Product Overview

The LG 98UM5K-B is a 98-inch UHD 4K large-format commercial display on the LG webOS platform with built-in speakers and RS-232C control. Its IPS direct-LED panel delivers four times the detail of Full HD at a 500 cd/m2 brightness suited to indoor marketing. Built-in speakers carry audio without external hardware, and a slim profile allows close wall installation. The display supports Crestron Connected and LG SuperSign content management.

Product Description

The UM5K series pairs a 98-inch UHD panel with the webOS platform to deliver high-definition content in meeting rooms, airports, retail outlets, and shopping malls. At 500 cd/m2 the display shows content clearly under typical indoor lighting and is designed to capture public attention. Built-in speakers reproduce audio without the cost or installation of external speakers, and the slim chassis is intended for close wall mounting that improves the look of the installed space. The Promota app lets users build store profiles and customize content templates from PCs or mobile devices, while SuperSign provides integrated content management with options including SuperSign Cloud. Crestron Connected support enables integration with professional AV control systems for automated operation. The display offers portrait and landscape modes and connectivity through three HDMI inputs, one DisplayPort, and one DVI-D, with RS-232C for control.
