LG WP402-B WebOS 4.0 UHD Digital Signage Media Player

The LG WP402-B is a commercial-grade digital signage media player designed to bring UHD content playback and centralized management to retail, hospitality, corporate, and public-facing display environments. Rather than requiring a smart signage display with built-in processing, the WP402-B functions as an external box that connects to compatible monitors and TVs, delivering 4K UHD output powered by LG's webOS 4.0 signage platform. This approach lets businesses upgrade their signage intelligence independently of their display hardware, which can be a cost-effective strategy when existing screens are still in good condition.

Running webOS 4.0, the WP402-B supports LG's signage content management ecosystem, enabling remote scheduling, content deployment, and display monitoring. The compact, lightweight form factor at approximately 3.9 pounds makes it straightforward to install out of sight behind a display or in a media closet. While the WP402-B targets commercial signage deployments rather than consumer use, businesses evaluating this player should verify compatibility with their existing displays and confirm that the webOS 4.0 feature set meets their content management requirements, as LG has since released newer versions of the platform with expanded capabilities.
