Our picks for interactive displays

Interactive displays are no longer futuristic novelties as they have become essential tools in modern classrooms and meeting rooms across Bangladesh. However, these devices come at a very high cost with prices ranging from BDT 200,000 to over BDT 1,200,000. So, before you invest, consider these key factors:

Display size and resolution
Screens typically range from 65 inches to 75 inches. A larger panel makes it easier for everyone to see detailed content, while 4K resolution ensures crisp text and vivid imagery.

Touch technology and latency
Look for infrared or capacitive touch with multi-point support (10+ touch points) and sub-10 ms response times, so digital ink feels as natural as chalk on a board.

Operating system and compatibility
Android-based systems offer simplicity and access to countless apps; Windows-capable slots (OPS) let you run full desktop software. Ensure your choice supports both platforms if your institution relies on specialised Windows programmes.

Connectivity and BYOM
Wi-Fi 6, Bluetooth 5.0, multiple USB and HDMI ports, and RJ45 Ethernet are must-haves. A true BYOM (bring your own meeting) feature lets participants cast from their own devices without installing extra software.

Audio and video
Integrated AI-powered cameras (4K with auto-framing) and microphones (beamforming, 8–12 m pickup) transform hybrid sessions, while built-in speakers or subwoofers deliver clear, room-filling sound.

With these criteria in mind, here are our top three interactive panels in the local market. Prices and availability may vary by vendor.
