PROJECTING AN IMAGE FROM THE COMPUTER
• The result of keystone adjustment is memorized. If the projector installation
position is the same as before, keystone adjustment is not required.
• When Keystone Adjustment is selected, signals are processed digitally. The
image may look different from the original one.
• The aspect ratio of the image may change when keystone is adjusted.
• Keystone can be adjusted vertically and horizontally within the range of +/-20
degrees. The amount of adjustment varies depending on the combination of the
amount of optical zooming, input signal type, and adjustment direction (vertical
or horizontal).
• If the keystone distortion is too large to adjust, move the projector installation
position.
• To cancel the keystone adjustment, press the [KEYSTONE] button again to
display [Keystone Reset]. Then, press the [OK] button.
