Dell UltraSharp U4021QW 40" 60Hz 5ms WUHD Curved Monitor

All-in-One Productivity Hub with Thunderbolt 3 and RJ-45 Connectivity

Give your visuals power
More screen to captivate you: Stay on task with immersive productivity on the world’s first 40-inch curved ultrawide WUHD 5K2K monitor. With 35% more onscreen space than a 32-inch 4K 16:9 screen, you have room to view all of your work at once.

A view that draws you in: The 2500R curved screen creates a wider field of view, minimizes reflection and offers near uniform visual focus, for a comfortable, panoramic, wrap-around view.

Unmatched clarity: Across that additional screen space, you’ll see fine, intricate details with ultra high 5120 x 2160 resolution and a 140 ppi pixel density.

Consistent, vibrant colors: Expect consistent color and picture quality across a wide viewing angle, with IPS technology. See true-to-life color with an incredible color depth of 1.07 billion colors and wide color coverage across industry standards, including 100% sRGB, 100% Rec. 709 and 98% DCI-P3. DCI-P3 (which offers nearly 25% more coverage than sRGB), enables a wider range of colors and is quickly becoming the color standard for creating and viewing content.

All-encompassing sound: Integrated dual 9W speakers deliver quality sound for an auditory experience that pulls you in even further.

Your productivity hub
Connect to productivity: With Thunderbolt™ 3 and RJ45, this monitor serves as a productivity hub that delivers stable Ethernet and up to 90W of power delivery—all in a clutter-free setup.

Lightning speed: Thunderbolt™ 3 delivers speeds of up to 40Gbps, creating one compact port that does it all—delivering the fastest and most versatile connection to any dock, display or data peripheral.

Extensive connectivity: Easily connect to a variety of devices with extensive connectivity options, including Thunderbolt™ 3, DP1.4, HDMI and super speed USB 10Gbps. Plus, quick-access USB-C® and super speed USB 10Gbps ports conveniently located at the front, enable fast connection to peripherals, such as storage devices and mobile phones, with up to 15W charging capability (via USB-C).

Enhanced manageability: MAC Address pass-through, PXE Boot, and Wake-on-LAN are conveniently built in.

Multitask efficiently: Effortlessly connect two PC sources to your monitor. Our intelligent Auto KVM feature detects the second connected PC and seamlessly switches controls over. View content from both PC sources with Picture-by-Picture (PbP) and Picture-in-Picture (PiP), and use KVM (keyboard, video and mouse) to control both PCs with a single keyboard and mouse.

Masterful design
Easy on the eyes: Experience vibrant color that's easy on your eyes with ComfortView Plus, an always-on, built-in low blue light screen that reduces harmful blue light emissions while delivering excellent color performance.

Beauty meets function: Crafted with a premium, platinum silver finish, this stylish monitor features a compact base and a hidden cable management design that runs the cables through the monitor riser for a clutter-free setup. Plus, you can navigate the menu and adjust screen settings with the easy-to-use joystick control.

Comfort is key: Tilt, swivel and adjust the height of your monitor because you should be comfortable however and wherever you work.

Seamless transitions: The auto-restore feature remembers where you left off, so applications will go back to where you left them, even after you’ve unplugged.

More ways to manage: Asset management reports allow IT managers to quickly capture and track monitor information as well as configure multiple monitors at once through a single setup.

The key to convenience: Shortcut keys can save you even more time, letting you easily configure your display management settings so you can get to work faster.
