Correcting trapezoidal distortion of the projected image (Keystone feature)
Normally the Keystone feature automatically adjusts the projected image. The Keystone
feature may not work automatically if the screen is tilted. In this case, set Keystone manually.
1 Press the KEYSTONE key on the remote
commander or select V Keystone in the
Installation menu.
2 Use the V/v/B/b keys to set the value. The
higher the value, narrower the top of the
projected image. The lower the value, the
narrower the bottom.
Note
Since the Keystone adjustment is an electronic
correction, the image may be deteriorated.
Displaying a pattern
You can display a pattern for adjusting the projected image or a grid pattern with the PATTERN
key on the remote commander. Press the PATTERN key again to restore the previous image.
You can use a grid pattern as a guide to write text or to draw lines and shapes on the whiteboard
or blackboard without using a computer.
Note
You cannot use this key when "Type A USB", "Type B USB" or "Network" is selected as the input.
Automatically adjusts Phase, Pitch and Shift of projected image while a
signal is input from a computer (APA (Auto Pixel Alignment))
Press the APA key on the remote commander. Press again to cancel adjusting during the setting.
You can also set APA in the Screen Menu. If Smart APA in the Function menu is set to "On",
executes APA automatically when a signal is input.
