Runco Vx 6c Projector User Manual

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 eliminate
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...

FREQUENCIES HIGH/LOW affect the overall range of the CHROMA 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 CHROMA ENHANCE is on-screen.
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),...

A WIDESCREEN can be a number of aspect ratios; many movies are either 1.85:1 or 2.35:1, and HDTV
is always 1.78:1 (16:9). The way we create a widescreen (or LETTERBOX) aspect ratio is to take a full
4:3 image, then ‘blank’ (or cut off) the top and bottom so the displayed image is in a widescreen format.
For movies recorded in ‘letterbox’, there would be no information above and below the screen anyways,
so we’re not losing any of the picture. However, if you were to watch standard television broadcast...

Appendix A
This appendix defines the specific terms used in this manual as they apply to this projector. Also included are
other general terms commonly used in the projection industry.
Active Line TimeThe time, inside one horizontal scan line, during which video is generated.
