The Home Cinema 700 has only a single control for each primary color - Red, Green, Blue. Most projectors, but not all, offer two controls for each, often called Gain and Bias. With two controls you end up being able to tune the projector a bit more tightly. I should note that one more expensive 720p competitor, the InFocus X9, has even less control than the Epson, with just a simple color temperature adjustment but no individual color control at all. Like this Epson, the InFocus manages some pretty impressive color accuracy.
