Functions
Geometry functions are accessed through the Geometry
menu. To display this menu, press
.
Note: It is usually easier to adjust display geometry while
a test pattern (
) is displayed.
Size
The Size function is used to adjust the horizontal and
vertical size of the display image. (This adjustment is
also available through the Picture menu).
To adjust size, select Size from the Geometry menu. Two slidebars are dis-
played: a Horizontal Size slidebar and a Vertical Size slidebar. Press
or
to adjust vertical size, and or to adjust horizontal size until the objects
within your picture have the proper shape. For example, if there is a circle in
your picture, size should be adjusted so that the circle is round, not oval.
Note: The Size function should not be used to compensate for aspect ratio mis-
matches between source images and the projection screen. Not all sources use the
same aspect ratio therefore it may not always be possible to fill the entire screen.
(“Aspect Ratio” is defined in Appendix A).
Keystone
The Keystone function adjusts side keystone geometry distortion. Adjust
keystone to change the width at the top of the display in relation to the
width at the bottom. The displays below demonstrate keystone adjustment.
To adjust keystone, select Keystone from
the Geometry menu then press
or to
adjust the top and bottom widths of the
display as desired.
Side Pin
The Side Pincushion function adjusts pincushion of the sides of the display
image.
The two displays shown below demonstrate side pincushion adjustment.
To adjust side pincushion, select Side Pin
from the Geometry menu then press
or until the sides of the image are
as curved or as straight as desired.
