Greatly expanding on the previous model, which had the same name and a much smaller second display, the new Zenbook Duo sports two 14-inch OLED panels and a detachable keyboard. Theres some performance inconsistencies with the two configurations I tested, but this is easily the best dual-screen laptop ever made.

The $1,500 base configuration includes an Intel Core Ultra 7 155H chipset, 16GB of RAM, a 512GB SSD, and two 14.0-inch FHD+ OLED panels running at 60Hz. Spend just $200 more, and you get a Core i9 185H, 32GB of RAM, a 1TB SSD, and two 14.0-inch 3K OLED panels at 120Hz.
On paper, its toss-up as to which of these configurations is the better bargain. On the one hand, the entry-level configuration is $560 less than the Lenovo Yoga Book 9i, the Zenbook Duos direct competitor. Lenovos dual-screen laptop costs $2,060 with the same Core Ultra 7 155H, 16GB of RAM, a 1TB SSD, and two 13.3-inch 2.8K OLED displays. But even when configured with a faster chipset, twice the RAM, and larger displays with faster refresh rates (the Lenovos top out at 60Hz), the Zenbook Duo is still $360 less.
Ill get into more differences between these laptops below, but based on price alone, Asus offers the more attractive machine. I reviewed both Zenbook Duo configurations, and as well see, the entry-level model is the most attractive.
Design
Ive reviewed several laptops that offer two displays, either real ones, as with the Zenbook Duo and Lenovo Yoga Book 9i, or virtual ones, as with foldable laptops like the HP Spectre Foldable PC and the Lenovo ThinkPad X1 Fold. Although the two approaches promise tons of flexibility, their implementations are very different.Foldable laptops have large OLED panels that fold down the middle, turning them from very large tablets into smallish clamshell laptops. By propping them up and using them with external keyboards, they can serve as large desktop machines with a single expansive display. In particular, the Spectre Foldable PC demonstrates the viability of these 3-in-1 laptops.
The dual-screen laptop is different. It offers a superior clamshell mode with a physical keyboard on the second, larger display. In the Zenbook Duos case, were talking about two 14-inch panels. It can also be used as a desktop, with each display standing side-by-side in portrait mode and in a vertically stacked configuration with each display in landscape mode.
However, its not one large, seamless display like foldable PCs. Notably, the form factor doesnt work as a standard tablet, although its displays both support active pens, and its second display can be used for digital drawing and handwriting when the keyboard is removed. None of the laptops can comfortably be used in hand like lighter, simpler tablets.
While theyre similar in functionality, the Zenbook Duo and Yoga Book 9i arent identical in their designs. First, the Zenbook has a kickstand built into the second display that holds the laptop securely in both desktop and vertically stacked modes. Its a simple, yet effective implementation. The Yoga Book 9is origami stand is more complicated to set up and is another piece to carry around. I found Lenovos approach workable during my review, but I like the Zenbooks built-in kickstand much better.
Overall, the Zenbook Duo is an incredibly well-built laptop that felt light enough with or without its keyboard. It can be carried around either with the keyboard in place or without it, unlike the Yoga Book 9i, which cant hold its keyboard when closed. That makes the Zenbook heavier and thicker, but much more convenient as a self-contained unit.
Second, the Zenbook Duos keyboard is full-sized compared to the Yoga Book 9is half-sized version. While the Yogas keyboard leaves half the second display available for use, its not as comfortable for typing, and it lacks a physical touchpad. Instead, it relies on a virtual facsimile. The Zenbooks keyboard provides large keycaps, tons of spacing, and light, snappy switches. Its an excellent keyboard that might not match Apples Magic Keyboard for sheer precision, but its close enough.
The Zenbooks physical touchpad, although mechanical (the ThinkPad X1 Fold offers a haptic touchpad), was preferable to Lenovos software version. And when used in desktop mode, the Yoga Book 9i requires an external mouse.
Again, I liked the Yoga Book 9is keyboard during my review, but I like the Zenbooks better. To top it off, the Zenbooks keyboard connects via strong magnets and pogo pins, keeping it firmly in place while charging it during use.
It connects via Bluetooth when used externally. The Zenbook Duo also has a software keyboard that can be accessed with a six-finger tap, and it works as well as all virtual keyboards its OK for tapping out a quick text, but not for even short copy. There are also several tools available on the second screen, including a handwriting panel, a control panel, and a virtual numeric keypad.
Finally, the Yoga Book 9is displays are separated by its excellent Soundbar speaker and microphone, and theres a smoother transition between them. When sitting in desktop mode, the Zenbook has an angle that works well in clamshell mode, but breaks up the horizontal placement. The Zenbook works much better with both displays stacked vertically which is a lot more comfortable to configure using the kickstand.
Overall, Id rate the Zenbook Duo as the best dual-screen laptop Ive used in clamshell and stacked modes, but its not as good in desktop mode.
Ports and webcam
Unlike the other dual-display laptops Ive discussed, the Zenbook Duo has the usual 14-inch laptops connectivity. That is, it has both modern Thunderbolt 4 ports and legacy USB-A and HDMI connectivity. Thats because, once again, the Zenbook is more of a clamshell notebook design that happens to have two displays. Unfortunately, Asus didnt include an SD card reader, which would have pleased creators. Wireless connectivity remains a generation behind with Wi-Fi 6E and Bluetooth 5.2, while some recent laptops have made the leap to Wi-Fi 7.The webcam is a 1080p version, offering a quality image for videoconferencing. Thats lower than the 5MP webcam on the Yoga Book 9i, but its still quite serviceable and supports Microsofts Studio Effects feature that leverages the Meteor Lake Neural Processing Unit (NPU). An infrared camera enables Windows 11 facial recognition.
