A bright, compact and easy-to-install Full HD projection
Designed for professional, educational and versatile spaces, the Optoma LH351ST combines Full HD 1,920 x 1,080 pixels resolution, 3,300 lumens of brightness and a dynamic contrast ratio of 300,000:1. Its short-throw lens makes it possible to achieve a large image from a short distance, making installation easier in a meeting room, classroom or confined space. Its 4LED light source, rated for 30,000 hours of use, eliminates the constraints associated with regularly replacing a lamp. Compact and designed for continuous operation, the LH351ST also offers comprehensive connectivity, a 10 W speaker and multiple positioning options.
Durable 4LED technology at the service of the image
The DLP display technology and the 4LED source of the LH351ST produce precise, bright and color-rich images, with up to 1.0734 billion displayable shades. Its native Full HD resolution is equally suited to detailed presentations and video content. The projector supports 4:3, 16:9 and 16:10 formats, while the horizontal and vertical keystone corrections of ±30° make it easier to align the image. Its relatively quiet operation, from 29 dB, also contributes to the comfort of meetings, classes and projection sessions
Smart management and remarkably flexible installation
Compatible with Optoma Management Suite (OMSC), the LH351ST can be monitored, scheduled and managed remotely to simplify device fleet management, reduce interruptions and optimize operations. Its RJ45 connection and RS232 interface make it easy to integrate into a centralized installation. Capable of operating 24/7 and projecting at 360°, including in portrait orientation, it adapts to many display scenarios. The Optoma Smart Control app is also designed to provide control and image correction functions from a mobile device via RJ45; however, the sheet notes that its compatibility with Full HD models is still pending.
