 27-inch monitors may offer 120 to 240 Hz refresh rates and fast response times, while many models support high dynamic range (HDR) with varying degrees of effectiveness. Common video inputs include HDMI and DisplayPort, with USB-C increasingly present on higher-end or dockable models.

Use and ergonomics: the 27-inch size balances a large viewing area with desk space, suitable for productivity, graphic design, and gaming. Adjustable stands (height, tilt, swivel, pivot) and VESA mounting are common. Availability, performance options, and price vary with resolution, panel type, brightness, and adaptive-sync features.
