Letterbox LET
BOXLetterbox mode scales (zooms 
in on) a 4:3 image linearly (by the 
same amount on all sides) to fill 
a 16:9 display. 
Letterbox is best suited for 
viewing LaserDisc movies or 
“full-screen” DVDs on a 16:9 
screen.
VirtualWide V-WIDE VirtualWide scales a 4:3 image 
NON-linearly (more on the sides 
than in the center) to fit a 16:9 
screen. 
On a 2.35:1 screen, the image is 
centered between black bars on 
either side. 
Cinema CINEMA Select Cinema to view 2.35 
source material in its native 
aspect ratio.
With a 16:9 screen and a 
standard X-400d/X-450d 
(without an 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 an 
anamorphic lens, the Dimension 
Digital Controller 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.

ScreenThe Screen Menu allows you to recall multiple sets of stored values for certain controls 
(Output Shift, Image Alignment and Screen Masking) that are saved for each aspect ratio. 
Such settings are also saved “per screen.” To recall the Output Shift and Image Alignment 
settings associated with “Screen 1” or “Screen 2,” make that selection here.
Virtual Cinema V-CINE A 16:9 image is scaled 
NON-linearly (more on the sides

screen. 
Native NATIVE Select Native to display the 
source signal in its native 
resolution, centered in the 
display area with no re-sizing or 
overscan. 
This means, for example, that 
720p HDTV programs will 
display with unused pixels on all 
sides: 320 on the left and right 
sides and 180 above and below. 
With SDTV and EDTV sources, 
the Dimension Digital Controller 
scales the image horizontally to 
achieve a 16:9 aspect ratio. 
Auto Cinema -- Select Auto Cinema to have the Dimension Digital Controller apply 
the Cinema aspect ratio to 2.35:1 source material automatically, 
when detected. To all other content, Auto Cinema applies the 16:9 
aspect ratio.

Picture Use the controls in the Picture Menu to calibrate each Dimension Digital Controller input to 
achieve optimum picture quality.
The Dimension Digital Controller 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 
Dimension Digital Controller input separately. 
Although it may be possible to obtain satisfactory picture quality using the naked eye and 
regular program material, Runco recommends using an external test pattern source 
(Ovation Multimedia, Digital Video Essentials or AVIA test DVD or equivalent) for best 
results.
Connect your test pattern source to the input that you are calibrating and proceed as 
follows. Perform the adjustments in the order listed here.
Picture
Brightness
Contrast
Color
Tint
Sharpness
Noise Filter
1. 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 and display mode separately.) For information about 
saving settings, refer to Memory Presets on page 74. 
2. For best results, Runco recommends that you set 
ConstantContrast (available only on the X-400d) to Off before 
adjusting Brightness, Contrast and other image quality settings in 
this menu (refer to ConstantContrast (X-400d only) on 
page 82). After you have completed the initial calibration, set 
ConstantContrast to On if desired.Note

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. 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.

11.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 adjust the tint, enable “blue only” display mode in the Diagnostics menu, as you would 
for adjusting color saturation (refer to the previous section, Color Saturation). 
Select Tint from the Picture menu and press ENTER. 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. 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.

Noise Filter: To apply noise filtering to the input signal, select Noise Filter from the Picture 
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.

Input PositionUse the controls in the Input Position Menu to fine-tune the aspect ratio and image 
position for the current source.
Left/Right: Select Left/Right from the Input Position menu to shift the projected image 
horizontally. Press  to shift the image to the right; press   to shift it to the left. 
Up/Down: Select Up/Down from the Input Position menu to shift the projected image 
vertically. Press  to shift the image upward; press   to shift it downward.
Width: Select Width from the Input Position menu to change the projected image width. 
Press  to increase the width; press   to decrease it.
Height: Select Height from the Input Position menu to change the projected image 
height. Press  to increase the height; press   to decrease it.
Overscan/Overscan Mode: 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.
For HDTV, DVDs and other video sources, Overscan is generally not necessary or 
desirable.
This control defines the amount of overscan applied to the image. The range is from 
0 to 20. There are two overscan modes: 
Crop mode, each increment adds a mask at the top, bottom, left and right edges of 
the source image equal to 0.5% of the displayed horizontal resolution (1% total). A 
setting of 10, for example, crops the image 5% on all sides or 10% total.
Zoom mode, each increment adds a factor to the scaling of the source image so 
that the vertical and horizontal resolutions are 100% plus 1% increments of the size 
determined by the aspect ratio function. A setting of 10, for example, zooms in on the 
image 5% on all sides or 10% total.
Figure 4-6 illustrates the effect of each overscan mode setting.

Figure 4-6. Overscan Modes
Phase (RGB, Component or SCART sources): This control adjusts the phase of the 
pixel sampling clock relative to the incoming signal. Adjust the phase when an RGB, 
Component or SCART image still shows shimmer or “noise” after Tracking has been 
optimized. 
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. Adjust the 
slidebar until the image stabilizes and each pixel is clearly defined. You may notice that 
you can stabilize the image at more than one point. Use either setting in such cases. 
Tracking (RGB, Component or SCART sources): Tracking determines the frequency 
of the pixel sampling clock, indicated by the number of incoming pixels per line, so that all 
pixels generated by a particular source are sampled. 
Steady flickering or several soft vertical stripes or bands across the entire image indicates 
poor pixel tracking. Proper pixel tracking helps ensure that the image quality is consistent 
across the screen, that aspect ratio is maintained and that pixel phase (see above) can be 
optimized. Adjust the Phase after adjusting Tracking (see below).
