Like The Apple Touch Bar, But Better: Asus ZenBook Duo UX481 Laptop Review

Two Screens, One Laptop. Asus wants to prove that there are other ways to innovate besides just creating the thinnest laptops year after year. The ScreenPad Plus display is both practical and invaluable when at its best, but it entails some ergonomic drawbacks.

In our review of the 15.6-inch ZenBook Pro Duo 15, we noted that its secondary ScreenPad display might work better on a 14-inch form factor because users would be more likely to travel with a 14-inch subnotebook than a full-size 15.6-inch model. Asus were apparently thinking the same — the 14-inch ZenBook Duo replaces the Core H-series CPU and GeForce GTX GPU as found on its larger sibling with more power-efficient Core U-series and GeForce MX parts. To put simply, the ZenBook Duo UX481 combines the looks and features of the high-end ZenBook Pro 15 with the processors of an affordable VivoBook S15.

The unit we are testing comes fully loaded with a Core i7-10510U Comet Lake-U CPU, GeForce MX250 GPU, 16 GB of LPDDR3 RAM, and a 1 TB Intel NVMe SSD for $1500. The 14-inch 1080p primary touchscreen and 12.6-inch secondary (1920 x 515) touchscreen come standard on all configurations. Retailers like Amazon and B&H are carrying this particular SKU. Lesser SKUs exist with the Core i5-10210U.

The ZenBook Duo has no equal in its 14-inch size category because of its unique ScreenPad feature, but we'll be comparing it to classic flagship Ultrabooks like the Microsoft Surface Laptop 3, Lenovo IdeaPad S940, Dell XPS 13, Huawei MateBook X Pro, and Asus' own ZenBook 14 to see what advantages and disadvantages the novel system brings to the table. HP offers laptops with second displays as well, but these only apply to gaming models at the moment.

Case

The chassis can best be described as a miniature ZenBook Pro Duo. Asus has shrunken the ginormous 15.6-inch version into a more manageable 14-inch size while retaining the solid build and impression of the original. The lid in particular is strong and more resistant to twisting and warping than the lids on many other subnotebooks like the Acer Aspire A514 or MSI Prestige 14. The base is also firm with no bending or creaking when applying moderate pressure likely because of its dense build and tightly packed components within.

Speaking of density, the drawbacks of having an integrated secondary screen become obvious when first picking up the system. At 1.8 kg and 19 mm thick, the system is roughly 500 g heavier and a few millimeters thicker than most ordinary 13.9-inch or 14-inch laptops like the Lenovo IdeaPad S940, Huawei MateBook X Pro, or Asus' own ZenBook 14. In fact, the ZenBook Duo is almost as heavy as the 15.6-inch Dell XPS 15 (1.9 kg) and so weight is definitely something to consider if you plan on traveling frequently with the dual-screen laptop.

Connectivity

All ports found on the larger 15.6-inch ZenBook Pro Duo are present here but with two important differences. First, the ZenBook Duo integrates a MicroSD reader while the larger version does not. Secondly, the USB Type-C port on the 14-inch model does not support Thunderbolt 3 much like on the ZenBook 14 clamshells. Port positioning is otherwise a non-issue.

SD Card Reader

The integrated spring-loaded MicroSD reader offers average transfer rates. Moving 1 GB worth of pictures from our UHS-II MicroSD card to desktop takes about 13 seconds compared to 7 seconds on the XPS 13 or 26 seconds on the ZenBook 14.

Maintenance

The bottom panel is secured by ten T5 Torx screws. Most of these screws are behind rubber inserts that are difficult to remove without a pair of very small tweezers. Once inside, users can only upgrade the single M.2 storage drive.

Accessories and Warranty

Asus includes an active stylus pen and a carrying sleeve in each retail box. The standard one-year limited warranty applies.

Input Devices

Keyboard

The backlit keys offer 1.4 mm of travel with crisp feedback and quiet clatter when pressed. We find the keyboard to be an improvement over the spongier keys of the older Zephyrus GX501. The upfront positioning of the keyboard, however, means users will have to sit further away from the laptop for a more comfortable typing experience and provide their own palm rests as well. It takes some getting used and it could be tricky if working in tight spaces like airplanes or even in trains with no tables at all.

Touchpad

Understandably, the touchpad got the short end of the stick since much of the surface area has been reserved for the keyboard and ScreenPad. At just 5.5 x 7 cm, it's way too cramped for any kind of serious workload. The smooth surface and dedicated mouse keys make accurate clicks a little bit easier, but you're going to want to use the touchscreen, included pen, or an external mouse whenever possible.

Display

The primary display is a Chi Mei N140HCE-EN2 IPS panel that can also be found on the MSI PS42MSI Modern 14, and Acer Swift 3 SF314. Thus, the ZenBook Duo doesn't offer many surprises here as these four systems share similar display features including the decent contrast ratio, decent response times, and full sRGB coverage. However, Asus has incorporated a matte touchscreen overlay that thickens the display a bit when compared to the aforementioned 14-inch models. Picture is slightly grainier than a glossy alternative as a result, but this is common on most matte panels.

Display brightness is not nearly as bright as most flagship Ultrabooks like the XPS 13, Surface Laptop 3, or IdeaPad S940. It'll be fine for indoor or classroom use, but there are better options out there if you plan on using the laptop outdoors frequently.

Because of the different viewing angles between the two displays and the user, attributes like glare, contrast, and colors will look different on the second screen relative to the main screen

Of course, the star of the show is the 12.6-inch secondary matte touchscreen that Asus has dubbed the ScreenPad Plus. It offers the same screen width and PPI as the primary display for a true 1:1 dual-screen experience. When viewing conditions are perfect, the ScreenPad becomes invaluable for multi-tasking, chatting, emailing, and most any other application because it behaves exactly like a second monitor on a desktop PC.

