Runco Vx 6c Projector User Manual

							Congratulations on your purchase of the VHD Ultra Controllervideo processor with Vivix™ technology! This
processor is designed to maximize the image quality of your fixed-pixel display or rear-screen television while
adding an extra level of flexibility to your system.  The VHD Ultra ControllersVivix™ processing techniques
enable this processor to be used most efficiently with fixed-pixel displays, and will provide the most stunning
image that your display can possibly deliver.
Vivix™ is a proprietary technique developed by Runco engineers to match the output resolution of the proces-
sor precisely to the display it will be used with. This precision processing technique resolves all the problems
that conventional video processors have with fixed-pixel displays, which include pixel-tracking
artifacts (jagged lines, moiré, jerky motion, etc.), too much overscan (significant loss of image) and even
improper and disproportionate aspect ratios. The results of Vivix™ technology is an image that nearly rivals
that of a CRT, while providing three geometrically-correct aspect ratios on a 16:9 or a 4:3 screen.
The VHD Ultra Controllerhave many great features and benefits that make it a flexible, high-quality
processor. Its many benefits include:
• Vivix
TMTechnology, which maximizes image quality and flexibility of fixed-pixel displays.
• An adaptive 2-dimensional comb filter that greatly reduces artifacts when using a composite video signal as   
an input.
• A Luma edge enhancement circuit makes the edges of objects appear sharper without the ringing and
noise increase associated with traditional sharpness circuits
• A Chroma edge enhancement circuit is included to compensate for lower chroma resolution found in com-
posite and S-video.
• Inverse Telecine (3:2 pulldown) detection and processing allows the scaler to almost completely eliminate
interlace artifacts associated with other scalers
• The controller can correctly scale anamorphic, letterbox and 4:3 formats to fit on a wide aspect-ratio screen,
and scale anamorphic formats on a 4:3 screen
• A pass-through connector is supplied for routing HDTV or computer graphics directly to the display. 
• An RS-232 input is provided for easy integration into the automated home theater environment
• A TBC (Time Base Corrector) circuit is provided for unstable sources such as VCR’s.
•  12V outputs are provided for drop screens and screen masking. 
• A simple 7-button remote controls all aspects of operation. One button source selection and aspect ratio
control is also provided via the remote control.

REMOTE CONTROL DESCRIPTION
6-8 
						

							While there are many different ways to connect your source equipment to your VHD Ultra Controller,
the examples shown above are the most common.
• COMPOSITE VIDEO INPUT:
Composite video is the most common type of signal used, but is also the lowest in picture quality. Many
sources have outputs that are limited to composite video, such as some VCR’s and camcorders; others
such as Laser Disc players actually produce slightly better results when using composite video. 
• S-VIDEO INPUT
S-video is the second-best type of signal that can be used, but is MUCH better than composite video.
Using such sources as Satellite receivers, high-quality VCRs and DVD players (with no component
output) will produce a MUCH cleaner and sharper signal.
COMPONENT INPUT
Component video is the best type of signal that can be used. The most common sources that use com-
ponent outputs are DVD players, and it is highly recommended that component be used when possible.
Component video goes one step beyond S-video in picture quality; chroma (color) information is more
resolved and the overall picture appears more well-defined.
• PASS-THROUGH
This input is used to ‘pass-through’ any high-definition or computer signals that do not require process-
ing. The signal by-passes the VHD Ultra Controller’sprocessing and is sent directly to the display. The
pass-through may be used for COMPONENT outputs from a DTV decoder, a progressive-scan DVD play-
er or RGB outputs from a computer or other high-resolution sources.

							When the MENU button is pressed on either the remote control or the front panel, the main menu will
appear on-screen. An example of the main menu is shown above.
The active source is indicatedby an arrow to the left of the source; note that in the example above,
Composite is the current source.
To select a source via the main menu,press either the up or down buttons on the remote or front panel
and highlight the desired source, and press ENTER. Otherwise, you may select a source by pressing
either the left or right arrow buttons (on the remote or front panel) when no menus are
on-screen, or by pressing one of the direct access buttons on the remote control (recommended; see page
6-8).
If pass-through is selected,note that no on-screen menus will be displayed since the signal is simply
being looped directly to the output. When pass-through is the selected source, pressing MENU will auto-
matically select the last selected input before Pass-through was selected. If you wish to choose another
source, Runco recommends using the direct access buttons to select the desired source as opposed to
pressing MENU.
Aspect Ratioprovides selection of one of three aspect ratios: Anamorphic, Letterbox or standard 4:3. To
select an aspect ratio via the main menu, press either the up and down buttons on the remote or front
panel, highlight ASPECT RATIO and press ENTER. The aspect ratio menu will then appear with the three
choices; highlight the desired aspect ratio with the up or down buttons and press ENTER. Otherwise, you
may select an aspect ratio by pressing either the up or down arrow buttons (on the remote or front panel)
when no menus are on-screen, or by pressing one of the direct access buttons on the remote control (rec-
ommended; see page 6-8).
Installationis where the image shift and blanking controls are located. A full description of this menu is
on page 6-13. 
NOTE:If INSTALLATION does not appear on the main menu, see page 6-13 for an explanation on how
to access the Installation menu.

