Immersive Golf Simulation

Powered by Optoma

The dedicated Golf Sim Mode enhances color tuning to bring brighter blue skies, deeper shadows, and natural green grass tones—making every course look vivid and true to life.

Optoma’s short-throw projectors enable high-quality golf sim setups in tight spaces. By positioning the projector closer to the screen, golfers can reduce shadows and gain more usable hitting area for an immersive experience.

Optoma’s high-brightness laser projectors maintain vivid, clear images even in brighter rooms, ensuring fairways, greens, and ball flights look true to life at any time of day.

Optoma supports multiple aspect ratios (16:9, 16:10, 4:3, 1:1) and geometric correction to ensure your projection fills the screen perfectly.

Optoma Smart Control mobile app provides purpose-built display tuning for third-party golf simulation software such as GSPro, delivering a more realistic, visually accurate, and immersive experience.

Laser technology

Optoma laser projectors use high-quality lasers to create the projected image.

They also deliver increased efficiency to maintain consistent brightness, superior color performance, instant on/off and an extraordinary life span of up to 30,000 hours (Eco mode).
