PROJECTING AN IMAGE

Projected image
Use the 3D Reform feature to correct keystone (trapezoidal) distortion to
make the top or bottom and the left or right side of the screen longer or
shorter so that the projected image is rectangular.
You can also use a mouse to correct the Cornerstone distortion. To do so
with your mouse, pick and left-click on one corner of the image you want to
correct.
Do this for the remaining 3 corners. Right-click to display the confirmation
screen.
1. Project an image so that the screen is smaller than the area of the raster.
2. Pick up any one of the corners and align the corner of the screen with the
one of the image.
(The drawing shows the upper right corner.)
3. Press the 3D REFORM button on the remote control.
The CORNERSTONE adjustment screen is displayed.
NOTE: Press the 3D REFORM button to toggle between "Cornerstone" and "Key-
stone."
