distorted:

When the projected image is distorted, carry out any

of the KEYSTONE, CORNERSTONE, and CURVED-

mode adjustments to correct the distortion.

When the image distorts in a trapezoid shape, use the

adjustment. To adjust the image projected on a curved

surface, use the CURVED-mode adjustment.

• When the KEYSTONE-mode adjustment is carried

out, the adjustment value is indicated. Note that

this value doesn’t mean a projection angle.

• When the KEYSTONE-mode adjustment takes

effect, the resolution decreases. In addition, stripes

may appear or straight lines may bend in images

with complicated patterns. They are not due to

product malfunctions.
