When choosing between the ASUS ZenBook Pro 14 Duo and the Lenovo ThinkBook 13x, consider that the ASUS offers a unique dual-screen setup that can boost productivity, especially for multitasking and creative tasks, but this also makes it heavier and possibly less battery-efficient. The Lenovo ThinkBook 13x, on the other hand, is likely to be more lightweight and portable, making it a better option for those who travel frequently or prefer a more traditional single-screen experience. The ThinkBook might also have a longer battery life due to having just one screen to power. If your work involves intensive tasks like 3D modeling, video editing, or engineering software, the additional screen real estate on the ASUS could be very beneficial, though for general use or if you prioritize portability and battery life, the Lenovo might be the better choice.

The big attraction is the laptop’s dual displays. They’re the best ones we’ve used in an Asus Zenbook Duo laptop to date with a spate of year-on-year improvements that make the visuals more striking and the cross-screen integration easier than ever before."
