PowerLite Pro Z8250NL XGA 3LCD Projector

The projected image size can be from 60 to 500 inches (1.52 to 12.7 m).

Note:
The image size is measured diagonally and is determined by the distance the projector is placed from the screen, but can vary depending on the aspect ratio (image shape), how you zoom into the image, and whether you've adjusted other image settings. A utility to help calculate an image size or the projection distance is available from the Drivers & Downloads page for your projector.
