ASUS Zenbook DUO (UX8406) review – Dual OLED Multitasking Masterpiece for Creators

The dual-screen laptops are still a rare find but they are slowly becoming more widely available. Last year, Lenovo Yoga Book 9 (13IRU8) impressed us with its many features and transforming capabilities. Now, the ASUS Zenbook DUO (UX8406) has the upper hand with its pure performance.

This device has two OLED displays but the second panel is covering a powerful Intel Meteor Lake-H CPU. You can choose among three chips with a 28W base power while the top-end variant is the Intel Core Ultra 9 185H. Our laptop is equipped with the latter to see how good the cooling is when it has to tame a 16-core beast.

There are no IPS options which is actually a positive thing. You get two 1200p 60Hz OLED screens or if money isn’t a problem – a duo of 3K 120Hz screens. The high resolution shouldn’t be an issue for light gaming thanks to the snappy Intel Arc (7-Cores) and Intel Arc (8-Cores) iGPUs. Well, it’s not a gaming device, but let’s just appreciate the fact that our machine showed 100 FPS in CS:GO on Max details.

Interestingly, servicing the device is a hard job but it’s not impossible. Opening the Apple MacBook Pro (14-inch, M3) is easier but Apple only lets you watch the internals. ASUS has made the Zenbook DUO serviceable – the SSD and the battery can be replaced if needed.

As you may already guess, the UX8406 can be used in different modes such as dual-screen mode with or without the external keyboard, and as a normal laptop. Let’s try it!

I am planning to upgrade SSD. Is it possible to replace that SSD with a double-sided m2 ssd such as 4TB?

Yes it is possible thanks to the SSD slot (storage module is not solderen on MB).
