For most installations, the
lens surface of the
Vista
GRAPHX
10K
projector must be parallel
to the screen to prevent
keystoning. To make
small corrections to the projector's level, rotate each leg as necessary to raise or
lower. For angled installations, see “Special Mounting” under 2.3, Projector
Position and Mounting earlier in this section.
Once the Vista
GRAPHX
10K is properly set up and projecting an image on screen,
you are ready to make quick lens adjustments.
Still in the Lens menu, adjust the focus slidebar until you obtain the best overall
image clarity.
If you are using a Vista
GRAPHX
ILS

motorized zoom lens, press /HQV
to display
the Lens menu. Adjust the zoom slidebar to decrease or increase the size of the
image at the current throw distance (range of adjustment is 3-97).
Still in the Lens menu, adjust the horizontal and/or vertical lens offset. The
maximum amount of image shift depends on the lens you are using — see 2.3,
Projector Position and Mounting for details. Adjust until you achieve the best
overall brightness without causing a distortion in picture geometry.
For complete information about adjusting the image through keypad commands
and on-screen menus, refer to Section 3, Operation.
Use serial communication ports when controlling Vista
GRAPHX
10K with a
personal computer having a serial interface or when using the projector with a
Marquee switcher. Vista
GRAPHX
10K serial ports are located on the lower right
portion of the projector's front control panel as shown in Figure 2-16.
