1. Physical Screen
Record the physical screen's shape, aspect ratio, and surface.
Choose Wide or Scope
Choose the outline that resembles the physical screen. Wide opens ratios from 16:10 through 2.00. Scope opens ratios from 2.35 through 2.40.

Choose the exact aspect ratio
After choosing Wide, select 16:10, 16:9, 1.85, 2.00, or Custom.

After choosing Scope, select 2.35, 2.37, 2.39, 2.40, or Custom.

Only the list for the selected screen family appears in the menu.
For Custom, enter the aspect ratio directly, such as 2.40:1. The outline updates as the ratio changes.

Choose Flat or Curved
Choose the physical surface. Flat advances without surface correction. Curved adds a curve-correction stage during calibration.

The screen is now fully described. Continue to the projector and optical path.
