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.
The Keystone Correction can be adjusted up
to an angle of approximately ±40 (XR-55X)/
±20 (XR-50S) degrees and the screen can
also be set up to an angle of approximately
±40 (XR-55X)/±20 (XR-50S) degrees. •
