Reasons why you need to choose the ASUS OLED laptop

Professional-grade true-to-life colors 

ASUS OLED laptops deliver exceptionally detailed and realistic visuals, with a cinema-grade 100% DCI-P3 color gamut.  

Colors reproduced on the display are richer and more vivid: it is ideal for color-intensive projects.

Blue light reduction

Blue light is known to cause visual discomfort and disrupt sleep quality. By calibrating the spectrum, ASUS OLED laptops emit 70% less harmful blue light. Unlike traditional blue-light filters, shifting the spectrum means color accuracy is uncompromised. 


Since children’s eyes are not fully developed, with a more transparent lens and cornea, harmful blue light can penetrate the eye more easily.

This means there is 80% blue light pass-through for 5 year-old children, compared to 20% pass-through for 60 year-old adults. 

Great clarity at low brightness 

When calculating the 3D color volume — which adds illumination to the traditional 2D color gamut — ASUS OLED displays have about a 60% higher color volume, offering better color performance at any brightness level. 

When comparing color expression under different brightness, OLED color expression stays the same ― even at lower brightness ― while LCD colors degrade significantly.  

Zenbook 14 OLED (UX3402ZA) Review

ASUS OLED laptops are able to show great detail at lower brightness settings. This means you can see the content more clearly without having to turn up the brightness; therefore, your eyes are exposed to less blue light. 

ASUS OLED laptops are able to maintain color detail at any brightness, so you can adapt the brightness according to your usage environment. Because OLED displays deliver accurate color with less brightness, eyes have less exposure to blue light. 

Extreme contrast, astonishing detail 

OLED displays have millions of light-emitting diodes (LED) instead of the just 50 or 60 LEDs found in LCD displays. OLED displays can turn on and off the LED for each pixel on the screen, and achieve true black with a 1,000,000:1 extreme contrast ratio.  

0.2 ms Instant response for smooth actions 

ASUS OLED displays have an ultrafast 0.2 ms response time ― 50X faster than average laptop LCD displays. This ensures smoother fast-paced action scenes, low-latency gameplay, and subtle details like blur-free text scrolling. 

ASUS OLED burn-in prevention  

With extended use, certain pixels on the display may age, resulting in degraded colors (burn-in). 

To prevent this, ASUS takes the following steps: 

  • Default shipping in Windows Dark mode 
  • Default OLED screen protection: Dims the screen after 5 minutes at idle    
  • Samsung OLED burn-in refine technology 
  • OLED screen warranty: 7000 hours, guaranteed (@200 nits) 

The Samsung OLED algorithm detects aging pixels and enhances the current passing through these pixels. This enables the degraded pixels to display brighter colors and, as a result, shows accurate perceived colors. 


ASUS OLED laptops come with an ASUS-exclusive OLED Care mechanism that’s proven to protect your OLED display. Image persistence, or burn-in, on an OLED display can occur if a static high-contrast image is displayed for a prolonged period of time.

To avoid this, when your ASUS laptop is idle for over 30 minutes, our specially designed screensaver kicks in. This significantly reduces the chance of burn-in by making sure all the pixels are illuminated and darkened equally, thus protecting the display from visible color shifts over time.

Impressive Specifications

With a thin and light form factor, the ASUS Zenbook 14 OLED series is equipped with the 12th Gen Intel® Core i7 P-series processor.

ASUS-exclusive WiFi Master Premium

The Zenbook 14 OLED series is equipped with ASUS WiFi Master Premium technology, which has a built-in dual‑band WiFi 6E wireless network for faster wireless transmission performance. It also has an ASUS-exclusive WiFi SmartConnect feature, which provides greater distance, stability, and seamless wireless network experiences for users.

The tri-band Wi-Fi 6E

Wi-Fi 6E adds a new 6 GHz band with up to seven additional 160 MHz channels while WiFi 6 devices share the same congested spectrum—and only two 160 MHz channels—with other legacy Wi-Fi 4, 5, and 6 devices. This gives WiFi 6E devices the advantage and ability to experience gigabit speeds more easily.

The tri-band WiFi 6E (802.11ax) wireless network card of the Zenbook 14 OLED series provides up to 3X higher throughput and 4X the network capacity of WiFi 5 (802.11ac), and it also supports Bluetooth 5.2 connection. Additionally, the WiFi 6E wireless network card is backward-compatible with legacy WiFi 6 and Wireless-AC. It will also work with legacy WiFi 4, 5 and 6 networks using 2.4/5 GHz bands.

WiFi SmartConnect

With WiFi SmartConnect, your laptop will automatically connect to the router with the best signal in your current environment. It also memorizes the mobile hotspots you connect to and prioritizes connections to them when they‘re detected.  

WiFi Stabilizer

In order to achieve extremely thin screen bezels, many laptops began to place the WiFi antennas under the keyboard area. However, this location houses many high-frequency hardware components, which can generate a lot of electromagnetic noise that interferes with WiFi signals.

To avoid this, the ASUS Zenbook 14 OLED series is equipped with noise reduction technologyto reduce USB 3.2 signal interference. It also has a metamaterial filterthat isolates electromagnetic noise radiating from the USB 3.2 ports. These features ensure that WiFi transmission performance remains stable and consistent.

USB-C Easy Charge for power anytime, anywhere

USB-C Easy Charge support means that the ASUS Zenbook 14 OLED series can be used with a wide range of standard USB-C chargers (5V-20V). Users can enjoy ultrafast charging with any PD (Power Delivery) certified charger, including the 65 watt fast-charge adapter supplied with the ASUS Zenbook 14 OLED series, or juice up your device on the go with airline chargers, portable chargers or power banks! It’s incredibly convenient when there are no wall sockets available, such as flights or in vehicles.

Easy USB-C® Charging ensures 4.5-watt charging when connecting to a non-Power Delivery chargers, including portable chargers or USB Type-A to USB-C® chargers. When using a Power Delivery charger, the charging speed will match the connected adapter’s power output, up to a maximum of 65 watts.

ErgoSense Keyboard

The ASUS Zenbook 14 OLED series features an ErgoLift hinge design which results in the ErgoSense keyboard automatically tilting when the laptop is opened. This design allows users to type more comfortably and increases the ventilation space under the chassis for improved heat dissipation.

ASUS Laptop

The keyboard of the Zenbook 14 OLED series achieves a 19.05 mm pitch (the distance between the middle of a key to the middle of its adjacent key) and offer many commonly used function keys, enabling users to type comfortably.

The keyboard is backlit for convenient typing in dark environments such as flights. In addition, the keys of ASUS Zenbook 14 OLED series feature a subtle 0.2 mm dish-shaped indentation and 1.4 mm key travel — the longest of its class of laptops.

The dish-shaped indentation subtly guides fingers onto the keys and the long key travel provides better feedback.

Together, these features improve typing accuracy and replicate the comfort of using a desktop PC keyboard.

Extra-useful hotkeys & Fn key with a lock option
