Key Features

Wide 5K2K WUHD Workspace

The 40-inch canvas gives creative projects room to breathe, while 5K2K clarity helps reveal fine details in designs, edits and other precision-focused work. Its broad format can keep more tools, timelines and visual content in view within one focused workspace.

Nano IPS Black With HDR 600

Nano IPS Black panel technology and HDR 600 work together to produce deep blacks, vivid color and stronger contrast. That combination helps images retain visual impact across bright highlights, dark areas and richly colored content.

Up to 99% DCI-P3 Color

Coverage of up to 99% of the DCI-P3 color gamut supports wide-gamut creative work, preserving the range between bold hues and more subtle shades. It is designed for projects where color precision matters throughout the editing process.

2000:1 Contrast Ratio

A 2000:1 contrast ratio adds tonal separation and visual depth, bringing more distinction to dark imagery and layered compositions. Deeper blacks help fine details remain easier to evaluate when working with contrast-rich content.

Thunderbolt 5 With 96W Power Delivery

Thunderbolt 5 supports a fast, stable connection for 5K2K production while providing 96W charging to a compatible laptop.¹ Combining the display signal and laptop power through one connection creates a more streamlined way to dock a mobile creative workstation.

Single-Cable Daisy-Chain Setup

The daisy-chain connection can link a laptop and two monitors with a cleaner cable path, giving multi-display workflows more room without adding unnecessary desktop clutter. A second monitor is required and sold separately.²
