on the control panel to adjust the images.

However, the image quality will decrease compared to if the lens shift function is used. When the lens is shifted to 
the left or right, complete keystone correction is not possible. When making keystone corrections set the lens at the 
centre left to right.
Keystone distortion can be corrected within a maximum vertical angle of approximately 15˚.

and to make line menu adjustments.
