## Long description

BenQ PD3420Q is a 21:9 Ultrawide QHD monitor offering 33% extra screen workspace and VESA DisplayHDR 400 support for improved contrast, color, and detail. Equipped with BenQ AQCOLOR technology and industry-standard color performance, the monitor is factory-calibrated and Calman Verified and Pantone Validated to deliver accurate, consistent colors across workflows.

Advantages
PD3420Q provides a wider workspace for multitasking and content creation, plus HDR preview capability for video editing. AQCOLOR ensures realistic color reproduction with coverage of 100% sRGB/Rec.709 and 98% DCI-P3/Display P3 and Delta E ≤ 3. Factory calibration and ICCsync support maintain consistent color across multiple monitors and systems. Practical features include one-cable USB-C connectivity with power delivery, Picture-in-Picture and Picture-by-Picture modes, one-key shortcuts via the Hotkey Puck G2, and the ability to control two systems with a single keyboard and mouse.

Use the Hotkey Puck G2 to switch input modes, access industry-standard color presets and adjust display settings quickly. Enable PIP or PBP to work with content from two sources simultaneously and use the one keyboard/one mouse feature to control both systems. Select professional modes (Darkroom, M-book, Animation, CAD/CAM) to match the display behavior to your task, and enable ICCsync via Display Pilot software or the monitor menu to ensure matching color profiles across devices.
Recommendations
For color-critical work, perform and verify workspace calibration after setup and enable ICCsync to match color profiles between your monitor and source devices. Use M-book mode for Mac color reproduction and Darkroom mode for low-light editing to preserve detail. Keep display drivers and Display Pilot software up to date for best performance.
