Description for Dell U4021QW 39.7" 21:9 Curved IPS Monitor, 5120 x 2160 Resolution, 8 ms (GtG) Response Time, 60 Hz Refresh Rate | U4021QW

Stay immersed and productive with the U4021QW 39.7" 21:9 Curved IPS Monitor in silver from Dell. Featuring a 39.7" In-Plane Switching (IPS) panel, this monitor features a 5120 x 2160 resolution for plenty of screen space. Dock your laptop using an all-in-one Thunderbolt 3 connection that supports data and video, as well as 90W of power delivery or connect using DisplayPort and HDMI inputs. A USB Type-A to B data cable can be used to enable the built-in USB hub, comprised of a USB 3.2 Gen 2 Type-C port with up to 15W of power delivery and four USB 3.2 Gen 2 Type-A ports. An RJ45 port is also present, enabling wired internet connectivity.

Supporting 1.07 billion colors, 100% of the sRGB and Rec. 709 gamuts, and 98% of the DCI-P3 gamut, this monitor is designed to deliver accurate colors. A typical 8 ms (GtG) response time can be overdriven to 5 ms, while the 60 Hz refresh rate ensures smooth performance. Furthermore, a 1000:1 static contrast ratio and 300 cd/m² brightness provide sharp and clear visuals. Viewing comfort is facilitated by wide 178° horizontal and vertical viewing angles. Adjust the height, swivel, and tilt of the stand to find the perfect view or attach the monitor to a third-party mount or stand using the VESA pattern. A Kensington Lock slot is also present, allowing the monitor to be secured using a compatible lock, available separately.

More Screen to Captivate You

Stay on task with immersive productivity thanks to 39.7" 5120 x 2160 display. With 35% more onscreen space than a 32" 4K screen, you have room to view all of your work at once.

Curved for Immersion

The 2500R curved screen creates a wider field of view, minimizes reflections, and offers near uniform visual focus for a comfortable, panoramic view.

Built for Clarity

The 5120 x 2160 resolution and 140-ppi pixel density ensure plenty of on-screen detail.

Vibrant Colors

Take advantage of consistent color and picture quality across wide viewing angles with IPS screen technology. See true-to-life color with support for 1.07 billion colors and wide color coverage across industry standards, including 100% of the sRGB and Rec. 709 gamuts, and 98% of the DCI-P3 gamut.

Integrated Audio

Integrated dual 9W speakers deliver on-board sound.

Connect to Productivity

With Thunderbolt 3 and RJ45 connectivity, 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 40 Gb/s, providing one compact connection for docking, display, and data transfer.

Flexible Connectivity

Easily connect to a variety of devices with extensive connectivity options, including Thunderbolt 3, DisplayPort 1.4, HDMI, and USB interfaces. Plus, quick-access USB 3.2 Gen 2 Type-A and C ports conveniently located at the front of the monitor enable fast connection to peripherals, such as storage devices and mobile phones, with up to 15W of charging capability via USB Type-C.

Optimized Manageability

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

Efficiently Multitask

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

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 accurate colors.

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.


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

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.

    Great monitor, one of the few 5K ultra wide screens.

    Matte, so no glare.
