How can you NOT see the 'rainbows'?
DLPs use frame sequential scanning. Red, Green, Blue.
If you move your eyes you see the individual colors
at high contrast (black-white) boundaries. Annoying as heck. And if it's an action movie, you're moving your eyes. Wish I'd known that before I bought mine (but the contrast and lumens specs were WAY better than a comparably priced LCD).

The majority of people simply don't see them.  The newer projectors that have more segments in the colour wheel and higher colour wheel speeds are way better than the older ones in this respect.
