Description

The BenQ PD3420Q is a powerhouse for creative professionals who demand precision and expansive screen real estate. This 34-inch WQHD monitor utilizes a 21:9 aspect ratio to replace dual-monitor setups, offering a seamless canvas for video timelines and complex design projects. With 98% DCI-P3 coverage and 100% sRGB, it ensures that what you see on screen translates perfectly to the final output, backed by VESA DisplayHDR 400 for enhanced contrast and depth.


This product is for:

- Video Editors: The 21:9 UltraWide format provides an extended horizontal timeline, significantly reducing the need for constant horizontal scrolling during post-production.
- Graphic Designers: Pantone Validated and Calman Verified color accuracy ensures professional-grade fidelity for both print and digital media projects.
- CAD/CAM Engineers: Specialized display modes enhance contrast in technical illustrations, making intricate lines and shapes easier to distinguish in software like Solidworks.
- Mac Users: The dedicated M-Book mode synchronizes the monitor's color profile with MacBook displays for a consistent visual experience across devices.
- Multitasking Professionals: The integrated KVM switch and Picture-in-Picture (PiP) / Picture-by-Picture (PbP) modes allow for managing two separate systems simultaneously on one screen.

Detailed specifications:

- Panel Type: 34-inch IPS with Anti-Glare coating and LED backlighting.
- Resolution: 3440 x 1440 (WQHD) at 60Hz refresh rate.
- Color Performance: 98% DCI-P3, 100% sRGB, 100% Rec.709, and Delta E ≤ 3.
- Brightness: 350 nits (typical), 400 nits (HDR peak) with HDR10 support.
- Connectivity: 1x USB-C (65W Power Delivery, DP Alt Mode), 2x HDMI 2.0, 1x DisplayPort 1.4, 3x USB 3.1 downstream.
- Ergonomics: Height adjustment (150mm), Tilt (-5° to 20°), Swivel (30°/30°), and VESA 100x100mm mounting.


Working on the PD3420Q feels like having a command center at your fingertips. The Hotkey Puck G2 allows for instant switching between color modes like Darkroom or Animation without fumbling with OSD buttons. BenQ's Uniformity Technology ensures consistent brightness and color across the entire 34-inch panel, preventing the vignetting effect common in larger screens. With 65W USB-C charging, your laptop stays powered through a single cable, keeping the workspace clean and efficient while maintaining high-speed data transfer.


Compared to the 27-inch PD2705U, the PD3420Q offers significantly more horizontal space, which is crucial for side-by-side window management. While the PD3225U offers 4K resolution, the PD3420Q’s 21:9 aspect ratio is often preferred by video editors over the standard 16:9 format for cinematic workflows. Unlike entry-level ultrawide monitors, the PD3420Q includes professional certifications like Pantone and Calman, ensuring it meets rigorous industry standards for color-critical work right out of the box.
