Native 1080P Golf Simulation.
At The Entry Price.
You want a real BenQ projector for your first sim bay. Native 1080P, not upscaled. Short throw so the projector sits safely behind the golfer. 3,000 lumens of light that holds up with the room lights on. You're not paying for laser longevity or commercial features you won't use — you just want a clean, capable golf simulator setup at the lowest possible price. The BenQ TH671ST is the entry point into BenQ's golf projector lineup at $949 — a straightforward, well-engineered 1080P short throw projector for first-time builders and budget-conscious sim rooms.
Built by BenQ — the world's #1 projector brand for four years running, trusted in homes, boardrooms, classrooms, simulation bays, and commercial installations worldwide. Dedicated golf-simulator projector line since 2021.
Three Things The TH671ST 1080P Projector Gets Right At This Price.
What makes BenQ's lowest-priced golf simulator projector the right pick for first-time builders, budget-conscious buyers, and casual home sim rooms.
Native 1080P — Not Upscaled
True 1920×1080 Full HD resolution — every frame of simulator software rendered at full pixel count. No compression, no downscaling, no quality loss. Sharp clean images on a 100"–200" impact screen.
Short Throw — Out Of The Swing Path
0.69–0.83 throw ratio places the projector 9–13 feet from the screen, safely behind the golfer with no shadows in the swing zone. Mounts above and behind the hitting area cleanly.
3,000 Lumens In Lit Rooms
Bright enough for camera-tracking sim systems that need ambient light to read ball strikes. Holds up with lights on. LumiExpert auto-adjusts brightness as ambient conditions change.
You Probably Recognize Yourself In One Of These.
Three buyers we see for the TH671ST — entry price, 1080P resolution, and short throw matter for each.
You're Building Your First Sim Bay
First-time golf simulator builder
- You're new to home golf simulation and want a real projector — not a $299 budget toy
- You want native 1080P — no upscaling games or "4K-enhanced" marketing tricks
- You'd rather spend the budget difference on a launch monitor or screen
Why this fits: Real BenQ engineering, native 1080P, short throw, 3,000 lumens — the entry point that doesn't compromise on fundamentals.
Casual Sim Use, Not Daily
Weekend warrior, occasional sim user
- You'll use the projector 5–10 hours a week, not 30+
- Lamp life of 4,000–15,000 hours covers years of casual use
- You're fine with the occasional lamp replacement at $120–150 down the line
Why this fits: Lamp-based 1080P at $949 — lower upfront cost than LED ($1,499) or laser ($1,999+) models. Right tradeoff for casual sim use.
You Want Versatile 1080P For More Than Sim
Multi-purpose entry projector buyer
- Your sim room doubles as the family theater or game room
- You want 1080P that works for sports, movies, and console gaming
- You want short throw — not a long-throw projector across the room
Why this fits: Native 1080P + 16.7ms input lag + 3,000 lumens + short throw + dual HDMI — multi-purpose entry projector for sim, cinema, and gaming.

What You're Actually Getting.
Native 1080P + 16.7ms Input Lag
True 1920×1080 Full HD resolution — every frame of golf simulation software renders at full pixel count, with no upscaling or compression. Sharp, clean images on impact screens from 100" to 210". At 16.7ms input lag (1080p/60Hz), simulated ball flight appears on screen with no perceptible delay after each tracked shot — keeping the sim experience tight and responsive. The single-chip DLP from Texas Instruments delivers microsecond DMD response for clean motion handling.
Short Throw + Vertical Keystone — Easy Installation
The 0.69–0.83 short throw ratio places the projector 9–13 feet from the screen — safely behind the golfer, out of the swing path, with no shadows cast into the hitting zone. At those distances the projector fills screens from 177" to 210" without additional lenses or accessories. The 102.5% offset means the image rises naturally above the lens with minimal tilt, and vertical keystone correction ±40° compensates for trapezoid distortion from ceiling mount or angled positions. 1.2× optical zoom fine-tunes the image size after installation.
3,000 Lumens + 92% Rec.709 + LumiExpert
3,000 ANSI lumens of brightness holds up well in rooms with ambient light — important for camera-based golf simulator tracking systems that need ambient light to capture ball strike data accurately. 92% Rec.709 color coverage (the industry HD standard) renders course greens, sky blues, sand traps, and rough naturally. BenQ's LumiExpert technology automatically detects ambient light conditions and adjusts image brightness accordingly, keeping the image balanced and comfortable without manual adjustment as room lighting changes.
Lamp Modes — Up To 15,000 Hours In LampSave
The TH671ST uses a traditional lamp light source with four operating modes: Normal (4,000 hours), Eco and SmartEco (10,000 hours each), and LampSave (15,000 hours). Eco mode is the practical default for sim use — at 2 hours of daily simulation, 10,000 hours covers nearly 14 years. Replacement lamps are available from BenQ and most electronics retailers at $120–150 when eventually needed. Dual HDMI 1.4a inputs connect directly to your sim PC; one supports MHL for mobile device connection.

Picking between TH671ST, AH30ST, and AH500ST?
The TH671ST is the right choice if you want the lowest upfront cost and are comfortable with occasional lamp replacements over the projector's lifetime. The AH30ST ($1,499) is $550 more upfront but eliminates lamp replacements entirely (LED light source, 30,000 hours), adds Golf Mode color calibration, and steps up to 95% Rec.709 color and 2× higher native contrast. The AH500ST ($1,999) steps up to laser light source with ultra-short throw and 38,000-hour Eco life. Use the TH671ST for casual sim use or low total runtime; step up for daily use or maintenance-free reliability. Call (833) 796-4777 for help deciding.
