Picture Use the controls in the Picture Menu to calibrate your VX-22i for optimum picture quality.
The VX-22i has been designed to incorporate setup and calibration standards established 
by the Imaging Science Foundation (ISF). The ISF has developed carefully crafted, 
industry-recognized standards for optimal video performance and has implemented a 
training program for technicians and installers to use these standards to obtain optimal 
picture quality from Runco video display devices. Accordingly, Runco recommends that 
setup and calibration be performed by an ISF certified installation technician.
All signal types require separate processing. Therefore, you need to calibrate each input 
separately. 
CinemaCINEMASelect Cinema to view 2.35 
source material in its native 
aspect ratio.
With a 16:9 screen and a 
non-CineWide projector (no 
anamorphic lens), the upper and 
lower portions of the screen are 
masked, but the geometry of the 
active image area is unchanged.
 
 
With a 2.35:1 screen and a 
CineWide-equipped projector, 
the VX-22i scales the 2.35:1 
image so that the active image 
area fills the 16:9 chip surface, 
eliminating the black bars. The 
secondary, anamorphic lens 
then restores the proper 
geometry to the 2.35:1 image. 
Virtual CinemaVCINEA 16:9 image is scaled 
NON-linearly (more on the sides 
than in the center) to fit a 2.35:1 
screen. 
Virtual Cinema is available only 
on the VX-22i/CineWide.

Although it may be possible to obtain satisfactory picture quality using the naked eye and 
regular program material, Runco recommends using the following calibration tools for best 
results: 
 External test pattern source – Ovation Multimedia, Digital Video Essentials or AVIA test 
DVD or equivalent.
 A blue filter (provided with many test DVDs), for color level and tint adjustments.
Connect your test pattern source to the input that you are calibrating and proceed as 
follows. Perform the adjustments in the order listed here.
Brightness: On your external test pattern source, select a PLUGE pattern. (PLUGE is an 
acronym for “Picture Line-Up Generation Equipment.”) 
Figure 4-2 shows a typical PLUGE 
pattern.
Figure 4-2. Typical PLUGE Pattern for Adjusting Brightness
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 or SELECT. 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).
When you change a picture quality setting, save the change to a 
preset afterwards. Otherwise, the change will be lost when a 
different input is selected. (Picture quality settings are saved for 
each input separately.) For information about saving settings, refer 
to 
Memory Presets on page 54.

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 or SELECT. Adjust the contrast to a point just below 
which the white rectangle starts to increase in size.
Color Saturation: On your external test pattern source, select a color bar pattern like the 
one shown in 
Figure 4-4.

Select Color and press ENTER or SELECT. 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 or SELECT. 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.

Sharpness: “Sharpness” is the amount of high-frequency detail in the image. To adjust 
sharpness, select Sharpness from the Picture menu and press ENTER or SELECT. On 
your external test pattern source, select a pattern like the one shown in 
Figure 4-5. Adjust 
as needed, looking for white edges around the transitions from black to gray and 
differently-sized lines in the “sweep” patterns at the top and bottom. Lower the sharpness 
setting to eliminate them.

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. Overscan 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.
Phase: Adjust the phase if the image from an RGB or Component 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 
find that you can stabilize the image at more than one point. Use either setting in this 
case.) 
Memory PresetsFor each input, the VX-22i 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 “THX” 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:


 Color saturation

 Sharpness
To reset the Custom 1 and THX image presets to their factory defaults, select Factory 
Default and press ENTER or SELECT.

CalibrationUse the Calibration menu to perform advanced picture quality adjustments. This menu 
should be used by ISF-certified technicians only. 
To recall the ISF Night or ISF Day settings, select “ISF Night” or “ISF Day” from the ISF 
Presets menu (see 
page 54) or use the corresponding buttons on the remote control. 
ISF Night - Display Color: Use the Display Color settings to adjust the color balance at 
the projector output. These settings are saved independently for each input.
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 (Pr), 
green (Y) or blue (Pr), decrease the Gain for that color.
set: 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 (Pr), green (Y) or blue (Pr), decrease the Offset for that 
color.
 Gamma: “Gamma” 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 (300W; this is the 
default setting) or you can choose the lower (250W) setting. Generally, lower lamp 
output prolongs 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 adjust the color balance of the incoming signal. These settings are 
also saved independently for each input. 
set: 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. 
se Filter: To apply noise filtering to the input signal, select Noise Filter from the 
Input Color menu. The Noise Filter is useful for clearing up noisy images from 480i 
video sources. 
Use the left- or right-arrow buttons to select the desired amount of noise reduction, 
keeping in mind that higher settings (which reduce high frequencies) may also “soften” 
the image.
ISF Day - Display Color: Refer to ISF Night - Display Color. 
ISF Day - Input Image: Refer to ISF Night - Input Image. 
ISF Day - Input Color: Refer to ISF Night - Input Color. 
Save ISF Settings: Whenever you make a change to the ISF settings, you should always 
save it. Select Save ISF Settings from the ISF Calibration menu to do this. In the event you 
ever have to perform a 
System Reset, you can restore the saved ISF settings by selecting 
Restore Saved Settings in the Service menu. (System Reset and Restore Saved Settings 
are described on page 58.)
Output Shift: The controls in the Output Shift menu are similar to those in the Input 
Position menu, except that they change the characteristics of the output signal. These 
settings are saved independently for each aspect ratio. 
Splash Timer: Select Splash Timer from the Calibration menu to set the amount of time 
the Runco/ISF logo “splash” screen appears when you turn on the projector. The range is 
from 5 to 60 seconds, in one-second increments. 
OSD Position: To adjust the position of the OSD, select OSD Position from the 
Calibration menu and press ENTER (or SELECT). 
Press  or  to select “Hor.” or “Ver.” Then, press  or  change the position.
