The PJ1158 utilizes advanced DLP technology, which enhances image quality by providing sharpness, saturation, and contrast. The DLP chip ensures that images are smooth and free from the pixelation that can occur with other projector types. Furthermore, the PJ1158 is equipped with a long-lasting lamp life of up to 15,000 hours, significantly reducing maintenance costs and downtime.
