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.

Lights on viewing
The versatile Optoma ZK431st combines high brightness and vivid colours for vibrant, true-to-life visuals in any environment*. Make a lasting impression with bigger and bolder presentations any time of day.

Laser technology
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.
Reliable for Long-Term Use with DuraCore Laser
Optoma DuraCore Laser technology delivers consistent brightness, vivid colors, and up to 30,000 hours of lamp-free operation. With instant on/off functionality, reduced power consumption, and no lamp replacements, it offers a lower total cost of ownership and long-term, reliable performance—ideal for business and education environments.

Short Throw
