Dual-screen ultraportable

The ASUS Zenbook Duo UX8406CA-PS99T-HID4 is a 14 inch 3K OLED touch laptop powered by an Intel Core Ultra 9-285H processor with 16 cores and Intel Arc graphics. It ships with Windows 11 Home and 32 GB of LPDDR5X memory. An 8 TB PCIe 4.0 x4 NVMe SSD provides the primary storage.

Creative multitaskers and mobile professionals

The dual-screen form factor suits users who need extra display real estate for timelines, code, or reference material while travelling. The 120 Hz OLED panel delivers 2880 by 1800 resolution for colour-critical work. Buyers who require discrete GPU compute or user-replaceable memory should evaluate alternative platforms.

Capacity and thermal headroom

The 8 TB NVMe drive holds large project libraries, raw footage, and virtual machines with room to spare. Gelid GC Extreme thermal compound on the CPU and GPU helps sustain the 5.4 GHz max turbo frequency under load. The 32 GB soldered memory ceiling limits extreme multitasking scenarios beyond the configured capacity.

Questions about this item

Will the 14 inch 3K OLED touch display and dual-screen layout fit in a standard 14 inch laptop sleeve?

The chassis measures 12.34 by 8.58 inches and ranges from 0.57 to 0.78 inches thick, so a sleeve sized for a typical 14 inch ultrabook should accommodate it.

Can the 32 GB LPDDR5X memory be upgraded later if my workloads grow?

The memory is soldered on board and cannot be expanded after purchase.

Does the 8 TB PCIe 4.0 x4 NVMe SSD leave a second M.2 slot free for adding another drive?

The specification lists a single 8 TB M.2 PCIe 4.0 x4 NVMe SSD with no mention of an additional slot.
