LG 55UR640S9UD – 55-inch UHD Signage TV

Product Overview

The LG 55UR640S9UD is a 55-inch UHD commercial signage TV built for always-on retail, hospitality, and corporate digital signage deployments. Running the webOS 6.0 smart signage platform on an integrated System on Chip, it plays 4K content directly from USB or LAN without an external media player, simplifying installation. A 400-nit IPS panel with wide viewing angles keeps menu boards, wayfinding, and conference room content legible across the room. Crestron Connected certification lets integrators fold the display into existing AV control systems.

Product Description

This UHD signage TV pairs a slim-depth chassis with a 3,840 x 2,160 resolution panel, making it a practical large-format display for flush wall mounting in lobbies, meeting spaces, and quick-service environments. The embedded Content and Group Management system lets staff schedule playlists and update messaging by remote control or mobile device, while LG SuperSign CMS supports centralized content creation and distribution across multiple displays. For commercial deployment at scale, the display supports SuperSign Control management of up to 100 screens from a single server, plus Wake on LAN, SNMP, and self-diagnostics for remote maintenance. Built-in Wi-Fi, Bluetooth Low Energy beacons, and screen mirroring extend its use into interactive retail signage and huddle-room presentation. The display also includes Failover and USB cloning to speed multi-unit rollouts. For larger rooms, compare the 65-inch UR640S signage TV and the 75-inch UR640S signage TV, or the compact 43-inch UR640S signage TV for smaller spaces.

The display uses a 300 x 300 mm VESA pattern and a 2.3-inch slim depth, suiting standard commercial flat or recessed wall mounts.

Can I manage multiple units remotely?
Yes. SuperSign Control manages up to 100 displays from one server, and Wake on LAN, SNMP, and self-diagnostics support remote fleet maintenance.
