Asus Zenbook Duo OLED review - The multi-screen convertible now with Intel Arrow Lake
Multitasking monster.
The Zenbook Duo is one of the first devices to be equipped with the new Arrow Lake mobile processors from Intel and it's still a highly interesting device thanks to its multi-screen concept. Two 14-inch OLEDs with a FHD resolution are installed in our test device, which helps its battery life in particular.Andreas Osthoff, 👁 Andreas Osthoff (translated by Daisy Dickson) Published 🇩🇪 🇫🇷 ...
Verdict - The Zenbook Duo delivers around 20 % more CPU/GPU performance thanks to Arrow Lake
In 2025, the Zenbook Duo continues to be an extremely exciting convertible thanks to its two OLED screens. Since both screens offer the same features, productive work is no problem and windows can be moved without any scaling issues. Thanks to its built-in kickstand and great detachable keyboard, there are lots of ways to use the Zenbook Duo. The disadvantage of its overall concept is its rather high weight and case thickness of just under 2 cm. In addition, its maintenance options are very limited, as you have to take apart half the device to access the M.2 2280 SSD. Asus has also changed the distribution of its ports slightly—there is now a USB-C port on both sides, which is very handy.
The Zenbook Duo is one of the first devices to use the new Arrow Lake H mobile processors from Intel. These are the direct successors to the Meteor Lake generation and the performance of both the processor and the graphics card has been increased by more than 20%. However, its power limits remain low—especially under continuous load—and the laptop can't fully make use of the Core Ultra 9 285H's performance potential. Unlike the efficient Lunar Lake processors, the Arrow Lake chips use a weaker NPU, which is why the official Copilot+ certification is missing on this device. Even so, functions such as the webcam's Studio Effects or live subtitles are still available, meaning this doesn't make a huge impact on end users.
As with last year's model, you have a choice between two different OLED versions. The 2.8K panel at 120 Hz is reserved for the most expensive version costing around $2,600, while our test device, which can be had for approximately $2,170, is equipped with the 1200p model at 60 Hz. The lower frequency is the most noticeable aspect but subjectively, the screen's picture still looks very good, and both screen models' specifications are comparable apart from their resolution and frequency. The laptop's power consumption and, as a result, its battery life, benefit from the 1200p OLEDs, which should definitely be taken into account for a mobile device.
The Asus Zenbook Duo is still pretty much unrivaled because no other current device on the market can be used in such a versatile way without having to make any real compromises. Lenovo pursues a similar concept with its Yoga Book but in that case, its wireless keyboard has to be transported externally and typing doesn't feel as comfortable—plus, its overall performance is simply significantly lower.

Last year, Asus launched its Zenbook Duo, an interesting convertible that was very versatile and featured two 14-inch OLED panels and a detachable Bluetooth keyboard. Above all, the two identical panels proved to be a great advantage during use. At that time, the Meteor Lake processor Intel Core Ultra 9 185H was installed and now, the 2025 version of the Zenbook Duo is one of the first devices to be equipped with the brand new Arrow Lake mobile processors from Intel. In our test device (which has an MRSP of around $2,170), the new Core Ultra 9 285H works in conjunction with 32 GB RAM and a 1-TB SSD. Unlike last year's test device, two Full HD OLEDs at 60 Hz are now installed, which is why its picture quality suffers somewhat but its battery life is better. The 3K OLEDs at 120 Hz are still available in the variant costing approximately $2,600 (32 GB RAM, 2 TB SSD).
Specifications
Case & connectivity
In general, the design of the new Zenbook Duo doesn't differ from its predecessor. Visually, we can see lots of similarities to the regular Zenbooks, including its large ProArt logo on the screen lid. The build quality and stability of the case (magnesium alloy) are very good. In addition to the regular screen, the Zenbook Duo features another OLED touchscreen on the top of the base unit. Together with its detachable keyboard, this gives you a convertible with a wide range of possible uses. In order to prop up the Zenbook Duo, there is a built-in kickstand on the bottom, which generally works well. However, the solution still isn't ideal if you want to use the two screens in so-called desktop mode (like an open book), as the main screen then folds back slightly. All-in-all, however, the concept still works very well. Still, with a thickness of just under 2 cm and a weight of almost 1.8 kg (including the keyboard), it is also significantly heavier and thicker than regular 14-inch convertibles.
Asus has taken our criticism to heart when it comes to the laptop's connections and has now changed their layout, as there is now a USB-C port (Thunderbolt 4) on both sides. In addition, it now uses a modern W-Fi 7 module and its transfer rates were great during our test using our reference router from Asus. Its 1080p webcam does its job and advanced Studio Effects are also supported. Officially, however, the new Arrow Lake devices are not Copilot+ devices, as the NPU is too weak. In addition to Studio Effects, the Zenbook also supports Windows live subtitles, among other things. However, accessing all the components is more difficult due to the second screen. You first have to release two connections via a small flap on the underside before the case can be taken apart further. An M.2 2280 SSD is installed inside, which can theoretically be replaced—but this requires you to remove the antenna cables, connection cables and part of the mainboard.

