Dual-Screen Ultrabook for Mobile Creators

The ASUS Zenbook Duo UX8406CA-PS99T is a 14-inch 3K OLED touch laptop built around two displays. An Intel Core Ultra 9 285H processor with 16 cores and Intel Arc graphics drives creative workloads on the go. Windows 11 Home ships pre-installed on the 1 TB PCIe 4.0 x4 NVMe SSD.

32 GB LPDDR5X Memory and 1 TB NVMe Storage

Thirty-two gigabytes of soldered LPDDR5X memory gives headroom for heavy multitasking and large project files. The 1 TB PCIe 4.0 x4 NVMe SSD supplies fast boot and load times for applications and assets. Storage expansion depends on the single M.2 slot already occupied by the factory drive.

Upgraded Thermal Paste Over Standard Build

HIDevolution replaces the stock thermal interface with Gelid GC Extreme on the CPU and GPU. The upgrade targets lower sustained temperatures during long rendering or compile sessions compared with an unmodified unit. The benefit is most noticeable when the 16-core Arrow Lake chip runs near its 5.4 GHz maximum turbo frequency for extended periods.

Questions about this item

Will the 14" 3K OLED 120 Hz touch display and dual-screen layout work with my existing USB-C dock and external monitor?

The laptop provides USB-C ports with DisplayPort Alt Mode so the 2880 x 1800 120 Hz panel and the secondary screen can both drive an external display through a compatible dock.

How can I verify the Ultra 9 285H is hitting its 5.4 GHz turbo and the Arc graphics are active after setup?

Open Task Manager or Intel Arc Control to confirm 16 cores, 24 MB cache, 5.4 GHz max turbo on the CPU and the Arc GPU listed under display adapters.

What ships in the box with the UX8406CA-PS99T and what must I buy separately?

The box includes the laptop, a USB-C power adapter, and documentation; an active stylus for the touch screen is not included and must be purchased separately.
