■Available Keystone Correction Range H/V-Keystone If the projectorʼs angle of tilt is within the following range, you can correct distortion in the projected image by using the H/V-Keystone correction function. • Curved Surface You can correct the image shape if the curved surface is a part of an exact circle. The values in the table are the minimum values for R/L in the illustration. (Approximate value when projecting at maximum zoom.) If the R/L value is lower than the value in the table, you cannot correct the image shape. You can confirm the maximum projection distance (L) using the following formula.
L = R/value in the table Horizontally curved surface 17 Vertical Direction Horizontal Direction -30°-30° -30°-30°
