Optical range comes first
BenQ lists the AK700ST with a throw ratio of 0.69 to 0.83, a 1.2-times zoom and a native resolution of 3840 by 2160 in a 16:9 shape. These are model specifications, not a single mounting distance that will fit every enclosure.
Screen size and room geometry determine where that lens can sit. BenQ's own planning guidance calls for checking the projector against the golfer's swing space and the possibility of shadows, alongside the image dimensions.
The manufacturer's Auto Screen Fit instructions add a practical requirement: a black or similarly high-contrast border at least six centimeters, or 2.4 inches, around the screen. BenQ says the surrounding contrast helps its camera detect the edges, and recommends turning off ambient light during fitting.
Keep the creator's settings with his room
In the manual example, Friendly Golfer settles on a custom output of 3400 by 2160, then adjusts keystone and corners. That is his demonstration's setting. It uses fewer horizontal pixels than the projector's native 3840-by-2160 image.
The video separately shows Auto Screen Fit. BenQ describes that feature as identifying the screen and adjusting the image to standard shapes including 16:9, 16:10, 4:3 and 1:1. Its setup instructions call for the initial projection to extend beyond all four screen corners, followed by corner refinement and focus.
