Correcting Distortion In The Projected Image - Epson EB-Z8050W User Manual

Correcting Distortion in the Projected Image

There are two methods of correcting distortion in projected images as
below.
• Quick Corner
This allows you to manually correct each of the four corners of the
projected image separately.
We recommend using Quick Corner to accurately adjust keystone
distortion.
• H/V-Keystone
This allows you to manually correct distortion in the horizontal and
vertical directions independently. You can perform easy H/V-Keystone
corrections by using the [
w
on the projector's control panel.
Shift the lens to the position shown below when performing
q
horizontal and vertical keystone. When the lens shift is not
positioned as below, the distortion is not corrected accurately.
• The horizontal lens shift is set to the center.
• The vertical lens shift is set to the top or bottom.
The correction may not be properly performed according to the
zoom adjustment value. And, the projected screen size may become
smaller after performing the correction. Be careful about the
projection distance when installing the projector.
Quick Corner and horizontal and vertical keystone cannot be performed
at the same time. When the Keystone correction method is selected
from the configuration menu, the correction method you choose is
assigned to the [ / ], [
w v
control panel. The default setting for Keystone is set to H/V-Keystone,
so when [ / ], [ / ], [
w v
V-Keystone correction is carried out.

Because Quick Corner and H/V-Keystone correction can be carried out
while projecting a test pattern, you do not need to make preparations
by connecting a computer or other equipment.
