| Re: DLP vs LCD
I don't agree that you have to spend £5k either. Nothing like.
My first projector was an NEC LT75z with a 2x colour wheel. I used to see rainbows pretty frequently as did my wife and regular visitors to see a film. About 4 years ago I upgraded to a BenQ PE7700 which has a 4 or 5x speed wheel, I forget which. I can't remember seeing a rainbow since, nor can any of the people that did see them on the NEC. However I also have to say that even when I did see a rainbow it didn't bother me that much.
The BenQ cost about £1500 and that was 4 years ago. It would be significantly less now.
Have a demo with a pj that has a wheel of reasonable speed to see how it affects you.
It seems that the individual susceptibility to a) seeing the rainbow effect and
b) how irritating you find it varies widely. However I've never heard of nor seen a properly conducted study of the problem. In the absence of such a study any opinions you read are going to tell you more about the individual reaction to RBE rather than it's prevalence. What we can say for sure is that projectors with slow colour wheels will show the effect much more than those with 4x or faster wheels. The speed of a colour wheel is easy to check from specifications.
