typical step-by-step manual resizing procedure. To adjust the first six options,
use the

+RUL]RQWDO#0DUJLQ
Moves the image left or right, essentially by displacing it with the left margin
amount you specify. When moved as far as possible to either side, the image
aligns with the edge without loss or wrapping to the opposite side. Note that the
margin is limited by the size of the image set in Horizontal Display, below.
Range: 0-1023 pixels
9HUWLFDO#0DUJLQ
Moves the image up or down, essentially by displacing it with the top margin
amount you specify. When adjusted as far as possible up or down, the image
aligns with the edge without loss or wrapping to the opposite edge. Note that the
margin is limited by the size of the image set in Vertical Display, below.
Range: 0-767 lines
+RUL]RQWDO#LVSOD\
Stretches or compresses the image horizontally. The value you choose for this
setting determines how many pixels are used across the display. Note that only
even-numbered values can be specified and that the horizontal display setting
cannot be more than twice the horizontal capture setting.

Stretches or compresses the image vertically. The value you choose for this
setting determines how many lines from top to bottom are used for displaying the
image.
Range: 1-768 lines
+RUL]RQWDO#&DSWXUH
Determines what portion of the image is displayed horizontally, much like a
zoom function. The horizontal capture setting represents the number of active
pixels present across the image—i.e., this value should match the horizontal
resolution of your current source in normal situations where you want to see the
entire image. Horizontal Capture adjustments are most useful for tweaking
default settings. The higher the setting, the smaller the image. Note that the
horizontal capture setting cannot be less than half of the Horizontal Display
setting.
NOTE: The adjustment increments represent individual pixels, however the
image changes at 16-pixel increments only.
Ranges: 160-1024 for graphics; 3-864 for video.
9HUWLFDO#&DSWXUH
Determines what portion of the image is displayed vertically, much like a zoom
function. The vertical capture setting represents the number of active lines
present from top to bottom—i.e., this value should match the vertical resolution
of your current source in normal situations where you want to see the entire
image. Vertical Capture adjustments are most useful for tweaking default
settings. The higher the setting, the smaller the image. For interlaced video
images, this value should be half the resolution of the source signal.
Range: 80-1024 lines for graphics; 224-240 lines for NTSC video; 224-288 lines
for PAL video.

 Adjust both Horizontal and Vertical Display so that the image is sized in
each direction as desired for your application.
 NOTE: If the Horizontal Display setting appears to stop prematurely at
too low a setting, it is possible that the current Horizontal Capture
setting is too low and is interfering. If so, increase the Horizontal
Capture first.

 If necessary, re-adjust Horizontal Margin and/or Vertical Margin until
the image is placed exactly where you want it.

 Repeat Steps 3 and 4 until you are satisfied with both the size and
placement of the image. If necessary, double-check your main
Horizontal Position and Vertical Position settings in the Size /

From the Resizing menu, use “Presets” to quickly display an image in its native
resolution (including anamorphic) or to automatically resize an image to fill the
screen. Capture and/or Display values
will, in turn, automatically change as
necessary without your having to set
them manually.

“Full Screen” option is in effect — NTSC, PAL or SECAM images

graphic image will resize from its native resolution (or from current
Display values, if they have been adjusted previously) to use all
pixels (1024 x 768), so that there are no borders or margins. In
addition, both Display values will change to their maximums. Full-
screen video images will resize to fill the screen vertically. A non-
HDTV anamorphic image (originally 16:9) will be stretched
vertically. With the exception of HDTV (16:9), the “Full Screen”
setting results in a 4:3 display.
 
 If desired, you can display a portion of your image “full screen” (like a

available (top and bottom will be black). In addition, the Display
values will change to reflect the 16:9 ratio — the Horizontal value
will be 1024 and the Vertical value will be 582. If you do not choose
the anamorphic option when an anamorphic (wide-screen) image is
present, the image will appear vertically stretched into a 4:3 image.

Adjusts the sharpness of the video image. Use

sharp as possible, keeping in mind that any level of detail above 50% will
increase the level of detail as well as introduce some level of noise in the image.
Set below 50% to filter the signal and remove noise from a noisy source. Keep at
50% to apply no detail.

Applies either a preset color temperature (3200, 5400, 5800,
6100, 6500, 9300) or a Custom or Interpolated color
temperature to the image. All are measured in degrees
Kelvin and represent the coloration (reddish or bluish) of
the whites displayed by the projector — the lower the
temperature, the more reddish the whites, the higher the
temperature, the more bluish the whites. Use the following
as a guide for most applications:

To adjust, 
increase the drive level for a color that appears too weak in the
test pattern (i.e., one that is less than 73). Try not to 
reduce a drive, as low
settings can reduce overall projector brightness. Also keep in mind that
setting a drive level over 73 will limit the number of discernible grays and
produce an uneven color temperature across the grayscale.
 NOTES: 1) Always try to achieve the desired effect by first increasing the
drive level for the color judged to be weak. If the drive level for that color
is already at 73, then decrease the contrast level for one or more of the
other colors. 2) If you want to adjust each color individually, you can
connect only one signal cable — red, green or blue — at a time.

 When the grayscale appears as you want, select Return. You can now use
this temperature with the current source.

If Auto is checked, the projector will automatically
detect the video standard present and display this
standard in the adjacent box. If Auto is unchecked,
press 
 at the adjacent pull-down list to view or
select a different video standard from a complete list
available to the projector. Selecting a specific standard
forces the projector to process the signal according to
this standard. Re-check the Auto checkbox to return to automatic detection of
the standard.
NOTE: This option should remain set at auto for all instances EXCEPT: 1) a
poor quality input signal or 2) a black-and-white video signal. In order to detect
and display such signals, uncheck Auto and specify the relevant standard.

If Auto is checked, the projector will automatically detect
the type of signal present (unless it is RGB-Video or YUV)
and will display the signal type to the left in the adjacent
box. If Auto is unchecked, press 
 at the adjacent
pull-down list to view or select a different signal type from
a complete list available to the
projector. Re-check the Auto
checkbox whenever you want to return
to automatic detection of the signal
type.
NOTES: 1) RGB-Video (which requires a
third-party decoder) and YUV signals
cannot be automatically recognized — if
you use either of these sources, you must select the corresponding signal type from
the list.  2) It is recommended that this option remain set at auto for other signal
types. 3) If you are using the VDI optional interface, Signal Type will be “auto”  and
the option list disabled.

The baud rate setting determines the speed of communications
to and from the projector. It is important if you are controlling
the projector with an external device such as a computer or
another projector via an RS-232 or RS-422 port. The
Vista
GRAPHX 10K baud rate must be set to match the baud rate
of the controlling device. If you are unsure about what baud
rate to assign, refer to the documentation for the controlling device. By default,
the projector baud rate is set to 9600.
NOTE: 
1) The baud rate setting does not affect the switcher port, which is
always 9600 baud. 
2) See 
2.9, Serial Port Connections and 
Appendix D for
more information about cable connections between devices.
