■ Setting “SCREEN ASPECT”
It is necessary to set the screen aspect ratio (4:3 or 16:9) depending on your screen in order to properly project images on the entire area of
the screen. When the 16:9 screen is used and “SCREEN ASPECT” is set to “16:9”, it is possible to project 4:3 video signals on the entire
screen without losing any part of the image off screen. It is also possible to adjust the projected image vertically as described in the next
section. See “SCREEN ASPECT” in the menu group 4 described on page 17.
