These came from a local university when they upgraded their equipment. They've been tested and work 100% properly.  I have several of these, but they all look the same, so you will receive a projector that looks just like the one in the listing's pictures.  Includes standard lens, power supply, remote, and video cable. 



Bright, high-quality images with many advanced functions satisfy versatile applications. Along with operating noise of just 30 dB, the PT-DZ780 Series is perfect for noise-critical situations such as museums, exhibitions, and auditoriums. The PT-DZ780 Series features a digital zoom function that allows images to be enlarged up to 10 times (horizontally and vertically).
