Asus ZenBook 14 UX434FL Laptop Review: ScreenPad Is Here To Stay

2 screens, 1 laptop. This Asus Ultrabook is unlike any other competing model in its size class due to its integrated secondary display. Though awesome from a conceptual standpoint, we go over some hidden drawbacks that potential owners should know about.

The Asus ZenBook 14 UX434 is an update to the older ZenBook 14 UX433 series with newer GPU options (GeForce MX250 vs. MX150) and the all-important integrated ScreenPad 2.0. As explained here, the ScreenPad is a clickpad-turned-touchscreen that essentially mimics an external display to aid in multi-tasking. The simple concept of having two screens on your laptop at all times is alluring for both productivity and multimedia reasons.

Aside from the ScreenPad and GeForce MX250 GPU, the ZenBook 14 UX434 is visually identical to the ZenBook 14 UX433. We recommend checking out our review on the UX433 series as many of our existing comments apply here on the UX434. The system competes directly with other upper mid-range 14-inch Ultrabooks like the Lenovo IdeaPad 5, LG Gram 14, Lenovo Yoga Slim 7, or the MSI Modern 14.

Case

The chassis makes no compromises for the integrated ScreenPad as it is the same as the ScreenPad-less UX433. The design is 13 percent smaller in footprint than the older UX430 chassis due to the narrower bezels. The ErgoLift hinges, however, could be stiffer.

The very narrow display bezels on all for sides (instead of just the left and right like on most other laptops) help the ZenBook 14 be smaller in footprint than many competitors. Weight and thickness are otherwise comparable despite the integrated ScreenPad functionality.

Connectivity

The UX434 integrates the same ports as found on the UX433. Keep in mind that the USB-C port does not support Thunderbolt 3 or even DisplayPort. Port positioning along the left edge is also tight and so thicker cables may block access to adjacent ports.

Maintenance

The bottom panel is annoying to remove since you will need two types of screwdrivers plus a spatula to remove the rubber feet covering the hidden screws. There is not much to upgrade once inside other than the M.2 2280 SSD because both RAM and WLAN are soldered.

Accessories and Warranty

Asus throws in a USB-A to RJ-45 adapter in addition to the usual AC adapter and paperwork. The standard one-year limited manufacturer warranty applies.

Input Devices

Touchpad

As a regular clickpad, the multi-touch ScreenPad surface is smooth with excellent gliding properties and only minimal sticking even when moving at slow speeds. It feels like a traditional clickpad instead of a tablet touchscreen since the overlay is matte and not glossy. The integrated mouse buttons, however, are unfortunately shallow and with weak feedback.

ScreenPad

On paper, the 5.65-inch IPS touchscreen and its 2160 x 1080 native resolution, high contrast ratio, and ~90 percent color coverage sound as good as any popular Android smartphone. In practice, however, the screen will be grainier than anticipated due to the matte overlay. Reducing the resolution will hide some of the graininess, but there's no doubt that this matte overlay impacts visual quality by a noticeable degree.

Analyzing the ScreenPad with an X-Rite colorimeter reveals a backlight that's even brighter than the main display which is good because the user will almost always be looking at the ScreenPad from a wider angle than the main display. Colors are not that well calibrated and grayscale is overly cool, but it is possible to calibrate the ScreenPad to address these shortcomings. Colors and grayscale would improve noticeably after calibrating the display ourselves as shown by our screenshots below.

ScreenPad 2.0 is a significant step forward when compared to the original ScreenPad on the old ZenBook Pro 15 UX580 in terms of picture quality and usability. It's still not quite as crisp as we would like, but the differences are noticeable. An external mouse is still recommended or else precision inputs on the small display will be difficult.

HWiNFO reveals Toshiba to the original manufacturer of the ScreenPad with the panel name ScreenXpert.

