Advanced Image Settings — SUBMENU

Use the Advanced Image Settings submenu to make the adjustments necessary for lesser-used but more specialized applications on your projector.

GAMMA TABLE: This control applies

a default video, graphics or simple gamma table or “curve” to your images, controlling the intensity of mid-level colors and producing

maximum contrast, brightness and color

performance. As shown at right, the graphics curve is a modified power curve that will show more detail in darker areas of the projected content while the video curve has a linear

segment near black to compensate for increased black levels typical of video

signals. A simple gamma curve is a true

power curve that does not alter the contrast or the intensity of mid-level colors. Although the projector automatically applies either the graphics or video curve according to what type of incoming signal is detected, in some cases you may wish to override this default and use graphics gamma for a video source or video gamma for a graphics source. Alternatively, if neither default is ideal, you may prefer to apply the simple (non-optimized) gamma curve or a user-defined custom gamma curve that has been created externally, named, and downloaded to the projector (requires separate PC-based Arbitrary Gamma and KoRE Librarian software applications). If any of these special user curves have been installed, their names will appear in the Gamma Table pull-down list.

Keep in mind that any Gamma Table choice sets the related Gamma value (shown in the Image Settings menu) to a 2.2 default, where it can be fine-tuned as desired. Different values (1-3) here indicate that the original gamma table has been adjusted with either the Gamma slide bar or direct key.

	NOTES: 1) If no user curves have been defined and downloaded to projector memory,
	only the 2.2 default gamma curve is available here – adjust as desired using gamma
	in the main Image Settings menu. 2) Some graphic material will look best with the
	video setting while some video material is best with the graphic setting.
	SELECT COLOR ADJUSTMENT: In “Select Color Adjustment”,
	choose an overall color palette for all images. The “Max
	Drives” factory default simply drives all 3 colors at their
	maximum level so that they are fully on and cannot be
	changed. The two other pre-defined color adjustment
	choices—SD Video and HD Video—apply a color gamut
	optimized for video sources (standard or high-definition).
	Alternatively, you can specify a color temperature. This
	enables the adjacent Color Temperature slidebar and applies
	its current setting (default = 6500K). If none of the pre-defined “Select Color
