BenQ TH671ST Golf Simulator Projector
$949.00
The TH671ST is a short-throw 1080p projector that sits close to the screen — roughly 6 to 7 feet away — and fills a standard simulator screen cleanly. It’s the most straightforward projector in our lineup. Mount it, aim it, plug it in, and you’re playing. No automated calibration, no extra setup steps. Connect your PC over HDMI and you’re done.
Works in rooms where you can control the lighting. Uses a replaceable lamp rather than laser — plan for lamp replacement every few years. Best fit for golfers who want a solid, no-fuss projector at an honest price.

What You're Getting
The TH671ST is BenQ’s entry point into golf simulator projection. It’s a short-throw lamp projector that mounts close to the screen, keeps cables tidy, and stays out of the swing zone. 1080p resolution fills a standard simulator screen clearly enough that you’ll read every fairway and green without squinting.
The difference between this and the laser models above it is the light source. The TH671ST uses a replaceable lamp — it’ll run for a few thousand hours before you need to swap it. If you’re building your first simulator and want to keep the upfront cost manageable, this is where most people start.

Installation — What to Know Before You Mount It
Measurement | Spec | Notes |
Throw ratio | 0.69:1 | Short-throw — projector sits close to the screen |
Distance for 120″ screen | Approx. 6–7 ft from screen | Measure your room before mounting |
Screen size range | Up to 120″ diagonal | Fits standard home simulator screens |
Keystone adjustment | Manual | You adjust it by hand during setup, not automatic |
Mounting | Ceiling or shelf | Standard projector mount works — not included |
ℹ️ Manual keystone means you’ll spend 10–15 minutes aligning the image when you first set it up. Not a dealbreaker — it’s a one-time task. But if you want the projector to align itself automatically, step up to the AH700ST or AK700ST.
ℹ️ The zoom range gives you some flexibility in exact placement, but distance still matters for image size. Not sure if this fits your room? Email [email protected] with your dimensions and we’ll confirm.
Connections
- 2 × HDMI — connect your PC to one, leave the other free
- USB — for power accessories

The Lamp vs Laser Question
The TH671ST uses a lamp, not a laser. Here’s what that means in plain terms:
| TH671ST (Lamp) | Laser models (AH700ST, TK710STi, AK700ST, LK936ST) | |
|---|---|---|
| Upfront cost | Lower — $949 | Higher — $2,199 to $4,899 |
| Light source life | 4,000–15,000 hrs depending on mode | 20,000+ hours |
| Replacement needed? | Yes — lamp replacement every few years | No — laser doesn’t need replacement |
| Brightness over time | Dims slowly as lamp ages | Stays consistent throughout lifespan |
| Best for | Budget-conscious builds or first-time setups | Long-term permanent installations |
💡 If you plan to use your simulator heavily — daily or near-daily — the lamp cost adds up over time. For occasional use, the TH671ST is excellent value. Use our Custom Recommendation form at portersgolf.com/request-a-custom-recommendation/ if you want help choosing.
