A webOS 4.0 player for LG signage

The LG WP400 is a media player box that runs webOS 4.0, LG's signage platform. It connects to LG digital signage displays and controls what they show, so organisations that already own LG screens can add managed playback without replacing the panel. In a new network, one player per screen keeps content, schedules and status checks in one place.

Playback, storage and display control

The WP400 plays Ultra HD video at four times the definition of Full HD. Its 8GB of internal memory provides 4GB for the system and 4GB available for content. The embedded content management system lets staff edit and play content and create playlists without a separate PC, with USB auto playback, local scheduling, gapless playback and content rotation. RS232C, RJ45 and IR inputs allow control commands that set power, brightness and volume on compatible LG displays.

Layouts for landscape and portrait screens

Picture-by-picture mode divides one screen into up to four sections, in landscape or portrait orientation, while picture-in-picture plays a main and a sub-screen at the same time. Tile mode supports video walls up to 15 by 15 tiles. A portrait panel in a hotel lobby in West Bay could show a welcome message beside the day's event schedule, and a row of displays in a control room can be arranged as one canvas.

Where it fits in Qatar

A hotel in West Bay can run a rotating welcome loop and event schedule in its lobby. A private school in Al Wakrah can update announcements in corridors and at reception from one pre-set schedule. A clinic in Al Sadd can show queue information and health messages in its waiting area. Shops in The Pearl can change promotional loops by time of day, and facilities teams managing several sites can apply the same schedule to each unit.

Planning the installation

The WP400 measures 258 × 36.5 × 186 mm and weighs 1.4 kg, so it can sit behind a display with room for cables. Its operating range is 0°C to 40°C at 10% to 80% humidity. Qatar summer temperatures can exceed 45°C, so place the player in an air-conditioned, ventilated space and confirm the environment with the SmartRooms Qatar team before ordering. It runs on 100 to 240 V, 50/60 Hz, drawing 16W typical and 22W maximum. The optional Signage 365 Care cloud service remotely checks display status for fault diagnosis. A free site survey helps confirm cable routes and control wiring before installation.

Questions about WP400

What is the LG WP400 and who is it for?

The LG WP400 is a small webOS 4.0 media player that controls what an LG digital signage display shows. It suits organisations that already run LG screens and want managed content without replacing the panel. It also suits new signage networks in Qatar, where one player per screen keeps schedules and content in one place.

Can the WP400 be added to existing LG digital signage displays?

Yes. The product is designed to attach to existing LG digital signage, which lets you upgrade the content platform of a screen you already own. Confirm the compatibility of your display model before ordering. The SmartRooms Qatar team can check it from your model number when you request a quote.

Does the WP400 play Ultra HD video?

Yes. It supports Ultra HD video playback at four times the definition of Full HD. Plan your video library against the 4GB of available internal storage, and prepare content at the resolution your target display supports.

Can a school in Al Wakrah update announcements without a PC?

Yes. The embedded content management system lets staff edit and play content and create playlists without a separate computer. USB auto playback, local scheduling and group management are included, so reception and corridor screens can be updated from one pre-set schedule.

Can a ministry reception in Msheireb switch its screen off after hours?

Yes. Power management includes on and off schedules, holiday schedules, Wake on LAN and power-on delay. The player can also send RS232C commands to set power, brightness and volume on compatible LG displays, which helps facilities teams match screen behaviour to a Sunday to Thursday working week.

Can a hotel lobby in West Bay show two messages on one screen?

Yes. Picture-by-picture mode divides a screen into up to four sections in landscape or portrait format, and picture-in-picture plays a main and a sub-screen at the same time. A portrait panel can show a welcome message beside the event schedule, and tile mode supports video walls up to 15 by 15 tiles.

Will it cope with summer heat and dust in a Doha reception area?

Only in a conditioned, ventilated space. The operating range is 0°C to 40°C at 10% to 80% humidity, while Qatar summer temperatures can exceed 45°C. Install it inside an air-conditioned room or a cabinet with airflow, keep it out of direct sunlight, and confirm the environment with the SmartRooms Qatar team before ordering.

What power does the WP400 need?

It has a built-in power supply rated 100 to 240 V, 50/60 Hz, which covers Qatar's 240 V mains supply. Typical consumption is 16W and maximum is 22W. A power cord is included. Add the player to your power plan when installing several screens.

Which software manages WP400 players?

The specification lists SuperSign CMS for content management and SuperSign Control and Control+ for control and monitoring. Across several sites, these tools let you publish content and monitor status from one central location. Specify the software you need in your quotation.

What is included in the box?

The package includes a remote controller, power cord, quick setup guide, HDMI cable, regulation book and a phone-to-RS232C gender adapter. Check the contents on delivery, especially the RS232C adapter if you plan to control displays over cable.

What is Signage 365 Care and is it included?

Signage 365 Care is an optional cloud service from LG that remotely monitors display status for fault diagnosis and remote services. It is not part of the standard accessories, so it must be specified separately in your quotation. It is useful for facilities with screens spread across several rooms or floors.

How much space do multiple WP400 units need for a purchase order?

The player measures 258 × 36.5 × 186 mm and weighs 1.4 kg. The carton is 314 × 124 × 359 mm and weighs 2.26 kg packed. Free site surveys are available before purchase, and one purchase order can cover several units for a school or government office across Qatar.
