ViewSonic PX748-4K for a Golf Simulator: Throw Distance & Mounting Guide
ViewSonic · 3840x2160 · 4000 lumens · Updated June 2026
The ViewSonic PX748-4K has a 1.13–1.47 throw ratio, which means it needs 16′ 1″ to 20′ 11″ 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′ 1″ – 18′ 4″ |
| 7.5 ft | 13.3 ft | 15′ 1″ – 19′ 7″ |
| 8 ft | 14.2 ft | 16′ 1″ – 20′ 11″ |
| 8.5 ft | 15.1 ft | 17′ 1″ – 22′ 3″ |
| 9 ft | 16.0 ft | 18′ 1″ – 23′ 6″ |
Ceiling mount & lens drop
With a 115% 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 a 8 ft screen would push the lens above the ceiling — lower the screen or use a model with lens shift. 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 26 ft of total room depth for the ViewSonic PX748-4K: maximum throw of 20′ 11″ 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 ViewSonic PX748-4K be from a golf simulator screen?
For an 8 ft tall 16:9 impact screen (14.2 ft wide), the ViewSonic PX748-4K's 1.13–1.47 throw ratio puts the lens 16′ 1″ to 20′ 11″ from the screen. Measure from the front of the lens, not the back of the chassis.
Is the ViewSonic PX748-4K good for a golf simulator?
ViewSonic PX748-4K is a standard throw 4k gaming model with 4000 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 ViewSonic PX748-4K?
Plan on roughly 26 ft minimum: 20′ 11″ 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.
