Can someone confirm that 3-chip DLP projectors have no color wheel, and as such are suitable for high refresh rate page flipped 3d stereo with shutter glasses?

3 DLP projectors never have a color wheel because they already have a chip for red, green and blue component, therefore there's no need for a rotating color wheel.

Anyway, I don't know of a projector that is suitable for high refresh rate pageflipping, except those specially built for this purpose.

So, a 3-chip DLP may still not have a refresh rate above 60hz? I think my LP-150 has a 120Hz refresh rate max, but unfortunately it is the color wheel that is causing the stereo 3d effect not to work since it works at a lower rate (at least that is my understanding).

If a 3-chip DLP has a 120Hz refresh rate, then why would it not be able to be used with page-flipped shutter glasses?
