Auto SetupUse the Auto Setup feature of the SC-1 as a convenient starting point for calibrating the 
projector inputs for optimum picture quality. 
Auto Setup is an automated process in which the projector quickly optimizes critical 
display parameters such as size, position and pixel tracking, based on the type of 
incoming video signal. An Auto Setup allows you to quickly get the image “in the ballpark” 
after which you can perform further calibration, if necessary. 
To perform an Auto Setup, do one of the following: 
On the Theater Master Remote Control: Press FUNCS, then AUTO followed by 
ENTER. When the Auto Setup completes, press Enter again to keep the new settings. 
On the Projector Rear Keypad: Press AUTO SETUP followed by ENTER. When the 
Auto Setup completes, press ENTER again to keep the new settings. 
On the DHD Controller Remote Control: Press MENU, then select Service from the 
Main menu. Select Display Device from the Service Menu. Finally, select Configure from 
the Display Device menu, then select Auto Setup.

Auto Setup also optimizes the following settings, based on the characteristics of the 
incoming signal:
 Pixel Tracking 
 Pixel Phase 
 Size and Blanking 
 Vertical Stretch 

 Input Levels 
If additional fine-tuning is necessary after performing an Auto Setup, continue with the 
next section.
Size and Position Menu In the Size and Position Menu, you can increase or decrease the size of your image, 
change its proportion (aspect ratio), move the image to a specific area of the screen, and 
refine other related parameters. Use Size and Position controls to match the image 
precisely to the screen. Changes made in the Size and Position menu take effect 
immediately and are saved when you exit the menu.
Resize Presets: Select a Resize Presets option to quickly display an image in its native 
resolution, automatically resize an image to closely fill the projector’s native resolution or 
optimize the display width or height. 
The native resolution is 2048 x 1080 (1.90:1 native aspect ratio). 
Size, Position and Blanking parameters automatically adjust accordingly. If Blanking is set 
first, which defines an Active Input Area, Resize Preset scaling occurs in this region of 
interest only. 
The default setting is either No Resizing or Custom, depending on the input signal 
resolution. Do not change it unless specifically instructed to do so by Runco 
Technical Support. 
sizing: Select No Resizing to display the image in its native resolution, which 
may not match the projector’s resolution. For example, for a computer display with a 
native resolution of 800 x 600, “No Resizing” will use the central 800 x 600 pixels and 
have a black border— the black border areas are unused areas.

For 1080i digital and 1080p signals, channels are pre-configured at the Runco factory for 
each aspect ratio. These channels use Custom size presets to achieve the selected 
aspect ratio. 
stom” Resizing: The “Custom” re-size descriptor automatically appears in the 
Size and Position menu when any of the values for Size, Vertical Stretch, H-Position, 
V-Position or Blanking do not correspond to those for a preset. This option is not 
offered in the Size Presets pull-down list. 
Other resizing options are described below, for the sake of completeness. In actual 
practice, though, they are rarely (if ever) used when the SC-1 is used with the DHD 
Controller. 
 Default Resizing: When you select a new source, the image utilizes as much of the 
projector’s display area as possible for the type of incoming source data, but with 
minimal or no changes to aspect ratio. The image will be centered and displayed as 
large as possible depending on the source type: 
 A video image or graphic image is enlarged to fill the screen height, centered 
between black side bars. 
 An anamorphic (16:9) image will fill the height and slightly stretch horizontally to fill 
the small amount of display area remaining on both sides.
 Full Size: Select Full Size to use all pixels for displaying the image, regardless of 
source or original aspect ratio. Incoming source material having a different aspect ratio 
than the projector will be stretched to fill the display. 
 Full Width: Select Full Width to fill the projector’s display from left-to-right without 
changing the original aspect ratio of the image. Depending on the source, data at the 
top and bottom may be discarded (cropped), or the display may have black borders at 
the top and bottom (called “letterbox”). 
 Full Height: Select Full Height to fill the display from top-to-bottom. Depending on the 
source, this may create borders. 
Select Anamorphic to display an anamorphic image in its native 16:9 
aspect ratio. The image will fill the screen from top-to-bottom and be centered between 
narrow (64 pixels wide) black bars on each side.
Size: “Size” controls both the image width and height in tandem, maintaining the current 
aspect ratio (proportion) of the displayed signal data. 
Vertical Stretch: “Vertical Stretch” adjusts the height of the image while keeping the 
width constant. Use Vertical Stretch to change the aspect ratio of the display. 
Pixel Track: 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 can be optimized (see below). 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. 
By default, the projector samples at the correct frequency for most sources. 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 vertical stripes broaden to the point where one large stripe fills the image. If the 
image still exhibits some shimmer or noise, adjust Pixel Phase (described below).

