Dell U3821DW 37.5" 21:9 Curved IPS Monitor

Experience clarity, productivity and connectivity on this 37.5" ultrawide WQHD+ curved, hub monitor with 95% DCI-P3 color and integrated speakers.

Bring everything together

More screen to captivate you: See all of your work and multitask like you've always wanted with more onscreen space on this 37.5-inch ultrawide WQHD+ (3840 x 1600) curved screen. And with a vertical height of 1600 pixels, you can see more and scroll less.

A view that draws you in: The 2300R curved screen creates a wider field of view, minimizes reflection and offers near uniform visual focus, for a comfortable, panoramic, wrap-around view.

Consistent, vibrant colors: Expect consistent color and picture quality across a wide viewing angle, thanks to 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 95% DCI-P3. DCI-P3 (which offers nearly 25% more than coverage than sRGB), enables a wider range of colors and is quickly becoming the color standard for creating and viewing content.

Accurate color, out of the box: Your monitor is factory calibrated for accurate colors right from the start.

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 RJ45 and USB-C, your monitor serves as a productivity hub that delivers stable Ethernet and up to 90W of power delivery—all in a clutter-free setup.

Extensive connectivity: Easily connect to a variety of devices with a wide range of connectivity options, including DP1.4, HDMI and USB-C: a single-cable solution that transmits data and video while delivering up to 90W of power to charge a wide range of laptops. Plus, quick-access USB-C and super speed USB 5Gbps ports conveniently located at the front, enable fast connection to peripherals, such as storage devices and mobile phones, with a charging capability of up to 15W (via USB-C).

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

Multitask efficiently: Connect two PC sources to the 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). KVM (keyboard, video and mouse) allows you to control both PCs with a single keyboard and mouse.

Designed with you in mind

Beauty meets function: Crafted with a premium, platinum silver finish, this sleek monitor features a streamlined 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.

Easy on the eyes: Optimize eye comfort with a flicker-free screen and ComfortView, a feature that reduces harmful blue light emissions.

Green thinking: for today and tomorrow

Environmental standards: This monitor is made of 85% PCR (Post-consumer Recyclable Plastic), meets the latest environmental standards such as ENERGY STAR® and TCO, and is EPEAT Gold registered.

Eco-conscious packaging: To reduce our manufacturing impact on the environment, this monitor is shipped Styrofoam-free and the packaging is made of at least 75% recycled cardboard.

Dell Display Manager

Productive at every level: Easy Arrange allows you to easily tile multiple applications across one or more screens with 38 pre-set window partitions and the ability to personalize up to five windows, giving you improved multitasking abilities.

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.
