Adjusting an Image that is not Rectangular
If the projected image is not evenly rectangular, try the following steps until the problem is solved.
Note: Focus and keystone distortion of the projected image are automatically corrected under the
following conditions:
• When the size of the projected image (diagonal length) before correcting focus and keystone distortion
is from 30 to 100 inches.
• When the projection distance is about 28 to 87 inches (0.7 to 2.2 m).
• When the installation angle of the projector toward the projection surface is within 20º right, left, up, or
down.
1. Place the projector directly in front of the center of the screen, facing it squarely, if possible.
2. Make sure that Auto Keystone Correction At Startup and Auto Keystone Correction on
Movement are set to On in the Projector menu.
• Projector > Image Correction > Advanced > Auto Keystone Correction At Startup
• Projector > Image Correction > Advanced > Auto Keystone Correction on Movement
3. Select Auto Keystone Correction in the Projector menu to automatically adjust the image shape.
• Projector > Image Correction > Auto Keystone Correction
4. When projecting on a screen, use Fit to Screen to automatically correct the shape and position of
the image so that it fits on your screen.
• Projector > Image Correction > Fit to Screen
5. Adjust the image shape manually using Manual Keystone Correction in the Projector menu.
• Projector > Image Correction > Manual Keystone Correction
Note: If you cannot correct the focus and any distortion of the projected image, turn off the projector and
disconnect the power cord, then reconnect the power cord and turn the projector back on. If a warning
screen is displayed when you turn on the projector, contact Epson for help.
