1. How does Auto Brilliant Color work and at what level is it set at-High, Medium, or Low-is there a numerical value?
Here is a description of BrilliantColor (a Texas Instruments technology for their DLP chipset) from a HC3000 review. The implementation is the same in the HC3800:
"As announced by TI and reported here previously, BrilliantColor consists of a new color processing chipset and a new color wheel design that includes filters for both the three primary and three complementary colorsred, green, blue, cyan, magenta, and yellow. However, in this particular implementation, Mitsubishi has used TI's new BrilliantColor chipset and adapted it for use with a conventional six-segment RGB-RGB color wheel rotating at a 4x speed.
In operation, you can opt to activate or deactivate the BrilliantColor system by toggling On or Off in the menu. When BrilliantColor is activated, the picture becomes immediately brighter. Blacks and shadow values remain perceptibly unchanged while midtones and highlights increase in luminance by about 25%. All colors increase in luminance by the same ratio, and gray values do as well. Though midtones and highlights are brighter, there is no visible increase in color saturation. The result is that it opens up mid-tone information nicely. However, depending upon how it is calibrated and the screen size and material being used with it, it may overdrive the whites. A reduction in the contrast control may be required to bring the intensity of the whites down to a manageable level.
Most HC3000 users will opt to run with BrilliantColor engaged, as the picture typically looks a bit dull by comparison when it is not operating. However, this will depend on the material being displayed. For example, with material like HD sporting events, or the television series Lost in HD, or animated DVDs like Toy Story and Shrek, the BrilliantColor feature delivers a more engaging image overall. However, when we viewed a live indoor concert being broadcast in HD, the scene itself was already extremely high in contrast due to stage lighting and spotlighting. With this type of material the color and contrast appeared more natural with BrilliantColor deactivated. Thus, you will want to experiment a bit and find your own preferences."
I have found that toggling BC on and off with a white scale contast pattern on the screen, I can still see all the graduations of white. This will of course vary with your initial contrast setting etc.
