Editor's rating: 4 out of 5


This new design is also accompanied by a new cylindrical hinge that crosses the frame from side to side. The set is neat, but the midnight blue coating tends to highlight fingerprints.

Opening the hood reveals the 14-inch OLED panel framed by a thin edge.
The 3-level backlit keyboard offers comfortable and well-marked typing. The piano is stiff and the pumping effect is absent. The start button located at the top right of the keyboard has the same fingerprint reader as on the VivoBook Pro. Compatible with Windows Hello, it starts the PC or unlocks the session with a single touch of the index finger; The PC saves the fingerprint when the session is opened, so there is no need to rest your index finger on the fingerprint reader.

The large touchpad offers a smooth glide and takes good account of Windows movements. Our version is equipped with NumPad. If you press the upper right corner, a numeric keypad appears on top of the touchpad. The responsiveness is there and it is much more comfortable to use than the first versions released a few years ago.

The vast majority of connectors are located on the right side of the keyboard, with an HDMI 2.0 port, two Thunderbolt 4 ports, a mini-jack connector and a microSD card reader. A USB 3.2 port is located on the left side of the chassis between the hinge and the cooling system air outlet. An unbalanced distribution that can hinder right-handers, especially when all the ports are occupied.

Wireless connectivity is provided by the Intel AX211 chip, which supports WiFi 6E at 2400 Mb / s and Bluetooth 5.2. Finally, a poor quality 720p webcam is present above the Oled panel. It clearly lacks detail, whether in low light or in the brightest surroundings.

With good light.

In terms of cooling, Asus has completely changed its tune and returned to a side air outlet. With its new hinge, the air is no longer blown in front of the screen, but in a double opening in the left edge. Inside, a fan and heat pipe are activated to evacuate the calories released by the Alder Lake processor.

After 15 minutes of coding requiring all the cores in the processor, we noted almost 43 ° C at the level of the K, L and M keys. The Z, Q, S and D keys located above the fan remain perfectly fresh. Noise pollution in normal ventilation mode is 39 dB, which is reflected in an acceptable hum. If, on the other hand, you want to cool the processor better, it is possible to push the ventilation via the MyAsus software. In this case, the noise pollution rises to 44.5 dB and risks disturbing your office neighbors with a much more present noise, and without providing better performance.

Disassembly is performed by removing 6 Torx screws and 2 Phillips screws hidden under the non-slip pads. Once the screws have been removed, simply loosen the shell to access the inside of the ZenBook 14 Oled. The battery, SSD and wifi card are removable, but the RAM is soldered to the motherboard.

ZenBook 14 Oled (UX3402ZA) has an Intel Core i7-1260P processor accompanied by 16 GB DDR5 RAM and a 512 GB SSD Core i7-1260P is a hybrid processor consisting of 4 so-called “performance” hyperthreaded cores and 8 so-called “efficient” cores, all for a 28 W thermal envelope. During our test, the P cores ran at an average of 2.42 GHz, with peaks at 3.9 GHz, while the E cores ran at an average of 1.92 GHz, with a maximum of 2.71 GHz.

The ZenBook 14 Oled and its Core i7-1260P achieve an index of 108, placing it between the Ryzen 5 5600U from the HP Pavilion Aero 13 (95) and the Ryzen 7 5800U from the Acer Swift X (112). Core i7-1260P offers a significant gain over the previous generation with a 24% better index than Framework Laptops Core i7-1185G7.

A word about the SSD, which offers high speeds of 6.8 GB / s in read and 5.1 GB / s in writing. We did not notice any slowdown that could indicate a possible saturation of the cache during the transfer of our video rushes that were to put it to the test.

As the name suggests, Asus has equipped the ZenBook 14 Oled with a 14-inch Oled Samsung panel that displays 2880 x 1800 px at 90 Hz. The screen is therefore in 16/10. format, which promotes productivity even though Oled is perfect for multimedia use. The integration of the plate is neat. It occupies 82.6% thanks in part to its reduced lower limit.

The ZenBook 14 OLED panel shows its qualities during our analysis test. The Taiwanese manufacturer now seems to have mastered the Samsung panel perfectly. Thus, Delta E does not exceed 1.7, well below the threshold (3) for the human eye’s perception of colorimetric drifts. The color temperature (6537 K) is virtually fixed on the video standard (6500 K) and the contrast is almost infinite thanks to OLED technology. The blacks are therefore very deep and our probe is not able to measure them. The only drawback to this plate with a glossy finish, the anti-reflective treatment is absent subscribers. The average measured reflectance (reflected speed of light) is 51.3%. In comparison, the MacBook Air panel, also shiny, has a reflectivity of 26%. The brightness of 396 cd / m² will be sufficient indoors to counteract reflections, but too reasonable to work comfortably outdoors.


  • Well-calibrated Oled panel.

  • Plug included.

  • Core i7 performance.

  • Wi-Fi 6E ready.

Weak points

  • No anti-reflection treatment of the plate.

  • Mediocre webcam.

  • Connection distribution.

  • Soldered memory.

How does grading work?

The Asus ZenBook 14 Oled delivers an extremely compelling copy. Its processor delivers first-class performance, and what about this Oled panel, which borders on perfection; it only needed an anti-reflective filter that was worthy of the name. And to be really fussy, we were also able to point the finger at the questionable distribution of the connectors, without it tarnishing the excellent overall balance.
