Stuff Verdict
Asus streamlines what was already a productivity prodigy, while new Intel hardware brings impressive power gains. It’s a niche laptop, but the latest Zenbook Duo does what it does exceptionally well.
Pros
- Same fantastic, flexible form factor made even sleeker
- iGPU now goes toe-to-toe with some dedicated graphics chips
- Considerable battery gains between generations
Cons
- Extra weight to carry (and more to pay) if you don’t intend to use both screens on the regular
- Stylus still a bit of a hanger-on
Introduction
Doubling up on displays has long been a great way to give your productivity a push, but that’s easier said than done on a laptop… unless you have a Zenbook Duo on your desk. Asus’ experiments with dual-screen notebooks of varying shape and size paid off big time when the original model made its debut in 2024, and now the firm is back with a faster, fettled version.
More than just a 2024 Asus Zenbook Duo with a few styling tweaks, the 2026 sequel brings its two OLEDs closer together for a more seamless experience. It also adds a bigger battery, more effective cooling, and marks my first unconstrained access to Intel’s new Core Ultra Series 3 processors. The silicon that previously used the (infinitely cooler) Panther Lake codename promises major gains on the graphics front, along with a big efficiency boost.
The travel-friendly dimensions and clever detachable keyboard haven’t gone anywhere, but neither has the outlandish asking price. An entry-grade Zenbook Duo starts around the $2500/£2500 mark and climbs higher as you step up on spec. Use one for any length of time, though, and that starts to seem like a bit of a bargain.

Design & build: between the lines
I’m not surprised the 2026 Zenbook Duo sticks closely to the formula established by the 2024 iteration: Asus went through a lot of reinventing the wheel with things like the one-and-a-half screen Zenbook Pro 14 Duo before it reached dual display setup that works as well as this one.
It looks like a regular 14in laptop when closed, albeit a little on the chunky side. Inside though, there’s a second screen where you’d normally find the keyboard, and enough of a gap between the two for a detachable Bluetooth ‘board to sandwich between. An integrated kickstand then lets you pick between four working modes: laptop, dual screen with the keyboard detached, desktop mode with the two screens in portrait orientation, or a fully flat sharing mode so two people on opposite sites of a table get a screen each.
The big change for this generation is a new hideaway hinge, which shrinks the gap between the two displays to just 8.28mm. It’s not invisible, but as close as you can get to it without paying a small fortune for a foldable display. Asus has also managed to reduce the overall footprint by 5%, which makes for an impressively compact system.
It hasn’t gotten any lighter, but that’s because you’re getting a battery that’s almost 20% higher capacity, which is a fair tradeoff in my book. I had no complaints slipping the 1.65kg machine into my backpack for a day of remote working. It helps that the power brick is very compact too.
There’s a decent selection of ports at the sides, with twin Thunderbolt 4 Type-C ports, one USB 3.2 Gen 2 Type-A, a full size HDMI 2.1 video output, and a 3.5mm headset port. The integrated webcam supports Windows Hello facial recognition, which is handy as there’s no fingerprint sensor. There’s also stylus support, though Asus still doesn’t give you anywhere to store one with the tablet itself.
Everything feels impressively sturdy, with no unsightly wobbles from the touchscreen when propped up on the kickstand. The keyboard sits firmly in place with magnets, making it feel like any other 14in ultraportable when in laptop mode. Asus has coated the whole thing in its hard-wearing Ceraluminum finish, which effortlessly resists fingerprints and didn’t pick up any surface scratches during my time with the Zenbook Duo.
Screen & sound: double whammy
What’s better than an absolute stunner of a 14in display? Having two of the things side-by-side, of course. The Zenbook Duo’s OLED panels have gloriously detailed 2880×1800 resolutions, with the 70% skinnier bezel arrangement helping content to flow more seamlessly between the two. I barely noticed it after a few minutes of web browsing in full screen.
Colours are vibrant, with excellent sRGB and DCI-P3 coverage that’ll keep creative sorts very happy indeed. Viewing angles are excellent and a new type of screen coating has helped reduce light reflections, if not quite to the level of a matte panel. Contrast is superb and black levels are as deep as I’d expect from OLED. More importantly, the two panels are identical, with no discernible difference in colour tone.
The 2026 edition has seen refresh rates climb to 144Hz (up from 120Hz on the 2024 model), helping animations and scrolling screen elements feel even smoother in motion. They support 48-144Hz variable refresh in Windows too, which helps maximise battery life without introducing any judder. It makes a welcome difference in games as well.
Brightness is the other area Asus has really stepped up between generations. The Lumia Pro panel is Dolby Vision certified for 1000 nits peak brightness in HDR now, while standard dynamic range content maxes out at a very respectable 500 nits – something the old model could only manage with HDR video. The pair easily shine bright enough for comfortable working and you can still control each panel independently, say when using the bottom panel as an input device.
Sound has also taken a step up this year, with six separate speaker drivers – four woofers and two tweeters – delivering plenty of volume and a great tonal balance for an ultraportable laptop. Treble is a little peaky when you really crank things up, but there’s a respectable amount of low end for something so svelte.
Keyboard & touchpad: I’ll take mine to go
While it’s magnetically held in place over the second screen, typing on the Zenbook Duo’s detachable keyboard felt just like a regular laptop. That’s impressive, given how slim the thing is once you pop it off. Asus has redesigned the key switches for extra travel, making it that bit more comfortable to tap away at.
Almost the entire board uses full-size keys, with just the function row and arrow keys shrinking down to fit. The island-style layout never felt cramped and the backlight perfectly illuminates each key legend. There’s zero latency while docked to the laptop, with pogo pin connectors ensuring the keyboard’s battery will always be charged when you next come to use it wirelessly. Battery life has also increased massively, lasting over 11 hours with the backlight or more than 50 without it. I never dislodged it accidentally while typing, either.
