4K short throw at 4000 lumens. The image quality on an impact screen is excellent and the 4K resolution makes a visible difference on outdoor course environments. Short throw keeps the projector out of the hitting zone.

Good 4K short throw for a home sim. The 4000 lumen output handles a semi-dark room and the short throw geometry works in a standard garage setup. Image quality is consistent and Optoma reliability is what you expect.

Pete Y. · ✓ Verified buyer · January 2026

I chose the 4K400STx because I wanted 4K at a short throw distance without going to a laser unit. The image quality delivered what I needed and after three months of daily sessions it has not asked for any attention.

The Optoma 4K400STx works with all major platforms via HDMI — E6 Connect, GSPro, TGC 2019, Creative Golf 3D, Foresight FSX, Trackman, and more.

With a 0.5:1 throw ratio, it projects a 10-foot-wide image from approximately 5.1 feet away.

It uses a standard projector mount (ceiling or shelf). We recommend professional installation for ceiling mounts to ensure correct alignment.

Optoma covers this unit with a 3-year projector / 5-year light source.

Yes — any launch monitor that outputs to a PC or simulator via its software will work. The projector connects to the PC running the sim software via HDMI.
