As usual, lets start at the front of the projector. Like the older BenQ projector, the PE7700 has a recessed lens, an infra red sensor for the remote, and below, two adjustable feet, both are screw thread, lacking the quick drop feet found on most projectors, but hardly an issue for a projector that isn't likely to get moved very often (if at all).
On the top are the recessed adjustments for the lens focus and zoom. The zoom ratio is 1.37:1, providing a lot more placement . flexibility than the PE8700 (1.2:1). I should also note that the BenQ PE7700 projector has a sealed light path, this has multiple benefits, primarily though, it prevents dust from getting into the projectors light path and ultimately causing colored blotches to appear on the screen. It also helps prevent annoying light leackage.
