Laser Technology
The Optoma laser projectors use premium-quality lasers to create an image. In most situations, the perceived brightness of laser projectors can be twice that of a traditional lamp-based model. They also offer better efficiency in maintaining constant brightness, superior color accuracy, instant on/off and an extraordinary lifespan of 30,000 hours.
The 4K Ultra HD resolution of the ZK451 delivers sharper, more realistic images and richer colors, allowing you to sit closer to the screen and enjoy a more immersive experience.
Optoma DLP projectors offer CTA (Consumer Technology Association) approved True 4K UHD resolution, capable of projecting 8.3 million pixels on the screen. That's four times more detail than Full HD and twice as much as competing technology, which delivers only 4.1 million pixels.
