2 SCREEN ADJUSTMENT
2. To allow specific adjustments to Red, Green and Blue (R/G/B)
Consists of the Cutoff and Gain functions.
Cutoff and Gain adjustments
Monitors use red, green and blue (R, G, and B) to convey color information. They use
an additive method to combine different amounts of the primary colors to produce a
desired color. In other words, monitors start with no light (black) and add
percentages of red, green and blue to make colors. White is usually produced by
adding the same amount of all three colors, where black is usually produced by
adding no color.
However, colors are not only determined by the balance but also the intensities of R,
G, and B (how bright they are) which we call Gain, and the saturation of R, G and B
(how vivid or dull they are) which we call Cutoff.
· If only a quick setting is required, that is close to the desired color, but not exact, skip
making any changes to the Cutoff adjustment (step 4). If a precise match is desired,
adjustment of the Cutoff levels must be made. We recommend that for exact match-
ing, use a color calibrator.
