Laser technology
Optoma laser projectors use high-quality lasers to create the projected image. In many situations the perceived brightness from laser illumination projectors can be twice that of an equivalent lamp-based model. They also deliver increased efficiency to maintain consistent brightness, superior colour performance, instant on/off and an extraordinary life span of up to 30,000 hours.

True 4K UHD resolution
Ultra HD 4K resolution delivers sharper, life-like images and richer colours - allowing you to sit closer to the screen and enjoy a more immersive experience.
Our DLP projectors provide CTA (Consumer Technology Association) approved True 4K UHD resolution, capable of projecting 8.3 million on screen pixels. That's four times more detail than Full HD and twice as many from competing technology, which only delivers 4.1 million pixels.

From accurate sRGB colours for lifelike images to vibrant punchy presentations. We have a display mode to specific meet your needs. Perfect for a range of graphic and video presentations.
