The ASUS Zenbook Duo UX840 is a dual-screen laptop with two 14-inch 3K OLED 120Hz touch displays stacked vertically. It reimagines the laptop form factor for creative professionals, developers, and power users who benefit from a secondary screen for reference material, tools, communication, or extended desktop space — all in a single portable device.
Key Features & Benefits
- Dual 3K OLED Touch Screens: Both displays are 2880×1800 OLED with 120Hz — the secondary screen functions as a full-resolution touch workspace, not just a control panel.
- Intel Core Ultra 9 285H: Top-tier H-series processor for demanding workloads including 3D rendering, video production, and multi-application creative environments.
- 32GB DDR5 RAM: Handles virtual machines, complex After Effects timelines, and large Lightroom catalogues without slowdown.
- 2TB NVMe SSD: Stores large creative project archives locally — important for video professionals working with RAW footage.
- 120Hz OLED Refresh Rate: Smooth touch interaction and reduced motion blur when scrolling across both displays.
