Color Saturation: On your external test pattern source, select a color bar pattern like the one
shown in Figure 4-5.
Figure 4-5. Typical Color Bar Pattern for Adjusting Color Saturation and Tint
Select Color from the Picture menu. While looking at the color bar pattern through a blue
filter, adjust the color saturation level until the outermost (gray and blue) color bars appear
to be a single shade of blue:
H. Sharpen/V. Sharpen (computer signals only): Select H. Sharpen or V. Sharpen from the
Picture menu to enhance the level of detail (in the horizontal or vertical direction
respectively) in a computer screen image.
Tint: Tint or “hue” is essentially the ratio of red to green in the color portion of the image.
When tint is decreased, the image appears redder; when it is increased the image appears
greener. To set the tint, select Tint from the Picture menu. While looking at the color bar
pattern through a blue filter, adjust the tint level until the cyan and magenta color bars (on
either side of the green bar) appear to be a single shade of blue.
