LG 75TR3DK-B

The LG 75TR3DK-B CreateBoard is a 75-inch 4K UHD interactive display engineered for collaborative classrooms and modern meeting rooms. Built on an IPS panel with up to 40 points of simultaneous IR multi-touch input, it delivers a natural, responsive writing and drawing experience for groups of all sizes. Running Android 11 with a quad-core A55 processor, 4GB RAM, and 32GB storage, the CreateBoard operates as a standalone device with pre-installed whiteboarding, screen-sharing, and cloud connectivity software. An integrated OPS slot allows upgrading to a full Windows PC without any external box, while Wi-Fi 6 and Gigabit LAN ensure fast, stable network connections. With a 16-7 duty cycle rating and 50,000-hour panel lifetime, it is built for intensive daily use in demanding educational and corporate settings.

40-Point IR Multi-Touch Collaboration

The 75TR3DK-B supports up to 40 simultaneous touch points via infrared technology, with a touch response time of 5ms or less and positional accuracy of ±1mm. This means multiple students or meeting participants can write, draw, and interact on the board at exactly the same time without lag or false input. The protection glass (3mm, anti-glare) keeps the surface durable and readable, while the 25% haze treatment reduces reflections in brightly lit rooms. For classrooms, this translates directly into more engaging, participatory lessons where every student can have a hand on the board simultaneously.

Standalone Android 11 with Built-In Collaboration Software

Powered by a quad-core ARM Cortex-A55 SoC with Mali G52MP2 GPU, 4GB RAM, and 32GB storage running Android 11, the 75TR3DK-B works as a fully self-contained interactive board without any external media player or PC. Pre-installed software includes LG CreateBoard Share for real-time screen sharing of up to 9 devices simultaneously, whiteboarding with Note 2.0, LG CreateBoard Lab for lesson templates, and OfficeSuite for document editing. QR-code login makes session setup fast and keeps personal data secure. This keeps deployment simple and cost-effective — there is no need to budget for a separate PC just to run the board.

40 touch points. 4K IPS. One board for the whole class.

Integrated OPS Slot for Full Windows Capability

An integrated Open Pluggable Specification (OPS) slot lets installers add a Windows PC module directly inside the display chassis, eliminating any external box, cables, or desk clutter. This is especially relevant in environments that need Windows-native applications — such as specialist teaching software or enterprise collaboration tools — without compromising the clean, single-cable installation that schools and boardrooms demand. The OPS power supply is built-in to the display, so no separate power brick is needed for the module.

Wi-Fi 6, Bluetooth 5.0 and Gigabit LAN

The 75TR3DK-B ships with Wi-Fi 6 (802.11ax) via a slot-in module, Bluetooth 5.0, and a Gigabit LAN port — covering virtually every connectivity scenario. Wi-Fi 6 handles high-density environments such as classrooms where many devices are online simultaneously, reducing congestion and latency compared to older Wi-Fi standards. Wired Gigabit LAN ensures stable network management and Wake-on-LAN support. USB-C with Power Delivery (65W) and DP Alt mode allows a laptop user to connect, charge, and present over a single cable — a meaningful convenience in hot-desking and bring-your-own-device workflows.

Remote Management via LG ConnectedCare DMS

The 75TR3DK-B is compatible with LG ConnectedCare DMS (Device Management Software), enabling IT administrators to monitor, configure, and troubleshoot the display fleet remotely over the network. Threshold alerts can be set across eight categories — including display temperature, memory usage, and signal status — so issues can be caught before they impact a lesson or presentation. Remote fault diagnosis reduces the need for on-site service visits, which is a significant operational advantage for large school estates or multi-site corporate deployments.

16-7 Duty Cycle and 50,000-Hour Panel Lifetime

Rated for 16 hours a day, 7 days a week operation, the 75TR3DK-B is built for the continuous-use demands of schools and corporate environments — covering a full school day plus evening use without thermal stress. The IPS panel carries a 50,000-hour L30 lifetime rating, which at 16-7 duty translates to approximately 8.5 years of service before brightness drops to 70% of its original value. Smart Energy Saving and programmable on-off scheduling help manage power consumption across the school week. Security updates are supported for 5 years from the product launch date, providing a long, managed lifecycle.
