Exceptional 4K detail with QD-OLED technology
The Dell UltraSharp U3226Q combines a spacious 31.5-inch screen with 3840 x 2160 4K UHD resolution, providing a detailed workspace for photography, video production, design applications, colour grading and multi-window productivity.
Quantum Dot OLED technology combines individually controlled OLED pixels with quantum-dot colour reproduction. Its 1,500,000:1 native contrast ratio helps deliver deep black levels, bright highlights and clear separation between light and dark content.
Smooth 4K performance at 120Hz
The monitor supports 3840 x 2160 resolution at up to 120Hz and a 0.03ms grey-to-grey response time. Scrolling, timeline navigation, motion and on-screen transitions appear smooth and responsive.
Wide professional colour coverage
The display covers 99% DCI-P3, 99% Display P3, 94% Adobe RGB, 100% sRGB, 100% BT.709 and 80% BT.2020 for professional creative and colour-sensitive workflows.
Built-in hardware colorimeter
An integrated colorimeter supports display calibration without requiring a separate desktop calibration device. Dell Colour Management tools also support remote calibration and monitor fleet management.
Professional HDR support
VESA DisplayHDR True Black 500 and Dolby Vision HDR support help compatible content display with deep blacks, detailed highlights and an extended tonal range.
Designed for controlled colour workflows
The anti-glare low-reflectance screen treatment helps reduce reflections while preserving the detailed image quality of the QD-OLED panel. A monitor hood and microfibre cloth are included to help support colour-critical workspaces.
The monitor supports 1.07 billion colours and reaches brightness levels of up to 1000cd/m² for compatible peak-highlight content.
