Optoma HD806 - Physical Tour-3

HD806 Lens Throw

This Optoma has a 1.2:1 zoom lens, which is typical for DLP projectors. This provides limited placement flexibility. We expect most owners will ceiling mount the projector.

To fill a 100 inch diagonal, 16:9 aspect ratio screen, the HD806, as measured from the front of the lens, can be placed as close as 13.4 feet to the screen, as far back as 16.1 feet, or anywhere in between.

The limited placement range, and the lack of adjustable lens shift, preclude using the HD806 projector on a shelf in the back of a room, so typically, this projector will be ceiling mounted.

HD806 Lens Shift

The Optoma HD806 does not have adjustable lens shift. The projector's fixed shift places the projector below the screen when upright, or when inverted for ceiling mount, above the top of the screen.

For a 100 inch diagonal screen, that distance (above or below) is 17.6 inches. For larger or smaller screens you can compute the offset just by adjusting both numbers the same percentage.

HD806 Anamorphic Lens

According to the Optoma data sheet, the HD806 does support an anamorphic lens. The throw distances with an anamorphic lens are closest - 1.38x screen width, and 1.66x screen width for furthest placement. To get the correct aspect ratio for an anamorphic lens you would select the LetterBox aspect ratio.
