The Optoma 5863RK is an interactive 86" touchscreen display with 4K UHD resolution (3840 x 2160). Designed for classroom and hybrid teaching environments, it combines a large, bright panel with built-in collaboration tools and Android-based software. The display includes an 8-array microphone with up to 8 m pickup, integrated speakers and subwoofers, and Google EDLA certification for access to apps via the pre-installed Google Play Store.

Advantages

The 86" 4K touchscreen provides clear, high-resolution content suitable for large rooms while a brightness of 450 cd/m² supports varied lighting conditions. Android OS with an ARM Cortex A76 + A55 processor and 64 GB user memory enables responsive on-screen interaction and app usage. Built-in audio (two 18 W speakers and two 8 W subwoofers) and an 8-array microphone simplify setup by reducing the need for external peripherals. Collaboration features include a launchable Whiteboard with annotation tools, shape recognition (Magic Draw), pressure-sensitive pen input, and real-time multi-location working.

Use built-in connectivity (Wi‑Fi 6) to connect external devices or link remote participants for real-time collaboration. Adjust audio volume and microphone settings from the system menu for optimal room coverage.

Recommendations

For best performance in teaching and hybrid sessions, mount the display at eye level for seated or standing users using the 800 x 600 mm VESA pattern, ensure a stable Wi‑Fi 6 network for collaborative features, and place the display centrally so the 8-array microphone can capture voices up to 8 m reliably.
