d) Keystone correction
Position the projector as perpendicular as possible to the projection surface. If the projector is
not exactly perpendicular to the projection screen, the projected image will appear distorted.
The image will appear wider (or higher) on one side than on the opposite side. To compensate
for this, use the keystone correction on the device. This creates a distortion in the image that
compensates for the existing distortion and creates a normal image for the viewer.
• Turn the
Keystone
selection wheel (3) to correct the image for an undistorted view. You can
correct the image up to a maximum of ±15°.
