Dahua LCH75 75-Inch 4K Interactive Whiteboard

LCH75 Smart Interactive Display

The Dahua 75-Inch Interactive Whiteboard combines a large-format DLED touch panel with an embedded Android 14 platform for classroom and conference collaboration. The 75-inch screen area supports multi-user annotation, wireless casting, and native app workflows without an external PC. Quad-core A55 processing with 8GB RAM handles simultaneous whiteboard layers and video conferencing apps.

2560 by 1440 resolution delivers sharp text and diagram clarity across the full canvas. Teachers and facilitators run education software, browser-based tools, and Dahua collaboration utilities directly on the panel. Sixty-four gigabytes of onboard ROM stores lesson files, screen captures, and cached media for offline sessions.

The display supports dual-mode operation across Android applications and external HDMI sources from laptops and document cameras. IT teams manage updates, network policies, and user accounts through standard Android enterprise controls. Wall-mount and mobile stand options fit lecture halls, huddle rooms, and training centers.

Capacitive or infrared touch layers respond to stylus and finger input for natural writing ergonomics. Built-in speakers and microphone arrays reduce peripheral clutter on teaching walls. Network connectivity over Wi-Fi and Ethernet enables cloud drive access and remote management dashboards.

Anti-glare coatings improve readability under fluorescent and window lighting in active classrooms. The MC410-B-S2 revision adds refined pen latency for handwriting recognition apps. Administrators push APK updates over the network to standardize software across campus deployments.
