LG XS4J Series 49" Class Full HD Digital Signage IPS LED Display (Black) - 49XS4J-B

Product Overview

The LG 49XS4J-B is a 49-inch Full HD window-facing digital signage display rated at 4,000 nits for high outdoor visibility. It uses an IPS LED panel with a Quarter Wave Plate (QWP) so content stays visible through polarized sunglasses. A quad-core SoC runs webOS 4.1 without a separate media player, and a smart brightness control adjusts output to ambient light. It is designed for storefront, window-facing placements.

Product Description

This high-brightness display targets window-facing retail placements where sunlight competes with the screen. At 4,000 nits it stays readable behind glass in bright conditions, and the QWP keeps content visible to viewers wearing polarized sunglasses. The IPS panel provides a wide viewing angle, and Full HD 1,920 x 1,080 resolution renders crisp content. The quad-core SoC running webOS 4.1 executes multiple tasks and plays content without a separate media player, while the platform offers an intuitive interface and simple app development tools. Smart brightness control raises output in bright conditions for visibility and lowers it in darkness for efficient power use. Ethernet, Wi-Fi, USB, HDMI, and DisplayPort connectivity support source input and networked management. The display is Energy Star certified.
