Asus Zenbook Duo OLED (2024) convertible review: Multitasking champion with Core Ultra 9

All-rounder with two OLED screens. Asus takes multitasking to a new level with the new Zenbook Duo OLED. The versatile laptop impresses with two great 120 Hz OLED screens and a sophisticated operating concept. It also comes with the new Intel Core Ultra 9 185H and 32 GB RAM.

Asus' Duo series with two screens has been available for a few years now, but the secondary display has always been a small additional display. The new Zenbook Duo OLED UX8406MA, on the other hand, has two identical 14-inch OLED screens, making the device very versatile. In addition to an active stylus and a protective case, a Bluetooth keyboard with a touchpad is included, meaning that the Zenbook Duo can be used just like a regular laptop.

In terms of hardware, there are large similarities to the previously reviewed Zenbook 14, as the two OLED screens come either as Full HD models with 60 Hz or 3K models with 120 Hz. All variants are equipped with Intel's new Meteor Lake processors. Prices start at $1499; our test device is the high-end version with the two high-resolution OLED panels, the Core Ultra 9 185H, 32 GB RAM and a 2 TB SSD for $3999.99.

Case - Like a Zenbook 14, only thicker

The basic design of the Zenbook Duo is very reminiscent of the current Zenbook 14, as it also has the large Pro Art logo on the lid and both have the same feel. However, the Zenbook Duo comes in a dark gray (Inkwell Gray) and is heavier and thicker. The identical 14-inch OLED screen is installed on the top of the base unit, but a full Bluetooth keyboard with ClickPad can be placed on top. This is held securely in place by magnets and covers the entire base unit, not just part of it (like the Lenovo Yoga Book 9i). 

A large kickstand is built into the underside of the base unit, which allows for various styles of use. Of course, the Zenbook Duo can be used as a normal laptop with a normal keyboard, which is a big advantage over the Zenbook Pro Duo. On the other hand, users can remove the keyboard and use two displays on top of each other. Moreover, the device can also be set up like a book, but in this case it is not particularly stable on the desk and the design of the kickstand is not quite optimal.

In terms of quality, the metal chassis of the Zenbook Duo makes a very stable and solid impression; only the kickstand has a little play. We did not observe any creaking noises and the lid is very stable. The screen lid can be opened easily with one hand and the maximum opening angle is 180 degrees. The hinges, however, could be a little tighter, as the screen wobbles a little.

As previously described, the Zenbook Duo is naturally heavier at a total of 1.7 kg (1.39 kg for the device itself + 317 grams for the keyboard) and, at a height of almost 2 cm, thicker than conventional laptops such as the Zenbook 14 or convertibles such as the HPs Spectre x360 14 or Lenovo's Yoga 9i 14. But the dimension are roughly comparable with the Zenbook Pro 14 Duo, which also uses two displays. The 65-watt plug-in power supply is extremely compact and weighs just 191 grams, including the cable.

Equipment - Thunderbolt and HDMI

The ports of the Zenbook Duo correspond to the regular Zenbook 14: in addition to two Thunderbolt ports, users also have a regular USB-A port and a full HDMI output. However, the USB ports are all located on the left side of the base unit. The Bluetooth keyboard also has a USB-C port for charging, but this also works very conveniently via the pogo pins on the front of the base unit. As soon as the keyboard is latched into place, it automatically recharges. A card reader, however, is lacking.

Communication

The new Zenbook Duo is still not WiFi 7 capable, but a fast WiFi 6E module is installed, namely the AX211 card from Intel. In tandem with our Asus reference router, transfer rates were very high and stable. There were also no WiFi stability issues during testing.

Maintenance

In principle, the Zenbook Duo offers access to components such as the M.2-2280 SSD, the battery or the fan. However, in contrast to conventional laptops, the procedure is much more complicated. First, the kickstand on the underside has to be unscrewed, followed by another cover on the underside, which is attached with two screws. Underneath are two ribbon cables that need to be removed. Only then can the base of the laptop (secured with Torx screws) be removed. This is definitely not a job for inexperienced users and we also wanted to avoid damaging the test device, which is why we stopped the attempt at this point. Photos of the internals will be published as soon as possible.

