Basic Operations
Adjusting the Screen Image
When you wish to adjust the projection above or below the range of lens shift adjustment set the projector at
an angle.
When the projector is angled, the projected image may distort into a trapezoid.
Keystone distortion can be corrected within a maximum vertical angle of approximately 15°.

Adjustment procedure
Correcting Keystone Distortion (Keystone)
••••
The image quality will be lower than if the lens shift function is used.
••••
When the lens is shifted to the left or right, complete keystone correction is not possible.
When making keystone corrections set the lens at the center left to right.

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

The keystone correction settings are memorized, so that 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.30)

Keystone correction can also be carried out using the projector menu. (p.33)

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