ViewSonic LDM136-151 136" Full HD All-in-One Direct-View LED Display

Product Overview

The ViewSonic LDM136-151 is a 136" all-in-one direct view LED display designed for conference rooms, boardrooms, and mid-size presentation spaces where a professional large-format display is required without the installation complexity of modular LED video walls. With a 1.56mm pixel pitch and native 1920 x 1080 Full HD resolution, it delivers crisp imagery at viewing distances starting at approximately 5 feet, making it the most pixel-dense model in the LDM series. The integrated all-in-one architecture eliminates the need for an external video wall processor, and the detachable control bar supports clean wall-mounted installations. Rated for 24/7 commercial operation, the LDM136-151 is suited for permanent deployments in conference centers, corporate headquarters, and educational institutions.

Product Description

The LDM136-151 measures 119.3" wide by 67.1" tall with a 31mm ultra-slim profile. Glue-on-Board (GOB) surface treatment encapsulates the LED array in a protective resin layer, providing IP54 dust and moisture resistance and improved surface durability relative to bare LED panels. The display runs Android 9.0 on a quad-core RK3399 processor with 4GB DDR4 RAM and 32GB internal storage, enabling standalone digital signage playback and app-based workflows without an attached PC. Built-in dual-band Wi-Fi and pre-installed vCast software support wireless content sharing from multiple devices simultaneously, including Picture-by-Picture from up to four sources and Picture-in-Picture for overlay content. AirPlay and Google Cast are natively supported. Crestron control, LAN IP control, RS-232 serial control, and ViewSonic Manager integration allow AV integrators and IT administrators to manage the display remotely within larger facility systems. Four HDMI 2.0 inputs with HDCP 2.2 handle any current-generation video source. Dual 30W integrated speakers deliver presentation audio to the room, with S/PDIF and 3.5mm audio outputs available for professional audio systems. Front hot-swap LED modules with the included vacuum suction tool enable field maintenance without rear wall access, reducing service time and labor cost.
