BenQ X3100i for a Golf Simulator: Throw Distance & Mounting Guide
BenQ · 3840x2160 · 3300 lumens · LED · Updated June 2026
The BenQ X3100i has a 1.15–1.50 throw ratio, which means it needs 16′ 4″ to 21′ 4″ of distance to fill a standard 8-foot-tall 16:9 impact screen. As a standard-throw unit it mounts at or behind the hitting area, so confirm your head stays out of the beam before committing — the calculator below checks this automatically.
Throw distance by screen size
Lens-to-screen distance for common impact-screen heights (16:9 aspect).
| Screen height (16:9) | Image width | Lens-to-screen distance |
|---|---|---|
| 7 ft | 12.4 ft | 14′ 4″ – 18′ 8″ |
| 7.5 ft | 13.3 ft | 15′ 4″ – 20′ 0″ |
| 8 ft | 14.2 ft | 16′ 4″ – 21′ 4″ |
| 8.5 ft | 15.1 ft | 17′ 5″ – 22′ 8″ |
| 9 ft | 16.0 ft | 18′ 5″ – 24′ 0″ |
Ceiling mount & lens drop
With a 109% vertical offset, in a 9 ft room a 7.5 ft screen would push the lens above the ceiling — lower the screen or use a model with lens shift; in a 10 ft room with a 8 ft screen the lens sits about 3″ below the ceiling. Match your ceiling mount's drop length to that number — fixed 6″ drop mounts are often too long for high-offset short throws, which hangs the image below the screen.
Room depth check
Budget about 27 ft of total room depth for the BenQ X3100i: maximum throw of 21′ 4″ to an 8 ft screen, plus 10–12 ft of ball-to-screen distance and swing room. Behind-ball radar launch monitors add a further 7–9 ft behind the ball.
Frequently asked questions
How far should the BenQ X3100i be from a golf simulator screen?
For an 8 ft tall 16:9 impact screen (14.2 ft wide), the BenQ X3100i's 1.15–1.50 throw ratio puts the lens 16′ 4″ to 21′ 4″ from the screen. Measure from the front of the lens, not the back of the chassis.
Is the BenQ X3100i good for a golf simulator?
BenQ X3100i is a 4k gaming led model with 3300 lumens. Its standard throw needs a deeper room so the golfer stands behind the projector — check shadow clearance in the calculator.
What room depth do I need for the BenQ X3100i?
Plan on roughly 27 ft minimum: 21′ 4″ of throw to an 8 ft screen plus ball-flight and stance space. Radar launch monitors push the comfortable minimum higher — verify your exact layout in the free calculator.
