Solutions When the Image is Not Rectangular
If the projected image is not evenly rectangular, try the following solutions:
• If the projector is not mounted on the wall or ceiling, place it directly in front of the screen, lining up the
lens with the center of the screen, if possible.
• Use the Image Shift setting to adjust the image position, rather than moving the projector.
• Press the keystone buttons on the projector to adjust the image shape.
• Adjust the image shape using the individual Geometry Correction settings in the Installation menu.
Note: Adjusting Quick Corner, H/V-Keystone, and Arc Correction settings may affect focus and
pen calibration.
Note: If the projector is mounted on the wall, always use the adjustment dials on the mount to center
the image.
