OPERATION
PIC 2 Size
The Size function is used to adjust the horizontal and vertical size of the display image.
(This adjustment is also available through the Geometry menu.)
To adjust size, select Size from the Picture menu. Two slidebars are displayed:
a Horizontal Size sliders and a Vertical Size slidebar. Press UP or DOWN to adjust
vertical size and LEFT or RIGHT 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 mismatches
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).
PIC 3 White Balance
The White Balance function is used to select or adjust the color temperature (or shade) of
white used by the projector. For most applications, the white balance setting set by the
factory is satisfactory.
To select or adjust the white balance, select White Balance from the Picture
menu. From the White Balance menu, select item 1, 2 or 3 to use a standard color
temperature. Select option 4 to use the service adjusted user setting. Select option 5 to
make a custom white balance adjustment. The current selection is indicated by a check
mark. lf option 5 is selected, a White Balance slidebar is displayed. Press
UP or DOWN
to adjust white balance. 0% is 3200K, 50% is 6500K, and 100% is 9300K.
PIC 4 FOCUS
The Focus function is used to adjust the electrical focus of the combined red, green, and
blue color components.
To adjust focus, select Focus from the Picture menu then use UP and DOWN
until the center of the display appears the sharpest. If the displayed image cannot be
adequately focused, a service adjustment to the electrical focus may be required or an
optical focus adjustment is necessary. Refer to the section 2.8,
Optical Alignment for
optical focus instructions.
PIC 5 Sync (Fast/Slow)
The Sync function is used to minimize horizontal jittering, ''flag waving'' or tearing at the
top of the display image. This effect sometimes occurs when the source is a VCR
or
video signal. The function changes the synchronization mode of the projector from fast to
slow, or slow to fast.
