Full HD 3,500 Lumens Projector

The Optoma LH351 is a Full HD 1080p 4LED projector designed for business presentations, education and everyday entertainment. Delivering 3,500 lumens of brightness and a 1920 × 1080 resolution, it produces clear text, detailed images and vibrant colours in meeting rooms, classrooms and other environments with ambient light. Its 16:9 widescreen format is well suited to presentations, videos and films, while support for screen sizes up to 300 inches allows content to be displayed on a much larger scale. The long-lasting LED light source provides consistent performance without the need for conventional lamp replacements.

Built for reliable, low-maintenance operation, the LH351 offers up to 30,000 hours of light-source life in Eco mode and supports continuous 24/7 use. Its 1.1x optical zoom and horizontal and vertical keystone correction of up to ±30° simplify installation and image alignment. Connectivity includes two HDMI 2.0 inputs, VGA, RS-232 and RJ45 network control, allowing integration with computers, media players and centralised management systems. A built-in 10W speaker provides convenient onboard audio, while Optoma Management Suite Cloud enables remote monitoring and control across compatible projector installations.

Highlights
  • Full HD 1080p resolution delivers sharp, detailed images for business presentations, classroom lessons, video content and home entertainment.
  • High brightness of 3,500 lumens helps keep projected images clear and easy to view in rooms with ambient light, reducing the need to completely darken the space.
  • Four-LED light-source technology operates without a conventional replacement lamp, reducing routine maintenance and supporting a lifespan of up to 30,000 hours in Eco mode.
  • A high contrast ratio of 300,000:1 helps distinguish bright highlights from darker image areas, improving perceived depth and detail in suitable content.
  • Input lag:
    • 33.7ms (4K/60Hz)?
    • 16.7ms (1080P/60Hz)?
    • 8.4ms (1080P/120Hz)
  • Dynamic Black technology adjusts light output to suit the image, helping improve contrast across scenes with different brightness levels.
  • The 1.1× manual optical zoom provides some flexibility when positioning the projector, while the standard-throw lens suits conventional meeting rooms, classrooms and entertainment spaces.
  • Horizontal and vertical keystone correction of ±30° helps correct trapezoidal distortion when the projector is positioned above, below or to one side of the screen.
  • Support for 360-degree installation allows projection from a wider range of mounting orientations, while compatibility with 3D formats expands its use with supported visual content.
  • Two HDMI 2.0 inputs and a VGA input accommodate modern digital sources as well as compatible legacy computers, with audio input and output connections for external sound equipment.
  • Network control through RJ-45 and RS-232 supports integration into managed AV environments, while Optoma Management Suite Cloud enables centralised monitoring. Password protection and a Kensington lock slot provide additional security, and 24/7 operation supports continuous-use installations.

An Immersive Golf Simulation Experience

Bring the golf course to life, create an immersive environment where every round feels closer to the real thing. Enjoy lifelike fairways, detailed greens and vivid course scenery that help you feel connected to the game, whether you're practising your swing, refining your short game or playing a virtual round with friends. The large projected LH351 image makes it easier to follow the action and appreciate the layout of each hole, while the short-throw design helps minimise shadows from players as they address the ball and swing. Ideal for dedicated home simulators and indoor golf facilities, it helps transform an ordinary room into an engaging golf space for year-round practice, friendly competition and entertainment whatever the weather outside.

Effortless Setup and Reliable, Long-Lasting LED Performance

The lamp-free 4LED illumination system provides up to 30,000 hours of operation in Eco mode, eliminating routine lamp replacement and helping reduce maintenance requirements. Consistent performance and lower ongoing servicing needs make it suitable for installations where the projector is used regularly or for extended periods.

HDR Compatible

HDR, or High Dynamic Range, is a display technology that enhances the contrast and color range of video content. It allows for brighter highlights, deeper blacks, and a wider spectrum of colors, making images appear more lifelike and immersive. Unlike older formats that use a limited range of brightness and color (known as SDR or Standard Dynamic Range), HDR preserves more detail in both the darkest and brightest parts of a scene.

Flexible Installation

The 1.1x manual zoom lens and throw ratio of 1.49–1.64 provide flexibility when positioning the projector relative to the screen. Horizontal and vertical keystone correction of up to ±30° helps compensate for angled placement, while 360-degree installation capability supports a wider range of mounting orientations.

Compatible with Optoma Management Suite (OMS)

Optoma Management Suite (OMS) is an intuitive display management solution, designed to streamline operations by monitoring, diagnosing and controlling audio visual displays via a local area network from a single platform and location. Users can also broadcast or schedule alerts and messages across displays and remotely program and schedule device operating hours, reducing energy consumption and lowering operating costs.

Connectivity and Control

Dual HDMI 2.0 inputs accommodate modern video sources, while VGA supports compatible computers and legacy equipment. An RJ-45 network connection and RS-232 interface provide integration with control systems, and Optoma Management Suite Cloud enables centralised monitoring and management of compatible projectors.

Integrated Audio

The built-in 10-watt speaker provides convenient sound for presentations, instructional videos and general media playback without requiring a separate audio system. A 3.5mm audio output allows external speakers to be connected when greater volume or fuller sound is required.

Quiet and Convenient Operation

Eco operation reduces both power consumption and fan noise, with noise levels rated as low as 29dB. Password protection and a Kensington lock provide additional security, while support for 24/7 operation makes the projector suitable for installations requiring extended daily use.