The touchpad beneath it has a hydrophobic coating that gives smooth, friction-free finger movement. It recognises a bunch of Asus-specific smart gestures as well as Windows’ own, and has a mechanical movement with just the right amount of physical feedback to let you know a click has registered.
With no built-in feet and a very flat shape, the keyboard sits fully flat on a desk once separated from the laptop, which I didn’t always find comfortable. It was perfect when placed on my lap though. This is the arrangement I’d use for air travel, with the kickstand able to fit both screens onto a very narrow tray table.
You can of course ditch the keyboard altogether and use the bottom touchscreen instead. Asus lets you get really granular with the layout, assigning parts of the screen for QWERTY keys, a numerical keypad, virtual touchpad, handwriting input, or bank of context-sensitive shortcuts. Multi-finger gestures swap between them all; they take some time to learn but are then much faster than picking from a menu.
Haptic vibrations try to give some sense of physical feedback, but I barely felt it even on the highest strength setting. I’d also like to see more third-party support for creative apps, rather than having to manually create your own banks of shortcuts. Still, the flexibility afforded by this dual-screen design puts a traditional laptop to shame.
Performance & battery life: Panther Lake is the real deal
Asus was the first brand to put a Panther Lake-powered laptop in my hands, outside of Intel-approved preview sessions. The top-tier Core Ultra X9 Series 3 388H used here has four performance cores, four efficiency cores and four low-power efficiency cores, which max out at a heady 5.1GHz. My review unit paired it with 32GB of RAM and 2TB of SSD storage.
Officially, single-threaded performance should see around 10% performance gains from the previous generation. Multi-threaded tasks are up to 26% faster. That absolutely bore out in my testing, with synthetic benchmark scores that put Acer’s Predator Triton 14 AI in the shade. Multi-core tests even eclipsed the 24-core Ultra 9 275HX seen in the Predator Helios Neo 16S AI. AI processing also sees big gains, depending on the software, thanks to an upgraded NPU.
Naturally that translates to fantastic desktop performance, with creative apps like Photoshop feeling effortless even when loaded down with massive files. Video editing and 3D rendering are no trouble either. It’s almost overkill for word processing and web browsing. For an ultraportable machine, there’s a serious amount of oomph here.
| Asus Zenbook Duo (UX8407AA) productivity benchmark scores | |
| Geekbench 6 single-core | 3025 |
| Geekbench 6 multi-core | 17,201 |
| Geekbench AI | 7391 |
| Speedometer 3.1 | 39.3 |
The X in X9 then indicates you’re getting Intel’s most powerful integrated graphics – an Arc B390 based on new Xe3 architecture, which the firm reckons is a whopping 170% faster than the last-gen model. 12 compute units and 16 MB of shared L2 cache are largely to thank for those gains, which in theory puts it ahead of laptops with dedicated RTX 4050 Laptop GPUs.
Those bold claims are the reason I’ve subjected this productivity-minded laptop to my full contingent of gaming tests. Admittedly the Zenbook Duo’s 2880×1800 resolution is asking a lot of the hardware, but as long as you avoid ray tracing effects and are realistic with the detail settings, dropping down to 1080p isn’t mandatory. Shadow of the Tomb Raider looks fantastic at Ultra details, and a 29fps average is console-quality performance.
Full HD is really the sweet spot, though. At the same detail settings I got 71fps. Using the latest version of Intel’s XeSS upscaling, it managed an even smoother 81fps – and that’s without any sort of frame generation. Gears Tactics hit a very playable 58.2fps at an even higher 1920×1200 resolution.
More intensive modern titles like Cyberpunk 2077 virtually demand frame gen to hit playable frame rates, even without ray traced lighting, but XeSS’ new 3:1 ratio really makes the difference here. At 1080p it managed a very smooth 90.9fps, though a quirk of that game and certain types of upscaling meant it couldn’t be set to full screen.
Intel really has delivered the goods here, meaning mobile gamers should now give serious thought to spending any extra on a machine with mid-tier dedicated graphics.

| Shadow of the Tomb Raider (RT on) | 20fps | 33fps |
| Shadow of the Tomb Raider (RT off) | 29fps | 44fps |
The other big year-on-year improvement is to battery life, with Intel touting 40% efficiency gains. It helps that Asus has also found room for a 99Whr cell, a significant boost over the 75Whr unit seen on the outgoing Zenbook Duo.
How you use this laptop dictates how long it’ll last away from the mains, with dual screen use naturally draining its power reserves faster than when sticking solely with one display. That said, I was routinely squeezing 10+ hours of typical desktop use, which for me includes image editing, video streaming and more browser tabs than I care to mention – and that was with both screens going at the same time.
For pure video playback I never quite managed Asus’ claimed 32 hours in single-screen (or 18 with both screens on), but I wasn’t far off. This is now an all-day laptop no matter how you use it. 100W USB PD support lets you top up using universal power bricks if the official one isn’t to hand, and it’ll get more than 60% refuelled in an hour.
Asus Zenbook Duo (UX8407AA) verdict
Asus already had the best dual-screen laptop out there, but for 2026 the Zenbook Duo has evolved almost entirely for the better. The slimmed-down screen bezels are the next closest thing to having one giant, unbroken display, while the smaller footprint makes it even more portable.
Intel’s new hardware has then brought strong desktop performance, a welcome boost to battery life, and the sort of gaming abilities you would’ve needed a dedicated graphics card for a few generations ago. It makes what was already an incredibly flexible machine even more so.
The premium pricing will mean it’s unlikely to convince dual screen doubters to make the jump from traditional laptops costing much less, but if portable productivity is a top priority, look no further.
