Ultra short throw

With an ultra-short throw lens, you can project an impressive image greater than 100" from just 55cm away. This allows you to place the projector closer to the wall, reducing shadows so you can present with ease; perfect for interactive applications.


Amazing Colour

Optoma projectors are capable of reproducing the Rec.709 colour gamut, the international HDTV standard to guarantee accurate reproduction of cinematic colour exactly as the director intended. Optoma projectors can also create saturated colours, great for gaming and animated movies.

High Contrast

Add more depth to your image with a high contrast projector; with brighter whites and ultra-rich blacks, images come alive and text appears crisp and clear - ideal for business and education applications.

1080p (1920 x 1080) resolution renders sharp and detailed images from HD content without downscaling or compression, which is perfect for movies, TV shows and gaming.

Full 3D

Display true 3D content from almost any 3D source, including 3D Blu-ray Disc™ players, 3D broadcasting, and the latest-generation game consoles. Support for 144Hz rapid-refresh rate provides ultra-smooth flicker-free images. * requires optional Optoma 3D glasses
