Image Projection (Continued)

Correcting Trapezoidal Distortion

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 distortion is called Keystone Correction.

Note

The Keystone Correction can be adjusted up to an angle of approximately ±40 (PG-LX2000)/ ±20 (PG-LS2000) degrees and the screen can also be set up to an angle of approximately ±40 (PG-LX2000)/±20 (PG-LS2000) degrees (When the Resize mode is set to “NORMAL” (see page 28)).
