How they differ in real use
Built from our projectors for golf simulators scoring, each product's published specifications, and verified owner feedback — not hands-on testing.
Both the BenQ TK710STi and the Optoma GT2000HDR made our Top 5 Projectors for Golf Simulators, at #1 (best overall) and #4 (best budget). The best all-around golf-sim projector you can actually buy on Amazon: true 4K resolution makes course textures visibly sharper on a 10-foot impact screen than any 1080p rival, input lag is the lowest here at 1080p (4.2 ms at 240Hz), and its 1.2x optical zoom is the only real mounting flexibility in the group. It edges the brighter Optoma GT2400HDR because resolution and placement flexibility matter for the life of the build, while its brightness deficit (about 2,478 ANSI measured by ProjectorCentral) is solvable with basic light control. The budget pick that keeps the specs that actually matter: a 30,000-hour laser, IP6X dust sealing, the same 0.496:1 short throw, and 8.6 ms gaming input lag — at the lowest price of any laser here. It ranks above the TH671ST because it's brighter (3,500 vs 3,000 lumens), faster, cheaper, and maintenance-free, but below the GT2100HDR because its 20% lower output needs a light-controlled room to look its best.
We score projectors for golf simulators on Image Brightness & Quality (30%), Input Lag (20%), Throw & Mounting Flexibility (20%), Reliability & Maintenance (15%) and Value (15%). On that basis the BenQ TK710STi totals 9.1 out of 10 and the Optoma GT2000HDR 8.7. The widest gap is Image Brightness & Quality, where the BenQ TK710STi scores 9.6 against 8.2 for the Optoma GT2000HDR — lumens on an impact screen, resolution, and color. Value also separates them: 9.3 for the Optoma GT2000HDR versus 8 for the BenQ TK710STi.
On paper, the specifications that actually differ: Resolution — 4K UHD (3840×2160) on the BenQ TK710STi versus 1080p Full HD (4K HDR input) on the Optoma GT2000HDR; Rated Brightness — 3,200 ANSI lumens on the BenQ TK710STi versus 3,500 lumens on the Optoma GT2000HDR; Throw Ratio — 0.69–0.83:1 (short throw) on the BenQ TK710STi versus 0.496:1 (fixed short throw) on the Optoma GT2000HDR; Lowest Input Lag — 4.2 ms (1080p/240Hz); 16.7 ms (4K/60Hz) on the BenQ TK710STi versus 8.6 ms (1080p/120Hz) on the Optoma GT2000HDR; Light Source — Laser (LED-free DLP) on the BenQ TK710STi versus DuraCore laser on the Optoma GT2000HDR; Light Source Life — 20,000 hours on the BenQ TK710STi versus 30,000 hours on the Optoma GT2000HDR.
Pricing as of July 18, 2026: $1,899 for the BenQ TK710STi and $899 for the Optoma GT2000HDR, a $1,000 difference in the Optoma GT2000HDR's favor. Owners praise the BenQ TK710STi for true 4K UHD resolution resolves course textures, grain on greens, and distant fairways far more sharply than the 1080p alternatives and 1.2x optical zoom plus 0.69-0.83:1 throw ratio gives real mounting flexibility — the only projector here that lets you fine-tune image size without moving the mount; the most common complaint is projectorCentral's measurements put real output around 2,478 ANSI lumens in the brightest mode — about 23% below the 3,200 rating, and practical calibrated modes are dimmer still. Owners praise the Optoma GT2000HDR for lowest price of any laser option here while keeping the 0.496:1 short throw, 30,000-hour light source, and IP6X dust sealing and 3,500 lumens is still bright enough for a light-controlled bay and beats every lamp projector in this class; the most common complaint is about 20% dimmer than the GT2100HDR/GT2400HDR — in a garage with ambient light the image washes out sooner.
BenQ TK710STi
- True 4K UHD resolution resolves course textures, grain on greens, and distant fairways far more sharply than the 1080p alternatives
- 1.2x optical zoom plus 0.69-0.83:1 throw ratio gives real mounting flexibility — the only projector here that lets you fine-tune image size without moving the mount
- Very low input lag (4.2 ms at 1080p/240Hz, 16.7 ms at 4K/60Hz) for lag-free simulator response
- 20,000-hour laser light source means no lamp replacements over the life of a home sim
- ProjectorCentral's measurements put real output around 2,478 ANSI lumens in the brightest mode — about 23% below the 3,200 rating, and practical calibrated modes are dimmer still
- At around $1,899 it costs roughly $700 more than the brighter (though 1080p) Optoma GT2400HDR
- Needs about 7 ft of throw for a 10-ft-wide screen — tight bays under 11 ft deep may need the Optomas' 0.496:1 lens instead
Optoma GT2000HDR
- Lowest price of any laser option here while keeping the 0.496:1 short throw, 30,000-hour light source, and IP6X dust sealing
- 3,500 lumens is still bright enough for a light-controlled bay and beats every lamp projector in this class
- 8.6 ms input lag (1080p/120Hz enhanced gaming mode) matches the pricier GT2100HDR
- Ultra-compact chassis is easy to ceiling-mount or shelf-mount out of the swing path
- About 20% dimmer than the GT2100HDR/GT2400HDR — in a garage with ambient light the image washes out sooner
- Amazon stock often comes from smaller third-party sellers with limited quantities
- Fixed lens and 1080p, with no golf-specific picture mode
Which should you buy?
The BenQ TK710STi is the better fit for sim bays 11-16 ft deep where 4K sharpness is the priority and gSPro players who want the lowest possible input lag — it is the higher-scoring pick here, chiefly for Image Brightness & Quality and Throw & Mounting Flexibility. The Optoma GT2000HDR is the better fit for budget builds that still want a maintenance-free laser and basements and rooms with good light control, and the stronger choice if Value matters more to you than the overall score. If the $1,000 saving matters more than Image Brightness & Quality, the Optoma GT2000HDR is the better value. The BenQ TK710STi is a poor fit for bays shallower than about 11 ft (throw distance won't fit); the Optoma GT2000HDR is a poor fit for bright garages where every lumen counts.
Choose the BenQ TK710STi if
- Sim bays 11-16 ft deep where 4K sharpness is the priority
- GSPro players who want the lowest possible input lag

- Bays shallower than about 11 ft (throw distance won't fit)
- Bright garages that need maximum lumens per dollar
Choose the Optoma GT2000HDR if
- Budget builds that still want a maintenance-free laser
- Basements and rooms with good light control
- First simulators that may be upgraded later
Skip it if
- Bright garages where every lumen counts
- Buyers who want guaranteed first-party stock
