Well suited to premium golf simulator installations. The BU53RG combines 5,000 ANSI lumens of laser brightness with a 0.94–1.14 short-throw lens, helping reduce player shadows by allowing the projector to be mounted closer to the screen. With 4K UHD (3840×2160), lens shift (H ±20% / V ±50%) and advanced multi-point warping, it offers flexible positioning for simulator rooms and ceiling installations.
For 4K golf simulation, pair it with a suitably powerful gaming PC. Performance will depend on your simulator software, resolution and graphics settings.
⭐ Why it’s great for simulators
- 5,000 ANSI lumens for strong brightness in many indoor simulator installations
- Short throw 0.94–1.14 helps reduce shadows from the golfer and club
- Lens shift & advanced warping for flexible ceiling mounting and image alignment
- 4K/60 input via HDMI for detailed simulator visuals
- 20,000-hour light source for low maintenance
📐 Simulator throw guide (by screen width, 16:9)
Throw distance ≈ 0.94–1.14 × screen width (measured from lens to screen plane).
| Screen width | Image height | Throw distance range |
|---|---|---|
| 244 cm | 137.2 cm | 229–278 cm |
| 274 cm | 154.1 cm | 258–312 cm |
| 305 cm | 171.6 cm | 287–348 cm |
| 366 cm | 205.9 cm | 344–417 cm |
…or by diagonal (16:9)
| Diagonal | Image width | Image height | Throw distance range |
|---|---|---|---|
| 100″ | 221.4 cm | 124.5 cm | 208–252 cm |
| 120″ | 265.7 cm | 149.4 cm | 250–303 cm |
| 144″ | 318.8 cm | 179.3 cm | 300–363 cm |
Mounting tip: The H ±20% / V ±50% lens shift provides additional flexibility when aligning the image in ceiling-mounted simulator installations. Use lens shift for positioning first, then use advanced warping only for fine geometric adjustment where required.

❓ FAQ
Is 5,000 lumens enough with lights on?
5,000 ANSI lumens provides strong brightness for many indoor simulator installations. Final image brightness depends on screen size, ambient lighting and the impact-screen material.
How do I avoid club/head shadows?
The 0.94–1.14 short-throw ratio allows the projector to sit closer to the screen than a standard-throw model, which can help reduce shadows. Final placement should be planned around the hitting position, ceiling height and screen dimensions.
Does it support 4K/60 from my PC?
Yes, the projector accepts 4K/60 input via HDMI 2.0. For golf simulation, PC requirements depend on the software, resolution and graphics settings you use.
