A 27-inch 2K monitor offers a sharp QHD (2560x1440) resolution on a medium-sized screen, ideal for detailed visuals, combining crisp text with immersive gaming/media, often featuring fast IPS panels for vibrant colors and wide viewing angles, high refresh rates (144Hz+), low response times (1ms), and adaptive sync (FreeSync/G-Sync) for smooth, tear-free action, alongside features like HDR support and eye-care tech.
