automatically correct the focus and any distortion of the projected
image.
Note: Your screen size should be between 30 and
100 inches for automatic image correction. Focus and keystone
distortion are corrected even if the size of the projected image
exceeds 100 inches. However, the adjustment may fail depending on
the installation angle of the projector, the brightness of the
room, and the material of the projection surface. If necessary,
adjust the keystone distortion and focus setting manually using the
projector menu.