Pixel Phase: Adjust pixel phase when the image (usually from an RGB source) still shows 
shimmer or “noise” after pixel tracking is optimized. Pixel phase adjusts the phase of the 
pixel sampling clock relative to the incoming signal. 
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; that is, you may find that the image 
appearance at “11” is identical to the image appearance at “38.” Use either setting in such 
cases. If some shimmer from a video or HDTV source persists, use the “
Filter” control in 
the Image Settings menu (described later) to remove high-frequency noise from the signal. 
H-Position: This option moves the image right or left within the area of available pixels.
V-Position: This option moves the image up or down within the area of available pixels.
Image Settings Menu Use options in the Image Settings menu to alter your image without affecting its size or 
position. Changes made in this menu are applied immediately and saved when you exit 
the menu. Options not available for the projector model or source are disabled and appear 
dim (gray). 
Contrast: “Contrast” increases or decreases the perceived difference between light and 
dark areas of your image (0-100). For best results, keep it under 50. If contrast is set too 
high, the light parts of the image lose detail and clarity. If set too low, the light areas will 
not be as bright as they could be and the overall image will be dim. For best results, start 
with a low value and increase so that whites remain bright but are not distorted or tinted 
and that light areas do not become white (“crushed”). 
Brightness: “Brightness” increases or decreases the amount of black in the image 
(0-100). For best results, keep close to 50. Start with a high value and decrease so that 
dark areas do not become black (“crushed”). Conversely, high brightness changes black 
to dark gray, causing washed-out images. 
Gamma: “Gamma” is a global setting that determines how gray shades are displayed 
between minimum input (black) and maximum input (white) for all signals. The normal 
gamma setting of 2.2 is correct for virtually all signals and conditions. If excess ambient 
light washes out the image and it becomes difficult or impossible to see details in dark 
areas, lower the gamma setting to compensate. 
Adjust “Pixel Tracking” before “Pixel Phase.”
The values shown represent where the approximate center of the 
image lies in relation to the total number of pixels available 
horizontally or vertically. This varies widely according to the signal; 
watch the image while adjusting.

Filter: The proper filter setting is automatically set for virtually all signals, and rarely needs 
to be changed. It applies a low pass filter for noise reduction in the incoming input signal, 
particularly for HDTV or SDTV. Applied in the analog domain before sampling, this filtering 
removes high frequencies and thus reduces pixel phase noise (note this also reduces 
signal bandwidth). Override only if standard pixel tracking and phase adjustments do not 
adequately clear up a “noisy” video signal, or if a graphics signal appears overly “soft.” 
Both instances indicate that “Filter” may be set to the wrong option. 
Detail: “Detail” adjusts the sharpness of a video image so that edges remain clearly 
defined. It can be particularly useful if a significant “Noise Reduction” adjustment has 
caused the image to appear too soft. Adjust until the display is as sharp as desired, 
keeping in mind that because “Detail” adds some high frequencies back into the image, it 
can also reintroduce a certain degree of noise. 
Noise Reduction: Noise Reduction is similar to the “Filter” control, but operates in the 
post-sampling digital domain with a more subtle effect. Higher settings are most useful for 
clearing up noisy RGB images such as those from a PC. Adjust as desired, keeping in 
mind that reducing noise (which reduces high frequencies) may also soften the image. 
Color Space: “Color Space” determines how the color components of an analog input 
signal are decoded for accurate color in the display. With the SC-1, this should always be 
set to RGB. 
Video Options: This sub-menu is not applicable to the SC-1.  
Input Levels: Good RGB or input levels — that is, the drives and black levels for each of 
the three primary colors, red, green and blue — ensure that images from analog sources 
other than decoded video have maximum contrast without crushing black or white.
By default (and in an “Auto Setup”), the projector automatically determines the best input 
levels by monitoring image content and adjusting the controls appropriately; further 
adjustment is typically not required to obtain proper blacks or whites. 
However, for a very unusual source exhibiting one or more overly high black levels 
(typically caused by a noisy source causing black level spikes), an experienced technician 
may prefer to use the Input Levels menu (shown above). These adjustments, which 
together serve as a calibration process compensating for differences in sources and 
cabling, enable an experienced technician to perfect the source image input levels and 
eliminate the “overshoot” and “undershoot.” 
1. The White Balance controls are of limited use with digital signals, 
but do offer some ability to tweak poorly mastered source 
materials.
2. Because the projector automatically optimizes input levels for all 
but the most unusual of sources, it is recommended that only 
experienced technicians use the Input Levels submenu.
3. Before beginning, check that overall contrast and brightness 
settings are near 50 and that color temperature is properly set 
using an internal grayscale test pattern.

