A conversion ratio applies for Xbox Game Pass Ultimate users. Limit: 1 per person/account.
- The devices referred to on this web page are the most highly-specified models available. Some models and configurations may not have an OLED display option. Please check the product specifications to ensure that the correct type of display is configured before purchasing in-store or online.
- The characteristics of an OLED display can eventually change over long periods of use, leading to visible changes. This is completely normal, and can cause behavior such as image burn-in or persistence: this means that a faint ghost of an image remains visible even when it’s replaced by a new image. These effects are more likely to occur if a non-moving (static) high-contrast image is displayed for an excessively long time. ASUS laptops with an OLED display minimize this risk by setting Windows 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 adjusting 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.
- By default, all models are set to a 60 Hz refresh rate. Users can increase this to the display’s maximum refresh rate manually via the display settings. For more information, please read the guidelines: http://www.stzgcm.com/support/FAQ/1013049/#Win11_A3.
- Average test results: Delta-E < 1.5, +/- 0.5. Over time, the Delta-E value of the display may change. It is recommended to recalibrate the color to ensure color accuracy.
- The figures are based on theoretical performance. Actual performance may vary in real-world situations.
- Battery durability and charging speed will vary depending on usage.
- Maximum SSD capacity may vary according to device configuration.
- Maximum RAM capacity may vary according to device configuration.
- Product weight may vary according to device configuration.
- Clinical testing using the ISO 22196 standard protocol proved that bacterial growth were inhibited by 99% over a 24-hour period. A 99% reduction in potentially harmful microorganisms is defined as the number of bacteria on the surface dropping from 1,000,000 (cfu/ml) to 100 (cfu/ml).
- Selected products are tested using enhanced military-grade MIL-STD-810H durability standards, with 12 test methods and 26 test procedures, to ensure extraordinary toughness. Based on ASUS internal market research using available information and testing reports from main laptop brand websites on Oct 28, 2022, ASUS consumer laptops use a regime consisting of 26 test procedures, which is the consumer laptop industry’s strictest and most extensive test regime for the MIL-STD-810H standard.
- Intel® Evo™ verification applies to certain configurations verified by Intel® Evo™ platform. For more details, please contact your local ASUS representatives.
- WiFi 6E availability may vary by country and their specific regulations. Feature only supported by Windows 11 or later.
- 802.11ax 2x2 160 MHz enables 2402 Mbps maximum theoretical data rate, ~3x faster than standard 802.11ac 2x2 80 MHz (867 Mbps) and nearly 6x faster than baseline 1x1ac (433 Mbps) Wi-Fi as documented in IEEE 802.11 wireless standard specifications, and require the use of similarly configured 802.11ax wireless network routers.
- This amendment defines standardized modifications to both the IEEE 802.11 physical layers (PHY) and the IEEE 802.11 Medium Access Control layer (MAC) that enable at least one mode of operation capable of supporting at least four times improvement in the average throughput per station (measured at the MAC data service access point) in a dense deployment scenario, while maintaining or improving the power efficiency per station. For additional details visit: http://mentor.ieee.org/802.11/dcn/14/11-14-0165-01-0hew-802-11-hew-sg-proposed-par.docx.
- “Up to 75% lower latency” is based on Intel simulation data of 802.11ax with and without OFDMA using 9 clients. Average latency without OFDM is 36 ms, with OFDMA average latency is reduced to 7.6 ms. Latency improvement requires that the AP and all clients support OFDMA.
- Performance claim is based on the Cinebench R23 Multi Core benchmark, comparing the score of Vivobook 16 X1605VA tested by ASUS in Nov 2022 (configured with an Intel Core i9-13900H CPU, 16 GB DDR4, and a 1 TB PCIe 3.0 SSD) to Vivobook 16 X1605VA tested by ASUS in Nov 2022 (with an Intel Core i7-13700H CPU, 12 GB DDR4, and a 512 GB PCIe 3.0 SSD), and Vivobook 16 X1605ZA (with an Intel Core i7-1255U CPU, 16 GB DDR4, and a 1 TB PCIe 3.0 SDD). Test settings: select Performance mode under Fan profile in MyASUS, and idle the laptop for 10mins prior to running the benchmark under AC mode.
- The component placement is for reference only, and may vary by model and configuration.
- Compared to an average LCD laptop panel. Average LCD display has a 10 ms response time.
- Compared to average LCD displays in the market, measuring energy emission of blue light in between 415-455 nm wavelength.
- The tabbed lid design will be black on Midnight Black and Cool Silver chassis, and will be orange on Solar Blue and Cream White chassis.
- ASUS Antimicrobial Guard is applied to the laptop areas that users touch most frequently, including keyboard, the palm rest area, the power button/fingerprint sensor and touchpad. A sticker on the laptop will help to identify the device is covered by Antimicrobial Guard due to different spec configuration.
- ASUS NumberPad 2.0 is an option that is only available on Midnight Black and Cool Silver. Please note that all versions of NumberPad 2.0 only work with the Microsoft Windows operating system.
- ISO 21702 specifies proper methods for measuring antiviral activity on plastics and other non-porous surfaces of antiviral-treated products. Test Viruses used in this International Standard are as follows: Influenza: An enveloped virus known to cause respiratory tract infection in humans. Feline calicivirus: A non-enveloped virus used in place of noroviruses known to cause enteric pathogens due to similar biological properties.
- ISO 22196:2011 specifies a method of evalsuating the antibacterial activity of antibacterial-treated plastics, and other non-porous, surfaces of products (including intermediate products).
- COVID-19, H3N2, H1N1, E. coli and Staphylococcus tests were performed by independent third-party laboratories: Boken Quality evalsuation Institute, Japan Textile Products Quality and Technology Center, and National Defense Medical Center.
- Antimicrobial treatments are manufactured by Co-Action Corporation.
- The Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) is the Federal statute that governs the registration, distribution, sale, and use of pesticides in the United States.
- The Biocidal Products Regulation (BPR, Regulation (EU) 528/2012) concerns the placing on the market and use of biocidal products, which are used to protect humans, animals, materials or articles against harmful organisms like pests or bacteria, by the action of the active substances contained in the biocidal product.
- Note that the protective effects of ASUS Antibacterial Guard were tested by ASUS on April 26, 2021, and follow the ISO 22196 method on our specially-treated test samples. The tests provide a simulation of three years of wear and tear, and include exposure to salt spray, thermal shocks, and both alcohol and wool-felt tests. Actual effective antibacterial-protection period may vary depending on product configuration and usage.

- The actual composition of ASUS Antimicrobial Guard Plus may vary.
- Fast Charging Technology is tested while the device is powered off with the default adapter included with the device. Charging time may vary +/- 10% due to system tolerance.
- 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.
- EPEAT registered where applicable. EPEAT registration varies by country. See www.epeat.net for registration status by country.