Sustainability
The Zenbook Duo's case is made from 90% recycled materials and its packaging is 100% recycled. The device also meets various environmental standards such as Energy Star, EPEAT Gold and RoHS. Information on the CO2 footprint created during its production is not provided, and no repair instructions are available.
Input devices
In addition to the two touchscreens, the device of course also supports pen input with the supplied Asus Pen 2.0, which works very well. However, the true highlight in our eyes is the detachable keyboard unit, which is very securely attached to the case via magnets. In addition to the keys having a travel of 1.4 mm and quiet keystrokes, they boast a very high rigidity, leading to a very comfortable typing experience. In this aspect, the Zenbook Duo even has an advantage over some regular laptops. The ClickPad also works very well and gives off nice, muffled clicking noises.
The Bluetooth keyboard has a battery and can be charged via USB-C, but as soon as it is placed on the base unit, it connects to the pogo pins and the keyboard is charged automatically. According to Asus, the battery in the keyboard has a runtime of up to 24 hours. The three-level white backlighting can be activated by a sensor.
Display - Dual OLEDs at 1200p
The Zenbook Duo is equipped with two identical 14-inch OLED panels, which is why working with both screens is possible without any issues (identical picture quality, no scaling problems when moving windows). Last year's test device had two high-resolution OLEDs with a 2.8K resolution and a frequency of 120 Hz, while our current test configuration has two full-HD OLEDs at 60 Hz. Apart from this, the other features are the same. The screens' brightness can be adjusted automatically via a sensor, but the color temperature cannot.
Their picture quality is generally very good and a slight raster effect can only be seen on bright content if you look very closely—but this shouldn't be noticeable during everyday use. We measured a maximum SDR brightness of 362 cd/m² on average and, in combination with the low black level, this results in a high contrast ratio that is typical of OLEDs. In HDR mode (which you have to activate manually), we noted a maximum of 625 cd/m² when depicting small image sections and 601 cd/m² when showing an almost completely white image. The screens' response times are very fast and there is no backlight bleeding, although they do use PWM flickering at a frequency of 480 Hz at brightness levels of 86% and less.

We analyzed the laptop's display using the professional CalMAN software. As usual, Asus provides various profiles and the profile "Native" is active by default, which unfortunately depicts the colors a little oversaturated. The P3 profile is a very accurate profile straight out of the box. There is also an sRGB profile and both color spaces are fully covered. We were unable to improve its display any further using our own calibration.

Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 480 Hz Amplitude: 14 % | ≤ 86 % brightness setting |  |
The display backlight flickers at 480 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 86 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 480 Hz is relatively high, so most users sensitive to PWM should not notice any flickering. However, there are reports that some users are still sensitive to PWM at 500 Hz and above, so be aware. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8564 (minimum: 5 - maximum: 343500) Hz was measured. | |||
Outdoors, the shiny screens struggle with reflections, especially in bright surroundings. Apart from a slight blue shimmer at wide angles (which is typical for OLEDs), we noted no problems with viewing-angle stability.
Performance - Arrow Lake-H
The new Zenbook Duo comes exclusively with the new Arrow Lake H processors from Intel (Core Ultra 7 or Core Ultra 9), which are combined with either 16 or 32 GB RAM (LPDDR5x-7467). The RAM is soldered on and cannot be expanded.
Testing conditions
Users can choose from four different energy profiles, which are also linked to the Windows settings. We carried out the following benchmarks and measurements in standard mode. The CPU performance can be increased slightly by using the other two modes, but this also leads to significantly louder fans.
| Energy profile | TDP | CB 2024 Multi | Time Spy Graphics | max. fan noise emissions |
|---|---|---|---|---|
| Whisper | 28 watts | 13,144 points | 3,726 points | 33.2 dB(A) |
| Standard | 60/35/24 watts | 16,632 points | 4,074 points | 39.8 dB(A) |
| Performance | 60/45/35 watts | 17,249 points | 4,103 points | 50.2 dB(A) |
| Full speed | 60/45/35 watts | 18,758 points | 4,105 points | 54.3 dB(A) |
Processor - Core Ultra 9 285H
Our test device is equipped with the new top-of-the-range model of the Arrow Lake H series, namely the Intel Core Ultra 9 285H. It is the successor to the Meteor Lake generation and features a total of 16 CPU cores (6x performance, 8x efficiency, 2x low-power efficiency). Further details on the new mobile processors are available in our analysis article. According to Intel, the Arrow Lake H chips once again operate in the 28-115 watt range, which is why the respective device's power limits and cooling again have a major influence on performance. In the case of the Zenbook Duo, we noted up to 60 watts for a short time, then 35 watts and under longer periods of load, its consumption leveled off at around 24 watts. As a result, the Core Ultra 9 285H's full performance potential can't be taken advantage of.
In direct comparison with the old Core Ultra 9 185H, we measured an advantage of around 20% across all benchmarks, which is a good result. However, its performance dropped quickly, which was particularly noticeable in the CB-R15 loop with short runs. After 25 runs, its multi-core performance plummeted by almost 40%. There is no further reduction in performance in battery mode. Further CPU benchmarks are available here.

System performance
There were also improvements in its system benchmarks compared to the predecessor model, but this won't be noticeable during everyday use, as the old Zenbook Duo was already a very responsive device. The system also copes very well with multi-screen operation and there were no stability problems during our test.

Storage device
A 1-TB version of the Western Digital SN5000S is installed in our test device, with 870 GB still available to the user after first starting up the laptop. The PCIe 4.0 SSD's performance was great during our test, remaining stable even under prolonged load. So there are no problems in this area. Further SSD benchmarks are listed in our tech section.

Graphics card
The Core Ultra 9 285H's integrated graphics card is called the Intel Arc Graphics 140T and is an improved version of the old Intel Arc Graphics with 8 Xe cores. It continues to use the Xe cores from the first generation, so technically, there is already a clear difference to the Intel Arc Graphics 140V of the current Lunar Lake models. All other technical details are available in our GPU analysis article.
During the synthetic benchmarks, the new 140T was around 20% ahead of the old Arc Graphics with 8 Xe cores, but the Arc Graphics 140V was practically on par. In the actual gaming benchmarks, however, the Lunar Lake GPU had a clear advantage in some cases. Compared to the old Zenbook Duo, however, it still had an advantage of more than 20%. The Intel iGPUs now also support Frame Generation in selected games, which makes a clear difference and we took a closer look at this in our GPU analysis. Its performance remains stable both in battery mode and under prolonged load.

