Brilliant picture quality for professional demands
Experience a picture quality that presents your presentations and media content with outstanding clarity. Integrated 4LED technology ensures vibrant colours and exceeds the Rec.709 colour gamut, achieving excellent colour depth. Combined with a high light output of 3,500 lumens, the Optoma LH351 projects clear images that remain perfectly legible even in conference rooms that are not darkened. Native Full HD 1080p resolution ensures that fine details and text are reproduced pin-sharp, completely without compression. In addition, the projector supports HDR10 and Hybrid Log Gamma, making objects look more lifelike and creating an impressive sense of depth. Imagine presenting complex graphics in a sun-drenched meeting room while your colleagues can make out every detail with ease. This combination of brightness, high resolution and precise colour reproduction solves the problem of hard-to-see presentations in daylight, ensuring that your content always gets full attention.

Maximum flexibility for any room layout
Benefit from a range of installation options that adapt precisely to your specific room requirements. The compact housing of the Optoma LH351 allows discreet, easy placement in a wide variety of environments. 360-degree projection along the horizontal axis opens up entirely new scenarios for creative installations. This is complemented by portrait mode, which is ideal for digital signage applications or special corporate presentations. A 1.1x zoom provides additional flexibility for precisely aligning the image on the projection surface. If, for example, you are presenting in an architecturally demanding room, you can position the projector exactly so that it delivers the best possible image. This adaptability saves you costly alterations and gives you the freedom to realise your visual communication anywhere in the room. With these flexible placement options, you can easily master even demanding spatial challenges.
Intelligent management and absolute reliability
Rely on technical features designed specifically for continuous use and easy handling. With the Optoma Management Suite, you can manage and monitor the Optoma LH351 and other compatible devices conveniently and remotely in real time.

In addition, the Optoma Smart Control app allows direct control of key functions from your smartphone, so you can adjust picture settings without needing a PC. For demanding professional use, the unit is designed for continuous 24/7 operation, providing high reliability for day-to-day business. For corporate IT managers, this is a huge relief, as they can monitor the status of AV equipment centrally and provide fast support when needed. These intelligent management functions and robust design make the projector a dependable constant in your infrastructure.
