Dell UltraSharp U3821DW Curved UW-QHD LED LCD Monitor - 38"

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. 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. Expect consistent colour and picture quality across a wide viewing angle, thanks to IPS technology. See true-to-life colour with an incredible colour depth of 1.07 billion colours and wide colour 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 colours and is quickly becoming the colour standard for creating and viewing content. The monitor is factory calibrated for accurate colours right from the start. Integrated dual 9W speakers deliver quality sound for an auditory experience that pulls you in even further.

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. 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 5Gbpsi 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). MAC Address pass-through, PXE Boot, and Wake-on-LAN are conveniently built in.

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.

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. Tilt, swivel and adjust the height of your monitor because you should be comfortable however and wherever you work. Optimize eye comfort with a flicker-free screen and ComfortView, a feature that reduces harmful blue light emissions.

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. The auto-restore feature remembers where you left off, so applications will go back to where you left them, even after you’ve unplugged. 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. Shortcut keys can save you even more time, letting you easily configure your display management settings so you can get to work faster.

With support for multiple operating systems, Dell Display Manager helps you stay productive however you work.

This monitor meets the latest regulatory and environmental standards such as EnergyStar® and TCO Certified, and is EPEAT® Gold registered. 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. Save energy when your monitor is not in use with PowerNap, a feature that dims or puts your monitor to sleep when it’s not in use. Dell Technologies is committed to reducing environmental impact throughout the product lifecycle.
