A bigger window on your world
The narrow-bezel NanoEdge display features a frameless three-sided wide-view, with slim bezels that create an 84% screen-to-body ratio for incredibly immersive viewing experiences.

Next-level AI noise-canceling audio technology
With the increase of remote work and video conferences, we implemented the ASUS AI noise-canceling technology to ensure the best experience. The AI Noise-Canceling Mic feature in the MyASUS app effectively filters out unwanted ambient noise. There are two modes: Single-presenter mode allows the voice directly in front of the PC to be heard clearly; while Multi-presenter mode clarifies speech from different direction, ensuring optimum quality for group conference calls. The AI Noise-Canceling Speaker feature filters out all ambient noise apart from human speech — so you’ll hear what everyone else is saying.

ASUS ExpertBook B1 helps you minimize the hassles and inconveniences of remote work. With both Thunderbolt 4 and HDMI 2.0 ports available, you’re free to connect up to two external 4K UHD displays. So, for example, you could host a video conference on B1’s own display while using two screens on either side to keep in view information that’s important to your call. The screen is also certified by TÜV Rheinland for low blue-light emissions, proving a more comfortable viewing experience that potentially helps to protect your eyes from damage.
