Re: DLP vs. LCD projectors for live performance

The biggest thing going against DLPs are the rainbow effect. DLPs
send out colors sequentially and when you're moving (which inevitably
you are in a club), you will see RGB color rainbows instead of the
image. To test, project a DLP on a wall and shake your head. It's
especially heightened for grayscale images. There are DLP models that
use 7 colors instead of 3 and I beleive they help mediate this effect.
 There are also more expensive 3 chip DLPs that don't suffer from this
problem at all.
