Ideal for Golf Simulators and Tight Spaces
Thanks to its 0.496:1 short throw ratio, the 4K400STx is ideal for golf simulator enclosures where distance from screen to projector is limited. It can project a 120" image from just 4–5 feet away, helping avoid shadow casting and simplifying overhead mounting. Its 4K resolution brings hyper-detailed course visuals to life, while high brightness ensures clarity even in rooms with ambient light.
Brightness and Color Performance
With 4,000 ANSI lumens and HDR10 support, this projector is built for high-impact visuals. Colors appear vibrant and true-to-life, making it equally suitable for immersive sim use, home theater nights, or fast-paced gaming. The lamp-based system delivers vivid whites and deep blacks, enhancing realism on-screen.
Low Input Lag for Real-Time Play
Whether you're using GSPro, E6 Connect, or watching 4K sports, the 4K400STx keeps input lag minimal — critical for accurate feedback during golf swings or fast-paced video playback. With Enhanced Gaming Mode enabled, you'll get responsiveness down to ~16ms.
Setup Tips and Mounting Guidance
For golf sim use, mount the projector roughly 4–6 feet from the screen for a 120–140" image. Ceiling mounts are ideal to minimize obstructions. Use vertical/horizontal keystone correction and 4-corner image adjustment to perfectly align your projection, especially if your mount isn’t centered. Optoma’s compact chassis makes it easy to install even in low-clearance setups.
