Optoma GT2400HDR
Optoma's newest short-throw laser, and the first in its GT line marketed explicitly as golf-simulation-ready, with a dedicated golf sim picture mode. It pairs the brightest output in this group (4,200 lumens) with the lowest input lag (8.4 ms at 1080p/120Hz) and a 0.496:1 fixed lens that fills a 100-inch image from about 3.6 feet — ideal for bays as shallow as 10 feet. The DuraCore laser is rated for 30,000 hours and the optical engine carries an IP6X dust-protection rating, a meaningful spec for garage bays full of turf fibers and ball debris.

Our Verdict
Nearly all of the practical golf-sim performance for $700 less than the BenQ: it's the brightest projector here at 4,200 rated lumens, has the group's lowest input lag at 8.4 ms, adds a dedicated golf sim picture mode, and its IP6X-sealed 30,000-hour laser is built for dusty garage bays. It beats the older GT2100HDR on the golf mode, marginally lower lag, and first-party Amazon stock; only the TK710STi's 4K image and zoom flexibility keep it from the top spot.
Score Breakdown
Pros & Cons
Pros
- •Brightest pick here at 4,200 rated lumens — the safest choice for garages and rooms with ambient light hitting the impact screen
- •Lowest input lag of the group at 8.4 ms (1080p/120Hz), with a dedicated golf sim picture mode tuned for grass and sky tones
- •0.496:1 throw fills a 100-inch image from about 3.6 ft, fitting even very shallow bays with the projector safely out of swing range
- •IP6X dust-sealed optics and a 30,000-hour laser suit dusty garage installs; sold and shipped by Amazon directly
Cons
- •1080p resolution — course detail is visibly softer than the BenQ TK710STi's 4K image on a large screen
- •Fixed lens with no optical zoom means mounting position must be calculated exactly; all image-size adjustment is physical
- •New to market in 2025, so long-term owner feedback is still thin compared with the GT2100HDR and TH671ST

Alternatives to Consider
BenQ TK710STi
BenQ
The only true 4K projector in this group, and the sharpest image you can put on an impact screen without leaving Amazon. Its 3,200-lumen laser light source (ProjectorCentral's lab measured about 2,478 ANSI in the brightest mode) runs up to 20,000 hours with no lamp swaps, and its 0.69-0.83:1 short-throw lens with 1.2x optical zoom fills a 10-foot-wide screen from roughly 7 feet — with real placement flexibility the fixed-lens Optomas below can't match. Input lag is exceptional: 4.2 ms at 1080p/240Hz and 16.7 ms at 4K/60Hz, so GSPro and E6 ball flight renders effectively instantly.
Optoma GT2100HDR
Optoma
The established favorite among golf-sim builders — Golfstead's 2026 guide ranks it the #1 golf simulator projector outright — and the projector the newer GT2400HDR is built to succeed. It delivers the same 4,200-lumen DuraCore laser and 0.496:1 fixed short throw as its successor, with 8.6 ms input lag at 1080p/120Hz and an IP6X dust-resistant engine rated for 30,000 hours. It typically sells for less than the GT2400HDR, making it the cheapest route to Optoma's full-brightness laser platform.
Optoma GT2000HDR
Optoma
The cheapest laser projector in this group, and the budget pick that doesn't give up the specs that matter most for a sim bay. It keeps the same 0.496:1 fixed short throw, 30,000-hour DuraCore laser, IP6X dust rating, and 8.6 ms gaming input lag as its bigger siblings, trading down only on brightness — 3,500 lumens versus their 4,200. Golf-sim specialty retailers including The Indoor Golf Shop, Golf Sim Depot, and Top Shelf Golf all sell it specifically as a golf simulator projector.
BenQ TH671ST
BenQ
The longtime default recommendation for entry-level golf simulators — Carl's Place, Rapsodo, and PGA Tour Superstore all sell it packaged specifically for sim bays, and BenQ maintains a dedicated golf-simulator page for it. Its 3,000 ANSI lumens, 0.69-0.83:1 short throw with 1.2x optical zoom, and 16.7 ms input lag remain a proven, well-documented formula. The catch in 2026: it uses a lamp rather than a laser, and at its current Amazon price it costs more than the brighter, laser-based Optoma GT2000HDR.
