Product Description
The ASUS Zenbook Duo UX8407AA-SN999W is a revolutionary dual-screen Copilot+ PC laptop designed to deliver multi-monitor productivity and versatile performance in a compact, travel-friendly design. Wrapped in an elegant Moher Gray magnesium-aluminum Ceraluminum™ chassis weighing 1.65 kg and measuring under 2.34 cm thick, this laptop seamlessly folds two full-sized screens into one ultra-portable body. Built for durability on the move, its chassis meets rigorous US MIL-STD 810H military-grade standard testing.
At the center of its performance architecture is the Intel® Core™ Ultra X7 Processor 358H, featuring 16 cores, 16 threads, 18MB cache, and clock speeds up to 4.80 GHz. Equipped with an integrated Intel® Neural Processing Unit (NPU) capable of up to 50 TOPS of dedicated AI performance, the laptop accelerates Windows 11 Copilot+ AI workloads—such as live translation, video effects, and smart workflow processing—directly on-device. Graphics execution is handled by integrated Intel® Arc™ Graphics. Supported by 32GB of high-speed onboard LPDDR5X RAM and a 1TB M.2 PCIe 4.0 NVMe SSD, the machine handles complex multitasking, 4K rendering, and multi-app workflows without slowing down.
The signature highlight of the Zenbook Duo is its dual 14.0-inch 3K ($2880 \times 1800$) Lumina OLED touch displays with a smooth 144Hz refresh rate. Both displays offer VESA DisplayHDR True Black 1000 certification, up to 1000 nits peak HDR brightness, 100% DCI-P3 color gamut coverage, a 1,000,000:1 contrast ratio, PANTONE validation, and active stylus support (ASUS Pen 3.0 included). The detachable Bluetooth keyboard fits magnetically over the bottom screen for traditional laptop typing or can be removed to utilize both 14-inch displays in dual-screen or desktop mode.
Additional features include an FHD IR webcam supporting Windows Hello facial recognition, high-speed Wi-Fi 7 wireless connectivity, two Thunderbolt™ 4 ports (40Gbps), HDMI 2.1, and an airline-ready 99WHrs battery supported by 100W Type-C fast charging.
