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 fil-
ter (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 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 CONTRAST and BRIGHTNESS, please refer to the PLUGE pattern below:
CONTRAST adjusts the white level of the image.Adjust contrast until there is a distinct defini-
tion between the two brightest bars.
NOTE: For best results, Runco recommends that CONTRAST be set to '0' or very close to it.
BRIGHTNESS
adjusts the black level of the image. To adjust this properly, adjust BRIGHT-
NESS 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 won't 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.
