Will the Optoma ZK431ST-B fit in my simulator room?

Featuring an ultra-short 0.496:1 throw ratio—the tightest in Optoma's golf lineup—the ZK431ST-B is engineered to fit into compact spaces. Because required placement varies based on ceiling height and screen dimensions, reach out to the Turnkey Pro Studios team at sales@turnkeyprostudios.com to calculate exact room measurements before ordering.

Is 4,100 lumens bright enough for my golf setup?

Yes. With 4,100 ANSI lumens, the ZK431ST-B delivers crisp, vivid images in basements, garages, and dedicated indoor rooms with controlled lighting. If you plan to project onto an oversized 150"+ screen or have high natural ambient light, consider stepping up to the 5,000-lumen ZK521ST-B or consult the Turnkey Pro Studios team at sales@turnkeyprostudios.com for guidance.

Does the Optoma ZK431ST-B work with GSPro, E6 Connect, and TGC 2019?

Equipped with dual HDMI 2.0 inputs, the ZK431ST-B displays output from all major golf simulation software platforms, including GSPro, E6 Connect, and TGC 2019. Software compatibility is handled directly through your gaming PC.

What makes the Golf Sim Short-Throw Lens special?

Unlike standard commercial projectors, this model features optics specifically engineered to position the projector extremely close to the screen, eliminating annoying player and club shadows during a swing. Combined with a dedicated Golf Sim Color Mode tuned for lifelike grass and sky tones, it delivers an optimized, realistic course view.

How does the ZK431ST-B compare to the ZK521ST-B?

Both models feature the same build quality, 30,000-hour DuraCore laser light source, True 4K UHD resolution, and specialized golf picture modes. The key differences lie in brightness and throw distance: the ZK431ST-B pairs 4,100 lumens with an ultra-short 0.496:1 throw ratio (best for tight rooms with light control), while the ZK521ST-B offers 5,000 lumens with a 0.79:1 throw ratio (ideal for larger screens or brighter spaces).

What warranty comes with the Optoma ZK431ST-B?

The unit includes Optoma's standard manufacturer warranty (terms vary by region). Contact the Turnkey Pro Studios team at sales@turnkeyprostudios.com for detailed warranty specs or extended coverage options.

What mounting options work with the Optoma ZK431ST-B?

Because of its ultra-short-throw lens design, the ZK431ST-B can be mounted on either the ceiling or the floor. Overhead installations work seamlessly with universal ceiling mounts. For low ceilings or rooms where overhead installation isn't ideal, the short projection distance makes floor placement inside a protective enclosure (Optic Cage Floor Mount Enclosure) just as practical without creating shadows on the screen.
