Dell Pro P3426WEB 34in WQHD 100Hz Curved IPS Conferencing Monitor
Create an expansive conferencing workspace with a 34.1-inch curved IPS display, 100Hz refresh rate, integrated 4MP webcam, microphone, speakers and a versatile 90W USB-C hub.

An ultrawide workspace for collaboration
The 34.1-inch, 21:9 curved display provides additional horizontal room for documents, spreadsheets, dashboards and communication tools. Its 3440 x 1440 WQHD resolution helps keep more information visible across one screen.
A 3800R curvature brings the edges of the ultrawide display into a comfortable viewing position, while IPS technology supports consistent image quality across wide 178-degree viewing angles.
Integrated video conferencing
The built-in 4MP webcam, microphone and two 5W speakers provide an integrated setup for online meetings and hybrid work. Windows Hello compatibility supports convenient facial authentication on compatible systems.
Smooth 100Hz viewing
A refresh rate of up to 100Hz helps deliver smoother scrolling, window movement and on-screen transitions than a conventional 60Hz business monitor.
One-cable USB-C workspace
Connect a compatible laptop through USB-C to transmit WQHD video, USB data and up to 90W of power through one cable, helping reduce the number of connections required at the desk.
Integrated hub and KVM
The built-in USB hub, KVM switch and Gigabit Ethernet connection provide a central connection point for compatible computers, peripherals and wired networking.
Detailed IPS colour
The IPS panel supports 1.07 billion colours, 99% sRGB coverage, a brightness level of 350cd/m² and a 1500:1 native contrast ratio. These specifications support clear business content, presentations, websites and general creative work.
Flexible connectivity
Connect USB-C, DisplayPort and HDMI systems while keeping commonly used USB peripherals and wired networking available through the monitor.

Picture-by-Picture and Picture-in-Picture features allow supported connected sources to share the expansive display. The integrated KVM switch can also help users operate compatible connected systems with the same keyboard and mouse.

Anti-glare screen treatment, low-blue-light technology, flicker-free operation and eye-comfort features help support extended viewing during the working day.
The included stand supports height, tilt, swivel and slant adjustments. A standard 100 x 100mm VESA interface also allows the monitor to be used with compatible mounting solutions.
