PLUGE patterns vary but generally consist of some combination of black, white and gray 
areas against a black background. The example above includes two vertical bars and four 
shaded boxes.
Select Brightness from the Picture menu and press ENTER. Adjust the brightness so that:
 The darkest black bars disappear into the background. 
 The dark gray areas are barely visible.
 The lighter gray areas are clearly visible.
 The white areas are a comfortable level of true white.
 The image contains only black, gray and white (no color).
Contrast: On your external test pattern source, select a stepped, gray-bar pattern like the 
one shown in 
Figure 4-3. 
Figure 4-3. Typical Gray Bar Pattern for Adjusting Contrast
Select Contrast and press ENTER. Adjust the contrast to a point just below which the white 
rectangle starts to increase in size.
Brightness and contrast controls are interactive. A change to one may 
require a subtle change to the other in order to achieve the optimum 
setting. Note

Color Saturation: On your external test pattern source, select a color bar pattern like the one 
shown in 
Figure 4-4. 
Figure 4-4. Typical Color Bar Pattern for Adjusting Color Saturation and Tint
Select Color and press ENTER. While looking at the color bar pattern through a blue filter, 
adjust the color saturation level until the outermost (gray and blue) color bars appear to be a 
single shade of blue: 
Tint: Tint or “hue” is essentially the ratio of red to green in the color portion of the image. 
When tint is decreased, the image appears redder; when it is increased the image appears 
greener. To set the tint, select Tint and press ENTER. While looking at the color bar pattern 
through a blue filter, adjust the tint level until the cyan and magenta color bars (on either 
side of the green bar) appear to be a single shade of blue. 
Like the brightness and contrast controls, the color and tint controls are 
interactive. A change to one may require a subtle change to the other in 
order to achieve the optimum setting.

OverscanWhen you change an input position setting, save the change to a preset 
afterwards. Otherwise, the change will be lost when a different input is 
selected. (The input position settings are saved for each input and 
resolution separately.) For information about saving settings, refer to 
ISF 
Presets on page 4-10. 
Note 
						

							Operation
4-10 Vidikron Vision Model 90 Owner’s Operating Manual
Overscan: Image Overscan pushes the outside edge of the active picture area of the video 
signal out beyond the edge of the display area. 
Some television programs are produced based on the assumption that older television sets 
may not display the outer edges of the broadcast picture area. Over scan effectively trims 
away these inactive, outer edges and enlarges the remaining portion of the image to fill the 
display area.
Select from 1% to 10% of Overscan, as desired.
For HDTV, DVDs and other video sources, Overscan is generally not necessary or desirable.
ISF Presets For each input, the Vision 90 lets you save image quality settings as presets that you can 
recall at a later time. You can create up to four presets per input and resolution. Use the ISF 
Presets menu to recall saved image presets, or to save image settings in the “Custom 1” or 
“Custom 2” memory location. The currently-selected preset is indicated by a “
7” to its left; in 
the example shown here, ISF Night is selected. 
You should save changes to any of the following settings to a preset; otherwise they will be 
lost when a new input source or resolution is selected:
 Aspect ratio
 Picture quality settings (brightness, contrast, color saturation, tint and sharpness)
 Input position (image position, width, height and overscan percentage)
To reset all image presets to their factory defaults, select Factory Default and press ENTER. 
Information Select Information from the Main Menu to see information that uniquely identifies your 
projector: its serial number, the installed hardware and firmware versions and the firmware 
version build date. Should you ever need to contact Vidikron Technical Support, this 
information will help them answer your questions or resolve product performance issues. 
Calibration Use the Calibration menu to perform advanced picture quality adjustments. This menu 
should be used by ISF-certified technicians only. 
The changes you make here take effect immediately; you do not need to save them. To recall 
the ISF Night or ISF Day settings, select “ISF Night” or “ISF Day” from the ISF Presets menu (see 
above).

