Compact Size. Enduring Build

Sleek, durable design engineered for on-the-go mobility.

The Most Powerful DUO

Peak performance meets the longest battery life ever in a dual-screen

Immersive Dual Screens

Enjoy the most expansive screen on ASUS Zenbook DUO. Work, game and create on the most seamless dual monitor set up.

The essence of a dual-display workspace, elegantly integrated into one device.

Two Screens, One Device<br>Dual-screen familiarity, but fully integrated. Enjoy your extended desktop experience now ultra-portable, more durable, and completely immersive.

Smaller, but mightier.

Smaller, Yet More Immersive<br>The ASUS Zenbook DUO is now 5% smaller yet retains its 1.65 kg*1 weight, featuring a faster processor and enhanced features. A redesigned hideaway hinge brings the dual displays closer for a seamless, step-less viewing experience anywhere, and now lays entirely flat for easy sharing.

Built to last. Designed to DUO.

Durability<br>We didn’t just build a tough device; we built one for life on the move. Featuring a full CeraluminumTM chassis, a next-gen hideaway hinge, a reinforced keyboard and everything in between, this machine is the perfect balance of unyielding strength and effortless portability.

Hideaway Hinge Reliability

Tested for over 40,000 open-close cycles, this hideaway hinge is built to last. It easily handles a 15 kg load-bearing weight, guaranteeing consistent, rock-solid support and smooth operation for years.

Pogo Pin Endurance

Our magnetic pogo pins undergo rigorous testing: 1 million retracting cycles and 20,000 side-pressure cycles for perfect stability and alignment. When retracted, they offer a sleek, uninterrupted aesthetic, ensuring a premium, secure, and seamless user experience.

Kickstand Longevity

Designed for countless adjustments. The integrated kickstand endured over 40,000 open-close cycles while supporting a 15 kg load. The angle remains firm and stable, resisting looseness over time.

Modern alchemy

CeraluminumTM is a breakthrough material that combines lightweight durability with exceptional strength. Its unmatched scratch resistance and rich, enduring texture ensure it’s built for the long haul, embodying both sustainability and resilience. Experience the Zen-like lightness, smooth texture, and unique, warm tone — inviting you to embark on a journey that stands the test of time.

Inspired by nature

Moher Gray captures the majestic, deep tones of Ireland’s iconic cliffside landscape, evoking a sense of powerful, boundless beauty.

Wear and scratch resistance

CeraluminumTM can withstand repeated friction*4 or abrasion without showing signs of damage.

Shock resistance

When your laptop accidentally knocked off a table or slipped from your hands, CeraluminumTM provides peace of mind to users about its durability.*5

Easy to clean

The material can handle everyday spills and stains without getting permanently marked.*6

The most powerful DUO

Performance

Experience a new era of efficiency, up to 40% more efficient at lower power. Power through demanding workloads, multitask effortlessly, and unlock next-generation, on-device AI features for smarter, faster, all-day productivity on your laptop.

Maxed out performance

Thermal Design<br>Engineered for max thermal headroom. To consistently deliver up to 45W TDP performance, we’ve enhanced the DUO thermal design. By increasing the intake vent size and utilizing a set of large-diameter, 97-blade fans, we achieved a 24% increase in air exhaust capacity, giving you maximum sustained performance without throttling.

Dual-battery system

Battery<br>Unleash true mobility with the DUO’s revolutionary 99 Wh dual battery design. Strategically positioned for perfect balance, it delivers an uncompromising, all-day power experience.

Ease of use

Intuitive Design<br>The laptop’s precision design enhances ease of use, featuring a spacious, smudge-resistant keyboard with excellent key travel and tactile feedback. Its enlarged touchpad supports smart gestures for smooth, intuitive navigation.

All the ports you need

ASUS Zenbook DUO packs all the connections you need. The two ultrafast Thunderbolt 4 USB-C ports support fast charging, two 4K 60 Hz or one 8K 60 Hz external displays, and up to 40 Gbps data transfers.

Effortless connection. Perfect alignment

Effortless DUO setup: an intelligent magnet array and retractable pogo pins perform automatic position correction, aligning the detachable keyboard to the lower OLED and seating the connection for immediate, uninterrupted use and charging.

Enlarged touchpad

The ErgoSense touchpad supports multitouch gestures in Windows and ASUS Smart Gestures, so you can use one, three- or four-finger shortcuts to launch frequently-used applications or instant media and system controls.

Master your multi-screen flow

Smart Versatility<br>The DUO versatile dual-screen design gives you a desktop-sized workspace on the go. Switch effortlessly between unique modes that match your workflow, using delightful software features that make two screens feel intuitive, not clunky.

Sharing mode

When the screens pass 175° and are laid flat, a quick-share menu appears automatically. Select your presentation mode to preview the flipped top display on the presenter-facing screen, then annotate and present seamlessly across both displays using the built-in digital pen or laser pointer.

Easily expand to full-screen

Swipe outward with five fingers to maximize the current window to fill both screens.

Assign windows to your preferred screen

Drag an app onto the App Switcher icon to launch the app, then choose its default screen.
