Runco Vx 3c Projector User Manual

While there are many different ways to connect your source equipment to your VHD
Controller, the examples shown above are the most common and are recommended by
Runco.
• 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 most VCR’s
and some camcorders; others such as Laser Disc players actually produce slightly better
results when using composite video. While the...

To get started using your VHD Controller and projector, follow these sim\
ple steps:
1.Ensure all sources that you are using are properly connected to the VHD
Controller. This is something your Runco dealer has probably already don\
e for
you; if not, please refer to the ‘Connection Examples ’ and the owners manuals of
each appropriate source as necessary.
2.Turn on all sources. If a A/V receiver is being used to switch the video\
, ensure 
that is also turned on.
3.Turn on the VHD Controller. Make...

QUICK SET-UP GUIDE
Overall Functional Description
The VHD Controller’s purpose is twofold. First, it provides aspect ratio control and
can do so on either a WIDESCREEN or a standard 4:3 screen. Second, it provides
a clean, progressive signal to the projector. 
The processing the VHD Controller uses is called SCALING. Scaling is simply a
way of taking a signal, ‘digitizing’ it, then converting it to any of a number of resolu-
tions. It is by manipulating the algorithms of the scaling process that we...

The main menu (shown above) includes two sections: Source Selection/ Picture
quality adjustments and Functional adjustments. Pressing MENU on the front panel
or on the remote control will bring up the main menu.
In the menu shown above, Composite video is selected as the current source. This
is indicated by an arrow to the left of ‘COMPOSITE’ in the menu. If S-video were
selected, for example, the arrow would then be to the left of ‘S-video’. 
To select a source, there are two options. First, using...

Aspect Ratioallows selection of one of the three aspect ratios provided by the
processor. You have two options for selecting an aspect ratio: First, highlight
ASPECT RATIO on the main menu, then press ENTER. Then select the desired
aspect ratio, and again press ENTER. The second option is to simply press the UP
or DOWN arrows on the remote or front panel. Doing this will toggle you through
the three choices- Anamorphic (16:9), Letterbox and Standard (4:3). For more infor-
mation on aspect ratios, please...

After pressing ENTER, the picture quality menu will appear (the menu to the right
of the main menu above). To adjust a certain function, highlight it with the or
DOWN buttons, and press ENTER. The following will then appear on-screen (we’ll
use COLOR as an example):

COLOR:    0
AGC ENABLED
To Change the value of the function (Color in this case), simply press the UP button to increase the
value, and the DOWN button to decrease the value. For COLOR and...

• SHARPNESS
This controls the ‘high-frequency’ detail of the image. The more sharpness is
increased, the more detail is added into the picture. However, if it is increased too
much, it will also increase ‘noise’ in the picture as well as other types of artifacts.
This may be set to personal preference; midrange is factory-preset.
• LUMA ENHANCE
This is similar to the sharpness control, but it does not boost the frequencies all
over the picture. Instead, this is more like an ‘edge enhancement’ that makes...

An ‘aspect ratio’ is simply the ratio of the width vs. the height of the screen. For
example, the current aspect ratio standard is 4:3 (or 1.33:1), where the image is 4
units wide and 3 units tall.
Aspect Ratios
First, the Basics
4 units wide
3 units tall
All of our ‘regular’ televisions are this aspect ratio. You have probably noticed that
occasionally you’ll watch a movie that does not fill the screen vertically. This is
because the movie was filmed in WIDESCREEN (letterbox), and the result is...

As you can see, our screen in this example is a 1.85:1 ratio. The dashed lines
show the area that we ‘blanked’. If you recall, watching a letterbox movie on a 4:3
screen gave us black bars; therefore with letterbox movies, we’re not losing any
information!
The ‘other’ type of widescreen is called ‘ANAMORPHIC’. The image is still a
widescreen format, but instead of ‘blanking’ the top and bottom, we simply reduce
the overall height of the image:
