Product Overview

Overview

The LG 55UM3DG-B is a 55 Inch UHD Signage Display. The LG UM3DG series is UHD signage optimised for various indoor environments, delivering a resolution four times higher than Full HD with a wide IPS viewing angle and no distortion. It supports HEVC compression, playing ultra high quality video at half the network traffic of standard H.264, while Crestron Connected and Cisco System certification enable seamless AV control and smarter video conferencing. Its narrow bezel and slim depth save space and improve room decor, suiting corporate, retail, and meeting room installations.

Specification highlights for the 55UM3DG-B: Screen Size: 55 inch; Resolution: 3840 x 2160 (UHD); Brightness: 350 cd/m2 (typical). Corporate AV supplies and integrates the 55UM3DG-B across India for lobbies, retail and corporate signage projects, including site survey, installation and commissioning where the project needs it.

Key features

  • 55 inch UHD (3840 x 2160) IPS display, 350 nit brightness
  • HEVC video support, half the network traffic of H.264 for the same UHD quality
  • Cisco System certified for smarter, integrated video conferencing

  • Supports sensor connections (GPIO, NFC/RFID, temperature) via USB plug-in

Why choose the 55UM3DG-B
It is a 55-inch 4K UHD commercial display at 350 nits, so it holds up as screens that stay on in lobbies, retail areas and corporate spaces. Corporate AV checks the room, mounting surface, power and network during a site survey, so the 55UM3DG-B is installed and commissioned as part of a complete AV system rather than delivered as a box.