 Auto Input Level: Keep off for virtually all sources (default). Temporarily enter a check 
mark only if you are an experienced technician and you have an unusual source that 
you feel needs further color temperature and/or input level adjustment. After entering a 
check mark, wait for the six slidebar values to stabilize, then clear the check mark and 
exit. This compensates for incoming out-of-range drives (white) and black levels (black) 
that would cause “crushing” of light and dark colors in the image. 
s and Drives: To check your image and adjust these controls: 
1. Make sure overall “Contrast” and “Brightness” settings are both set to near 50. (Not 
required for “Auto Input Level” adjustment.) 
2. Check the color temperature setup using an internal grayscale test pattern, making 
sure to obtain a neutral grayscale. (Not required for “Auto” adjustment.) 
3. If the blacks and/or whites appear OK, input levels do not need adjustment. If black 
levels are too high (and/or whites are too low, which is rare), you likely have a noisy 
source that is producing skewed input levels. Continue with Step 4. 
4. Temporarily enable “Auto” in the Input Levels submenu. Wait for all six values to 
stabilize. Alternatively, do not use “Auto” — reduce black levels manually instead. 
Judge by eye and change one or more of the six levels as necessary to obtain 
proper blacks and whites. You may want to see only a certain color while adjusting; 
if so, use the “Color Enable” option (described below). 
5. Delete the “Auto” check mark and exit the Input Levels menu. 
 Auto Color Enable: When a check mark is present, selecting a specific black level or 
drive to adjust will automatically enable the corresponding color in the display. Delete 
the check mark to see all colors. 
 Clamp Location: This option can brighten the image produced from certain 
high-resolution, high-frequency graphic sources. For almost all sources, the best clamp 
location is automatically selected by the projector. 
 Use the normal Back Porch location if the image is either sufficiently bright or overly 
bright. 
Sync Tip if the image appears unusually dim, if there are horizontal streaks 
across the image, or if there is significant color drift. This moves the clamping pulse 
from the normal back porch location (which is likely too short) to the tip of the 
horizontal sync pulse. 
Tr i  L e v e l is typically recommended for an HDTV source where the back porch is 
also short, or for video sources or any RGB source with sync information included 
on the video (for example, sync-on-green). 
1. There must be at least two consecutive white pixels present in 
the image for the “Auto Input Level” function to work properly. 
Otherwise, input levels may produce skewed colors, particularly 
in non-video images.
2. Uncheck this item before exiting this menu.

 Peak Detector: The Peak Detector is a tool to assist with defining individual input 
levels, enabling you to accurately set the white balance for any particular source with 
the appropriate image. 
Enabling the Peak Detector activates a special operating mode for detecting only pixels 
that are considered black or white; all other levels are displayed as a mid-level gray. 
When used with a smooth grayscale pattern in which black and white are known to be 
at opposite edges of the image, you can watch these isolated areas while adjusting 
individual black and white levels until both black and white edges are just visible and 
distinguished from neighboring pixels. Images from this source will then display correct 
blacks and whites without crushing. 
Figure 3-33. Adjusting Black Levels and White Levels Using the Peak Detector
1. Display a 16-level grayscale test pattern from the DHD Controller. 
2. Enter a checkmark in the Clipping Detector checkbox.  
3. Display one primary color.  
4. For the current color, adjust its corresponding “Black Level” slidebar just until a single 
band of black appears at one edge of the screen. This band represents the first band of 
the grayscale pattern, which should be 100% black. Do not adjust too far. 
5. With the same color still active, adjust its corresponding “White Level” slidebar just until 
a single band of color appears at the opposite edge of the screen. This band 
represents the last band of the grayscale pattern, which should be 100% white (or the 
current color, if a certain color is enabled). Do not adjust too far. 
The Clipping Detector will initially render the grayscale as a uniform 
gray field before adjustment or extreme crushing.
Selecting Auto Color Enable ensures that the correct color is 
displayed for each setting.
4.  Adjust corresponding
     black level (red, green or 
     or blue) until one black 
     band appears.

Working With the 
Lamp 
Access the Lamp menu to: 
 Choose a lamp mode for regulating power and light output. 
 View information pertaining to past and present lamps.
 Record the lamp serial number in the projector’s memory. 
Lamp Hours (read-only): Lamp Hours shows the number of hours logged on the 
current lamp. Whenever you record a new lamp serial number, the SC-1 automatically 
resets this value to “0” and begins to log time for the new lamp. 
Lamp S/N (read-only): Lamp S/N is the serial number recorded for the current lamp. 
When you install a new lamp and enter its serial number, the number appears here.
Lamp Message: Enter a check mark for Lamp Message to enable a warning message 
that appears upon power-up when the lamp has reached the specified lamp limit and 
should be replaced. Delete the check mark to prevent display of this message—instead, 
when your lamp expires, only the status display messages on the back of the projector will 
provide a visual warning to replace the lamp. 
Readjusting the black levels affects the gain at this point; only 
readjust when absolutely necessary.Note
1. It is recommended that the Lamp Message check box remain 
enabled. 
2. When a lamp warning message appears, press EXIT to 
temporarily cancel the message. The message will continue to 
appear upon power-up until you install a new lamp.

