distortion, use the Keystone function, a digital technology that can adjust for keystone-type distortion,
resulting in a crisp, square image.
Follow the steps below to manually correct the trapezoid image.
1. Select Menu > Expand > Keystone.
2. Select
• H/V Keystone—Adjusts the projected image when the projector is on the horizontal or
vertical keystone distortion.
• 4-Corner correction—Adjusts the projected image when the projector is keystone distortion
of four corners .
• 6-Corner correction—Adjusts the projected image when the projector is keystone distortion
of four corners.
• Curved correction—Adjusts the projected image when the projector linearity is uneven or
the projected images bent vertically and horizontally.
• Grid image tune—Adjusts the local points of the projected image.
• Reset value—Restores the correction values to the factory defaults.
3. Select OK.
