"The traditional color wheel in most DLP business projectors has a four segment wheel, which is red, green, blue, and clear, or white. This type of wheel at 2x rotation speeds generates the highest incidence of rainbows. Since the wheel in the HD806 has three primary and three complementary colors, we would expect rainbow activity to be reduced. However, in practice we saw enough rainbow activity on the HD806 to cause us to suppose it had a 2x speed wheel. By comparison, the HD80 next to it in side by side viewing showed no rainbows at all." | "The traditional color wheel in most DLP business projectors has a four segment wheel, which is red, green, blue, and clear, or white.
