Triple-screen calculator
Find the right monitor angle and rig footprint from just your screen size and viewing distance.
1. Enter your setup
You only need the size of one monitor and the distance from your eyes to the centre screen.

Use native triple-screen projection when your simulator supports it.
How the angle is calculated
The recommended toe-in equals the horizontal visual angle of one panel: 2 × arctangent of half the visible panel width divided by eye distance. With that placement, each side panel faces the driver and all three panel centres are the same distance from the eyes. Total geometric FOV is three times the per-panel angle.
Values to enter in the simulator
For native triple projection, enter three flat screens, physical monitor width, single-seam bezel width, eye distance, and the calculated side angle. Vertical-FOV titles keep the per-panel vertical value; do not enter the full three-screen horizontal value into a vertical-FOV field.
