Each has its own price and specifications — pick one to open it.
The Huawei IdeaHub Board 3 Pro 75 (IHB2-75PB) is an intelligent collaboration device for meeting rooms, open discussion areas and training rooms. Its 75-inch 4K soft-light screen uses optical anti-blue light with zero color cast, and a 16 ms writing latency with AI handwriting tracking keeps writing and display in step — handwritten text and graphics convert to digital form, and content can be saved by scanning a QR code. Wi-Fi Direct projection starts 4K projection from a PC or mobile phone with no password or network connection: enable Wi-Fi on both and share. Cross-screen annotation lets you write over content, including into PowerPoint, and save it at any time. It runs HarmonyOS, and with an optional OPS computer installed it switches to Windows with one tap, no module swap needed. Huawei Cloud Meeting and WeLink are built in, and BYOM lets a laptop's own meeting app use the board. Password screen locking protects enterprise privacy and data. For IT teams, the IdeaManager platform manages and controls multiple IdeaHubs remotely, and IdeaCare runs one-click diagnostics of typical faults. Display: 4K (3840 × 2160), D-LED backlight, zero-gap bonding, infrared touch with a sensing distance of 1.5 mm or less. Audio: 4 speakers with 30 W total power (100 Hz to 20 kHz) and 6 microphones (100 Hz to 20 kHz) picking up sound across 180° up to 10 m away. Dual streams: 1080p30 + 1080p15, or 4K3. Auto-framing, intelligent tracking and an acoustic baffle are not included. Platform: 8-core CPU, 8 GB RAM, 64 GB flash, Wi-Fi 6 on 2.4 GHz and 5 GHz, and NFC.
