Hi mpyw,

Only single-chip DLP-based projectors with a spinning colour wheel produce rainbow effects (commercial DLP projectors in cinemas use 3 DLP chips and no color wheel so no rainbow effects). The LCoS and 3-LCD projectors you mention do not use color wheels.

I've not seen the Epson so you'll need to get feedback from other forum members. I've been most impressed by the Panasonic line of front projectors but it's been some years since I viewed JVC units.

Regards,
Alan