Lamp Limit: Set Lamp Limit to the number of hours you expect to log on the current 
lamp before replacing it. This will trigger a lamp message on-screen (if enabled). 
Lamp Mode: Select the Lamp Mode you want to use in order to control the light output. 
You can choose to run the lamp as bright as possible, you can power the lamp with a 
specific wattage appropriate for the installed lamp or you can set a specific intensity 
(brightness) to maintain. Keep in mind that higher lamp power settings can shorten lamp 
life. 
Use the lamp mode that best suits your brightness needs: 
 Max Brightness: The lamp will always burn as brightly as possible, driven by 100% of 
the power level rating for the installed lamp. Keep in mind that the “maximum 
brightness” for any lamp gradually diminishes with the “Intensity” option. 
sity: Brightness will remain close to a specified level for as long as possible. If you 
select this option, enter a number representing the intensity level (brightness) you want 
to maintain — the SC-1 automatically adjusts power as needed to maintain this 
intensity as closely as possible. 
This value and slidebar represents the current brightness of your lamp, decreasing over 
time when you are operating in Max Brightness mode or at a specific Power level. 
When you operate in Intensity mode, this value remains at the chosen Intensity setting 
and cannot be adjusted. 
To use “Intensity” mode, judge by eye (or use a meter) and set the level as desired for 
your application. Over time, the projector will automatically increase the power supplied 
to the lamp as needed to maintain the chosen intensity as closely as possible. 
The power supplied to the lamp will remain at your specified wattage level. 
Once you select this option, enter the number of watts representing the power level you 
wish to maintain.
This slidebar and number indicates how many watts are applied to the lamp. You can 
apply anywhere from approximately 60 to 65% of the maximum power intended for the 
installed lamp up to 100% of the lamp rating. Set for the number of watts as desired, 
keeping in mind that lower power levels produce dimmer images. When in either Power 
or Max Brightness modes, the power level remains constant. Specifying a maximum 
power level here is the same as operating in Max Brightness mode. 
1. If you change modes over the life of a lamp, the lamp limit you 
originally expected may no longer be possible. 
2. Turning the lamp on and off reduces lamp life significantly, as do 
other factors.
3. It is recommended that Lamp Limit not exceed the expected 
lamp life, otherwise a lamp could become dangerously fragile 
with overuse.
Note
The Intensity value is not the actual lumen output, but rather a 
correlated value only—1246 may represent 3500 lumens, for 
example. Note

HOW LONG CAN I MAINTAIN BRIGHTNESS? The SC-1 can maintain your “Intensity” 
setting until the required power reaches the maximum rating for the lamp. The lower the 
setting, the longer it will take to reach this threshold and the longer you can maintain the 
desired brightness. Keep in mind that once the lamp power reaches its maximum wattage 
(see “Power,” above), this tracking is no longer possible. At this point, the lamp will 
gradually begin to dim as usual, even though your original “Intensity” value will still appear 
in the menu. To resume accurate tracking, reduce the intensity setting so that the resulting 
“Power” value is less than its maximum—the lower the intensity, the longer it can be 
maintained. 
For example, a 2000-watt lamp can be driven at no more than 2000 watts. To produce 
desired brightness at the screen, a new lamp would likely need less than this maximum 
rating — perhaps 1700 watts (example only). Over time, however, the lamp requires more 
and more current in order to generate the desired light, until eventually the lamp wattage 
reaches its 2000-watt maximum and the lamp power automatically levels off. At this point, 
the tracking function terminates (that is, the power level stabilizes) and the lamp begins to 
dim normally. Either reduce your “Intensity” setting or replace the lamp. 
Do not lower the “Intensity” so much that the corresponding “Power” value reaches its 
minimum — the intensity setting will be inaccurate and cannot be maintained. 
Lamp History (read-only): Lamp History shows the lamps most recently installed and 
recorded in the projector. The Lamp History automatically updates whenever you record a 
new lamp serial number; the new lamp is added to the end of the list. 
Change Lamp: Select Change Lamp from the Lamp menu to record the serial number 
for a newly-installed lamp. For detailed lamp replacement instructions, refer to 
Lamp and 
Filter Replacement on page 91. 
LampLOC: Select LampLOC from the Lamp menu to adjust the position of the lamp 
relative to the remainder of the illumination system, to maximize light output. For 
instructions on using LampLOC, refer to 
Maximizing Light Output on page 46. 
1. Lamps become more stable over time, thus a specific intensity is 
more easily maintained as the lamp ages.
2. Intensity can be set only if the lamp is in “Intensity” mode 
3. Intensity cannot exceed the output of Max Brightness mode.