							Picture quality adjustments (also known as Front Panel Controls) are the controls that change different
parameters of the image such as the amount of color, black level, etc.  While these adjustments can be set to suit
the needs of the user, there is a way to set these properly. This section will describe what each function does and
how to adjust them properly.
To access the picture quality adjustments, press MENU, highlight the active source (indicated by the arrow) and
press ENTER. The picture quality sub-menu will then appear (see above).
To make an adjustment to a particular function, highlight the function with the up or down arrow buttons and press
ENTER. Once the function is on-screen (i.e. brightness), pressing the UP arrow button on the remote or front panel
will increase the value of that function; pressing the DOWN arrow on the remote or front panel will decrease the
value of that function.
While each of the picture quality adjustments can be set to suit the needs of the user, there is a proper way to set
the adjustments.  For setting TINT and COLOR, please refer to the color bar test pattern below.
NOTE:Runco recommends that a BLUE FILTER be used so only the blue color bars can be seen. Blue filters are

(www.imagingscience.com).
TINT(also known as hue) is essentially the ratio of red to green in the color portion of the image.
If TINT is decreased, the image will appear redder, and increasing it will cause the image to appear green-
er. To set TINT properly, look at the color bar pattern through a blue filter (or mute the red and green out-
puts). Adjust TINT until the middle two tall color bars match the middle short color bars
(see color bar drawing).
COLOR(also known as saturation) increases or decreases the amount of color in the image. To set
COLOR properly, look at the color bar pattern through a blue filter (or mute the red and green outputs).
Adjust COLOR until the outer two tall color bars match the outer short color bars
(see color bar drawing).
For setting CONTRASTand BRIGHTNESS, please refer to the PLUGE pattern below:
CONTRASTadjusts the white level of the image. To adjust this properly for CRT projectors, adjust CON-
TRASTuntil there is no blooming (or distortion) in the brightest bar in the PLUGE pattern (see above).
For Fixed-pixel displays, adjust contrast until there is a distinct definition between the two brightest bars.
NOTE:For best results, Runco recommends that CONTRAST be set to 0 or very close to it.
BRIGHTNESSadjusts the black level of the image. To adjust this properly, adjust BRIGHTNESS until the
below black bar JUST disappears, but the above black bar is still barely visible.

							NOTE:Some DVD players cannot pass the blacker than black bar (they wont pass PLUGE), and that
bar will never be visible. In a case like this, adjust the above black bar until it is slightly brighter than the
background that surrounds it.
SHARPNESSadjusts the amount of high-frequency detail in the image. This can be adjusted to the pref-
erence of the user. Keep in mind that when SHARPNESS is decreased, fine details in the image will
become soft; when it is increased, fine details will become sharper but will also make the picture appear
noisy if adjusted too high.
LUMA ENHANCEacts as an edge enhancement, especially around black to white transitions in the
image. Essentially, this has the same characteristics as sharpness but affects the edges of objects far
more that the rest of the image.
FREQUENCIES HIGH/LOW affect the overall range of the LUMA ENHANCE feature. For example, if
using a lower-quality video source such as a VCR, the FREQUENCIES should be set to LOW. For a good
quality source such as a DVD player, set FREQUENCIES to HIGH. To set FREQUENCIES, press ENTER
while LUMA ENHANCE is on-screen.
CHROMA ENHANCEacts as an edge enhancement, especially around color transitions in the image.
Essentially, this has the same characteristics as sharpness but affects the edges of objects far more that
the rest of the image.
The Installation menu is where you can adjust the type of screen (4:3 or 16:9), shift the image or set blank-
ing.
When the VHD Ultra Controlleris turned on for the first time, the INSTALLATION item will not appear in
the main menu. To enable the INSTALLATION menu, there are two options:
·With the processor ONand no menus on-screen, simultaneously press the ENTER, UPand LEFT
buttons (you dont need to hold them down). Release the three buttons and press MENU, ensure INSTAL-
LATION is now on the bottom of the main menu.
·With the remote control, press button 6 (with no menus on-screen). After pressing 6, press MENUand
ensure INSTALLATION is now on the bottom of the main menu.
