White Peaking

™The “Signal” sub menu is supported under the Analog RGB and Analog YPbPr input sources.

Use the white peaking control to set the white peaking level of the DMD chip. “0” stands for minimal peaking, and “10” stands for maximum peaking. If you prefer a stronger image, adjust toward the maximum setting. For a smoother, more natural image, adjust toward the minimum setting.
