Correcting Keystone Distortion

When the projector is tilted, it will cause keystone distortion to appear in the image, but this distortion can be corrected using the keystone correction function as long as the vertical angle of tilt is within a range of approximately 15º.

Basic Operations

Projector Projector

•When keystone correction is carried out, the projected image will become smaller.

•The keystone correction settings are memorised. If you change the position or angle of the projector, you may need to readjust the keystone correction settings.

•If the images become uneven in appearance after keystone correction is carried out, decrease the sharpness setting. (p.21, 22)

•If the value displayed in the gauge on the screen stops changing when keystone correction is being carried out, it indicates that the limit for keystone correction has been exceeded. Check that the projector has not been set up at an angle which exceeds the proper limit.
