Superb Picture Quality

Enjoy vivid, lifelike visuals with Ultra HD resolution, delivering four times the detail of Full HD. The IPS panel ensures a wide viewing angle and consistent clarity across the screen.

Slim, Space-Saving Design

The UR640S Series features a thinner build compared to LG’s conventional models (UT640S), making it easier to install while blending seamlessly into any environment. The subtle blue finish also enhances the décor of modern business spaces.

Powered by an upgraded SoC and web engine, LG webOS™ Smart Signage provides a smooth, intuitive interface (GUI). Users can multitask effortlessly and access signage features with greater convenience.

Built-in Content & Group Management

Easily manage playlists, scheduling, and display groups directly from the TV using a remote control, mouse, or mobile device—no PC required.

  • Cisco Compatibility: Allows smooth operation with Cisco video conferencing setups (via optional HDMI cable).

Easy Menu Setup for Different Industries

Frequently used menus are pre-organized by verticals such as Corporate, Government, Retail, and Meeting Rooms for quicker setup.

Real-Time Maintenance with LG ConnectedCare*

This optional cloud-based solution provides remote diagnostics, monitoring, and control to ensure stable operation of client displays.
*Availability varies by region and requires a separate purchase.

Wireless Access Point Functionality

The display can function as a virtual router, allowing mobile devices to connect directly through its built-in Wi-Fi access point.

Power & Energy Efficiency

With Display Power Management (DPM), the screen only turns on when a TV signal is detected, reducing unnecessary power usage.

Real-Time Engagement Features
