The Dell UltraSharp U2421E monitor features a 24.1-inch IPS panel with a WUXGA resolution of 1920 x 1200 pixels. Its 16:10 aspect ratio provides additional vertical space for productivity tasks, operating at a 60 Hz refresh rate and an 8 ms response time. The display achieves a typical brightness of 350 cd/m² and maintains a 1000:1 contrast ratio, delivering clear and consistent visuals suitable for office environments.
This monitor is designed for color-accurate work, covering 99% of the sRGB color gamut with an 8-bit color depth. The IPS technology provides wide viewing angles of 178 degrees horizontally and vertically, while the anti-glare screen surface reduces reflections. For viewing comfort during extended use, it incorporates ComfortView Plus, a hardware-based low blue light technology, alongside a flicker-free screen to minimize eye strain.
It functions as a versatile productivity hub, offering a range of ports including one HDMI 1.4, two DisplayPort 1.4 inputs, and a USB-C port with 90W power delivery. The built-in USB 3.2 Gen 1 hub also includes two USB Type-A downstream ports and a headphone output for connecting peripherals. The stand provides comprehensive adjustability, with 150 mm of height adjustment, tilt from -5 to 21 degrees, a -45 to 45 degree swivel, and a full pivot for vertical orientation. For alternative setups, it supports a standard 100 x 100 mm VESA mount.
