Setting V-Keystone Corrects vertical keystone distortion in images.
 When keystone correction is carried out, the 
projected image will become smaller.
 If using both horizontal and vertical keystone 
correction, first make the vertical correction and 
then make the horizontal correction in that order.
 The keystone correction settings are memorized, so 
that if you change the position or angle of the 
projector, you may need to readjust the keystone 
correction settings.
 If the images become uneven in appearance after 
keystone correction is carried out, decrease the 
Sharpness setting.
 If you carry out both horizontal and vertical 
keystone correction, the correction range will 
become smaller than it would be if only one type of 
correction was carried out.Median