ISF Night - Display Color: Use the Display Color settings to change the characteristics of the 
output signal. These settings are global (independent of any particular input). 
•Gain: Use the Gain controls to correct color imbalances in the bright areas of the image. A 
good way to do this is to use a test pattern consisting mostly of solid white areas, such as 
an 80 IRE “window” pattern. If the white areas contain traces of red, green or blue, 
decrease the Gain for that color.
• Offset: Use the Offset controls in the White Balance sub-menu to correct color imbalances 
in the dark areas of the image. A good way to do this is to use a test pattern consisting 
mostly of dark gray areas, such as a 30 IRE “window” pattern. If the gray areas contain 
traces of red, green or blue, decrease the Offset for that color.
•Gamma: “Gamma” is a global setting that determines how gray shades are displayed 
between minimum input (black) and maximum input (white) for all signals. A good 
gamma setting helps to optimize blacks and whites while ensuring smooth transitions for 
the “in-between” values utilized in other grays. Unlike “Brightness” and “Contrast” 
controls, the overall tone of your images can be lightened or darkened without changing 
the extremes and all images will be more vibrant while still showing good detail in dark 
areas. 
In all but the most unusual situations, the appropriate “Color Temp” selection (see below) 
will produce accurate colors and a satisfying contrast level. However, it is sometimes 
necessary to adjust the red, blue and green gamma curves individually. To do this, select 
Gamma from the Display Color sub-menu and use the left- and right-arrow buttons to 
manipulate the on-screen slidebars. 
•Lamp Power: Select Lamp Power from the Display Color Menu to adjust the lamp output 
level. You can choose to run the lamp as bright as possible (“1”; this is the default setting) 
or you can choose the lower setting (“0”). Generally, lower lamp output can prolong the 
life of the lamp, but decreases brightness. 
• Color Temp: Select Color Temp from the Display Color menu to adjust the color 
temperature. The default setting is appropriate for most situations. Higher settings 
produce a “bluer” picture. 
ISF Night - Input Image: The Input Image controls are similar to those in the Picture menu, 
but are accessible only by entering the Calibration menu passcode. This makes it possible to 
restore the picture quality settings to what they were when the projector was installed, 
simply by recalling the “ISF Night” preset. 
ISF Night - Input Color: The Input Color controls are similar to those in the Display Color 
menu (see above), but can be set independently for each input. 
• Gain/Offset: Refer to ISF Night - Display Color, above. 
• Chroma Delay: use the Chroma Delay control to correct a mis-aligned image from a 
Composite, S-Video or Component video source. Chroma delay in an image causes color 
shifts to occur to the left of the vertical edge transitions, producing artificial shadows or a 
“halo” effect. If necessary, adjust this setting to eliminate them. 
•Phase: Adjust the phase if the image (usually from an RGB source) shows shimmer or 
“noise.” Pixel phase adjusts the phase of the pixel sampling clock relative to the incoming 
signal. The effect of this control is similar to that of a tracking control on a VCR. 
For best results, use a good test pattern such as a smooth gray consisting of a clear pattern 
of black and white pixels, or a similar “half on, half off” graphic image. (You may notice 
that you can stabilize the image at more than one point. Use either setting in this case.)

Remote Control: The Remote Control menu shows you the primary and secondary infrared 
(IR) codes to which the Vision 90 will respond. By default, both are set to 17. You can change 
these codes if either:
 Another device in the theater (a DVD player, for example) is responding to commands 
from the Vision 90 remote control in ways that are unpredictable or undesirable. 
 You have multiple Vision 90 projectors and want to control them independently, as 
opposed to broadcasting commands from a single remote to all of them. In this scenario, 
you can use multiple remotes programmed to use different IR codes. Or, you can use a 
single remote and change the IR code as needed to address a specific projector.
When you change a remote code on the Vision 90, you must re-program your remote control 
to send that same code. To do this:
1. Using a straightened paper clip or similar object, press and hold the CODE button on the 
remote control for approximately three seconds, or until the red LED on the remote 
lights solid red.
2. Enter a new two-digit code between 00 and 31 inclusive. Use the ANA button for “9” and 
the 4x3 button for “0.” Include a leading zero for single-digit codes; for example, enter 9 
as “09.”
3. The LED turns off to confirm the code change. If you enter an invalid code, the LED 
flashes for three or four seconds. Try again, entering a valid code. 
Display Device: The options in the Display Device menu allow you to change the picture 
orientation, reset the lamp timer, perform lens adjustments and access additional test 
patterns. 
• Installation: select Installation from the Display Device menu to change the picture 
orientation to suit the method of installation (Floor Front, Floor Rear, Ceiling Front or 
Ceiling Rear). 
This menu page also displays the number of hours that the lamp has been in service, and 
lets you reset the counter (which is recommended after you replace the lamp; refer to 
Lamp Replacement on page 5-1). 
•Lens: Select Lens from the Display Device menu to access the motorized lens controls. 
Refer to 
Lens Adjustments on page 4-2. 
•Diagnostics: Select Diagnostics from the Service menu to access additional test patterns 
for calibration or measurement purposes:
 Select Red, Green or Blue to display only the selected color (simulating a filter of that 
color). 
 Select 75 or 100 to display color bars (75 IRE or 100 IRE). 
 Select Horz or Ver t to display a horizontal or vertical gray ramp. 
 Select Checks to display a 15-segment checkerboard pattern. 
 Select Align to display a white grid against a black background (useful for verifying 
proper image or screen alignment). 
HD Format: If for some reason the Vision 90 does not properly detect the incoming signal 
format (color space) on the HD1 or HD2 inputs, specify it here (RGB or YUV). Otherwise, leave 
it set to Auto. 
Use the rear-panel keypad to change a projector IR code. Then, change the 
code sent by the remote to match as described below. Tip
