Laser technology
Optoma laser projectors use high 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 greater efficiency in maintaining constant brightness, superior colourimetry, instant on/off and an extraordinary lifespan of 30,000 hours.
The ZK551's Ultra HD 4K resolution delivers sharper, more lifelike images and richer colours, 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 onto the screen. That's four times more detail than Full HD and twice as much as competing technology, which delivers just 4.1 million pixels.
