ASUS Zenbook A14 (UX3407) review – Thin, Light, and Mighty
One of the most impressive things regarding the Zenbook A14 (UX3407) is its sub-1 kilo weight. Yep, that’s an ultra-light 14-inch Copilot+ PC that is powered by an eight or 12-core Snapdragon SoC. This also means that the upgradability is limited. Well, at least you can change the SSD drive with a bigger one. Because of the up to 45 NPU TOPS, this small fella is great for AI tasks, for those who need such functionality. Curiously, the Wi-Fi 7 connectivity is only available for the top-end X Elite CPU. The port selection is good for such a thin machine with its two USB4 connectors alongside a Type-A for better compatibility with different peripherals.
There are three display options. The base one for the X Plus-based iterations is a 1200p IPS screen. You can also pick a laptop with an OLED panel with the same resolution or a 2880×1800 120Hz beauty. The OLEDs also come with HDR capabilities.
The notebook may be thin but it has (perhaps) all you need for your day-to-day workflow like Dolby Atmos enhanced speakers, an IR Web camera for better security, a backlit keyboard, and a hefty (optional) 70Wh battery for longer autonomous work.

Drivers
All drivers and utilities for this notebook can be found here: https://www.asus.com/laptops/for-home/zenbook/asus-zenbook-a14-ux3407/helpdesk_knowledge/
What’s in the box?
The compact box houses the device itself and a bit of paperwork. You get a 65W or a 90W Type-C adapter depending on the CPU model. Some machines are bundled with an optional sleeve made of recycled polyester.
Design and construction
The design of the Zenbook A14 (UX3407) is clean and minimalistic. The device is made of Ceraluminum. Yes, that’s the end result when you combine ceramic and aluminum. ASUS claims that this material is anti-scratch and smudge-free. The latter is definitely true. After two days of usage, only a minimal amount of fingerprints are visible on the chassis. Well, we didn’t try to scratch the surface of the device, it looks too good for such a punishment.
During the opening, we got the feeling that the lid was featherweight. It opens incredibly easily with one hand (or even a finger). The unit feels averagely flexible which isn’t bad at all given how thin this thing is. Speaking of which, the profile thickness is just 13.4 – 15.9 mm. Depending on the SoC model and the display, the total weight varies from 0.90 kg to 0.98 kg. Overall, that is impressive! Last but not least, the base is solid.
The bezels that surround the OLED screen of our machine are nicely thin. The 1080p IR Web Camera for Windows Hello is placed on top. It sports 3D noise-reduction technology alongside an AI noise-cancelling microphone.
Let’s have a look at the backlit keyboard. It features large keycaps with moderate travel. Despite that, the unit feels suitable for typing since the feedback is clicky. According to ASUS, the keys have a smudge-free texture. It is but that type of layer isn’t the most grippy one. The mandatory AI shortcut is here, and yes – tiny Arrows. That’s a pretty common “feature” for the majority of the small laptops out there.
No complaints regarding the touchpad, it’s big, wide, smooth, and accurate.
Nothing unusual on the bottom plate – a ventilation grill, a pair of cutouts for the speakers, and two long rubber feet. The heat is guided through two vents on the rear. Because the hinge cover is positioned in front of them, relatively little hot air reaches the screen even during heavy CPU loads.
Ports
On the left, we can spot an HDMI 2.1 TMDS, two 40 Gbps USB4 ports that support DisplayPort and Power Delivery, and an Audio combo jack. On the right, there is just a single 10 Gbps USB Type-A 3.2 (Gen. 2) port.

Color Coverage
The whole “sail-shaped” map below (Fig. 1) consists of all the colors we can see, while the black crooked line shows all the colors from real-world scenes and nature around us.
Then, we’ve drawn some of the most important and interesting color spaces, compared to the colors the panel of ASUS Zenbook A14 (UX3407) can show:
Standard/For Web: sRGB – widely used color space for most consumer devices, ideal for Web design and development
For Print: AdobeRGB – used in professional photo editing, graphic design, and print
For Photographers/Video Editors: DCI-P3 – used in high-end film production, post-production, and digital cinema
Premium HDR: Rec.2020 – the widest consumer ITU color standard, covering a massive 75.8% of the visible spectrum, a benchmark for premium HDR content
ASUS Zenbook A14 (UX3407): the yellow dashed triangle (– – – – – –) represents the range of colors this monitor can display.+
In our tests, we calculated the total color coverage of the monitor at 100% of the sRGB color gamut and 100% of the DCI-P3 color gamut.
(Fig.1) ASUS Zenbook A14 (UX3407) covers 100% of the DCI-P3 gamut
The “MyASUS” app emulates Display P3 and sRGB color spaces.

