## Long description

The LG 55UM5N-H is a 55" digital signage flat panel with 4K Ultra HD (3840 x 2160) resolution and an IPS LCD panel. With 500 cd/m² brightness, anti-glare coating and a design for 24/7 operation, the display delivers clear, legible visuals in bright environments. The built-in webOS platform and high-performance SoC enable standalone operation without a separate media player, while integrated Wi‑Fi and SuperSign compatibility simplify content management and connectivity.
Advantages
The display offers four-times-FHD resolution for detailed imagery and an anti‑glare surface to reduce reflections. Its webOS platform and powerful SoC support multi‑tasking and easy integration with external sensors and partner apps. Durability features such as conformal coating on the power board, IP5x protection, 30° tilting capability and Shock Monitoring increase reliability in commercial settings. Design choices including thin bezels, hidden power inlets and slim brackets enable space-saving wall installation. Enhanced security measures—such as LG Enhanced Kernel Protection (EKP) and ISO/IEC 15408 Common Criteria EAL2 certification—protect data and system integrity.
Suitable for
Retail store displays and promotional screens
Corporate digital signage and reception areas
Transport hubs and public information boards

How to use

For standalone installations, deploy apps and media directly on the device using the built‑in SoC. Adjust tilt up to 30° as needed and enable Shock Monitoring and security features through the settings menu.
Usage recommendations
For optimal longevity and visibility, install the display in a location with controlled humidity and limited direct exposure to corrosive environments. Use anti‑glare settings and appropriate brightness levels for well‑lit areas, and manage content via SuperSign Cloud or local webOS apps to maintain consistent updates and security compliance.
