LG ProBeam BU53 for a Golf Simulator: Throw Distance & Mounting Guide
LG · 3840x2160 · 5000 lumens · Laser · 30 ms lag · Updated June 2026
The LG ProBeam BU53 has a 0.94–1.14 throw ratio, which means it needs 13′ 4″ to 16′ 3″ 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 | 11′ 8″ – 14′ 2″ |
| 7.5 ft | 13.3 ft | 12′ 6″ – 15′ 2″ |
| 8 ft | 14.2 ft | 13′ 4″ – 16′ 3″ |
| 8.5 ft | 15.1 ft | 14′ 2″ – 17′ 3″ |
| 9 ft | 16.0 ft | 15′ 0″ – 18′ 3″ |
Ceiling mount & lens drop
With a 100% vertical offset, in a 9 ft room with a 7.5 ft screen the lens sits about 6″ below the ceiling; in a 10 ft room with a 8 ft screen the lens sits about 12″ 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 22 ft of total room depth for the LG ProBeam BU53: maximum throw of 16′ 3″ 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 LG ProBeam BU53 be from a golf simulator screen?
For an 8 ft tall 16:9 impact screen (14.2 ft wide), the LG ProBeam BU53's 0.94–1.14 throw ratio puts the lens 13′ 4″ to 16′ 3″ from the screen. Measure from the front of the lens, not the back of the chassis.
Is the LG ProBeam BU53 good for a golf simulator?
LG ProBeam BU53 is a short throw 4k laser pro model with 5000 lumens and 30 ms input lag. 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 LG ProBeam BU53?
Plan on roughly 22 ft minimum: 16′ 3″ 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.
