The answer of course is 3 (dedicated RGB) DMD chips but that wouldn't be
cheap and there's not even too many movie theatres with that technology
yet - according to my 'digital source'! (Oldest son!)

All Digital Cinema projectors use 3 DMD chips, but it's certainly true that
few cinemas as yet are equipped for D-Cinema. Not only is the equipment
expensive, but there are relatively few "films" available in digital,
compared to good old 35mm film.
