Bright, compact and easy-to-install Full HD projection
Designed for professional, educational and multipurpose spaces, the Optoma LH351 combines a Full HD resolution of 1920 x 1080 pixels, 3500-lumen brightness and a dynamic contrast ratio of 300 000:1. 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 LH351 also offers comprehensive connectivity, a 10 W speaker and multiple positioning options.
Durable 4LED technology for outstanding images
The DLP display technology and the 4LED source of the LH351 produce precise, bright and richly coloured images, with up to 1.0734 billion displayable shades. Its native Full HD resolution is equally suitable for detailed presentations and video content. The projector supports 4:3, 16:9 and 16:10 formats, while horizontal and vertical ±30° keystone correction makes image alignment easier. 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 LH351 can be monitored, scheduled and administered remotely to simplify the management of a fleet of devices, minimise interruptions and optimise operations. Its RJ45 connection and RS232 interface facilitate its integration into a centralised installation. Capable of operating 24/7 and projecting through 360°, including in portrait orientation, it adapts to numerous display scenarios. The Optoma Smart Control application also provides mobile-device control and image-correction functions via RJ45; the specification nevertheless states that its compatibility with Full HD models is still pending.