Brightness and Contrast
The maximum brightness in HDR mode is 603 cd/m² at 8% white fill and 605 cd/m² on a full white screen.
The maximum brightness in SDR mode is 391 cd/m² in the center of the screen and 384 cd/m² averaged across the surface with a maximum deviation of 5%.
The Correlated Color Temperature (CCT) on a white screen at maximum brightness is 6440K (“Native-Default, Normal” mode in “MyASUS” app).
The contrast ratio of OLED panels is excellent because the pixels turn off completely when displaying black.
Uniformity: Luminance, Contrast, and Color Deviation
The figure below shows the results from our uniformity test across different sections of the screen. It’s measured at 179 nits (Windows slider = 71%) — a brightness level we consider typical for standard working conditions.
DeltaE values below 4.0 are acceptable for regular users. For those working with colors, screens with DeltaE values no higher than 2.0 are recommended.
Color Accuracy
Let’s check the difference between real colors and those you’ll see on the ASUS Zenbook A14 (UX3407). We measure that distance in DeltaE – the higher the number, the more different they look.
Values below 4.0 are acceptable for regular users, while values below 2.0 are suitable for color-sensitive work. A value below 1.0 means the difference is indistinguishable to the naked eye.
For the next graph, we’ve selected 24 common colors, including dark/light skin, blue sky, green grass, etc.
Below are the results of the ASUS Zenbook A14 (UX3407) in its factory condition (HDR off) compared to Display P3 and sRGB color spaces.

Visibility in dark scenes
Have you ever watched a movie with dark scenes where you could barely see anything? This often happens because many display panels struggle to differentiate the darkest nuances, making them appear the same.
The next figure illustrates how well the display reproduces these dark nuances. The left side of the image shows the display with stock settings, and the right side shows it with our Design and Gaming profile activated.
On the horizontal axis are the grayscale levels, and on the vertical axis – the corresponding display brightness.
You can also check how your display handles the darkest nuances but keep in mind that this also depends on the settings of your current display and the surrounding light conditions.
Health Impact: PWM (Screen flickering)
Some use PWM to regulate their brightness, which means that instead of reducing the light intensity, they pulse or flicker. Our brain merges the image, so it appears darker, but this strains both it and our vision, especially when the frequency of the pulses is low. You can read more about that in our dedicated article on PWM.
In the graph below, you see the intensity of light at different brightness levels—on the vertical axis is the brightness of the emitted light, and on the horizontal axis—time.
The light of the ASUS Zenbook A14 (UX3407) display is not pulse-width modulated, providing visual comfort in the discussed aspect.
Health Impact: Blue light emissions
Installing our Health-Guard profile reduces harmful Blue Light emissions while keeping the colors of the screen perceptually accurate.
If you’re not familiar with the Blue light, the TL;DR version is – emissions that negatively affect your eyes, skin, and your whole body. You can find more information about that in our dedicated article on Blue Light.
Health Impact: Screen Reflectance
Glossy-coated displays can cause eye fatigue in high ambient light conditions due to reflections. We measure the level of screen reflection with the display turned off, at a 60° angle.
The reflectance of the ASUS Zenbook A14 (UX3407)’s screen is 174 GU.
High Gloss: >70 GU
Medium Gloss: 30 – 70 GU
Low Gloss: <30 GU

