ASUS Zenbook Duo (2026) review: Two screens really are better than one

Source: Engadget

It takes time for novel designs to catch on. But even so, I am still wondering why the ZenBook Duo hasn’t had a bigger impact on the market after ASUS released its first true dual‑screen laptop two years ago. Notebooks like these provide the kind of screen space you’d typically only get from a dual‑monitor setup, but in a much more compact form factor that you can easily take on the road. It could be that people were wary of an unfamiliar design, shorter battery life, or buying a first‑gen product — all understandable concerns.

Now that ASUS has given the ZenBook Duo a total redesign for 2026, the company has addressed practically all of those barriers to entry while making it an even more convincing machine for anyone who could use more display space. In my experience, that’s pretty much everyone.

Editor’s note: The 2026 ASUS ZenBook Duo is expected to be available for pre‑order sometime in late February, with general availability slated for March.

Design

For the new model, ASUS didn’t mess with the laptop’s basic layout too much. Instead, the company polished and tightened everything up, resulting in a system that:

• Weighs about the same (3.6 lb)
• Is roughly five percent smaller (now 12.1 × 8.2 × 0.77–0.92 in)

Critically, you still get a built‑in kickstand on the bottom and a detachable keyboard that you can move wherever you want.

Ports

• 2 × USB‑C with Thunderbolt 4
• 1 × USB‑A 3.2
• HDMI 2.1
• Combo audio jack

I do wish ASUS had found room for an SD‑card reader, though given the Duo’s unique design, I understand why that didn’t make the cut.

Notable upgrades

• Hideaway hinge – Reduces the gap between the two screens, making dual‑screen mode more pleasant and allowing the whole system to lay flat on a table (great for drawing or sharing the screen).
• Pen 3.0 bundle – In the US, the forthcoming Pen 3.0 will be bundled with the Duo, so no extra cost.
• Pogo pins under the lower display – Provide a more secure, reliable way to keep the detachable keyboard charged. Even after multiple “rundown” tests that fully drained the Duo’s battery, the keyboard never needed a separate charge; it siphoned power from the main system, though a USB‑C port is also available for direct charging.

If you’re not scared of typing on glass, you can still use the lower screen as a keyboard/touchpad or as a place to display widgets (news, weather, performance, etc.).

Displays

The standout feature on the ZenBook Duo remains its dual displays, and for 2026 they look better than ever.

• Panel type: OLED (both screens)
• Refresh rate: 144 Hz
• Resolution: 2,880 × 1,800
• Color gamut: 100 % DCI‑P3
• Brightness: 500 nits (SDR) with peaks up to 1,000 nits (HDR)
• Bezels: 8.28 mm (≈ 70 % reduction vs. previous model)

The slimmer bezels mean less distraction and a more immersive dual‑screen experience.

Performance

The Duo can be configured with a range of new Intel Core Ultra 7 and Core Ultra 9 processors, including the X9 388H chip used in our review unit.

• General use & productivity: Super smooth and responsive, as expected from Intel’s top‑tier mobile CPU.
• Thermal design power (TDP): Limited to 45 W (vs. the chip’s 80 W turbo limit), which caps peak performance in sustained workloads.

Benchmarks

While PCMark 10 shows the Duo trailing the XPS 14, Geekbench 6 demonstrates its multicore strength.

Integrated graphics

The Duo’s chip includes Intel’s upgraded Arc B390 integrated GPU, which provides enough oomph for light gaming and video editing. In Elden Ring at 1,920 × 1,200 on high settings, the laptop maintained a stable 55–60 fps—impressive for a system without discrete graphics.

Battery life

Two displays might suggest a power‑hungry machine, but ASUS increased the battery capacity from 75 Wh to 99 Wh, making endurance a non‑issue.

• PCMark 10 Modern Office (single‑screen mode): 18 h 33 min
• PCMark 10 Modern Office (both screens on): 14 h 23 min

For comparison, the MSI Prestige 14 Flip AI+ achieved about four hours more in single‑screen mode, while ASUS’s own ZenBook A14 posted 18 h 16 min. The Duo’s numbers are therefore competitive, especially given its larger form factor and dual‑screen capability.

Overall, the 2026 ASUS ZenBook Duo addresses the major concerns that held back its predecessor—design quirks, limited battery life, and modest performance—while delivering a compelling dual‑screen experience that could appeal to a broad audience.

Wrap‑up

I’m a believer that one day people will eventually embrace typing on screens with laptops just like they have for smartphones. However, even if you’re not willing to make that jump just yet, the ZenBook Duo still has all of its bases covered. Its detachable keyboard gives you a pleasant experience while freeing up the bottom of the notebook to be a second display. This allows you to have something similar to a traditional dual‑monitor desktop but in a chassis that you can easily take on the road without any major compromises.

The 2026 ZenBook Duo combines a compact design with strong performance, plenty of ports, and surprisingly good battery life. Sure, it’s a touch heavier than a typical 14‑inch laptop, but its two screens more than make up for a little added weight and thickness. That leaves price as the Duo’s remaining drawback, and starting at $2,100 (or $2,300 as reviewed), it certainly isn’t cheap.

However, when you consider that a similarly equipped rival like a Dell XPS 14 costs just $50 less for a single screen, that price difference is rather negligible. Alternatively, if you opt for a more affordable ultraportable and then tack on a decent third‑party portable monitor, you’re still likely looking at a package that costs between $1,500 and $1,800. Plus, that setup is significantly bulkier and more annoying to carry around.

So while the ZenBook Duo might be an unconventional pick right now, it has all the tools to deliver unmatched portable productivity, and I don’t think it will be too much longer until the masses catch on.
