Submenu Advanced... Functions and Descriptions • Black Level Sets the picture grayscale to 0 IRE or 7.5 IRE. The grayscale video signal is measured in IRE units. In some areas which use NTSC TV standard, the grayscale is measured from 7.5 IRE (black) to 100 IRE (white); however, in other areas where PAL equipment or Japanese NTSC standards are used, the grayscale is measured from 0 IRE (black) to 100 IRE (white). We suggest that you check the input source to see if it is with 0 IRE or 7.5 IRE, then select accordingly. • Gamma Selection Gamma refers to the relationship between input source and picture brightness. • 1.6/1.8/2.0/BenQ: Select these values according to your preference. • 2.1/2.2: Increases the average brightness of the picture. Best for a lit environment, meeting room or family room. • 2.3/2.4: Best for viewing movies in a darkened environment. • 2.6/2.8: Best for viewing movies which are mostly composed of dark scenes. High Brightness Low Contrast Low Brightness High Contrast 1.6 1.8 2.0 2.2 2.4 2.5 2.6 2.8 • Brilliant Color This feature utilizes a new color-processing algorithm and system level enhancements to enable higher brightness while providing truer, more vibrant colors in picture. It enables a greater than 50% brightness increase in mid-tone images, which are common in video and natural scenes, so the projector reproduces images in realistic and true colors. If you prefer images with that quality, select On. If you don't need it, select Off. • Color Temperature Fine Tuning Allows you to manually adjust the pre-defined color temperature modes: 1. Press OK to display the Color Temperature Fine Tuning window. 2. Press ▲/▼ to highlight the item you want to change and adjust the values by pressing Red Gain/Green Gain/Blue Gain: Adjusts the contrast levels of Red, Green, and Blue. • Red Offset/Green Offset/Blue Offset: Adjusts the brightness levels of Red, Green, and Blue. 3. When done, press OK and BACK to exit. The function is accessible through the remote control. 48 Menu Functions
