The Dell UltraSharp U4025QW monitor features a 40-inch IPS panel with a 5120 x 2160 WUHD resolution. This 21:9 aspect ratio display provides an expansive workspace, with a high pixel density of 140 ppi for sharp text and fine details. It operates with a 120 Hz refresh rate for smooth on-screen motion and has a response time of 5 ms in fast mode. The panel delivers a typical brightness of 450 cd/m² and a 2000:1 contrast ratio, contributing to clear and distinct visuals for professional applications.
Designed for colour-critical work, the monitor's IPS Black panel technology supports 1.07 billion colours, covering 99% of the DCI-P3 and 100% of the sRGB colour spaces. The curved screen has an anti-glare surface to minimize reflections, creating a more focused viewing experience across its wide 178-degree horizontal and vertical angles. Support for VESA DisplayHDR600 allows for a greater dynamic range, rendering brighter highlights and deeper blacks in compatible content, which is useful for media editing and viewing.
This monitor functions as a comprehensive productivity hub, centered around its Thunderbolt 4 connectivity that provides up to 140W of power delivery to a connected laptop. The port selection includes one HDMI 2.1, one DisplayPort 1.4, a USB 3.2 Gen 2 hub with four downstream ports, and a headphone output. It also includes dual 9W integrated speakers for basic audio needs. The stand offers extensive ergonomic adjustments, including up to 150 mm of height, tilt, and swivel. For alternative mounting, the display is compatible with 100 x 100 mm VESA mounts.
