In addition to calibrating Red Green and Blue for a correct grayscale balance (6500K), there are a number of other settings that come into play. Typically Contrast and Brightness (white balance and black balance), need to be done first. Color saturation and gamma also need adjustment. In the case of the HC5020 projector, most of these default settings were fairly close to ideal, with only contrast altered more than slightly in most modes.
