LG 55TR3DK-B – 55-inch 4K Interactive Touchscreen Display

Product Overview

The LG 55TR3DK-B is a 55-inch 4K interactive touchscreen display built for collaborative meeting rooms, training spaces, and classrooms. As an all-in-one interactive flat panel, it combines 40-point IR multi-touch with an embedded Android system, so presenters annotate, browse, and share content without a connected host computer. The 3840 x 2160 IPS panel holds wide 178-degree viewing angles for group work, and a built-in OPS slot lets integrators add a Windows compute module for full PC functionality. This commercial touchscreen monitor fits both education and corporate deployment.

Product Description

The 55TR3DK-B (CreateBoard TR3DK-B series) serves as a writing surface, presentation screen, and conferencing endpoint in one commercial-grade chassis. Up to 40 simultaneous touch points support natural board writing and multi-user collaboration, while the 7H anti-glare surface withstands repeated stylus and finger input. ScreenShare Pro lets up to six participants mirror screens over the same network using AirPlay, Chromecast, or Miracast, supporting hybrid meetings alongside Bluetooth-connected peripherals. Air Class connects up to 30 student devices for interactive polling and response, which makes the panel a practical classroom collaboration display. For AV integrators and IT managers, the embedded Cortex A55 quad-core SoC with webOS, USB Block mode, Secured Mode, and RS-232C and RJ45 control simplify integration and fleet management. The product images included in this listing show the front-facing touchscreen, the port layout, and the bezel detail referenced throughout. ConnectedCare remote monitoring is available separately for fault diagnosis across deployed units.

Frequently Asked Questions

Does the 55TR3DK-B require an external PC to operate?
No. The panel runs an embedded Android-based SoC with webOS for annotation, browsing, and app use. For full Windows functionality, integrators can install an OPS compute module in the built-in slot.

How is the display mounted and installed?
The panel supports VESA wall mounting or a mobile cart in landscape orientation. The OPS slot sits at the rear, and port access is grouped on the front, side, and bottom for cable management in fixed installations.

How does it integrate with an existing AV and control system?
It provides RS-232C, dual Gigabit Ethernet, three HDMI inputs, and USB-C, so it connects to room control processors, codecs, and source switchers in a standard conference room or training room signal chain.

What wireless collaboration and conferencing is supported?
ScreenShare Pro mirrors up to six devices over the network through AirPlay, Chromecast, and Miracast, and Bluetooth 5.0 connects wireless peripherals for hybrid meetings.

What warranty and support options apply?
The display is backed by LG commercial warranty coverage, and optional ConnectedCare remote monitoring supports fault diagnosis across deployed units. Contact Creation Networks for current coverage terms and volume support.
