Laser technology
Optoma laser projectors use high-quality lasers to create an image. In most situations, the perceived brightness from laser projectors can be twice that of a traditional lamp-based model. They also offer better efficiency in maintaining consistent brightness, superior color accuracy, instant on/off, and an exceptional lifespan of 30 000 hours.
1080p resolution gives you crisp, detailed images from HD content without downscaling or compression, perfect for watching Blu-ray, streaming HD video, and playing video games.
Quality colors
Create captivating presentations and lessons with vibrant colors. Optoma projectors provide reliable color performance suited to any content and environment: accurate sRGB colors for true-to-life images. A display mode is also available to meet every need. An ideal feature for projecting charts or videos.
Practical features
Thanks to numerous features, you can control and monitor the projector remotely. Optoma projectors come with a set of RS232 commands enabling easy, straightforward use with any control system. With Optoma Management Suite (OMS), you can also manage this projector and other compatible devices remotely. This cloud solution provides intuitive management, real-time monitoring and scheduling, helping to minimize downtime, improve performance, and reduce operating costs. This model is also compatible with Optoma’s SmartApp application, available on Android and iOS, which enables the use of various features without using a PC. Turn the device on and off, adjust the sound, change and configure display modes, then adjust the image remotely via your smartphone.