Input devices - Zenbook Duo with full keyboard

The Zenbook Duo comes with an additional keyboard that is magnetically attached to the base unit. The attachment strength is very solid and the keyboard does not slip one millimeter during use. At the bottom there are contacts that connect the keyboard to the notebook and charge it at the same time. When the keyboard is removed, it remains connected to the Zenbook via Bluetooth. There is a white backlight with three intensity levels, which can also be controlled automatically via an ambient light sensor.

Fundamentally, the keyboard characteristics are the same as on as the regular Zenbook 14, so there is a key travel of 1.4 mm and no compromises in the layout (compared to the Zenbook 14 Duo, for example). Long texts can be typed very comfortably and users have no disadvantages whatsoever compared to a conventional laptop/convertible. This also applies to the ClickPad, where the clicks are even quieter and feel more premium than on the Zenbook 14. Gliding properties are also very good.

Both screens are touchscreens and can naturally be used for inputs. This is where the included stylus comes into play, which works very well, but cannot be attached to the chassis. This is the Asus Pen 2.0 SA203H (4096 pressure levels), which is the same size as a regular pen and thus very comfortable to hold, even when used for long periods of time. It is charged via USB-C.

In addition, the lower touchscreen can be used as a virtual keyboard, whereby only the keyboard or the keyboard together with a simulated touchpad (under the keyboard or to the right of it) can be displayed. However, this is rather strange to use, as there is simply no haptic feedback when keys are pressed. However, in view of the good keyboard included with the laptop, we see no reason to use the virtual keyboard.

Display - Zenbook Duo with two great OLED panels

Subpixel grid

Like the regular Zenbook 14, the Zenbook Duo offers a choice between OLED panels with Full HD resolution (60 Hz) or 3K resolution at 120 Hz. Two identical Samsung panels are used, which is a huge advantage in terms of operation, since scaling problems are a thing of the past and users don't have the feeling that the second display is of poorer quality, as was the case with the Zenbook Pro 14 Duo. As soon as you remove the keyboard, the second screen is activated. Asus offers extensive options here with the ScreenXpert software, which allows for quick arrangement of apps on the two screens or for activation of the virtual keyboard. Everything works very well and after a little familiarization users can really get the most out of the two screens.

The two Samsung panels performed very well in our measurement tests and the results are very much identical (with minor deviations). The average brightness in SDR mode is 384 cd/m², which, together with the low black level, results in a very high contrast ratio. The subjective picture quality is also excellent, as all content on the 3K panel (2880 x 1800, 16:10) is razor-sharp and colors appear extremely vibrant. The increased frequency (120 Hz) allows for smooth screen motion and very fast response times.

Maximum HDR brightness
Maximum HDR brightness

The HDR capabilities of the two OLED panels are also very good, as we measured a maximum brightness of 656 cd/m² for small image sections and more than 620 cd/m² on an almost completely white image. As is usual with Windows laptops, HDR has to be manually activated in the settings in order to display the corresponding content (e.g. videos) correctly. However, color management does not work correctly when HDR is active. Microsoft urgently needs to make improvements here and follow the example of Apple, where additional brightness is easily provided by the display when the corresponding content is displayed.

Various profiles are available in the MyAsus software and we measured these using professional CalMAN software (X-Rite i1 Pro2). The Native profile is active by default, but the colors are somewhat oversaturated. This is not a major problem in everyday use, as colors actually appear somewhat stronger. However, if you prefer accurate colors, we recommend the Display P3 profile, as the colors here remain below the important deviation of 3.

Both the P3 and sRGB color spaces are completely covered and there is also a suitable sRGB profile that limits the color space accordingly. The colors here are also very accurate. Using our own calibration, we were able to improve the display of the grayscale, but this increased the color deviations, which is why we do not offer the profile for download here.

Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
       Response Time Black to White
0.76 ms ... rise ↗ and fall ↘ combined↗ 0.41 ms rise
↘ 0.35 ms fall
The screen shows very fast response rates in our tests and should be very well suited for fast-paced gaming.
In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 1 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (21.5 ms).
       Response Time 50% Grey to 80% Grey
0.77 ms ... rise ↗ and fall ↘ combined↗ 0.42 ms rise
↘ 0.35 ms fall
The screen shows very fast response rates in our tests and should be very well suited for fast-paced gaming.
In comparison, all tested devices range from 0.2 (minimum) to 636 (maximum) ms. » 1 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (33.7 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM detected 480 Hz ≤ 80 % brightness setting

The display backlight flickers at 480 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 80 % 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 17900 (minimum: 5 - maximum: 3846000) Hz was measured.

The OLED panel utilizes PWM at a frequency of 480 Hz when brightness is at 80% or less. But Asus also offers the so-called flicker-free OLED dimming setting in the MyAsus software.

Although the high contrast ratio helps outdoors, reflections on the glossy touchscreen remain a problem, especially on bright days. The viewing angle stability gives no cause for complaint. Although there is the typical OLED blue shimmer at wide angles, this is unlikely to be a problem in everyday use.

Performance - Core Ultra 9 and 32 GB RAM

Asus equips the Zenbook Duo with the new Meteor Lake chips from Intel (Core Ultra 5, 7 or 9) and the RAM is soldered, either with 16 or 32 GB. Dedicated GPUs are not on board the Zenbook Duo.

 
 

Testing conditions

As usual, Asus offers three energy profiles (Standard, Whisper, Performance) in the preinstalled MyAsus software, whereby Performance mode is only available in mains operation. We have listed the TDP values in the following table.

Energy profile TDP Cinebench R23 Multi Time Spy Graphics Max. fan volume
Performance 64/35 watts 15,923 points 3474 points 47.8 dB(A)
Standard 64/20 watts 12,688 points 3283 points 39.4 dB(A)
Whisper 28/18 watts 10,852 points 2866 points 30.7 dB(A)

We carried out the following benchmarks and measurements in Standard mode. If you need maximum CPU performance, Performance mode is worthwhile, but you'll also have to deal with significantly louder ventilation.

Processor - Core Ultra 9 185H

The Core Ultra 9 185H is Intel's current flagship of the new Meteor Lake processor generation and thus the most powerful H45 processor. With a TDP range of 28 to 115 watts, the Core Ultra 9 is by no means fully utilized in the case of the Zenbook Duo, as the short-term maximum consumption here is 64 watts, which then drops to 30 watts and later to 20 watts. Performance in the short benchmarks is very good, but drops massively under sustained load. The CPU performance is of course perfectly adequate for everyday tasks, but there is no improvement over the old Raptor Lake chips, as previously observed in our Meteor Lake analysis. Performance in battery mode remains constant. Further CPU benchmarks are available here.

We also looked at CPU performance under sustained load with the other two energy profiles. Compared to the normal Zenbook 14 OLED with a fan, the Zenbook Duo is able to extract more power from the Core Ultra 9 (64 -> 40 -> 35 watts) and Performance mode is definitely worthwhile for those who require maximum CPU performance. Performance in Whisper mode is naturally lower, but still sufficient for simple tasks and the performance drop is not as significant.

System performance

The results in the synthetic benchmarks are very good - the Zenbook Duo is a very responsive computer in practice. This is also the case when using the second screen, as one never gets the impression that the convertible is overtaxed here. No issues with the system popped up during testing.

Storage devices

The 2 TB version of the Western Digital SN740 is installed in our Zenbook Duo test device and 1.79 GB of this is free when starting the laptop for the first time. However, the benchmark results of the M.2 2280 SSD are mixed. Despite repeating the tests, the results remained the same. At least there was no drop in performance under sustained load. Further SSD benchmarks are available here.
