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.
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 (labeled as “cyan” and “magenta”) to match the middle short color bars (see color
bar drawing below).
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 (labeled as “white” and “blue”) to the outer short color bars (see color bar
drawing below).
BRIGHTNESS adjusts 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 (see lower left chart).
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.
CONTRAST adjusts the white level of the image. 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.
(see lower right chart).