Displays
Foldable PCs have smaller virtual top and bottom displays that create smaller clamshell laptops. The Zenbook Duo isnt so limited. It sports two 14.0-inch 16:10 OLED panels in one of two resolution choices, Full HD+ (1920 x 1200) and 2.8K (2880 x 1800). The higher-resolution panels add the benefit of running at up to 120Hz, while the lower-resolution screens are limited to 60Hz. Subjectively, both display options provided bright, colorful images with OLEDs usual inky blacks. But the FHD+ panels werent as sharp, with noticeable pixelation in text. If, like me, you prefer the sharpest text possible, youll want to opt for the higher-resolution display.According to my colorimeter, all displays are excellent. The FHD+ version had slightly better colors on its primary panel, at 100% of both sRGB and AdobeRGB and 99% of DCI-P3 versus 96% of AdobeRGB and 100% of DCI-P3 for the secondary panel. Accuracy was lower than some OLED panels at a DeltaE of 1.37 and 1.07 (1.0 or less is considered excellent), respectively, and brightness was good, but not great at 371 and 365 nits. Blacks were perfect on both, with incredibly high contrast. The 2.8K panels had similar brightness, slightly wider colors, and greater accuracy at a DeltaE of 1.01 and 0.67.
Regardless of your chosen model, youll get spectacular colors and awesome contrast that will please productivity users, creators, and media consumers alike. High dynamic range (HDR) content will look great, although brightness isnt high enough to do it full justice. Only Mini-LED displays, like those on Apples MacBook Pros, offer enough brightness for the best HDR performance.
Performance
I reviewed the Zenbook Duos entry-level and high-level configurations, which use Intel Meteor Lake 14th-gen chipsets. I measured performance of the 28-watt Core Ultra 7 155H with 16 cores (six Performance, eight Efficient, and two Low Power Efficient) and 22 threads running at up to 4.8 GHz, with 16GB of RAM. I also tested the Core Ultra 9 185H that has the same core and thread count, runs up to 5.1GHz, and consumes 45 watts and has 32GB of RAM. The Zenbook Duo is the first laptop weve tested with the Core Ultra 9 185H.Its not often that we have a chance to test different chipsets in otherwise identical laptops. The Zenbook Duo is, at heart, a thin-and-light laptop, which means it has limited space to move air and keep things cool. That means a higher-power chip like the Core Ultra 9 185H wont necessarily perform that much better than the lower-power Core Ultra 7 155H. In our suite of benchmarks, the Zenbook Duo yielded some unsurprising and inconsistent results.
In our CPU-intensive benchmarks, the Core Ultra 9 was faster than the Core Ultra 7, but not by much. Strangely, its score in the PCMark 10 Complete benchmark was considerably lower. Either the chipsets just not much faster or the Zenbook Duo cant take advantage of it, as thermal throttling happens earlier and more often.
When I ran the 3DMark Time Spy benchmark, the Core Ultra 9s Intel Arc graphics scored very poorly. In both balanced and performance modes, the ostensibly faster chipset scored roughly half that of the slower chipset, coming in at the same scores as the previous Intel Iris Xe graphics. That indicates some serious and troubling throttling (or an issue with the firmware). While neither model got overly warm on the chassis bottom, the high-end models fans spun up more often and ran longer. Neither was ever annoyingly loud, however, even in performance mode that was significantly faster.
Compared to the other dual-screen laptops weve tested, the Zenbook Duo is consistently faster with the Core Ultra 7. Thats particularly true when compared to the two foldable PCs. Its important to note that the Lenovo Yoga Book 9i has recently been updated to Meteor Lake, so its likely to be more competitive.
The Zenbook Duo is fast enough for very demanding productivity workflows when in performance mode. However, like all laptops with integrated graphics, it wont please creators who use apps that can leverage a discrete GPU. Intel Arc graphics are faster than the older Intel Iris Xe graphics (with the Core Ultra 7), but they still fall short of entry-level discrete graphics. Its not a gaming laptop.

With both displays running, the Zenbook Duo lasted for about a half hour less in each test. The Core Ultra 9 model, on the other hand, managed just 4.75 hours of web browsing and around eight hours looping our test video with just one display active. I didnt bother running the tests with both displays turned on.
The low-end model achieved average results comparable to single-display laptops even with both displays active, making that Zenbook Duo model a very good performer. Theres no significant battery life penalty from running both displays. While the laptop may not last for a full days work, thats true of most Windows laptops. Only Apples highly efficient MacBooks managed a lot more.
The first great dual-screen laptop
The Zenbook Duo is an extremely well-built dual-screen laptop with some key advantages. Its a better dual-screen clamshell laptop than the competitors and a great clamshell laptop in general. Its also the best at stacking its dual displays in a vertical orientation, thanks to a simple, yet effective built-in kickstand. But its not as good in desktop mode.At the same time, the low-end models performance is superior to those weve tested, with surprisingly good battery life. The high-end configuration, on the other hand, demonstrated inconsistent performance and much worse battery life. So, I can strongly recommend the entry-level model (which is also the best value), with the only caveat being that the OLED displays arent quite as sharp. The high-end model, while enjoying higher-resolution displays, doesnt offer much else to justify its higher price.
