BELNET 55" 4K Smart Board — Android 11.0 with Optional Intel i5 Windows 10 Pro OPS, 20-Point Infrared Touch for Lecture Halls, Classroom and Office

This 55" interactive display pairs a 4K UHD panel (3840×2160) with a classroom- and meeting-ready feature set for lecture halls, classroom and office use. The screen delivers wide 178° viewing angles and a brightness range of 290-310cd/m² for clear visuals in varied lighting. Built-in Android 11.0 provides app and device control out of the box, while an optional Intel i5 OPS upgrade enables Windows 10 Pro with 4GB RAM + 256GB SSD for more demanding PC workflows. Interaction is handled by an infrared 20-Point Touch system with ±2mm precision and an 8ms response time, supporting natural handwriting, swiping and on-screen annotation. For presentations and media, HDMI/USB casting lets you plug in laptops, cameras or USB drives for instant, plug-and-play operation. The front surface is protected by a 7H-hardened glass panel and framed in aluminum to resist scratches and stand up to heavy use.
