I have seen the above used to discribe a problem with DLPs. Exactly what is it and is it bad enough to make one not purchase a DLP?

Older DLP systems and the "rainbow effect"

"""DLP chips exhibit an anomaly known as the “rainbow effect”. While this has been improved with faster color wheels over the years (2x is standard in most business projectors), some people will still be able to notice this effect. This is best described as brief flashes of perceived red, blue, and green "shadows" observed most often when the projected content features bright/white objects on a mostly dark/black background (the scrolling end credits of many movies are a common example). Some people would perceive these rainbow artifacts frequently, while others may never see them at all. With the advent of increased color wheel speeds or projectors featuring LED illumination, the “rainbow effect” has been virtually eliminated."""

From what i understand not everyone can see it. That is why mitsubishi went to the six color light engine.

"""One of the prime criticisms with DLP TVs is the fact that some (but not all) people notice streaks of color dubbed the "rainbow effect," especially if they're moving their eyes quickly across the screen. The 6-Color Light Engine seems to all but eliminate that potential streaking."""

I wouldnt let it deter me from purchasing a dlp. Just know its something that could be an issue.
