The Dell UltraSharp U3423WE is a 34-inch curved monitor with a 21:9 aspect ratio, designed for multitasking and productivity. Its IPS Black panel technology delivers a high contrast ratio, producing deep blacks alongside vibrant colours for a clear visual experience. The screen’s native WQHD resolution offers sharp text and detailed imagery, while the 60 Hz refresh rate and 5 ms response time provide smooth performance for typical office applications and video playback.
Colour accuracy is a central feature, supported by a 10-bit panel that displays 1.07 billion colours and covers 98% of the DCI-P3 colour space. The gentle curve of the screen, combined with wide 178-degree viewing angles and an anti-glare surface, creates a consistent and comfortable viewing area. To reduce eye strain during extended use, the monitor incorporates both flicker-free technology and a hardware-based low blue light solution.
This monitor functions as a comprehensive productivity hub to declutter the workspace. Its integrated USB-C port provides up to 90W of power delivery, handling video, data, and charging for a compatible laptop over a single cable. A built-in KVM switch allows for seamless control of two different computers using one keyboard and mouse. The fully adjustable stand offers extensive height, swivel, and tilt ergonomics, and the monitor is also compatible with VESA mounting systems for alternative setups.
