Designed for professionals, students, and everyday users, it has an ASUS Lumina OLED display, a new Intel Core Ultra processor, and comes with the latest refresh host of networking hardware. Its total value, battery life, display, performance, and design are all thoroughly examined in this review.
Design & Build
The ASUS Vivobook S 14 boasts a premium appearance and long-lasting durability thanks to its CNC-machined aluminum chassis. It’s perfect for people who are constantly on the go because it’s only 1.39 cm thick and weighs 1.3 kg. In addition to being US MIL-STD 810H military-grade standard certified to survive drops, the 180° hinge offers versatility for a variety of usage scenario and comes in Neutral Black and Mist Blue to accommodate a range of style choices. The rounded edges is smooth and seamlessly embodied to the case that is not just sleek, but easy to be held and carry with ease with a blend that suits any occasion, be it for work or leisure use.
The chiclet keyboard on the Vivobook S 14 provides a comfortable typing experience with 1.7mm key travel and keycaps that is sturdy along with Windows Dynamic Lighting for customizable Single Zone RGB backlighting thus eliminating any other external or ASUS software to control it. All this can be configured via Windows Settings. The large touchpad supports smart gestures with Windows Precision Driver, improving usability. A dedicated Windows Copilot AI key allows for quick access to AI-powered productivity features while the FN shortcut keys are well placed and easy to execute.
Display, Audio & Webcam
A prominent feature of this laptop is its 14-inch ASUS Lumina OLED screen, which boasts a resolution of 1920 x 1200 (WUXGA), a color accuracy of 100% DCI-P3, and a maximum brightness of 500 nits. In addition to offering additional vertical workspace for productivity, the 16:10 aspect ratio improves the viewing experience with Dolby Vision and VESA DisplayHDR™ 500 True Black certification. Low blue light emissions also lessen eye strain when using the device for extended periods of time. The display’s 60Hz refresh rate is a small drawback; if ASUS raises it even a little on the refresh rate, the OLED panel, which is incredibly vivid and works admirably even at first glance, will enhance the experience by making any video displayed even smoother.
Equipped with Harman Kardon-certified stereo speakers and Dolby Atmos support, the Vivobook S 14 offers an immersive audio experience with vast configuration and customization via Dolby Access App. The smart amplifier and ASUS Audio Booster enhance sound clarity. The FHD AI-powered IR webcam features Windows Studio Effects and AI-enhanced noise cancellation, ensuring high-quality video conferencing.
