Two ASUS Zenbook DUO are placed on the table along with sleeve, charger and stylus.
  1. The model shown is for reference purposes only. Actual models may differ.
  1. Product and accessories specifications may differ from country to country. We recommend that you check with your local dealers for the specifications of the products available in your country.​↑
  2. The visual appearance of OLED displays may change over the product’s lifetime. This is expected behavior that can include image persistence or burn-in, where the display shows a faint remnant of an image even after a new image appears on the screen. This tends to occur only in extreme use cases, such as when a static, high-contrast image is continuously displayed for prolonged periods of time. ASUS laptops with an OLED display minimize this risk by setting Windows’s Dark mode as default, as well as shortening the idle time before the screen is turned off — both on mains (AC) and battery (DC) power. This dual approach minimizes the potential for burn-in to maximize the lifespan of your OLED display lifespan, and also reduces unnecessary power draw for optimal battery life. We also recommended adjust the brightness of your OLED display to complement the ambient lighting in your environment, rather than keeping the screen at maximum brightness at all times. You should also ensure that you have an animated, dark-background screensaver enabled in the Windows Settings tool.↑
  3. The availability and warranty for bundled accessories/stylus vary according to country and territory. Please check with your local ASUS retailer for details.↑
  4. Without keyboard.↑
  5. Weight might vary by specifications.↑
  6. Average tested result in MyASUS Splendid Display P3 and sRGB color gamut: Delta E < 1, +/- 0.5, and may vary by specification. Please note that the actual performance also may vary under different test procedures, equipment and patterns.↑
  7. Compared to average LCD displays in the market, measuring energy emission of blue light in between 415-455 nm wavelength.↑
  8. To further maximize the protection of your OLED laptop, ASUS has included OLED Care settings such as pixel refresh and pixel shifting, which are turned on by default. It’s important to note that if any burn-in issues do occur within the warranty period, which might vary by countries, ASUS offers a free exchange service for the affected OLED laptop as long as the user did not manually turn off the OLED Care functions.↑
  9. Testing done on discrete parts, using soda-lime glass as comparative reference. Figures and tests provided by Corning.↑
  10. The figures are based on theoretical performance. Actual performance may vary in real-world situations.↑
  11. Performance claim is based on the Cinebench R24 Multi Core benchmark, comparing the score of Zenbook DUO UX8406CA tested by ASUS in December 2024 (configured with Intel® Core Ultra 9 285H, 32 GB LPDDR5x RAM, a 2 TB PCIe 4.0 x4 SSD) and Zenbook DUO UX8406MA (with an Intel® Core Ultra 9 185H processor, 32 GB LPDDR5x RAM, and a 2 TB PCIe 4.0 x4 SSD). Test settings: select Performance mode under Fan profile in MyASUS, and idle the laptop for 10mins prior to running the benchmark under AC mode. It’s important to note that results may vary based on different specifications and testing environments. ↑
  12. Performance claim is based on the 3DMark Time Spy overall score, comparing the score of Zenbook DUO UX8406CA tested by ASUS in December 2024 (configured with Intel® Core Ultra 9 285H, 32 GB LPDDR5x RAM, a 2 TB PCIe 4.0 x4 SSD) and Zenbook DUO UX8406MA (with an Intel® Core Ultra 9 185H processor, 32 GB LPDDR5x RAM, and a 2 TB PCIe 4.0 x4 SSD). Test settings: select Performance mode under Fan profile in MyASUS, and idle the laptop for 10mins prior to running the benchmark under AC mode. It’s important to note that results may vary based on different specifications and testing environments. Note: Can be customized by models.↑
  13. This data is derived from ASUS laboratory testing, which involves simulating daily charging frequency as the testing standard. The actual lifespan of the battery may differ depending on factors such as product configuration, usage patterns, operational conditions, and power management settings. Over time, the battery’s longevity will naturally decrease. For more comprehensive information, please refer to the provided link.↑
  14. The Multi-Link Operation function, which allows the laptop to switch to the strongest Wi-Fi signal automatically, only works when the router is also Wi-Fi 7 compatible.↑
  15. The testing regime includes the requirements of both military-grade standards and ASUS quality tests, and varies depending on device. MIL-STD-810 testing is conducted on selected ASUS products only. Note that the MIL-STD-810 testing helps to ensure the quality of ASUS products but does not indicate a particular fitness for military use. The test is performed under laboratory conditions. Any damage caused by attempts to replicate these test conditions would be considered accidental, and would not be covered by the standard ASUS warranty. Additional coverage is available with ASUS Premium Care.↑
