Section 3: Operation

Contrast

Select Contrast when you want to increase or decrease the perceived difference between light and dark areas of your image (0-255). If contrast is set too high, the light parts of the image loses detail and clarity. If the value is set too low, the light areas will not be as bright as they could be and the resulting image will appear dim. Start low and increase so that whites remain bright but are not distorted or tinted, and that light areas do not become white (i.e., are “crushed”). For best results, keep close to 128 for graphics (mid-range value).

SHORT CUT: Press Contrast and adjust the slidebar.

Brightness

Select Brightness when you want to increase or decrease the amount of black in the image (0-255). Start high and decrease so that dark areas do not become black (i.e., are “crushed”). Conversely, high brightness changes black to dark gray, causing washed-out images. For best results, keep close to 128 for graphics (mid-range value). The value will differ for video sources.

SHORT CUT: Press Brightness and adjust the slidebar.

Pixel Phase

This is the same option that appears in the Size and Position menu and can be adjusted in the same manner.

Color Setup
