When Test patterns are selected, the actual colours displayed may depend on the settings of the contrast, brightness and gamma controls. It may be necessary to set all brightness controls to 0.0, and all contrast controls to 1.0, before making any light level measurements. There are two ways of creating a blank screen: Shutter closed: the screen is completely black. All black test pattern: all pixels are set to off, but there may be an extremely small amount of light leakage through the prism and DMD assembly.

To go back to a previous menu option that is no longer visible, call up the menu again using the appropriate Main menu button. The contrast, brightness and gamma controls in the Image menu are all interactive, so settings made with one control may directly affect the setting of another control. All these controls allow extreme settings to be made. However, in normal use, it should never be necessary to set any of the controls far from midpoint. If in doubt, reset the contrast, brightness and gamma controls to midpoint, then make your adjustments in small steps. Better still, use the AUTO feature. Image menu... Contrast Controls Contrast sliders Menu buttons... Shutter open Shutter close Contrast Brightness Gamma Test patterns Advanced image setup Contrast Press the CONTRAST button: To adjust the OVERALL, RED, GREEN or BLUE contrast settings, touch and drag the sliders up and down or for fi ne adjustment, press the arrow heads. To reset a slider to its midpoint (1.0), press on the numerical value. The numerical values displayed, ranging from 0 to 2.0 are not absolute, but relative values. When the OVERALL slider is used, all three colours on the projected image will change, but the individual values displayed on the sliders will not. To maintain optimum overall image contrast and light output, press the AUTO button. The OVERALL slider will grey out and become inoperable. The actual contrast settings will be automatically adjusted such that your colour balance settings are maintained but the optimum contrast and light output will be achieved.