Emissions & energy
Noise emissions
The two fans' overall noise development is comparable to that of the predecessor model. In standard mode, the cooling is often completely deactivated during simple tasks. Under higher load (e.g. gaming, CPU load or stress test), we measured a maximum of 39.8 dB(A), which is of course clearly audible, but not yet annoying. In whisper mode (which also offers sufficient performance for everyday tasks), the Zenbook Duo remains significantly quieter at a maximum of 33.2 dB(A). The two faster modes (performance & full speed), on the other hand, are unpleasantly loud at over 50 dB(A). There were no other electronic noises coming from our test device during the test phase.

Temperature
There are no major changes to its surface temperatures compared to the old model. The case stays very cool in idle mode and during simple tasks. Under load, we noted a hotspot in the upper middle area of the underside, but 47 °C is by no means critical and you can still place it on your thighs without any restrictions. The keyboard remains significantly cooler, although you naturally benefit from the fact that it is a separate component. During the stress test, the processor initially briefly reached 60 watts before leveling off at 35 watts for a few minutes and later at around 24 watts (the old model was ~20 watts).
(+) The maximum temperature on the upper side is 35.3 °C / 96 F, compared to the average of 35.4 °C / 96 F, ranging from 19.6 to 60 °C for the class Convertible.
(-) The bottom heats up to a maximum of 47.2 °C / 117 F, compared to the average of 36.8 °C / 98 F
(+) In idle usage, the average temperature for the upper side is 24.1 °C / 75 F, compared to the device average of 30.3 °C / 87 F.
(+) 3: The average temperature for the upper side is 31.5 °C / 89 F, compared to the average of 30.3 °C / 87 F for the class Convertible.
(+) The palmrests and touchpad are cooler than skin temperature with a maximum of 28.5 °C / 83.3 F and are therefore cool to the touch.
(±) The average temperature of the palmrest area of similar devices was 28 °C / 82.4 F (-0.5 °C / -0.9 F).

Power consumption
The consumption measurements show the Full HD OLEDs to have an advantage compared to the 2.8K models that we tested in the predecessor model. Under load, however, the two models don't differ much, which isn't really surprising given their identical power limits. We measured a maximum of 65 watts during the stress test, which quickly leveled off at 54 and then around 45 watts. In principle, the compact 65-watt power supply is therefore sufficient in size. However, its standby consumption of 1.1 watts is slightly too high and also higher than the old model (0.71 watts).

Runtimes
Nothing has changed about its 75 Wh battery, but the screens' lower resolution/frequency has had a positive effect on the laptop's battery runtimes. During the WLAN test at 150 cd/m² (corresponds to 70% of our test device's maximum SDR brightness) with an active display, its runtime increased from just under 9.5 hours to just over 11 hours. At full brightness, it we noted just under 8.5 hours compared to the predecessor's 7 hours. As expected, its runtime is reduced with two active displays, but 8:17 hours at 150 cd/m² and 6 hours at full brightness are still by no means bad results. In the video test at 150 cd/m² and with one screen, we even recorded almost 17 hours, which is nearly 3.5 hours more than before.
However, its better results are primarily due to the displays and not its new processor. So if you opt for a configuration with the 2.8K OLEDs, you can use the runtimes of our 2024 review as a guide. A full charge takes 110 minutes with the device switched on, with 80% of its capacity being available again after around 65 minutes.

Notebookcheck total rating
The Zenbook Duo continues to be a very exciting multi-screen convertible. The 1200p OLEDs in our test model don't quite achieve the picture quality of the 2.8K screens in the more expensive configuration, but they reduce its power consumption and thus increase the laptop's battery life. The new Arrow Lake processor offers around 20% more CPU performance than before but overall, the Zenbook Duo's power limits remain quite low (especially under prolonged load) and the full performance potential of the Core Ultra 9 285H cannot be exploited.
