Projection angles
The optimum projection screen is acquired by placing the center of the projector ’s lens and a 
right-angle to the screen.
When viewing from the side
* It is possible to move the projection position up and down with the lens shift function
When viewing from the top or bottom
Point
Although the projection angle can be adjusted with the front foot  (see page 43), there are 
cases where the screen will distort into a trapezoid shape. In this event, adjust the trape-
zoid distortion with the trapezoid correction function. (see page 45)
