Combining crisp 4K image quality, built-in signage tools, and reliable commercial features, the PK340S Series delivers an efficient solution for businesses that need both TV broadcasting and digital signage functionality in one display.

4K UHD Display with HDR

The LG 55PK340S features Ultra HD 4K resolution for sharp visuals, detailed text, and enhanced clarity. HDR support improves contrast and color reproduction, ensuring more vibrant and lifelike content for promotional displays, presentations, and in-room entertainment.

270-Nit Bright LCD Panel

With a 270-nit brightness level, this commercial LCD panel is well suited for indoor environments, including retail stores, hotel common areas, offices, classrooms, and meeting rooms, providing consistent visibility and reliable performance.

webOS Smart Signage Platform

Powered by the LG webOS operating system, the 55PK340S offers smooth performance and built-in smart signage functionality. The intuitive interface allows for easy navigation, quick content updates, and simplified daily operation without external media players.

ATSC / Clear QAM Tuner

The integrated ATSC and Clear QAM tuner enables the display to function as both a commercial TV and a digital signage display, supporting broadcast content alongside custom signage—ideal for mixed-use hospitality and business applications.

  • Playlist creation and scheduling controls

  • Remote control, mouse, or mobile device operation

  • Simple group management for multi-display environments

For advanced deployments, the display supports LG SuperSign CMS (optional, sold separately).
