Adjusting the Screen Image
12
If the projector is set up so that it is at an angle to the screen, a type of distortion known as "keystone
distortion" may occur.
Keystone correction can be carried out if the angle of the projector is within a range of approximately 15°
vertically from the perpendicular.
Procedure
Correcting Keystone Distortion
•
••
•
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.27, 29)
•
••
•
Keystone correction can also be carried out using the projector menu. (p.31)
•
••
•
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.
