    Subject: Query about projectors for stereo

    Hi,

            I am looking to buy a video projector to generate large-field
    stereoscopic displays using frame alternation. The 3-chip DLP projectors
    seem ideal (bright, no persistence, all optical), but are very large and
    expensive (>$50k). I guess that a 1-chip DLP projector would work if I
    removed the color wheel, but these projectors seldom have refresh rates
    above 60Hz. I think (but am not certain) that LCD projectors would not
    work well because they are slow (long equivalent persistence).
            If anyone has any experience to share or advice about which way to
    go, I would most appreciate hearing about it.

    Thanks,
    Greg DeAngelis
