UHD Commercial TV with Essential Smart Function

The UT640S series is specifically designed for diverse business environments. This commercial display TV provides compatibility with AV Control systems and Display Power Management (DPM) and it has smart connectivity, a simple user friendly interface, and UHD picture quality.

Embedded Content & Group Management

The embedded Content and Group Management System allows you to edit and play content, schedule playlists and groups. It also allows your business to control your signage via remote control, mouse and mobile phone without the use of separate PC or software, making content management much easier and more user-friendly.

SuperSign Control

SuperSign Control is the basic control software, and it can manage up to 100 displays through a single account and server. Power, volume, and scheduling can be remotely adjusted, and firmware updates supported.
*Displays need to be connected to the same network to be controlled by SuperSign.


  1. USB Data Cloning: USB data cloning increases efficiency in managing multiple displays for optimal operation since users don’t have to set up each display one by one. Once users copy data to a USB device in one display, it can be easily distributed to the other displays through a USB plug-in.
  2. Real-Time Remote Monitoring: Malfunctions or errors can be easily handled through real-time remote care. When an error occurs, notifications can be sent through the SNMP (Simple Network Management Protocol) protocol.
  3. Power On via the Network: Wake-on-LAN (WOL) enables users to turn on displays by sending messages through the network.

    True Color, Immersive View
    The UT640S series is large in size to enhance the visibility of content and captivate viewers. The LG IPS panel provides a wide range of viewing angles so that content can be clearly seen, regardless of the viewer's position. Each pixel in the IPS panel reproduces true-to-life colors without distorting images.


Perfect Picture Quality and Color
Enjoy Full HD content in 4K ULTRA HD quality, optimized by the 4K Upscaler. The 4K Upscaler automatically upgrades Full HD content to ULTRA HD through several upscaling processes so that images look crisp and clear in any viewing situation.


Compatibility with AV Control Systems: The UT640S series has been certified Crestron Connected®, proving that it has a higher level of compatibility with professional AV controls. This results in seamless integration and automated control*, boosting business management efficiency.
*It is a network based control system. Available AV control systems may differ by regions.

DPM (Display Power Management): From now on, you can configure the DPM (Display Power Management) function by setting it to On. When there is no signal, the TV enters DPM mode to manage power more efficiently.