Storage performance
Our notebook has a 1TB Micron 2500 (MTFDKBA1T0QGN-1BN1AABGA). It’s a fast drive that reaches 69°C during benchmarking.
Temperatures and comfort, Battery Life
Max CPU load
In this test we use 100% on the CPU cores, monitoring their frequencies and chip temperature. The first column shows a computer’s reaction to a short load (2-10 seconds), the second column simulates a serious task (between 15 and 30 seconds), and the third column is a good indicator of how good the laptop is for long loads such as video rendering.
Average core frequency; CPU temp.
| Qualcomm Snapdragon X Elite X1E-78-100 | 0:02 – 0:10 sec | 0:15 – 0:30 sec | 10:00 – 15:00 min |
|---|---|---|---|
| ASUS Zenbook A14 (UX3407) | 3.42 GHz @ 88°C | 3.11 GHz @ 92°C | 2.55 GHz @ 79°C |
The X Elite X1E-78-100 CPU maintains a 3.42 GHz / 3.11 GHz clock in short and medium loads which is a great result for a sub-1 kilo notebook. In long stress, the frequency is 2.55 GHz which is still a good result, especially for a small laptop.
Comfort during full load
The four fan modes can be found in the MyASUS app. You can also synchronize them with the default Windows power presets. The pair of fans doesn’t produce a ton of noise when the “Full-speed” preset is applied during long heavy loads. In this case, the keyboard doesn’t become scorching hot.
The “Standard mode” offers the almost same clock speed (~ 2.515 GHz) as the “Full-speed” preset (2.55 GHz). The fans are slightly more tamed if you choose the former.
Battery
Now, we conduct the battery tests with the Windows’ Power Efficiency setting turned on, screen brightness adjusted to 180 nits and all other programs turned off except for the one we are testing the notebook with. The 70Wh battery pack lasts for around 20 hours and a half of video playback. That’s a very good result considering the punchy CPU and the OLED screen. Оur test was conducted with the “Energy Saver” preset activated in the Windows “Power & Battery” menu and the “Standard” fan profile applied in the MyASUS app.
Brightness: 180 nits; Display Mode: SDR
Time to Full Discharge: Higher is Better
Disassembly, Upgrade options, and Maintenance
To see the internals of this compact Snapdragon-based laptop, you have to undo ten Torx-head screws. Insert a thin plastic tool in one of the top two edges to create a gap and pry the side. Do the same for the other side. Then, pry the front and pop the rear step by step starting from the zones close to the top corners. Raise the back of the plate and lift it away from the base.
The bottom plate houses a dust filter in front of each vent.
Our device has the bigger 70Wh battery because it’s configured with the most powerful Elite X1E-78-100 SoC for this ASUS series. For the not-so-punchy siblings, you can also pick one with a 48Wh capacity. To take it out, slide up the tiny metal cap on the top of the battery connector. Lift the sides of the connector and then raise the front. Wear gloves to avoid short circuits.
Then, undo the five Phillips-head screws that secure the battery in place. Four of which have rubber caps on top and you have to unglue them.
The capacity is enough for around 20 hours and a half of video playback.
The memory is soldered which isn’t a surprise since that’s a Copilot+ PC. The maximum possible amount of memory is 32GB LPDDR5X-8533 MHz in dual-channel mode which should be sufficient for normal home or office work. At least we can have a sneak peek at the RAM modules.
For storage, you get one M.2 slot compatible with 2280 Gen 4 SSDs. The NVMe drive isn’t additionally cooled by a thermal pad.
The Wi-Fi 7 card of our machine is placed on top of the mainboard.
The cooling seems more than enough for such a device. It comprises two fans, one long heat pipe, two heat sinks, and three heat spreaders different in size.
Verdict
We are impressed by the Zenbook A14 (UX3407). Its main tricks up in its sleeve are the low weight, the thin profile, and the overall performance that is ideal for home or office work. No matter the compact dimensions, the 12-core X Elite X1E-78-100 maintains 3.42 GHz in short loads and 2.55 GHz in long stress. Not bad at all given the 13.4 – 15.9 mm height of the laptop.
The 1200p OLED screen (ATNA40CT06-0 (SDC420D)) is great and even suitable for content creation or color-sensitive work. It boasts 100% sRGB and DCI-P3 coverage, an infinite contrast ratio, and almost 400 nits of max brightness in SDR mode. You can expect up to 603 nits when enjoying HDR content. The out-of-the-box color accuracy against the DCP-P3 color space is superb with an average dE result of just 0.9!
The battery life with the 70Wh unit is around 20 hours and a half of videos. In addition to that, the input devices are comfortable, the fans don’t sound too loud even during heavy CPU loads, and the performance is always there when you need it. When you add the super compact dimensions into the mix, this makes the Zenbook A14 (UX3407) a complete Copilot+ package.
You can check the prices and configurations in our Specs System: https://laptopmedia.com/series/asus-zenbook-a14-ux3407/
