Runco Vx 5c Projector User Manual

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...

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...

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...

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
greener. To set TINT properly, look at the color bar pattern through a blue filter (or mute the red and
green outputs). 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...

SHARPNESSadjusts the amount of high-frequency detail in the image. This can be adjusted to the
preference 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...

When you are installing the system for the first time, the first order of business is to define what type of
screen will be used with this system. If a 1.78:1 (16:9) or 1.85:1 screen is used, highlight 16:9 SCREEN and
press ENTER. If a standard 4:3 screen is installed, highlight 4:3 SCREEN and press enter.
The purpose of defining the screen type is to tell the processor how to create aspect ratios (see page 6-16
for a definition of aspect ratios). For example, on a 16:9 screen, the letterbox and...

The BLANKINGfunction allows you to cut off part of the image to fit the screen properly, or to elimi-
nate anomalies on the extreme outsides (usually the top) of the image. This can be done to the top,
bottom, left or right sides individually.
To adjust BLANKING, highlight the desired area you wish to blank (top, bottom, left or right),
and use the left and right arrows to make the adjustment.
Most CRT projectors themselves have blanking controls, and it is recommended that you use the
controls on the...

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
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 ‘black bars’ above and...

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:
Blanked (cut off)
areas Active image area
