Projection Operations
The angles shown in the above illustration are subject to the following conditions.
Projection of an image from a computer (Resolution: 1024 × 768; Vertical Frequency: 60Hz)
Resize Image To Fit: On
Actual correction ranges are affected by the type of signal being projected, zoom, the
"Resize Image To Fit" setting, the aspect ratio setting, and other factors.
Keystone correction can cause the corrected image to be smaller than the original
(uncorrected) image, or it can cause distortion of the image. If the projected image
becomes difficult to view, try moving the screen and/or projector so they are oriented
close to the configuration shown under "Setting Up the Projector" in the "User's Guide
(Basic Operations)".

Auto Focus.
Pressing the [AF/AK] key projects an alignment chart that comes
in handy when the projection distance is relatively far or when
projecting at an angle. With the Continuous AF/AK mode, the
projector continually performs Auto Focus as the projector is
moved. For details about using the Continuous AF/AK mode, see
"Performing Auto Focus and Auto Keystone Correction while
Continuous AF/AK is Enabled", below.
Pressing the [AF/AK] key again performs Auto Focus only.
