Adjusting the image with 2D keystone
2D keystone distorts the projected image both vertically and horizontally simultaneously and
resembles a trapezoid.
Adjusting horizontal or vertical keystone correction after 2D keystone erases the 2D keystone settings;
however, performing 2D keystone after horizontal or vertical correction retains the previous keystone
setting.
1. Select MENU > Configuration > Geometry Correction > Geometry correction Mode.
2. Select 2D Keystone Correction.
3. From the correction dialog, select the corner to adjust.
4. To make the keystone adjustments, use the arrow keys to change both the vertical and
horizontal values.
5. Select Apply Changes.
Adjusting vertical keystone
Use vertical keystone to correct a keystoned image shape in which the top and bottom borders of the
image are unequal in length, and both sides of the image are inclined toward the top or bottom edge.
If vertical keystone adjustments have been made, starting horizontal keystone adjustments erases the
vertical settings.
1. Select MENU > Configuration > Geometry Correction > Geometry Correction Mode.
2. Select Vertical Keystone Correction.
3. From the correction dialog, adjust the vertical keystone by using the arrow keys.
4. Select Apply Changes.
Adjusting horizontal keystone
Use horizontal keystone to correct a keystoned image shape in which the left and right borders of the
image are unequal in length, and the top and bottom are slanted to one of the sides.
If horizontal keystone adjustments have been made, starting vertical keystone adjustments erases the
horizontal settings.
