Productivity never looked so good

Immersive productivity: See more and achieve more on this 34” ultrawide WQHD (3440 x 1440) curved screen. With wider onscreen space, you can multitask effectively—without the need for a dual monitor setup.

All-encompassing experience: The 1900R screen curvature creates a wider field of view, minimizes reflection and offers near uniform visual focus, for a more comfortable visual experience over extended viewing periods. Plus, the built-in, dual 5W speakers deliver great sound.

Unparalleled focus: Get incredible depth, breadth and a wrap-around view that helps you focus on your work. With IPS technology, you can expect consistent colour and picture quality across a wide 178° viewing angle.

Enhanced colour coverage

Consistent vibrant colours: See stunning images in true-to-life colour with an incredible colour depth of 1.07 billion colours, and wide colour coverage of industry standards including 99% sRGB, 99% Rec. 709 and 95% DCI-P3 colour coverage. With 95% coverage of the DCI-P3 colour space (which typically offers nearly 25% more coverage than sRGB), DCI-P3 is quickly becoming the colour standard for creating and viewing content.

Accurate colour, out of the box: Your monitor is factory calibrated at 99% sRGB to an accuracy of Delta-E less than 2 for accurate colours right from the start.

Your productivity hub

Connect to productivity: With options including 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 extensive connectivity options, including DP1.4, HDMI, USB-C and super speed USB 5Gbps. Plus, quick access ports conveniently located at the front enable fast connection to peripherals and charging of mobile phones (up to 15W power charging 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 latest 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 the KVM (keyboard, video and mouse) feature control both PCs with a single keyboard and mouse.

Masterful redesign

Designed with you in mind: Navigate the menu and adjust screen settings with the easy-to-use joystick control. Plus, the three-sided, ultra thin borders let you dive in without distraction.

Beauty meets function: Crafted with a premium, platinum silver finish, this sleek monitor features a compact base and a hidden cable management design that runs the cables through the monitor riser.

Comfort is key: Tilt, swivel and adjust the height of your monitor to a maximum of 150mm because you should be comfortable while you work.

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

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.
