Frequently Asked Questions
Why is accurate FOV critical for sim racing?
Correct 1:1 true perspective field of view allows your brain to intuitively judge braking distances, cornering apexes, and vehicle yaw speed without spatial distortion.
How do I calculate triple screen side monitor angle?
The side monitors should be angled inward at an angle equal to the single screen horizontal field of view angle, directing the normal of each side display directly into the driver eye position.
How does curved monitor radius affect FOV?
A curved monitor wraps around the driver, reducing the chord distance to the edges and expanding the perceived horizontal field of view compared to a flat screen of identical diagonal size.
