5. Using On-Screen Menu CORNERSTONE Display the 4-point correction screen and adjust the trapezoidal distortion of the projection screen. Please refer to "Correcting Horizontal and Vertical Keystone Distortion [CORNERSTONE]" (→ page 33) for details on the operation. HORIZONTAL CORNER/VERTICAL CORNER Distortion correction for corner projection such as wall surfaces. HORIZONTAL CORNER Performs correction for projection onto a wall lying at an angle to the horizontal direction. * Reverse angle correction is also possible. VERTICAL CORNER Performs correction for projection onto a wall lying at an angle to the vertical direction. * Reverse angle correction is also possible. NOTE: • When the maximum adjustment range is exceeded, distortion adjustment is disabled. Set up the projector at an optimal angle as the deterioration in the image quality increases as the distortion adjustment volume gets larger. • Please note that the image will go out of focus due to the difference in the distance between the upper and lower or left and right sides and the center of the screen for projections cutting across corners. Lenses with short focal points are also not recommended for projections cutting across corners as the image will go out of focus. 88
