Optoma GT2000HDR Review

The Optoma GT2000HDR is the most practical short-throw laser projector for home golf simulator builds right now. It matches the throw ratio of the discontinued BenQ LH820ST, adds HDR10 support, costs less, and uses a laser light source rated for 30,000 hours. For anyone building a new simulator today in the $900–$1,200 projector budget, this is the default recommendation.

Key specifications

Throw ratio and placement

At 0.496, the GT2000HDR's throw ratio is nearly identical to the BenQ LH820ST's 0.497. In practical terms this means the same placement options: floor-mount in front of the screen at ~3.5–6 ft, or ceiling-mount close to the screen end of the bay. A 10 ft wide image needs about 5 ft of throw distance. A 12 ft wide image needs about 6 ft.

The GT2000HDR has a simpler lens offset profile than the LH820ST, which makes ceiling mounting slightly more straightforward for some setups. Standard ceiling mount brackets are compatible — the unit weighs around 6 lbs and uses a standard 1/4"-20 mount thread.

Brightness and image quality

At 3,500 ANSI lumens, the GT2000HDR is bright enough for most home simulator environments. A garage with the door closed and no direct sunlight, a basement room, or a dedicated space with controlled overhead lighting all work well. The image stays clear and watchable with modest ambient light present.

The 300,000:1 contrast ratio is lower on paper than the LH820ST's 3,000,000:1 — but that LH820ST figure is dynamic contrast achieved through laser dimming, not native contrast. In real-world viewing conditions the two projectors look comparable. The GT2000HDR's colour reproduction is accurate without a dedicated Golf Mode, which BenQ's golf-specific models include but Optoma's don't. In practice the difference is minor — simulator software renders course colours independently of the projector's colour profile.

HDR10 and HLG support is a genuine improvement over older 1080p projectors in this category. Golf simulator courses that include HDR metadata display with better depth and colour punch. Whether you notice the difference depends on the software and course — GSPro and E6 Connect both benefit from HDR-capable displays.

Laser vs the alternatives — why it matters

The 30,000-hour laser rating is the GT2000HDR's most practically significant specification. At two hours of use per day, that's 40+ years of rated life — effectively maintenance-free for any realistic home use. There's no lamp to replace, no colour shift to manage as the lamp ages, and no warm-up wait — the projector reaches full brightness instantly when you turn it on.

Compare this to the BenQ TH671ST at a similar price point: the TH671ST uses a lamp rated at 10,000 hours in eco mode. At two hours per day of regular use, that's roughly 13 years before the lamp hits its rated life — but actual brightness degradation becomes visible well before then. Lamp replacement costs $50–$100 and requires removing the projector from its mount. For a permanent simulator installation, laser is simply less friction.

Room requirements

The GT2000HDR works in rooms as short as 12 ft deep. With the projector floor-mounted at 3–4 ft from the screen and the hitting position at 10–12 ft from the screen, there's comfortable separation between the projector and the golfer. For ceiling mounting from the back of a 16–20 ft bay, add an extension drop to get the projector closer to the screen rather than mounting directly at the ceiling at the rear.

Ceiling height is not a concern for the projector itself — it's determined by your swing clearance requirements, not projector placement. The GT2000HDR's compact size and standard mount compatibility make both floor and ceiling installation straightforward.

What you give up vs the BenQ LH820ST

The GT2000HDR doesn't have Golf Mode (BenQ-exclusive colour profile), doesn't have IP5X dust sealing (relevant mainly in very dusty garages), and doesn't have the 2D keystone correction with corner fit that the LH820ST offered. The contrast ratio figure is lower on paper. None of these are significant in most builds, but the lack of dust sealing is a real consideration if your garage is particularly dusty.

Verdict

The GT2000HDR is the strongest option currently available in the $900–$1,100 short-throw laser projector category for home golf simulators. The combination of 0.496 throw ratio, 3,500 lumens, 30,000-hour laser, HDR10 support, and sub-16ms input lag covers every practical requirement for a home simulator build. It's the projector we'd recommend for most new mid-range builds.

Frequently asked questions

GT2000HDR vs BenQ TH671ST — which should I buy? If budget is the priority, the TH671ST at ~$950 saves roughly $100–$200 and is a capable projector. If you want laser reliability without lamp replacement, the GT2000HDR is worth the modest premium. For a permanent installation, laser is the better long-term choice.

Does the GT2000HDR work with GSPro and E6 Connect? Yes. It connects via HDMI 2.0 and is compatible with all major golf simulator software. The HDMI 2.0 connection supports 1080p at 120Hz, which gives smooth motion during gameplay.

Can I use it in a garage? Yes. The 3,500 lumens handles typical garage lighting conditions well with the door closed. Direct sunlight through an open garage door will wash out the image regardless of projector — close the door during play.

Do I need a protective enclosure for floor mounting? Yes. Any floor-mounted projector in a simulator bay should be in a protective housing. ProGuard and Carl's Place both make floor mount guards compatible with the GT2000HDR's dimensions. Measure the unit (approximately 11.8" × 3.9" × 8.1") before selecting a housing.
