The WP400 webOS box operates webOS 4.0, the enhanced user-friendly LG smart signage platform, and is attached to existing LG digital signages and upgrades them regardless of their original platform. It can execute several tasks at once while providing smooth content playback, and provides an excellent user experience.

The WP400 may be applied towards any type of LG digital signages regardless of its platform. The webOS box provides user-friendly smart functions with dedicated menus essential for business use. This way, users are able to easily manage and distribute content or develop web-based applications for multiple signages simultaneously.

The WP400 supports Ultra HD high-quality video playback which delivers true-to-life color details, with four times higher definition than FHD. Only a single webOS box is required for this superior picture quality.

Beyond content management, control commands from the WP400 can be sent to LG digital signages through the RS232C cable connection. It allows users to flexibly set up display values such as power, brightness or volume for optimal operation.

The WP400 offers a signage-dedicated home menu that shows key information related to signage operation at a glance. A dashboard showing the status of devices, a content management menu, and shortcuts leading to quick settings greatly enhance user convenience.

The embedded Content Management System (CMS) allows users to edit content using internal/external sources and set playlists to play at the desired schedule. Users can easily explore and manage content through the intuitive GUI, using various input devices, from a remote control to a laptop.

Several different videos can be played at the same time using the Multi-Video tags* feature. This gives you greater flexibility to organize and deploy content when various content items need to be delivered simultaneously via web apps.

Picture-By-Picture (PBP) features Multi-Screen in a single display with up to 4 input sources while Picture-In-Picture (PIP) supports playing both main screen and secondary screen at the same time with various layouts. This gives great flexibility to allocate space for each content source.

LG SuperSign is a comprehensive and indispensable software solution for the integrated management of LG digital signages. With SuperSign, content creation and distribution gets easier and centralized monitoring and control becomes simpler, helping your business save time and operate more effectively across different locations.

The maintenance gets easier and faster with an optional service Signage 365 Care, a cloud service solution provided by LG service. It remotely manages the status of displays in the client workplaces for fault diagnosis and remote-control services, assisting the stable operation of a client's business.