The biggest disadvantage of the second display is that the viewing angle between it and your eyes will almost always be wider than the viewing angle between you and the main display. Try looking at an IPS display from an obtuse angle and you'll notice that colors, contrast, and brightness may shift and the same can be said for the ScreenPad. Thus, onscreen content on the second display tends to be dimmer and not as vivid as the main screen. Combine this with its poorer color reproduction and more intense glare and you have a screen that works best for multimedia control and large texts rather than video playback or professional editing.

* ... smaller is better

Asus advertises 72 percent NTSC or full sRGB coverage for its ZenBook Duo laptop. The catch, however, is that this applies only to the main display. The secondary display covers only 59 percent and 38 percent of sRGB and AdobeRGB, respectively, compared to 100 percent and 63 percent on the main screen. Graphics editors should still be using the main screen for important workloads as colors will not be 1:1 between the two screens.

Asus advertises Pantone-certified calibration for its ZenBook Duo but, again, this applies only to the main screen. Our independent measurements with an X-Rite colorimeter do indeed show very accurate grayscale and colors on the main panel with average DeltaE values of just 2.2 and 0.93, respectively. In comparison, the average grayscale and color DeltaE values on the second screen are higher at 3.4 and 4.38, respectively. Attempting to calibrate the second screen even further ourselves would not result in significant improvements due to the limited color space of the panel. This isn't to say that colors on the second screen are poor, but they are not as vibrant when compared to the main screen.

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
25.6 ms ... rise ↗ and fall ↘ combined↗ 14.8 ms rise

The screen shows relatively slow response rates in our tests and may be too slow for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 46 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (24.4 ms).

In comparison, all tested devices range from 0.8 (minimum) to 636 (maximum) ms. » 23 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (38.7 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 24750 Hz ≤ 29 % brightness setting

The display backlight flickers at 24750 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 29 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 24750 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 17531 (minimum: 5 - maximum: 2500000) Hz was measured.

Though small in screen size, the ZenBook Duo is not the best laptop to use outdoors on a frequent basis. The display backlight is not bright enough to overcome ambient and there is glare in spite of the matte overlay. This becomes worse on the ScreenPad due to its atypical viewing angle relative to the user. Our screenshots below show how both screens become washed out when outdoors.

Viewing angles on both displays are still excellent as one would expect from any IPS panel. However, wide viewing angles alone aren't enough to fend off glare.

Performance

The Core U-class CPU and GeForce MX GPU are common finds on both mid-range and high-end Ultrabooks in contrast to the Core H-series and GTX GPUs that target high-performance users. The ZenBook Duo currently maxes out at the quad-core Core i7-10510U with no Ice Lake or AMD options available.

Meanwhile, the GeForce MX250 in our Asus is the slower '1D52' version compared to the faster '1D13' version as found on the MSI Modern 14. Base GPU and memory clock rates are therefore slower at 937 MHz and 1502 MHz, respectively, compared to 1519 MHz and 1752 MHz on the MSI.

System RAM is soldered and not user-upgradeable. We recommend going for the 16 GB configurations if possible since this laptop is all about multi-tasking between its two screens.

 

Processor

CPU performance is excellent on the surface, but running stressful benchmarks repeatedly will reveal the poor performance sustainability of the laptop over time. As an example, running CineBench R15 Multi-Thread in a loop results in an initial high score of 767 points before falling and stabilizing at 539 points to represent a performance drop of almost 30 percent. In comparison, the Core i7 Ice Lake CPU in the 15-inch Surface Book 3 would drop by only 6 to 7 percent over time in the same loop test. This is explored further in our Stress Test section below.

See our dedicated page on the Core i7-10510U for more technical information and benchmark comparisons. The hexa-core Core i7-10710U, which would have boosted multi-thread performance by about 50 percent, is not an option here.

System Performance

PCMark benchmarks are where we expect them to be relative to other laptops equipped with the Core i7 CPU and GeForce MX250 GPU. The PCMark 10 Digital Content Creation score, however, is lower than average. This particular benchmark has never been very accurate when it comes to assessing GPU performance between different laptops.

We experienced no software or hardware issues during our time with the test unit. Keep in mind that there is a slight learning curve to using the second screen before it becomes second nature. The positioning of the screen makes it much more ergonomic to use than the original ScreenPad on the ZenBook Pro UX580.

DPC Latency

LatencyMon shows DPC latency issues when opening multiple browser tabs and running Prime95 in sequence. Fortunately, our 4K video playback test on YouTube reveals no dropped frames. The integrated Intel GPU can be observed doing all the heavy lifting during cideo playback.

Storage Devices

Understandably, there is just one M.2 2280 slot with no secondary options due to space constraints. Note that some SKUs may come with PCIe x2 SSDs instead of PCIe x4.

The 1 TB Intel 660p NVMe SSD in our test unit returns roughly half the sequential read and write rates of the pricier Samsung PM981 according to AS SSD benchmarks. This balances well with the U-class CPU and power-efficient GeForce MX GPU involved.

See our table of SSDs and HDDs for more benchmark comparisons.

GPU Performance

3DMark benchmarks show the GeForce MX250 in our Asus unit to be about 16 to 18 percent slower than the average MX250 in our database taken from 21 other laptops. Evidently, supporting two internal displays takes its toll on the GPU. Expect performance to be most similar to the ZenBook 14 UX433 equipped with the older 10 W GeForce MX150.

On the flip side, the second screen will come in handy for chat programs or videos when playing a game on the main screen. Just keep in mind that any user input on the second screen will shift the focus away from the main game and possibly minimize or crash the window.

See our dedicated page on the GeForce MX250 for more technical information and benchmark comparisons.
