Keystone Correction (Correcting Trapezoidal Distortion)

Correcting Trapezoidal Distortion

This function allows for Keystone (On-screen Trapezoidal Distortion) Correction.

Note

•When the image is projected either from the top or from the bottom towards the screen at an angle, the image becomes distorted trapezoidally.

The function for correcting trapezoidal dis-

tortion is called Keystone Correction.

•You can select “Auto” or “Manual” for the Keystone Correction mode. (See page 44.)

•The Keystone Correction can be adjusted up to an angle of approximately ±12˚ when the Keystone Correction mode is set to “Auto”, or approximately ±35˚ when set to “manual” (when the picture display mode is set to “NORMAL” (see page 40)). Therefore, the actual screen can be diagonally set up to that angle as well.