Display

The UX434 uses the same AU Optronics B140HAN03.2 IPS panel as found on the 2018 UX433 series meaning there are no changes to the display. This is great since the B140HAN03.2 is already a high quality display with good contrast ratio and color reproduction, but it's also disappointing at the same time because there are no new display options to choose from.

The Acer Spin 7 SP714 uses the same AU Optronics B140HAN03.2 panel as our Asus.

The display is poorly calibrated out of the box with its overly cool color temperature. After calibrating the panel ourselves, grayscale and colors would improve noticeably from average DeltaE values of 6.2 and 4.47 to just 2.1 and 2.89, respectively. We recommend calibrating the display to get the most out of its wide sRGB coverage.

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
28.8 ms ... rise ↗ and fall ↘ combined↗ 18 ms rise
↘ 10.8 ms fall
The screen shows relatively slow response rates in our tests and may be too slow for gamers.
In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 72 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (21.6 ms).
       Response Time 50% Grey to 80% Grey
37.6 ms ... rise ↗ and fall ↘ combined↗ 19.6 ms rise

The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.2 (minimum) to 636 (maximum) ms. » 48 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (33.9 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 not detected

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 18110 (minimum: 5 - maximum: 3846000) Hz was measured.

Outdoor visibility is average for the category and glare is ever present due to the glossy overlay. The MacBook Pro, HP EliteBook, and Dell XPS series have much brighter panels if outdoor visibility is a concern.

Performance

Though Asus offers 8th gen Core i5-8265U and Core i7-8565U options on this particular model, the newer refresh models includes 10th gen Core i5-10210U and Core i7-10510U options instead. Even so, the year-over-year performance gap between 8th gen Whiskey Lake-U and 10th gen Comet Lake-U is minuscule and so users wouldn't be missing out on much by going with the 8th gen series.

Nvidia Optimus comes standard for automatic graphics switching. Unlike the VivoBook S14 and its 25 W GeForce MX250, however, this ZenBook uses the much slower 10 W version with reduced clock rates across the board. AMD versions of the ZenBook 14 are also available albeit none come equipped with the ScreenPad feature as of this writing.

All benchmarks below were performed on High Performance mode for the best possible scores. We elected to enable the ScreenPad as well since this is a defining feature of the ZenBook 14 UX434 series.

 

Processor

CPU performance is good at about 10 to 15 percent faster than the average laptop in our database equipped with the same Core i7-8565U. It's within just a few percentage points of the newer Core i5-10210U or Core i7-10510U even though these latter processors are newer and often more expensive. Turbo Boost sustainability, however, is only average as performance can dip by as much as 20 percent when subjected to prolonged stress as shown by our CineBench R15 xT loop test results below.

See our dedicated page on the Core i7-8565U for more technical information and benchmark comparisons.

DPC Latency

LatencyMon shows DPC latency issues when opening multiple browser tabs on our homepage. Additionally, 4K UHD playback at 60 FPS is not smooth with 86 dropped frames and an unusually high CPU load of ~56 percent during our minute-long YouTube video test when the discrete GPU is active. Deactivating the discrete GPU fixes the playback problem although the DPC latency issues remain.

Storage Devices

The WD SN520 is an entry-level M.2 PCIe x2 NVMe SSD in contrast to the pricier PCIe x4 SN720 series. Theoretical sequential read and write rates top at 1700 MB/s and 1400 MB/s, respectively, which we're able to reach with CrystalDiskMark and DiskSpd. Though performance is more than sufficient considering the U-series CPU and GeForce MX GPU setup, higher-end Ultrabooks ship with the much faster Samsung PM981 series SSDs instead.

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

GPU Performance

Of the 25 different laptops in our database with the GeForce MX250, the one in this Asus is the slowest. 3DMark benchmarks reveal the GPU to be about 17 percent slower than the average MX250 which means it's slower than most older MX150 laptops. Even Asus' cheaper Asus VivoBook S14 S433FL is about to offer 30 percent faster graphics performance than our ZenBook with the same nominal MX250 GPU.

