Could anyone advise if modern DLP's still suffer from what I think was called the Rainbow Effect? If memory serves me correctly not everyone's vision is sensitive to it (bit like the headache comment) although I was. Sometimes during fast moving scenes there would be some subtle (and fast, almost imperceptible) bands of colour distortion.”
It's much less than it used to be. But not everyone has the problem.
It depends on a thing called the "colour wheel", and how quickly it rotates to provide the colour/image. 2x / 3x / 4x / 5x are the typical speeds, although 6x is available.
I have an old 2x DLP projector which is nice in every way but for the fact it gives me a mild headache after about 1hr use
A different DLP projector with 4x colour wheel causes no trouble at all, although I can still see the rainbows sometimes.
This projector can also do 5x and it's really hard to see rainbows at that speed.
