Dell UltraSharp 40 Curved – Ultra-Wide Workspace & Hub Integration

Transform your workspace with the Dell UltraSharp 40 Curved Thunderbolt Hub Monitor (U4025QW). With a massive 5120 × 2160 ultra-wide resolution and a 120 Hz refresh rate, this curved 40-inch display provides the screen real estate of two side-by-side monitors — delivering seamless multitasking, immersive content creation, and next-level productivity.

Stunning Visuals & Colour Precision

Built with Dell’s “IPS Black” panel technology, the U4025QW offers deeper contrast (2000:1 typical), wide 178° viewing angles, and exceptional color accuracy. It covers 99% DCI-P3/Display P3 and 100% sRGB/BT.709 with a Delta E of less than 2 — ideal for photo and video editing, professional design work and colour-critical tasks.

Hub-Style Connectivity & Single-Cable Simplicity

Say goodbye to clutter: this monitor functions as a full Thunderbolt 4 hub. One upstream Thunderbolt 4 cable can deliver video, data, network (2.5 GbE), and up to 140 W of power delivery to your laptop — meaning you connect one cable and you’re done. Additional downstream Thunderbolt 4, USB-C, USB-A ports, HDMI 2.1 and DisplayPort 1.4 ensure full compatibility with modern devices.

Ergonomic Design & Curved Immersion

The gentle 2500R curvature of the panel helps immerse you in the widescreen experience, while the fully adjustable stand enables Height (150 mm), Tilt (-5° to +21°), Swivel (-30° to +30°) for optimal comfort during long hours. Cable management is built in to keep your desk neat.

Productivity & Comfort Features

With support for Picture-by-Picture (PBP) and Picture-in-Picture (PiP), the U4025QW enables dual-PC workflows and easy multitasking. The monitor is TÜV Rheinland five-star-rated for eye comfort, incorporating ComfortView Plus to reduce low-blue-light exposure and an ambient light sensor for auto brightness and colour-temperature adjustment.