The disappointing graphics performance can be attributed to the 10 W TDP GPU whereas most other MX250 laptops are using the faster 25 W version. Boost clock rates top out at only 1038 MHz here compared to 1582 MHz on the MateBook 14.

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

System Noise

The single internal fan will idle when sitting on desktop, but it will quickly pick up in speed when running tasks like browsers or videos. Fan noise, for example, would slowly build up to its maximum of 41.5 dB(A) in less than 90 seconds when running 3DMark 06 to be louder than many other 14-inch Ultrabooks. The good news is that any RPM changes are steady and gradual and never too sudden.

We can notice no electronic noise or coil whine on our test unit.

Cooling solution is small as it consists of just a single ~50 mm fan and very short heat pipe for both the CPU and GPU

Temperature

Surface temperatures are cooler toward the front while the back can be as warm as 36 C simply by idling on desktop. Hot spots on the keyboard center and bottom can be as warm as 48 C to 53 C as shown by the temperature maps below to be similar to what we observed on the Lenovo Yoga Slim 7. You're going to want a desk if you plan on running games or other high loads on this machine.

Stress Test

When running Prime95 to stress the CPU, clock rates would boost to 3.3 to 3.4 GHz for about 30 to 40 seconds at a core temperature of 93 C. Thereafter, clock rates would drop and cycle between 2.1 GHz and 3 GHz and 69 C and 87 C, respectively, to keep temperatures at more comfortable levels. This cycling behavior is uncommon, but it can also be observed on the Dell XPS series.

When running Witcher 3 to represent more real-world stressful conditions, the CPU and GPU would stabilize at 75 C and 76 C, respectively, compared to just 58 C and 59 C on the faster Razer Blade Stealth.

Running on battery power will not impact performance. A 3DMark 11 test on batteries would return very similar Physics and Graphics scores as the same test on mains.

Energy Management

Power Consumption

Idling on desktop demands between 3 W and 7 W depending on display brightness and the current power profile. Activating the ScreenPad and setting it to maximum brightness will draw an additional 2.6 W.

Gaming will demand between 34 W and 47 W depending on frame rate and GPU stress. Overall consumption is less than both the Asus VivoBook S14 and MSI Modern 14 due largely to the lower-power 10 W GeForce MX250 in our Asus.

We're able to record a temporary maximum consumption of 62.8 W from the small (~6.3 x 6.3 x 3 cm) 65 W AC adapter when running Prime95 and FurMark loads.

Consumption when running 3DMark 06 is highest during the first 50 seconds before falling and stabilizing at ~44 W

Battery Life

Runtime is respectable at almost 7.5 hours of real-world WLAN use with the ScreenPad active. This is about an hour or two shorter than many other 14-inch subnotebooks including Asus' own VivoBook S14 which is the price ot pay for having a built-in secondary touchscreen.

Charging from empty to full capacity is fast at less than 90 minutes. The system cannot be recharged via USB-C.

As configured, our ZenBook 14 UX434FL currently retails for about $1400 to $1500 USD to be more expensive than other upper mid-range systems like the Lenovo Yoga Slim 7. Much of the price premium goes towards the unique ScreenPad as you're not going to find support for Thunderbolt 3, USB-C charging, DisplayPort, webcam shutter, or a fingerprint reader here. The slower 10 W GeForce MX250 GPU is also a bummer for casual gamers.

If you frequently find yourself in situations where a second monitor isn't possible, then the ScreenPad would be the next best solution. It can be invaluable for travelers and especially on flights where table space is limited. But for office or home users, it may be wiser to consider pairing the less expensive ScreenPad-less ZenBook 14 UX433 with an external monitor instead.

The ScreenPad is useful in situations where an external monitor is out of reach. ScreenPad 2.0 addresses many of the shortcomings of ScreenPad 1.0 for a smoother user experience and a slightly less grainy display. If you don't expect to use the feature all that much, then other subnotebooks are available with the same or better performance for less money.
