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 of which are understandable concerns. However, 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. Which, in my experience, is 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 pounds) while reducing its overall size (12.1 x 8.2 x 0.77 to 0.92 inches) by five percent. Critically, you still get a built-in kickstand on the bottom and a detachable keyboard that you move wherever you want. There’s also a decent number of ports, including two USB-C with Thunderbolt 4, one USB-A 3.2 jack, HDMI 2.1 and a combo audio port. That said, I do wish ASUS had found room for an SD card reader of some kind, though given the Zenbook Duo’s unique design, I get why that didn’t make it.
The Zenbook Duo’s detachable keyboard gives users a ton of flexibility when it comes to utilizing both of the laptop’s displays.
One of the Zenbook Duo’s most important design upgrades is a new “hideaway” hinge that reduces the gap between the laptop’s two screens. Not only does this make the laptop easier and more pleasant to use in dual-screen mode, it also allows the entire system to lay flat on a table, which is nice for drawing or sharing your screen with someone sitting opposite you. Unfortunately, while my review unit didn’t come with one, ASUS says its forthcoming Pen 3.0 will come bundled with the Zenbook Duo in the US, so you won’t need to pay extra for it.
Another small but appreciated improvement is the new pogo pins below the lower display, which provides a more secure and reliable way of keeping the laptop’s detachable keyboard topped up. In my experience, even after running multiple rundown tests that completely drained the Duo’s battery, I never had to charge up the keyboard on its own. It was always smart enough to sip electricity from the main system in the background, though it also has a built-in USB-C port for power just in case. On the flipside, if you’re not scared of typing on glass, you can still use the lower screen as a keyboard and touchpad, or as a place to display widgets for news, the weather, performance and more.
Displays
As someone who loves a desktop with dual monitors, I can’t overstate how nice it is to have similar built-in functionality on a laptop.
The standout feature on the Zenbook Duo continues to be its dual displays, and now for 2026, they look better than ever. Both OLED panels have a 144Hz refresh rate with a 2,880 x 1,800 resolution while also covering 100 percent of the DCI-P3 spectrum. And while its nominal brightness of 500 nits for SDR content is just OK, ASUS makes up for that with peaks of up to 1,000 nits in HDR. And to make both screens even more enjoyable, ASUS managed to shrink the size of their bezels down to just 8.28mm. That’s a reduction of 70 percent compared to the previous model, so now there’s even less getting in the way of you utilizing these screens to their fullest.
Performance
The Zenbook Duo can be configured with a range of new Intel Core Ultra 7 and Core Ultra 9 processors, including the X9 388H chip used on our review unit. For general use and productivity, the laptop is super smooth and responsive, though that shouldn’t be a surprise coming from Intel’s latest top-of-the-line mobile CPU. However, for those seeking max performance, some of the benchmark numbers aren’t quite as impressive as you might expect. That’s because ASUS has limited the Duo’s TDP (thermal design power) to 45 watts — which is shy of the chip’s 80-watt turbo power limit.
The kickstand in back adds a bit a bulk, but it’s better than not having one at all like with Lenovo’s Yoga Book.
In PCMark 10, the Zenbook Duo only managed a score of 7,153 compared to 9,651 from a Dell XPS 14, despite the latter having a lower-tier Intel Core Ultra X7 358H processor. That said, in other tests like Geekbench 6, the Duo had no trouble staying on top with a multicore score of 17,095 versus 9,651 for the Dell.
Another pleasant surprise is that because the Duo’s chip comes with Intel’s upgraded Arc B390 integrated GPU, this thing has plenty of oomph to game on, let alone edit videos or other similar tasks. In Elden Ring at 1,920 x 1,200, the Zenbook maintained a relatively stable framerate between 55 and 60 fps on high settings, which is great considering this thing doesn’t have discrete graphics. This means as long as you don’t mind fiddling with game options a bit, you should be able to play newer AAA games without too much trouble.
Battery life
The left side of the Zenbook Duo features a full-size HDMI connector along with a USB-C port, plus a backup USB-C jack for charging the detachable keyboard.
You’d think a laptop with two displays would be super power hungry. However, by increasing the capacity of its cell from 75WHrs to 99WHrs, ASUS has made the Zenbook Duo’s endurance (or lack thereof) a complete non-issue. On PCMark 10’s Modern Office rundown test, the laptop lasted 18 hours and 33 minutes in single-screen mode. Granted, that’s nearly four hours less than what we got from MSI’s Prestige 14 Flip AI+, but considering that’s the longest-lasting notebook we’ve ever tested, I’m not bothered. When compared to ASUS’ own Zenbook A14 (18:16), things are basically a wash, which I think is a win for the Duo, as the A14 is meant to be an ultralight system with an emphasis on portability and longevity.
Obviously, battery life takes a hit when you’re using both displays. However, when I re-ran our battery test with its two displays turned on, the Duo still impressed with a time of 14:23. This is more than enough to give you the confidence to set this thing up in dual-screen mode even when an outlet isn’t close at hand. Thankfully, for times when you do need a power adapter, the charging brick on ASUS’ cable is rather compact, so it’s not a chore to lug it around.
Wrap-up
The Zenbook Duo’s battery life is good enough you won’t always need its power brick. Thankfully, when you do, ASUS’ 100-watt adapter is relatively compact.
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.
